1.1 Introduction

The information contained in this publication relates to the current status oftechnology in respect of relevant British, German and other European stan-dards currently in force. The publication date of this brochure can befound on the cover page.

1.2 Quality Standards

OWAcoustic® ceilings consist of wet felted mineral wool tiles and panelstogether with an appropriate metal grid suspension system suspended fromthe building structure by the correct method of attachment. OWAcoustic® cei-ling tiles and panels are manufactured from natural materials and do not con-tain any harmful substances such as asbestos or formaldehyde. OWAcoustic® ceilings are complete systems tested to the latest standardsand regulations. 50 years experience of continuous production of mineralwool tiles means that OWA has kept pace with the ever changing demandsof the ceilings market.

OWAcoustic® quality standards:

OWAcoustic® ceiling tiles are manufactured from high quality materials and finis-hed with latex base paint. Of significant importance, the OWA white wool fib-res have tested Bio-persistence (Bio-solubility) levels that fully comply with theEuropean directive 97/69/EC (Certificate available on request) and are there-fore free from health risk.OWAcoustic® ceilings are quick and simple to install, conceal services withinthe cavity void and will facilitate the integration of essential services such aslighting, air handling and sprinkler systems within the membrane.The Owacoustic® programme contains products that have numerous appli-cations for many types of situations. A selection can be made from the follo-wing list.

1.3 Site conditions

The installation of an OWAcoustic® ceiling forms part of the interior dry finis-hing phase of construction.

The installation of an OWAcoustic® ceiling should, ideally, take place in a nor-mal environment (temperature range 10°C to 30°C and relative humidity bet-ween 30 - 70% r.h.). Wet trades such as plastering and screeding should becompleted and dry.The building should be weather tight with all windows glazed and exteriordoors in place.

It is recommended that installation should take place at a temperature closeto that which will prevail in the area during subsequent occupation.OWAcoustic® 15 and 20 mm thickness tiles can be used in conditions of upto 95% relative humidity (14 mm nominal up to 90%) at temperatures notexceeding 30ºC. In case of doubt over relative humidity or in known severeenvironments e.g. conditions that are outside normal limits (including ceilingsopen to the external atmosphere) we recommend the use of MAVROC® highhumidity tiles.

1.3.1 Relative Humidity

The relative humidity is always dependent on the temperature. A drop in tem-perature in an enclosed area causes an increase in the relative humidity.In new buildings, there should always be a free airflow available to ensure thatdamp air is evacuated from the area into the open air.

In a situation where the installed ceilings in a new building are in areas withnormal room temperatures at 20ºC and relative humidity at 70% and thetemperature at nights and weekends drops by 5ºC to 15ºC and assumingthat all doors and windows are closed. The calculation of the relative humi-dity in these areas can be calculated from Chart 1 using the followingmethod.

The reading of 12.10 is taken at the crossing point of 20ºC and 70% relativehumidity on Chart 1. This means that there is 12.10 g moisture / m3 air at20ºC / 70% r.h.

With a temperature drop of say 15ºC, the relative humidity increases. If youfollow the 15ºC temperature line to the closest value to the air saturation figu-re of 12.10g you find that the relative humidity has risen to approx. 95%. Insuch circumstances it requires that high humidity resistant panels such asOWAcoustic® "Mavroc” are used.

1.6 Reinforcing Spline No. 8040 / 8041

The reinforcing back spline is fixed to the reverse face at the centre of thepanel parallel to the long edge. A barbed clip No. 8041 is positioned in eachslot along the spline and is tapped through the slot into the board. The spli-ne can be used to support panels up to 1500 mm in length in an exposedor concealed suspension system. The exact length of the reinforcing splineNo. 8040 varies with the suspension system (see drawings).

Examples of spline length required for exposed and concealed systems:

Exposed Systems : S 3, S 3a, S 15, S 15aModule size 600 x 1200 mmPanel length = Module - 6 mm

= 1200 mm - 6 mm = 1194 mmSpline length = Panel length - 5 mm

= 1194 mm - 5 mm = 1189 mm

Concealed Systems : S 1, S 1aS 1 Module size 600 x 600 mmSpline length = Module - 25 mm = 575 mm

On site application of reinforcing splinesNo. 8040 Triangular flanged sections slotted at 150 mm centres fixed to cen-tre of panel in longest direction by means of clip No. 8041 tapped into boardthrough every slot in the spline to ensure maximum panel support.

Clips required = approx. 7 clips per linear metre of spline.

Technical data

2.1 DIN 18168 Part 1 / BS 8290 Part 1

These standards deal mainly with the code of practise and design criteria forsuspended ceilings.

2.2 Direct Fixed Ceilings

Direct fix ceilings are those which can be fixed to timber battens that aresecurely located onto the soffit by mechanical non-adjustable fixings.OWAcoustic System S 1 with direct fixing clamps is a directly fixed ceiling.

2.3 Suspended Ceilings

Are suspended or lowered ceiling systems by means of metal hanger suspen-sion with a static loading capability and which is adjustable and correspondsto the description in point 2.5.

2.4 It should be ensured that there are no transverse or torque forceswhich can be transferred onto the suspension system. To ensure that thisdoes not occur there are available wide span sections that can be used as aprimary suspension bearer. (See point 5.0) The maximum deflection of a cei-ling between the suspension points must not exceed 1/500 of the span (e.g.span > 1200 mm max. Deflection = 2.4 mm). Total maximum Span / deflec-tion allowed = 4.0 mm

2.5 DIN 18168 part 1 abbreviated

a) Range of applications - Suspended Ceilings with self loadings up to 0.5 kN/m2 ~ 50 kg/m2

b) Metal suspension components must have a certified static loading.Maximum deflection of metal sections should be no more than 1/500 of the span between supports (e.g. hanger distances) and not more than 4.0 mm in total

c) In the event of failure or loss of support the suspension system must not be subject to continuos collapse.

d) If partition walls are fixed to the ceiling the resulting lateral forces must be supported by additional structural components.

e) Suspended ceilings should be designed to accommodate structuralforces so that in the event of any non-ascertainable wind stress, no collapse of the membrane or any loosening of the suspension hangers occurs.

f) Sub-structures, which serve as free support must be secured against lateral movement

g) There must be at least one suspension hanger for every 1.5 m2 of ceiling membrane surface.

h) Only certified tested and approved fixings are to be used foranchoring the suspension hangers. Anchoring onto wooden laths set in concrete is not permitted.

i) Reference must be made to the appropriate DIN / BS standards forfire, insulation and soundproofing requirements.

j) Table 1 denotes the minimum material thickness of metal suspensionhangers (see Point 12.1).

k) Table 2 denotes the minimum requirements for protection against corrosion for metal structural components (see Point 4.0).

3.1 Building Material Classification DIN 4102Parts 1 and 2 / BS 476 parts 6 and 7(Reaction to Fire)

OWAcoustic® ceiling tiles and panels are manufactured from a base boardconsisting of high temperature resisting mineral wool fibres and natural bin-ders. Under DIN 4102 part 1 the board is classified as being either A2 -Incombustible with the test mark PA.111 4.143 or B1 Highly flame resistantwith the test mark PA.111 2.840.

Under British standard BS 476, part 7 all boards are classified as class 1 andunder BS 476, part 6 all boards are classified as class 0 in accordance withApproved Document B to the Building Regulations.

3.2 The appropriate prescribed test mark can be found on the packlabels and on the reverse of OWAcoustic® tiles and panels.

3.3 Fire Protection Classification F 30 ... F 120 –DIN 4102 Part 2 / BS 476 parts 20, 21 and 23(Resistance to Fire)

OWAcoustic® ceilings have been tested to the relevant DIN and BS stan-dards. The ceiling must be installed in accordance with the details shown inthe test documents. Any deviation from that shown on the test certificate canonly be made with the consent of the testing authority. The basis for mosttesting is generally based upon the regulations of the particular country.

3.4 The fire protection certification and expert assessments issuedagainst the results of many tests on OWAcoustic® ceilings represents officialdocumentation of compliance with DIN 4102 and BS 476. They contain fulldetails of the testing methods and results obtained. If any changes aremade in the construction of the ceiling, spans of sections or sizes of tiles,etc.., the onus of proof of compliance rests with the person who sanctionedthose changes.

3.5 Notice

The described fire-protection-notice and structural designs only take intoaccount the available technical basic facts for preventive fire protection asper DIN 4102, Part 2. Building physics or other require-ments, which canresult from appropriate norms, rules or other regulations,etc. are not takeninto account. They are in addition to be observed in the planning for fire pro-tection.

Corrosion ProtectionSections and SuspensionHangers

4.1 The moisture content of a room primarily affects the ceiling in-fillmaterial. A suspended ceiling does not however consist of only in-fill panels,but also of the suspension – structure. This consists principally of cold-rolledsteel sections, which must have a suitable corrision protection according tothe environmental conditions in which it is installed. An unequivocal perfor-mance standard can be found in DIN 18168 Part 1, in Table 2.

Table 2 – from DIN 18 168, Part 1:

4.2 The OWAconstruct® corrosion resistant suspension system has a zinclayer thickness of 7 to 10 µm + primer 7 µm and can therefor be allocated toline 1 of the aforementioned table. Only the OWA system S 3e with an addi-tional polyester coating of 20 µm meets the requirements of ASTM D 2247and other tests denoting suitability for use in swimming pool atmospherese.g. (Test Institute of thte University of Ghent)The use of system S 3e can be implemented for component parts from line 2of the table, subject to client consent. All cuts though the corrosion protectionmust be post-treated with Zink or other similar commercial aluminium-zincspray application.

Installation ofOWAcoustic® Ceilings underWarm and Cold Roofs

6.1 Used with single skin non ventilated Roof (Warm Roof)

OWAcoustic® ceilings provide good heat insulation and therefore can beused to control the dew point.

To avoid the formation of condensation it is recommended that a heat insu-lation / dew point calculation is made. In Part 3 of DIN 4108, it is noted thatthere are no negative influences by the sub-sequent building in of additionalheat insulation providing it does not involve more than 20% of the thermalresistance being on the warm side of the vapour barrier (thermal conductioncoefficient 0.063) otherwise ventilation of the roof space will be necessary.

6.2 Used with double skin ventilated roof(Cold Roof).

The structure of a double skin roof generally consists of :

a) Weather resisting outer skinb) Ventilated zonesc) Heat insulation zonesd) Airtight damp coursee) Suspended ceiling (fire proofing / sound proofing / hygiene etc.)

A ventilated or cold roof has an airflow zone in the roof space (between theoutside skin and the insulation layer) connected to the outside air. (See also DIN 4108 Parts 3 + 7 and BS 5250 : 1989 section 3)

6.3 The free airflow in these zones is mainly dependent on the pitch anddepth of thte roof. The air-out ventilation openings in the roof ridge area mustbe larger than the air-in ventilation openings on both sides of the eaves.

The exact ventilation area required, can be calculated or taken from DIN 4108Part 3 or BS 5250 section 2. Attention must also be paid to the diffusionequivalent thickness of the air layer sd. This is dependent on the roof pitchand rafter length and can be up to sd = 10 m.The provision of a vapour seal on the “warm side” of the structure is therefo-re necessary. Energy saving legislation requires that proof of airtightnessmust be given. To check the functionality of such a roof structure requires theadvice of a specialist in building physics.

6.4 In ventilated ceilings it is recommended that the heat insulation layerand the suspended ceiling membrane be seperated from each other so thatthe suspended ceiling can fulfil other functions such as fire protection, soundcontrol, support for light fittings and other installations and most importantly,appearance.For planning and installation recommendations, the basic rules of DIN V4108-7 and BS 5250 section 2 should be applied.

Principle of building physicsTechnical and other requirements related to building physics and fire protec-tion, flow from the relevant specifications. Thermal protection requirementsand other relevant legislated functional standards are not taken into account.They must be observed during the course of planning. The manufacturer ofthe suspended ceiling system assumes no responsibility in this connection.

7.1 Connecting and fixing elements

In order to make a frictional connection between the soffit (roof) and anOWAcoustic® suspended ceiling system, only tested and approved metalanchors and fastenings should be used (See DIN 18168 Part 1 and BS 8290: Part 2 : 1989).

7.2 Solid concrete soffits

The connection between the suspension hangers and a solid concrete sof-fit should only be made with tested and approved metal drill anchors. Themanufacturers instructions should be followed.

Testing figures for anchor fixing pull-outs should be noted and agreed with theMechanical Engineers to ensure the correct fixing requirements for the instal-lation.Suitable fixings are KKM-drill anchors No. 97, drill No. 98 or other approvedand tested metal drill anchors.

7.3 Fixing to roof steelwork

The suspension hangers are generally fastened onto the steel girders bymeans of caddy-clips.Suitable are:OWA-suspension clips No. 13OWA-flange clip No. 8013

7.4 Porous and light aggregate soffits

Approved metal inserts such as No. 97/9 should be used. Precise fixinginstructions and technical data should be requested from the manufacturers.

7.5 Profiled sheet roofs

If there is no alternative to a direct fastening of the hanger to the profiledsheeting, then only the vertical ridges are to be utilised. Tight screwing downof the fixing is necessary. The hanging of wire hooks into drill holes is not per-mitted.The main supporting sections of the suspended ceiling should run transver-se to the direction of the profiled sheeting in order to achieve a balanced loaddistribution.Suitable fixings are: Approved profiled sheet bolts or hollow rivets No. 97/14

Notes:Under unfavourable weather conditions the effect of wind pressure or suc-tion can cause oscillation of the roof which can be transferred through thesuspension components onto the ceiling.

This can cause gaps to open in the ceiling and structural noise may occur insome cases where the metal parts or panels rub against each other. Aremedy could be to make the ceiling independent from the roof by using aprimary wide spanning support between steelwork (See point 5.0)

7.6 Structural-borne noise and vibration –Isolating hangers

A non-interacting noise and vibration ceiling system is necessary in noisy orvibrationally intensive areas. Suitable in such situations are OWA isolatinghanger No. 8036 or isolating anchor No. 97/7.

7.6.1 In vibrationally intensive manufacturing areas and similar situations,it is recommended that only through bolted suspension hangers are used.Suitable are slotted suspension hangers which are tightly bolted through themain supporting section.Push on friction hangers are not suitable.

7.7 In situations where appliances such as refrigerators, freezers etc, cancreate excessive humidity levels, OWAcoustic® Mavroc panels arerecommended (see point 1. 5) or standard OWAcoustic® panels can beequipped with rear side reinforcements (see point 1.6). All panels must besecured in the corners with hold down clips No. 44/20 - 2 No. per panel side.

7.8 OWAcoustic® "Sanitas"- panels for hygienic areas.

In hospitals and areas where enhanced levels of hygiene are required the cei-ling should have good fungastatic and bacteriostatic properties on the expo-sed face.

OWAcoustic® Sanitas panels comply with DIN 4102 building material class A 2incombustible and are treated with an active anti-fungi and anti-bacterial sub-stance. By using a concealed grid suspension system, e.g. System 9 - Plainor 68/0 Cosmos without needling, the requirements for sterile areas aremet, see leaflet No. 848.

7.9 OWAlux – clean rooms

OWAlux standard and OWAlux 2000 provide an excellent smooth non-sporous and non-abrasive surface which is ideal for clean room areas and willcomply with Directive 2083 "Clean room technique”

a) OWAlux white painted aluminium foil without needling should be used

b) All OWAlux panels must be silicone sealed into grid and perimeters.

c) Design related junctions and joints with other sections must be sealed.

Note:In the case of ongoing wet cleaning or disinfection of ceilings, OWAcoustic®

OWAlux surface design white 64/08 without surface needling isrecommended.

7.10 Building expansion and movement joints

In principle, these are to be provided when covering planning soffits and sus-pended ceilings.

Note:For ventilation options of suspended ceilings, see point 13.7

Climate Control Ceilings

8.1 If the ceiling cavity is to be used as a pressurised plenum and the airinput and extraction is made via openings (air vents) in the ceiling then thefollowing procedures must be observed, for example in a System S 3 instal-lation.

a) All panels must be sealed permanently into the grid by elasticatedfoam sealing strips applied to the flanges of the T-sections and the perimeter trims and any fittings etc..

b) The air speed must not exceed 1.5 m/sec.

c) The relative humidity in the ceiling void and the area below the ceiling must conform to the humidity limitations of OWAcoustic panels dependant on design and size (see points 1.4 to 1.6).

d) Owacoustic panels laid into exposed grid systems must be fitted with hold down clips No. 44 or No. 44/20 - at the rate of 6 no. per m2.

e) The upper and lower pressures in the ceiling void should not exceed 15 Pa, (Approx. 1.5 kp/m2).

9.0 OWAcoustic® Mineral Wool Panels

The nature of the ingredients of mineral wool tiles dictates that the surfacemay show slight surface striations (scratches) caused by the surface sandingprocess. These small imperfections are unavoidable and are, to a certainlevel, considered tolerable. The paint surface may show some shade variation between different pro-duction batches.

OWAcoustic® ceiling tiles can be supplied, with a few exceptions, in BuildingMaterial Class A2 - Incombustible and B1 - High Fire Resistance - as per DIN4102 and relevant BS 476 part 6 and 7. (See product range)These materials will withstand short term exposure to humidity levels up to ≤95% r.h. (See point 1.4)

OWAcoustic® MAVROC panels which can withstand levels ≤ 95% permanentr.h. can be supplied in Building Material Class B1 only. (See point 1.5)

OWAcoustic SANITAS tiles are only supplied in Building Material Class A 2non-combustible and will tolerate short term exposure up to ≤ 95% r.h. (Seepoint 1.4)

9.1 Loading on OWAcoustic® tiles

Normally OWAcoustic® tiles should not be subjected to additional loadingother than lightweight mineral wool overlays with a bulk density maximum of200 N/m3 and a thickness of 50 mm (10 N. m2). In cases when it is necessary to exceed these loading levels there are speci-al procedures to be followed (e.g. supporting the overlay on wires across thegrid system or the use of reinforcing metal splines on the back of the tiles.See point 1.6).

Example:Supporting excess loading of sound insulating overlay materials.

Alternatively the hanger centres can be reduced or a supporting sub-sus-pension could be installed to carry the sound insulation mat.

9.2 Cutting and working OWAcoustic® mineral tiles

OWAcoustic® tiles can be cleanly cut with an OWA or other retractable bladedknife.

9.3 Direction arrow

On the reverse of every OWAcoustic tile there is a machine run dotted direc-tion arrow. Care should be taken that the tiles are installed with the directionarrows pointing the same way. (Except when laying the tiles in a chequerbo-ard pattern.)

9.4 Packaging and handling of cartons

Do not drop, roll or place cartons on their edges. Store flat on an even sur-face in a dry location. The tiles are packed face to face.

When removing tiles from the packaging always take two tiles face toface. The packaging should always be cut open to avoid damaging thetiles during removal.

Always handle tiles with both hands during installation.

Mixing of tiles from different production batches should be avoided asthis can lead to paint shade variations in the ceiling.The production date code is printed on the outside of each carton anda date stamped on the reverse of each tile as well as the Building classreference . (See points 3.1 and 3.2)

Storage and handling instructions for OWAcoustic tiles are enclosed witheach packaging unit.

9.6 Border or cut size tiles

The perimeter trim panels will be dependent on the size of the room. Oftenarchitectural aspects of the layout will dictate that the division of the perime-ter tiles are in an unfavourable ratio to the field tiles. This can also result fromspecial size luminaires / grilles etc..If the above mentioned points do not apply, then it is recommended that theperimeter or border tiles are installed using the following procedures.

The perimeter tiles should be of equal size if possible on both opposing sides ofthe room and always larger than half a tile.

For example, in a room with a width of 2.5 m and when using tiles size 600x 600 mm the layout example results.

In the recommended layout method, there are three full tiles and two cut tothe perimeter, rather than four tiles with one cut to the perimeters. Whilst thenumber of tiles used in each case is the same the recommended method isaesthetically more pleasing as well as being more economical. (see exam-ple.)

9.7 The effect of lighting or luminaires onsuspended ceilings

For visual reasons direct light onto concealed suspended ceilings should beavoided. This also applies to glazed facades where the glazing extends tothe lower edge of the suspended ceiling. In such cases an uneven lippingeffect can appear at the tile joints due to the shadow effect of the direct light.

Pre-installation planning

10.1 Site inspection to ascertain area location, proportions and to checkmeasurements, etc, is an essential requirement. The layout design and arran-gement of luminaires, fixtures, etc, should be established with the architect.

10.2 Fire protection as per DIN 4102 / BS 476

If the OWAcoustic® ceiling has to meet fire protection requirements in accor-dance with such standards as DIN 4102 or BS 476, then the ceiling must onlybe installed in accordance with the details contained in the relevant test cer-tificates. Divergence from these details must be avoided (See also point 3).Suspension head fixings may only be carried out with approved and testedfire compliant metal anchors.

10.3 Light weight suspendend ceilingsaccording to DIN 18168

If correctly installed, OWAcoustic® ceilings correspond to DIN 18168.(See point 2.0)

OWAcoustic® Metal suspension systems

11.1 Basic Systems

There are detailed system leaflets available for all OWAconstruct® metal sus-pension systems.Technical data, spans, loadings, etc, are shown in these leaflets.

Prior to the planning and installation of an OWAcoustic® ceiling, it mustbe ensured that the leaflet in question is up-to-date and correspondswith the latest technical developments.

11.2 Ceiling Loading – additional loading

The concept of OWAcoustic® ceilings is that the load of the ceiling tiles, inclu-ding the suspension system, is taken within the safety loading of the con-struction. Additional loads, such as integral and built on luminaires, airhandling vents, grilles, insulation overlays, curtain rails, partition walls,etc..must be in every case independently suspended or supported by means ofstrengthening of the supporting structure. Furthermore, care must be takento ensure that additional loadings are not imposed on the suspension grid(such as electric / service trays and cables etc.) (See point 9.1)

11.3 Installation in rooms ventilated by swivellingor tilting windows or skylights

When installing OWAcoustic® ceiling tiles, care should be taken to ensure thatthe perimeter tiles, especially when subject to apparent wind pressure orsuction, chiefly in the vicinity of the windows, are firmly clipped into place.The exposed grid systems should be secured with No. 44 or 44/20 holddown clips.

Suspension Hangers

12.1 Suspension hangers make the connection between the soffit (roofdeck, steelwork, etc) and the suspended ceiling. Under DIN 18168 thesestatic bearing components have a permitted load force in 3 load bearingcapacity classes. Verification is either by calculation or reference to certificati-on by a recognised testing authority. As a fundamental principle, suspension hangers should be set vertically.

Offset or angled suspension are only to be utilised in exceptional circum-stances. Wire suspension hangers should be secured in such a way thatsubsequent unhooking is not possible.

12.2 Load bearing capacity classes:

Permitted F = 0,15 kNPermitted F = 0,25 kNPermitted F = 0,40 kN

The minimum material thickness of the different materials for suspensionhangers are set out in table 4 of DIN 18168.

Perimeter trims

13.1 The fixing of the perimeter angle trim constitutes the first operation ofa suspended ceiling installation.

A coloured chalk line should be struck along the outer perimeter wall at therequired level. It is advisable to put the chalk line at the level of the top flan-ge of the wall angle trim to eliminate the need for cleaning pre-decorated wallsurfaces

Example:

The perimeter trim wall fixings should be at approx. 300 mm centresdepending on the load.

For fire protection ceilings the fixings should be a maximum of 250 mmcentres

Steel nails, impact dowels or steel anchors are suitable perimeter trim fixingsdependant in each case on the fixing background material.

13.2 Internal and external mitres should be cut true or, alternatively, speci-al cover strips (OWA No. 54, 54/50) can be used.Unevenness in the walls should be filled and painted. Alternatively a timbershadow batten can be used.The written specification should clearly establish the rules.All reinforcing sections and tiles must overlap the perimeter trim by ≥ 2/3 ofthe flange width.

Example: Section and tile overlap on perimeter trim. (See illustration)

When perimeter trims are fixed to timber, wood based materials, exposedconcrete or other potential shrinking backgrounds, the fixing points mustallow for background movement without distortion of the perimeter trimoccurring. i.e. by using pre-slotted wall trim.

Fixing alternativesa) Use perimeter trims No. 51/20 or 53 with elongated slotted holes.b) Use Main tee section No. 45 on sliding hangers.

Butt-jointed trims are current practice. Mitres should be used in situations ofstep wall details.

If the unevenness of the walls is in excess of the tolerances in DIN 18202 orBS 8290 and necessitate filling and smoothing this should be considered anextra cost.

13.3 Cutting mitres on stepped shadow wall trimusing “tin snip” shears

Cutting procedure:The desired mitre cut should be drawn on the upper side of the section. Thepencil lines dimensioned as shown in the drawings A and B (see table).Using right hand shears the 45° and vertical cut is made starting from point I.Using left hand shears the 45° cut is made starting from point II.The cut stepped wall section is fixed to the wall. The abutting section is laidon the cut mitre, its outline drawn, cut out and fixed.

It is however simpler to make mitre cuts using a circular metal saw – see illu-stration. These saws are available with suitable attachments for all sectioncuts.

Concealed metal suspension for systems S 1, S 1a, S 9

14.1 The above concealed systems have a common metal suspension gridcomprising the following components.

Head fixingsOnly approved metal anchors (no plastic) or types recognised as testedshould be utilised, see point 7.0....7..6.1 or DIN 18168

Suspension hangersSuspension hangers should be selected in accordance with the type of sus-pension point available (see point 12). The maximum permitted load forcemust not be exceeded. The spacing between each hanger should be set inaccordance with the maximum permitted load and the load carrying capaci-ty of the metal section based on DIN 18168 - a minimum of one suspensi-on hanger must be installed for every 1.5 m2 of ceiling area (see point 2.5).Maximum suspension hanger centres 1200 mm and no more than 450mm from any perimeter wall.In the area of section couplings the hanger centres should be closed up (seepoint 2.5).

Additional loadingsSee points 11.2 and 9.1

Perimeter trimsSee point 13.0

Fire protection as per DIN 4102See points 3.0, 3.5 and 10.2.

Main suspension section No.70The main section No. 70 should be installed parallel straight and level atmaximum centres of 1200 mm and no more than 450 mm from any peri-meter wall.Section No. 70 is supplied in mill lengths of 3, 5 and 6 metres.

The individual tiles in these systems are non - demountable.There are however fixed access traps available which are described in moredetail in points 18.0, 19.0, and 20.0.

Z- Sections galvanised No. 20 or black painted No.58The Z-sections support the OWAcoustic® tiles which are slotted onto theflanges of the Z-sections which are fixed at right angles to the primary sec-tion No.70.The Z-sections are normally supplied in 3.0 m lengths, they are joined byconnector No. 25. The connectors should be staggered.

Fire protectionAt the point of connection the Z-sections should not be butted together. Anallowance for expansion of approx. 10 to 15 mm should be made.

Wire Z- clip No. 60The Z-sections are secured to the primary section No. 70 with wire clip No.60. The maximum load on this 3.0 mm diameter clip is 7.5 kp.

No. 60

T-section No. 23, Spline No. 27, L-Section No. 24The cross joints of OWAcoustic® ceiling tiles must be reinforced with metalsections. Splines can be used up to 300 mm and T-sections from 400 mmupwards. Demountable tiles are reinforced with L-sections.

Wall spring clip No. 52Wall spring clips are used at the perimeter to provide the compression requi-red to prevent the joints on the border tile opening.

Wall springs are only to be used on the cut sides of the tiles that abut theperimeter wall angle.With tiles up to 300 mm wide use I clip per tile. When using 600 mm widetiles 2 clips per panel are required.

Note:To ensure alignment of the joints the first row of tiles in a concealed systemmust be installed extremely accurately.

The alignment should be adjusted to an accurately positioned "string line”.

Each individual panel must be accurately scribed into the perimeter wall withno margin for error.

A wall spring is inserted at the ends of each row of OWAcoustic® tiles andon every tile at the perimeter. For fitting of the "final tile” see point 17.

Fixing the last tile

The fixing of the final tile is carried out as follows:When the penultimate tile is in position the measurement of the final tile isacurately taken in the corner (See Fig.A).

The final corner tile is cut approx. 10 mm shorter (See Fig.B)The penultimate tile is removed and the final tile is put in place and the wallspring clips pushed as flat as possible (See Fig.B).

By doing this sufficient room is made for the penultimate tile to be replacedin position (See Fig.C).The penultimate tile is therefore the last tile to be fixed.The unsupported edges are reinforced with L-sections No. 24

Concealed access traps andretro-fitting replacement tiles

In a concealed grid system it is often required that a tile be taken out or adamaged one replaced. With system S 1 it is possible to provide access at pre-determined points(See Figs.1....5).This method is designed to give a 600 x 600 mm opening.The OWAcoustic® tile is removed at the designated position (Fig.1.) The reinforcing T-sections No. 23 are removed and replaced with L-sectionsNo. 24.A new tile is prepared for insertion using the following method. Care shouldbe taken to maintain the existing installation layout e.g. fissured che-querboard design.

On the replacement tile (Fig.2a) the rear surface edge that runs parallel to theZ-section is cut away to the depth of the kerf, creating a deep rebate (Fig.2b).It is then necessary to re-cut the kerf, using a hand saw, to accommodatethe L-section (Fig.2c). L-section No. 24 is then pushed into the newly cut kerf(Fig.2d)

2 No. 32 L-sections cut 40 mm shorter than the module ( i.e. 560 mm for 600x 600 module) are then inserted into the cross kerfed edges to provide thelocking mechanism as per figs. 3 and 4.

The prepared unit is then fitted into the ceiling and locked into position by sli-ding the tab so that the opposite end of the L-section is pushed over the tableof the Z-section as per fig. 5.

The reverse procedure is used to de-mount the tile by pulling the tabs torelease the tile from the grid.

Material required for one access / replacement unit is:3 x L-section No. 242 x L-section No. 321 x OWAcoustic® ceiling tile.

The tile or panel selected must be undercut and bevelled (see illustration). Theedges at right angles to the Z-section have L-sections inserted in the kerfsinstead of T-sections. When forming an access into linear planks it may benecessary to re-cut the kerfs into the short edges.

The tiles / planks are prepared and repainted on site.

The access tile / plank is removed by lifting the rebated edge and lifting it clearfrom the Z-section.

Retro-Fitted steel access frameNo. 8033 for concealed system S 1

Installation:

1) The selected tile in an existing ceiling is cut or broken out from the grid.

2) The T-sections No. 23 are removed from the adjacent tiles and replacedwith L-sections No. 24.

3) Ensure that the replacement tile is following the direction of the surfacepattern e.g. fissured chequerboard layout.

4) On one edge which runs parallel to the Z-section, cut away the backedge to the depth of the kerf to form a rebate.

5) Cut a new kerf in the rebated edge with a hand saw.

6) The edge in the area of the locking tabs must be cut back to allow freesliding of the tabs (see B).

7) Push the metal frame onto the prepared tile (see A).

8) Insert the unworked edge of the tile into the Z-section and close the reba-ted edge onto the opposite Z-section and lock into place by sliding thetabs forward (see C).

Weight: 2.0 kg

This heavy duty steel trap door is designed for use in ceilings where regularaccess is required at pre-determined points.The unit has been designed for use with OWAcoustic® mineral wool tiles andis manufactured from galvanised steel to withstand frequent use withoutdamage.It is suitable for use with OWAcoustic® concealed systems S1 and S9 as wellas exposed grid systems S3 and S15. All exposed parts are white painted.

The advantage of this access trap is that it can be built in with the same sur-face on the door as the rest of the ceiling. When closed only the white framesurround is visible.

Installation

The same principles for support as for luminaires apply. The access trapshould have independent suspension hangers on each of the four corners.The suspension points are located on the access trap framing.After hangers are installed the frame is p.k screwed onto the table of the Z-sections.

When installing in an exposed grid system independent suspension of theaccess trap on all four corners is still necessary.

A locking key is supplied with each access trap No. 8032.

Fire protectionWhere fire protection is to be maintained a fire box must be built over theaccess trap (see Point 26.3).

The loading of the grid is as per point 14.0

The S 9 system is a unique concealed system in that it allows each individu-al panel to be removed and replaced. It is recommended that removal ofdemountable ceiling tiles is carried out by a qualified ceiling fixer.

22.1 Stepped Z-section No. 63

The design of this section allows for a concealed ceiling tile to be removedwithin the space between the Z-sections. The sections are clipped onto theprimary carrier with two wire clips No. 60. The Z-section No. 63 should befully aligned before the clips are secured.

The OWAcoustic® concealed demountable tiles have two shiplapped edges(Edge 4) and two BKR (Edge 1) - see point 9.5.

During installation care should be taken that the tiles are installed in a "loosebond” to facilitate removal and replacement at a later date.

The two BKR edges are supported by L-section No. 24

The quality of the appearance of the finished ceiling will be dependant on theaccuracy of the installation of the first row of tiles. The tiles in this row, as forthe rest of the ceiling, must not be pushed tight together.

Small repairs can be effected with OWA repair kitsNo. 99723 for standard paint finishNo. 99724 for Cosmos paint finish

22.2 Perimeter trims - See Point 13.0

The standard perimeter trim section is No. 50 (25 x 20 x 0.6 mm). The peri-meter tiles are fixed without wall spring clips. The tiles should be cut to theperimeter wall with a gap of ≥ 1.0 mm.

22.3 OWAcoustic® ceiling system S 9Direct fixing with clamp No. 62

Where there is a restriction on suspension height the Z-section No. 63 canbe fixed using 2 no. 62 metal clamps screwed to a timber batten. See Point16.0

Perimeter trim No. 50 (Contura)

Hand rebating the contura tiles onto the trim with Contura tool No. 99/11 isa costlier option but produces a neater wall perimeter detail.

To form a rebate on the border tile each one must be cut and fitted into thegrid.

The tile is then marked on the face with a pencil line which must be more than9 mm from the square cut edge. The tile is then cut 9 mm from the line withOWA bladed knife No. 99/01.

The rebate on the edge is then formed using Contura cutting tool No. 99/11.The bevel formed in this process must be whitened using OWA chalk.

Loading Principle

Attention:The combination of C-, L- and Z-sections can cause different deflec-tions because of the different elastic-modulus, although the maximumdeflection according to DIN 18168has not exceeded.

System 18 - Parallel Pan Grid (Bandraster)

The parallel pan grid system S 18 suits situations where the flexibility of re-locatable partitions are required to provide variable work space areas in, forexample, administration buildings, schools, hospitals and many other publicand commercal buildings. The intervals of the pan grid sections can be adap-ted within the existing building modules.

Lighting is designed on an optimum basis and can be easily integrated intothe system as well as air-conditioning outlets and information technologywork stations.

The pan grid sections can be used for locating partition walls and will provi-de a great deal of scope to suit individual plans for adapting usable space.

26. 2 Vernier suspension Hanger:

The suspension hanger consists of a lower part which forms the connectionto the ceiling suspension sections and an upper part which transmits the cei-ling load to the structural soffit, roof or primary supporting construction e.g.a wide spanning carrier section.

The adjustable connection between the upper and lower parts of the hangeris via a safety split pin No. 76 or a connecting nail No. 78 which is bent overafter levelling.

When using a safety split pin or a connection nail a static tensile load up to amaximum of 0.25 kN (25 kp) is permitted.

For dynamic suspension load (tension and pressure) two safety split pins orconnection nails are required on each hanger. Load erosion also depends onthe length of the suspension hanger.(See table 26.3)

The number of suspension points is governed on the one hand by DIN 18168T 1 and on the other hand by the maximum permitted suspension load andthe pan grid carrying capacity.

OWA-Terra (standard lighting) and UWA-Opta (BAP supported)(See leaflet No. 631)

Light fittings are available for various applications and are supplied to fit stan-dard modular Pan grid (Bandraster) ceilings, see point 26.4, or as specials upto 2400 mm in length. Fixing is by integralsuspension brackets fitted to thefront of the fittings which locate directly onto the Pan grid (Bandraster)sections. The diffuser panels are laid directly onto the grid.

The lamp widths are 300 mm or 312.5 mm. Lengths up to ≤ 2400 mm areavailable.

When using light fittings in excess of 1600 mm in length additional hangersshould be located in the area of the fitting.

Lamp lengths of ≥ 1600 to ≤ 2400 mm are normally suspended from their cen-tre. Fixing brackets are available on the body of the light fitting.

In the case of fire protecting category F 30 – F 90, the principles of therecommendations in point 27.2 should be observed.

Integrated light fittings

Wiring and installation of light fittings is generally the task of an electrical con-tractor but it is, however acceptable for the ceiling contractor to position lightfittings into the grid system.

Important principles:No electric cables can be fixed to the suspension system.

The cabling of electrical leads into or onto the grid suspension system shouldbe avoided.

Single cables, which provide connection direct to the light fittings can beattached to the hangers by agreement with the ceiling contractor

Applicable VDE regulations must be observed.

27.1 Any additional load, which is transmitted to the ceiling suspensionsystem must be independently suspended. There are various options fordoing this.

It is important not to overload the suspension system or the hangers.

a) To suspend the fitting directly

or

b) To ensure that the ceiling grid structure is fitted with additional suspensi-on hangers. The total additional loading must be evaluated in terms of pos-sible section overloading.

c) A further method is to install an independent supporting structure with C-sections or fire treated timber batten.

d) When installing recessed luminaires it is advisable to install a supportingstructure similar to that under point c)

e) To secure the luminaires by threaded support brackets attached to theexposed T-sections as per systems S3, S3a and S15, and S15a, it isimportant that the a hanger is positioned below the threaded bracketsupport. (See points 23.7, 23.4 and leaflet No.885)

27.1.1 Downlights, Speakers and other inbuilt items

Downlights weighing ≤ 2.5 N can be fixed directly on the OWAcoustic® cei-ling panels.

For loads up to 35 N per item support frames or yokes must be used, itemNo. 8069 see leaflet 605. The load distribution in the ceiling structure / sus-pension must be tested. (See also point 12)The build-in options take only symmetrical loads into account.

Asymmetrical and higher loads must be suspended directly from the struc-tural soffit.

27.1.2 Built-in light fittings and Downlights

27.2 Fire protection of recessed luminaires

In order to maintain the fire protection of an OWAcoustic® ceiling in the areaof recessed light fittings, it is necessary to implement the following protec-tive measures:-

a) Install additional suspension hangers. (See note under point 26.1)

b) Encase the luminaire in a ventilated fire proof enclosure using mineral wool Minowa panels.

Sizes of Minowa mineral wool panels:Length: 2500 mmWidth: 1250 mmThickness: Approx. 15 or 20 mm Building material class: A2 non-combustible oder B1 high fire resistance

27.3 Closed fire boxes

Suitable for luminaires with open louvres that allows the heat build up of theluminaire to escape downwards.

A fire box will also maintain the sound insulating qualities of the ceiling.

The installation of closed or ventilated fire protection enclosures should beagreed with the electrical engineer.

InstallationThe size of the fireproof enclosures will be dictated by the size of the lumi-naires. In general the enclosure should be 30 - 50 mm larger than the fitting.The Minowa panels are cut to size and secured together with nails (nailsapprox. 50 mm long at 100 mm centres).

Assembly of fire boxes for built-in units should be in compliance with therelevant test certificate.

27.4 Back-ventilated fire boxes

The installation of back-ventilated fire boxes is required when the heat buildup is channelled through the back of the light fitting and there is no require-ment for maintaining the sound insulation.

InstallationLow-melt rigid foam strips (e.g. styrene) approx. 20 x 20 mm x body widthare laid on the body of the light fitting.

A framing of mineral wool panels to suit luminaire size is fixed around the 4sides approx. 10 mm lower than the top of the rigid foam strips. A Minowacover board, overlapping the sides by 50 mm all round, is placed onto therigid foam strips.

In the event of fire the rigid foam strips will melt and the Minowa cover panelwill settle onto the Minowa framework surround and prevent the penetrationof fire into the ceiling void.

Test Cert. No. 781498 Test Cert. No. 2306381 78Data sheet No. 503 A Data sheet No. 535


27.5 Cable leads

If the holes drilled into the fire box are no larger than the diameter of thecable the fire rating of the box will be unaffected.

28.1 General

OWA ceilings consist of OWAcoustic® mineral wool tiles and metal sections.The tile surface and exposed surfaces of the metal sections are suppliedwhite painted.

OWAcoustic® ceilings can be re-decorated in a simple operation using stan-dard emulsion paint and working tools. The decorator should adhere to thefollowing instructions:

28.2 Humidity

The tiles must not become too damp as in this condition they may deflectfrom the level plane (bow). Care should be taken to apply no more paint thannecessary (See also point 1.4) !

28.3 Cleaning

Dirt stained or dusty ceilings should be cleaned down before re- painting.This will not be necessary when painting new ceilings.

28.4 Priming

The tiles, whether old or new, will require a priming coat to seal the surfaceto prevent the colour fading and the tiles from taking up too much moisture.A PVA adhesive such as Uni-bond mixed in a ratio as per manufacturersinstructions will be suitable. The sealer coat should be allowed to dry, depen-ding on humidity levels, for 12 - 24 hours.

28.5 Equipment

For application of priming and paint coats it is recommended that short hairmohair rollers - not lambs wool - should be used. This is because the paintshould not be thickly applied which would fill the small needle perforationsand degrade the acoustic properties of the tile surface.

28.6 Painting

After the priming coat has dried the finish colour may be applied. Depending on the colour tone more than one coatmay be required.It is recommended that the bevel edges are pre painted with a brush.

28.7 Spraying apparatus

If the paint is to be sprayed on Air-less procedures should be observed.Several coats will be required.

28.8 Colours

For renovation or production of coloured OWAcoustic® panels a dispersed pigment paint with acrylic or polyvinyl aceta-te binders is recommended

Exposed grid system S 3 or S 15Renovation recommendation for panels and sections parts:

Small colour damage can be treated with OWA touch up paint, see supply range

For standard matt white panel surfaces No. 99723For white Cosmos surfaces No. 99724

AcousticsSome OWAcoustic® panels have surface needling for acoustical reasons. The needling must remain open even after re-decoration as the closing these holes will reduce the absorption values by 30 to 40 %.

28.9 Water, oil, grease or rust spots must be treated before painting. The application guidelines by Caparol listed in thetable below are recommended.

1. Light applications:IsoDeck rapid paint. Specially suitable for sensitiveareas where it is necessary to work rapidly. Odourfree and environmentally-friendly.

2. Medium applications:Standard universal painting. Gloss, matt, structuredor entirely solvent-free and emission-freeELF coatings.

3. Specialized painting:Primer undercoat + Indeko-W or Malerit-WA special system with a fungicidal top-coatingspecially suitable for foodstuff processing and prepa-ration, also damp room operations (Indeko-W) aswell as kitchens and bathrooms (Malerit-W).

4. Difficult painting:Filter primer Isodek-WAn aqueous environmentally friendly paint system,particularly suitable for canteens.Iso-Deck is solvent and odour-free.

5. Extreme painting requirements:Dupa-inn or Dupa-mattA proven solvent based rapid redecoration paint foruse where other products fail. Particularly suitable forareas which must be re-occupied rapidly.
