Today’s drive for economic

efficiency demands flexibility

and ‘multi-tasking’.

Movable walls provide the key to

competent management of your

space and Alco Beldan has the

expertise to provide the

opportunity for you to make the

very best use of the space

available.

NW 100 WALL PANELS ACHIEVE AN ACOUSTIC RATING OF RW 58DB

whilst maintaining a panel thickness of 100mm

Alco Beldan has emerged as the country’s leading supplier of

acoustic movable walls. After many years working in this highly

specialised trade, we have built up an admirable reputation for quality

with both Architects and their clients.

QUALITY BY DESIGN.

Each component is designed to do its job precisely, with no expense

spared on research and development. The product has been

designed to give the best performance through years of effective

service, day in, day out.

QUALITY IN MANUFACTURE.

Our European factory has achieved ISO 9001 accreditation. The

panels are built on a dedicated production line, utilising modern

machinery and are delivered, fully assembled, direct from either our

factory in the Midlands or from one of our other facilities in Europe.

QUALITY OF OPERATION.

Drawing on the wealth of design experience gained by our technical

staff, our schemes are both innovative and cost effective. We also offer

on-site staff training after installation, because we understand that

ordinary people use the panels every day, long after the ‘experts’ have

left the scene.

Most projects begin with the spark of an idea, whether originated by

the need for more usable space in an existing building or the desire to

provide for greater range of activities in a new development. Each

project then becomes a challenge which calls for comprehensive

analysis in order to achieve its own individual solution.

Alco Beldan’s nation-wide team of technical advisors understand the

demands of integrating a movable wall system. Early and careful

consultation can solve many of the problems encountered whilst taking

a project from concept to completion. By working alongside Architects

and clients, offering our advice and expertise where the opportunity

presents itself, we seek to optimise the space available, and create a

visually impressive environment within the budget constraints, whilst

maintaining the overall programme schedules.

THERE ARE GOOD REASONS WHY:

Space ManagementTotal Flexibility

Space Management

By using advanced design technology and selecting the best materials

available means we don’t need different models to achieve higher

performance. Even the heaviest panels can be moved easily through

track junctions allowing full mobility of the panels and flexibility of wall

layouts.

The Alco Beldan NW100 Movable Wall is a true workhorse, although

finished differently, the same panel unit can be found performing its

sound reducing function every day in Offices, Hospitals, Schools and

Colleges, Community Centres, and of course, Hotels.

Whatever the application, the basic requirements are the same; for a

well-engineered, totally reliable movable wall system which will perform

well over its whole lifetime.

The Alco Beldan NW100 Movable wall does just that.

• Its not luck nor by coincidence that probably the most well known

hotel chain has installed Alco Beldan NW 100 movable walls in over

50 of their hotels.

They have demonstrated their confidence in our movable walls,

how about you?

• Ask yourself how can Alco Beldan reliably deliver and install

approximately 100 movable wall panels each working week?

Repeat business from hundreds of satisfied customers makes

up 75% of our order book.

• Acknowledged as world leaders in movable wall technology, our

German designed panels are now being developed and built here in

the UK.

Why don’t you take advantage of the best of both worlds,

the best quality at a competitive price?

• Alco Beldan are recognised in the Interiors industry for Gold Award

winning installations, and we have the confidence gained only from

years of experience in handling all types of project from the exotic,

with hung silk screen panels to robust and rugged panels installed in

schools etc.

From Church Halls to Sports Halls and Community Centres to

Convention Centres, our wall does them all. Thousands of users

have benefited from carefully thought out solutions using the same

basic product. As the name suggests, the NW100 panels are always

100mm thick, no matter what the application or acoustic rating.

Architect: Triad Architects, London

Internationally recognised as one of the most ornate buildings of the

world, the Swaminarayan Hindu Temple, in North London has used

Alco Beldan NW 100 movable walls to acoustically divide the Prayer

Hall.

The Prayer Hall is the central part of this complex, but because the

complete floor area of 2,300 m2is used only a few times each year, the

Hall needed to be divided into smaller, more manageable and efficient

areas for everyday use. Alco Beldan were asked to design a system

that would divide the Hall into three separate rooms, yet still be

manually moved into place by the resident staff.

The impressive proportions of the 51 x 45 metres of Hall floor area is

balanced by the 7.20 metres height and this meant there were two

important aspects to consider; the weight of the panels and ease of

their operation.

Each of the panels is carried on two specially developed rollers running

in heavy duty steel tracks fabricated to form semi-automatic stacking

bays at the end of each of the three movable walls used to divide the

Hall. The staff only have to roll the panels into the 45° track junction

and the panel turns easily into the stacking position. Although the

panels are just 100mm thick, their acoustic rating is R’w 51dB, and this

is enhanced by the addition of a special herringbone pattern acoustic

wallcovering applied by the main contractor.

The client is delighted with the performance of the panels and in

particular, the ease with which these panels, some of the tallest in the

country, are moved into place.

Architect: Goff Associates

There cannot be many in the independent hotel sector that haven’t

heard of the rebuilding of the Celtic Manor Hotel. Travellers along

the M4 corridor at this gateway into Wales cannot miss this magnificent

hotel which sits in an imposing position high on a hill overlooking the

motorway.

As expected of one of ‘The Leading Hotels of the World’ the interior

facilities are no less impressive with a carved Welsh Dragon dominating

the foyer, leading to 400 rooms and superb restaurants all serving an

international standard Convention Hall, the Caernarfon Suite. Alco

Beldan NW 100 movable walls have been installed in the convention

hall and the syndicate rooms but the most difficult challenge facing the

technical staff was how to support the 6.30 metre high panels in the

Caernarfon Suite. Above the ceiling is a 5.00 metre deep void to the

substantial roof structure, which also supports the car park. In order for

the heavy panels to operate in all conditions we had to take account of

100mm dead-load deflection in the roof structure which could deflect

a further 50mm under live load from the car park. The key to this

successful solution was our standard rapid action scissor link

mechanism, which provides more than 50mm of spring assisted travel

to our unique, double depth top and bottom seal carriers, specially

developed for this job.

Each panel is suspended on two rollers running in heavy duty track and

both roller hangers are fitted with self-locking height adjustment

devices which prevent the panels losing level alignment.

The track layout provides options to divide the Suite into six, with

doubled up tracks at the centre so two walls may be set up in a duplex

configuration for very high acoustic separation between the two areas.

The resulting acoustic performance from a duplex set of Rw 58dB

rated panels was assessed as Rw 65dB or better.

The panels are finished to match the panelled effect of the perimeter

walls so when closed, they fully integrate with the high quality décor,

and when not in use the movable wall panels are concealed in

recesses around the Hall.

To complement the colours used in the traditional Celtic design on the

ceiling, the panels were faced with burr poplar veneer with contrasting

inlays and American cherry mouldings for skirting and dado rails,

complete with bronze colour coded edge profiles.

Floor plan of The Caernarfon Suite at The Celtic Manor Resort

This conference centre won theaward for the most effectivefunctional design in theEuropean Hotel design anddevelopment awards 2000.

The project is interesting because it is on the site of the George

Bernard Shaw Theatre, part of which has been incorporated into

the scheme. The movable wall in the main function area is 4300mm

high and has a sound reduction rating of Rw 53dB. The panel finish

on our walls complement and match the structural walls around the

rest of the room. Movable walls are also installed in the reception

breakout area leading into the main function room and incorporate 2

sets of double pass doors. Additionally, operable walls have been

installed in the syndicate rooms with a sound reduction of Rw 50dB.

The Nicholas Grimshaw designed new stand at Lords Cricket

Ground has a number of private boxes divided by Alco Beldan

100 Series Movable Walls.

Acoustically these walls had to be manufactured to the highest

standard (58dB) to maintain privacy.

The success of the installation has created flexibility for Lords to also

lease out the enlarged boxes as meeting rooms to companies. This

again creates a multiuse stand that does not stand empty when there

is no cricket.

Alco Beldan have also installed movable walls in the offices of the

English Cricket Board, which is also within Lords grounds.

GENERAL DESCRIPTIONThe Alco Beldan NW 100 is a rapid actionmovable wall system designed for easy,efficient and reliable daily use. Interlocking,individual panels, 100mm thick, carried onrollers running in a top track only, pushtogether with an expanding panel as thelast element, to form a complete, securepartition wall. Panels have independentlyoperating pressure seal carriers extendingat top and bottom.

PANEL SIZESPanels are custom made with widths fromapprox. 650mm up to a maximum of1260mm. Panel heights from 2.00m up to10.00m approx.

STANDARD PANEL

CONSTRUCTIONEach panel is constructed with a weldedtubular steel inner frame, clad both sides with16mm high density boards, isolated from theinternal frame. The cavity is insulated usinglayers of sound absorbing materials asspecified to achieve the acoustic rating.Cladding boards are retained by removablealuminium edge profiles which do not formpart of the panel frame.

INTER-PANEL CONNECTIONSound leakage through the verticalconnection between meeting panels isminimised by aluminium interlocking wedge-shaped, tongue-and-grooved, edge profileswith integral magnetic strips. Profiles may beeither exposed, to protect the panel edge, orconcealed.

PANEL FINISHESPanels can be finished to suit almost everytaste and to match with adjacent décor.Standard panels are finished in durable,high-density melamine-faced particleboard,class E1. Other options include: laminates,selected wood veneers, primer sheet for on-site decoration with wall-coverings, and anycombination of these using dado rails andmouldings etc. Sections of pin-board andspecial absorptive acoustic boards may beincorporated; and for ultimate integration,inlaid veneered feature panels sourced andsupplied by the client’s appointed joineryspecialist.

OPERABLE ACOUSTIC SEALSThe acoustic seals are housed in deep, two-piece extruded aluminium carrier assembliesthat extend independently at the top andbottom of each panel. The black finishedcarriers have insulated bridging plates tominimise sound transmission. To ensure leakfree sealing and secure panel stability, theseal carriers operate under very high (2kN)spring pressure controlled by a manuallyoperated, rapid action scissor linkmechanism (with motor drive option). Ourscissor link device provides much longer sealtravel for out-of-level floors and facilitateseasy setting up of the panels by anyone,using a removable handle.

Our careful detailing makes these pass doorpanels probably the best inthe industry

Examples of how single ordouble pass doors can beincorporated into movablewalls.

PASS DOOR PANEL

A pass door panel needs very careful design detailing to minimise

sound leakage. The panel construction is as our standard panel but

has a bevel gear mechanism to operate full width seals at top and high-

pressure seals at bottom of both door stiles. The double rebated door

leaf is 100mm thick and is set within the panel having stiles at both

sides. An automatic adjustable pressure seal extends from the bottom

of the door leaf during last fraction of closing movement. Heavy-duty

hinges with adjustable sleeves are fitted, as are recessed lever handles

TELESCOPIC PANEL

Most movable wall systems incorporate a telescopic panel to provide

a working clearance for operator handling of the panels and achieve a

high-pressure, leak free seal at the jamb post. Panel construction is as

our standard panel but uses a bevel gear mechanism to actuate an

adjustable, internal extending section and the top and bottom seals,

sequentially in one winding operation. The extending section is finished

to match the panel surface, travels 100 mm carrying top and bottom

seal extensions to fully close into the corners. Operation is from one

side only.

* = DIN 52.210 Part 3 ** = DIN 4109 Supplement 3

When considering NoiseControl it is important to

appreciate the difference betweensound absorption and soundinsulation.

Sound Absorption refers to theattenuation of the reverberantnoise within the same room andtherefore it mostly falls outside thescope of a movable wall system.However when a sound wave hitsa movable wall some of its energywill be reflected and someabsorbed.

Sound Insulation, (also known assound reduction) is the preventionof noise being transmitted fromone area to another, by erecting apartition wall, for example. Theability of a partition wall to resistthe passage of sound energythrough it is largely determined byits mass, but structural isolationof the two surfaces and soundabsorbency of the cavities in theconstruction are other factorswhich enhance the overallperformance.

An Alco Beldan NW100 movablewall combines these 3 factors by:Using dense cladding boards toadd to the mass. Careful detailingof the internal components toisolate the boards from the innersteel frame and slabs of mineralwool infill within the cavity toincrease the sound absorbency.Attention to detail is all importantand that is why even the cavities of the seal carriers at top andbottom of the panel are filled withmineral wool.

The sound insulation level of amovable wall is graded by its

Sound Reduction Index (SRI). Thisis usually derived from the resultsof laboratory tests and isexpressed in terms of 'Rw dB',being a single figure based on aweighting system defined inBS/ISO/EN 20.140

Since the results of laboratorytests are obtained in perfectconditions where there is noflanking sound leakage, theycannot be replicated on sitewhere flanking leakage is alwayspresent at various levels. Thenormal loss between laboratoryand site performance is 3 to 8dB,depending upon how much carehas been taken to eliminatesound transmission paths. Nomovable wall nor partitioningcontractor can guarantee anyparticular 'on site' performancebecause flanking transmission isbeyond their control.

Naturally each manufacturer will tryto show their product provides thebest performance acoustically, butthe only way each product can becompared equally is by alaboratory test result. Recently thetesting method has been altered totake into account a wider range offrequencies and hence test resultsobtained prior to 1995 are invalid.The latest test procedures providetest results at frequencies from 0through to 5,000hz and theaverage figure is expressed interms of Rw. The relevantstandard is now BS EN ISO 140-3,1995 in which results areexpressed as Rw values only.

The performance scale islogarithmic which means it is

quite easy to achieve acousticimprovement at the lower end ofthe scale but very difficult toachieve significant improvementat the higher end. Its similar tosqueezing water from a saturatedsponge and partly explains why itis more expensive to raise theacoustic performance by 2dBfrom 52dB up to 54dB than it is toraise it from 41dB to 43dB. Anincrease in insulation of 10dB willcorrespond to a halving of theperceived loudness of the noise.

The perception of noise issubjective, some people havemore acute hearing than othersdo, and therefore we mustunderstand exactly what level ofinsulation the client is expectingfrom the movable wall. In mostcases the client's expectation ofnoise reduction levels cannot beachieved using panels rated lowerthan Rw 48dB, when flankingtransmission losses of 8dB aretaken into consideration.

Acoustic insulation is expensiveand it is tempting to try to makesavings, but this will be falseeconomy if the resulting noiselevel is still a nuisance.

Don't take risks. We can adviseyou and provide practical 'on site'results based on our experience.

ACOUSTICCHARACTERISTICSTo achieve the optimum audiblecondition in a room, it is necessaryto consider reverberation times.In general, a concert hall needsacoustically 'live' conditions,whereas a seminar room needsreduced levels of reverberation forintelligible speech.

Alco Beldan NW100 movable wallpanels can be faced with specialacoustic slotted boards whichcan improve the acousticcharacteristics of a room byincreasing the sound absorptionlevels. Refer to section on pages24, 25.

Noise is defined as unwanted sound and it is usually just a nuisance but at

times it can be a real headache. It invades privacy and causes disruption,

when all everyone wants is a little peace and quiet.

Movable walls are designed to divide areas of a room and control the level of the

noise or sound travelling from one area to another thereby reducing the nuisance,

creating an agreeable environment.

To determine the correct level of sound reduction for any particular circumstance is a complicatedprocess, and for an accurate appraisal, it is better to obtain the advice of an Acoustic Consultant.

However, it is possible to obtain a reasonably accurate prediction of expected performance by comparingthe results obtained by other methods of dividing rooms, and by using information from various sources, thetable shown below may help to identify the required level of noise reduction.

It is most important to remember when considering Fire Resisting movable walls, that only thoseproducts which have successfully passed the Fire Test are awarded a Building Control Certificate. Thereis no reason specifiers should be put off insisting on inspecting a copy of the test data by vague coveringstatements such as testing in accordance with ‘DIN 4102 F30 quality’ or ‘F30 A/B flammability’ sincesuch statements mean nothing.

FIRE RESISTING WALLS

Our type NW115 F is a

movable partition wall which

has been tested in accordance

with DIN 4102-T2 and achieved

60 minutes with class A2 (non-

flammable) cladding boards. This

was also tested with B2 (normal)

cladding boards and achieved 30

minutes. The same construction

was also tested for sound

reduction and achieved ratings up

to Rw 54dB in accordance with

EN 20140-3 (1995). This type

NW115F is also smoke resistant

to DIN 18095-2

SMOKE RESISTING WALLS

Our type NW100 RS is a

movable partition wall which

has additional modifications to

make it smoke protected in

accordance with DIN 18095-2

CLASS '1' SURFACE SPREADOF FLAME

If there is no requirement for fire

resistance specified and only

reduction of flame spread is

needed, we offer our type

NW100S. This is our standard

movable wall, which is

constructed almost completely

using non-flammable materials,

but with B1 (difficult to ignite)

cladding boards or sheet steel

covering. Although this

construction reduces flame

spread, it is not the same as the

'F' construction and therefore has

no fire resistance rating. It has no

General Building Control

Certificate.

CLASS 'O' FIRE PROPAGATION

In order to comply with the more

demanding Class 'O'

requirements, our NW100S

movable wall can be supplied with

A2 (non-flammable, no

contribution to combustion)

cladding boards.

Fire Resistance

As market leaders, Alco Beldan NW100 movable walls are now

available in five levels of Fire Performance. Options include Fire

Resistance of 30 and 60 minutes, Smoke Protection, Class '1' Spread

of Flame rating and Class 'O' fire propagation.

Alco Beldan are aware of newEuropean initiatives to

harmonise the various nationalFire and Smoke Regulations ofmember states within theEuropean Union. To prepare forthe introduction of new ENstandards, our Germanmanufacturing partner, FranzNusing GmbH & Co., hasdeveloped a new range of Fireand Smoke resisting movablewalls.

The new standard is DINEN1364-1. Fire protection inbuildings is a matter of PublicSafety and must be consideredextremely carefully and seriously.

The Specifier must first establishthe level of Fire Protectionrequired by the Authorities inrespect of a movable wall systemwhich is classed to as a ‘non-loadbearing wall’.

It must be remembered thatmovable walls are not self-closingand therefore cannot be classifiedwith a F30, F60 or F90 rating.Because of their mobility, the fireresistance rating of a movablewall only relates to itsperformance when in a closedposition with the seals fullyextended.

With something as important aspreservation of life, it is essentialthat products are appraised inaccordance with the testprocedures and certificates ofverification must be provided.When tested in accordance withDIN 4102-T2, a movable wallwhich successfully passes thetest will be issued with a GeneralBuilding Control Certificate.

The Alco Beldan NE115 F hasrecently been tested inaccordance

with DIN EN 1364-1 classificationand General Building Control TestCertificates have been issued for30 minutes and 60 minutes fireresistance. The sample testedincluded several inter-panel joints,grooves, fixings, wall posts etc.This is therefore a fully movablepartition wall which when fullyclosed and locked in position,achieved the same fire resistanceas a fixed wall. The NW 115 Fmovable wall system meets therequirements of the BuildingRegulations and currentlyrepresents the best movablepartition wall for the protection ofescape and rescue routes.

The new NW 115 F system hasbeen carefully developed from thestandard NW 100 S and manyfeatures are similar as detailed inspecification below:

Experience has shown that

movable walls are not

foolproof because the system

relies on the operator manually

extending the pressure seals at

top and bottom of each panel.

Whilst our rapid action

mechanism only needs 4 or 5

turns to extend the seals, when

pressed for time setting out a long

movable wall, an operator may

forget to extend the seals on

every panel. The result could be

complaints about the level of

noise through the movable wall.

Electrical operation of the seals

not only assures the seals will be

extended fully but also achieves

this without time consuming

handle winding, thereby

shortening the setting up process.

With Electric Operation the panels

are pushed into place as normal

but as soon as the magnetic

profiles engage together the seals

automatically extend applying the

correct pressure to give optimum

sound insulation and stability.

Electric OperationDesigned to Make Life Easier

Smoke Resistance

You now have the ideal

opportunity to incorporate

optimum smoke protection right

from the start when using

movable walls with the Alco

Beldan NW100RS, available now.

In the event of a fire, creeping

smoke is the greatest danger.

Most people perceive the

development of heat in a fire as

being the most dangerous

aspect; however fire experts

know the accelerated spread of

smoke has a higher potential for

danger. In such situations, escape

for the occupants of the building

along emergency escape routes

is made difficult and the dense

smoke hampers the job of fighting

the fire by the Fire Service.

For these reasons, fire protection

experts recommend that normal

smoke and heat extraction

equipment be supplemented by

the provision of smoke protection

doors and building elements

which prevent the spread of

smoke.

Until now, there has been no one

in the movable wall market to

provide a solution which lowers

the penetration of dangerous

smoke bearing gases into a room.

Movable walls which control

smoke give the occupants

valuable additional time, which

can save lives in the event of a fire.

Our technicians have modified the

standard NW100 panels and by

using a new sealing technique,

protected by German Patent No:

DBGM 299 03 466.6, have

achieved the improved smoke

retention characteristics.

When in the closed position, the

Alco Beldan NW100 RS movable

wall system complies with the

strict requirements of DIN 18

095/2, but offers no fire protection

rating.

www.alcobeldan.com

The Visioplan range of folding walls provide economic and versatile

solutions to your space division needs, where the ease of

operation of a concertina partition combines with the appearance of a

flat movable wall. An extensive range including fire resisting versions

and options for half and fully glazed panels

The main features of the VISIOPLAN range are:

• Pass door available, in most cases, at no extra cost.

• Choice of Floor Supported or Top Hung systems.

• Convenient handle operated securing bolts.

• Versatile range of decorative finishes.

• Glazed options in timber or aluminium frames.

• Fire resisting version available.

STANDARD VISIOPLAN

Visioplan systems are normally designed to run along a shallow, surface

mounted, aluminium floor track, but where structural support is

available, the top hung version without a floor track may be used. The

low profile floor track overcomes trip hazard and dirt accumulation

problems. Floor tracks must be fixed to a horizontally level surface.

Continuously hinged from a wall jamb, single wing panels fold to one

side of the opening with a single pass door as the last panel but a

double wing system offers a central, double pass door set. Pass doors

with 'D' ring handles and cylinder locks are standard.

Each alternate panel is located and secured with a self-adjusting bolt

using a convenient removable key handle. When bunching, the panels

may be folded equally on the track centre-line or eccentrically to one

side of track.

With the exception of most economical, Type 40, each panel has

understated aluminium profiles to protect the vertical edges and

complement the range of veneers, laminate, melamine or painted

surfaces which are available. Our wide range of acoustic ratings up to

Rw 46dB cover all but the most demanding situations.

This system can be top hungremoving the need of a floor track

Carden Park

Carden Park has been a significant Cheshire Estate since the 17th

century and its parkland makes an ideal setting for a luxurious hotel and

golf resort. The par 72, championship course, designed by Jack

Nicklaus, is served by a superb new clubhouse, catering for the variety

of corporate functions offered.

In order to optimise the flexibility of this two storey building, the

Architects wanted to use three, high quality, folding walls to divide the

first floor into four rooms which could be enlarged as necessary. The

structural support available from above varied, as did the required

stacking arrangements and the flexibility of the systems provided

ensure that the Architect was able to overcome all the design

obstacles.

Our Visioplan range of sliding-folding flat panels provided the ideal

solution. Being of composite construction, the internal acoustic

insulation was altered to match the requirements and the choice of top

hung or floor supported roller units, combined with centre-folding or

end-folding panels, meant this one product met the different conditions

at each of the locations.

In the bar area, the folding wall consisted of narrow leaf panels, which

are concealed, unobtrusively, in a deep narrow recess blending into the

end of the bar counter. In the main lounge however, a large feature

fireplace provides the opportunity to store the panels away within the

chimney breast and since these panels were top hung, centre-folding

and needed no floor track, there was no interruption to the run of carpet

through the two rooms.

It was equally important that the panels complement the interior decor.

The adjacent walls are finished with raised and fielded feature panels

and although it is not possible to fix timber mouldings to the surface of

the folding panels, a similar effect was achieved by routering a double

depth profile into the panel face. This example of lateral thinking

perfectly demonstrates how our clients benefit from our wealth of

technical expertise.

This installation made full use of the options available within the

Visioplan range and provided the perfect solution to each of the

individual challenges faced by the design team.

TIMBER FRAME

A series of custom made, timber framed panels, which are

continuously hinged and are easy to operate.

Available either top hung or floor rolling where structural support is not

adequate to carry the weight of the panels or when bunching off-centre

of the track. Sweep seals are fitted at top and bottom of each panel

to enhance the acoustic properties.

A pass door, fitted with a D-ring handle and latch, is usually included in

the run of panels at no extra cost. The door may be located in the

centre of the opening when using a double wing system.

Finished in high density paint as standard, panels are available in a choice

of finishes, extending to veneers, laminates or melamine and may be fully

glazed with a mid-rail or half glazed in clear or obscure glass.

ALUMINIUM FRAME

These panels are assembled from extruded profiles in white lacquered

finish providing clean attractive lines.

As with the timber-framed system, panels are top hung, requiring a

floor guide only when using end-folding configuration. Panels are fitted

with integral sweep seals at top and bottom edges, and are inter-

connected by butt hinges. Each alternate panel is secured at the floor

with slide bolts engaging into sockets, or the floor guide when using

end-folding stacking.

Horizontal or angled cross rails, to co-ordinate with the interior design

of the room, can be supplied and are recommended for use within taller

screens to meet safety requirements. In addition to the standard white

finished profiles and 6mm plain glazing, various alternatives can be

offered upon request. Remote stacking is also available using separate

panels on two-point suspension.

Glazed folding screens for internal use. Developed using the

successful Visioplan detailing, this refined, glazed version throws

new light on to an old subject, brightening your prospects by introducing

glass into the traditional timber framed panels or the clean, elegant

aluminium framed panels. Ideal for Day Centres, Schools and Hospitals.

Unrivalled StabilityFoldawall

Atraditional timber, double shell concertina folding wall with internal

link mechanism which when supplied with the floor rolling option

makes this a robust sliding partition with unrivalled stability.

A heavy duty, sound insulating, folding wall which may be either top

hung or floor supported for openings up to 4 metres high as standard.

The high-density chipboard leaves, with flexible acoustic seals at top

and bottom, are connected by metal piano hinges. Inside the double

shell construction, non-distorting internal pantograph units are

connected to a number of the folded leaves to provide unrivalled

stability. Aluminium leading edge profiles have magnetic strips for

positive closing with hook latch. An adjustable jamb post assembly

that needs no packing simplifies the wall fixing. Where required

shallow, load bearing floor tracks are available either surface fixed or

recessed, but both must be fixed to a level threshold. Available in a

range of finishes including melamine, laminates and veneers, with

certificated sound insulation ratings up to Rw 36dB.

Foldawall head detail

Amodern double shell concertina folding wall which closes flat, to

fill the gap between hinged folding walls and vinyl sliding-folding

partitions with a variety of options designed to provide an alternative

solution.

An easily operated folding wall with robust internal lever mechanism to

lock the panels absolutely flat when closed across a room, giving the

appearance of a flat smooth panelled wall without visible hinges. Top

hung with no floor guide. The leaves operate smoothly and quietly

along an aluminium overhead track. The deep section aluminium

leading edge profile incorporates a magnetic insert that combines with

a special action latch for positive closure. Once the door handle

releases the lever mechanism, the hinge system allows the bunched

leaves to fold back unobtrusively to the side of the opening. Adjustable

jamb posts mean the sides of the wall are neatly fixed without packing

or architraves. Available in a choice of finishes including veneers and

melamine with a choice of white or dark brown for the door handles.

Sound insulation ratings up to Rw 34dB.

Simple and EffectiveFoldacord

Foldacord vinyl sliding / folding partitions provide simple and

effective everyday room dividers where value for money is

important. They are ideal for applications where the available space

has to be changed frequently without fuss.

These top hung partitions are custom made to almost any size from a

servery hatch to a dividing partition for a large sports hall, but are

equally useful in schools, religious buildings, and of course, hotels and

restaurants. The neat regular folds of the vinyl covers are equalised by

a clever internal pantograph mechanism retaining a galvanised steel rod

framework which also facilitates the easy extension of the partition

across the opening. The mechanism is governed by a limiting tape,

which prevents over-stretching. When at the side of the opening,

bunched wings are retained by matching tie back straps. Curved tracks

and switching joints allow bunched wings to be stored parallel against

side walls instead of projecting into the opening. The washable, flame

retardant vinyl covers have seams reinforced with fabric webbing, and

are available in a wide range of colours and textures. With two frame

sizes available, your choice of acoustic insulation ratings extends up to

Rw 37dB.

Protective heavy duty webbing sewn to outer PVC coated fabric with nylon thread, and attached to hinge valley by self locking clips

High performance acoustic fabric (2 options)

Carbon steel pantograph action hinged to aid evenness of fold when opening the partition

Leading post trolley with a ball bearingaction and smoothrunning nylon tyres
