Installing a DONN® grid system74

Step 1Measuring and planning are key first steps in the

installation process.

Measurement and placement of the tees will be on centre

(o.c.), meaning from the centre of one to the centre of

the next. Planning starts with a drawing of the room

that shows all walls, including bays, alcoves beams and

stairwells. Note which direction the joists (if any) are

running, or if architectural drawings necessitate working

in one direction or another. Determine the lines for main

runners and cross tees in such a way that the tiles that

about the wall are at least half a tile (300mm).

Step 2Mark the desired ceiling height (maintaining at

least 70mm clearance below the lowest duct, pipe

or beam.)

Measure and mark the walls at all corners above the

installation level (= add the height of the wall angle to

the desired ceiling height.) Snap a chalk line and test for

level. Measuring down from joists or up from the floor is

not recommended, since neither may be level. Install wall

angle with top edge of angle at the chalk line, spacing

appropriate fixings 450mm o.c. or closer. Cut and mitre

outside and inside angles at 45°, fitting them snugly

together. Alternatively, simply butt angles at corner (as in

system illustration).

➊

The appearance of a suspended acoustical ceiling is dependent both on the materials used and on the quality of the installation. USG manufactures com-ponents to meet BS8290 & BS EN 13964, assuring that the material, structural and quality standards are as prescribed. Installation must meet BS8290, assur-ing proper level and secure attachment as prescribed.Good construction condi-tions are very important when successfully installing a suspended ceiling. It is recommended that the temperature and humidity range be 14 – 25°C and max. 75% relative humidity. Store materials in a protected area, store tiles on the job at least 3 days prior to installation.

Step 3To confirm level, stretch a string until taut along

the positions which the main tee will occupy.

Inserting a nail between the wall and the wall angle

at marked locations serves as a good anchor for this

purpose. Stretch another string across the room where the

first row of cross tees will be located. This identifies where

the first prepunched slots need to fall. Check to be sure

the cross tee string is at 90° to the main tee string via the

3-4-5 method. Install the hangers at 1200mm o.c. above

the lines of the main runners. Fix to the structure above

using appropriate plugs, screws or other devices.

Step 4Attach the main runners to the hangers.

In each row, trim the main tee so that the cross-tee slot

will line up with the cross-tee string. Mount main tees,

resting the cut end of the main tee on the wall angle. The

cut end of the main runner should be about 5mm away

from the wall.

Step 5Install cross tees, assuring that they are

adequately connected to main tees (they “click”

in place when properly seated).

Where two cross tees intersect in the same slot, insert

second cross-tee end to the left of the first. Where a

cross-tee is installed without an opposing cross-tee, a nail

should be slipped into the opening of the cross-tee clip to

maintain the pull-out value for the cross-tee.

Step 6Lay in panels, beginning at one corner and

completing row by row.

Tilt each panel up through the opening and lower it to

rest squarely on all four tees.

Step 7Removal as easy as installation.

Just grasp the main tee with one thumb under the main

tee-cross tee connection and, pushing up with the thumb,

give the main tee a quick, short twist. That’s all it takes –

no tools needed. The strong clip means that the grid can

be reinstalled straightaway with no tearing or bending of

the clip.

Step 8Main tee demounting

Using a straight shearing motion, push with your left hand

and pull with your right hand to disconnect the main

runner splice. Note: do not twist the splice during the

removal procedure

Other installation tips A Cut tees with aviation snips, first the stem and then the flanges.

B Cut mineral fibre panels with utility knife and straight edge, cutting the face first. Cut panels

should be at least 15mm larger than the opening.

C To install panels around obstructions, draw their exact locations on the panels and cut out. Then

cut the panel in two parts through the largest section of the cut-out to enable fitting.

D To trim for Shadowline edge, use a utility knife to cut the panel, first at the face, then from the

edge, to the same depth as Shadowline. If windows, stairwells, etc., extend above the ceiling plane,

build suitable valances and attach wall angle.

DONN® DX24 Intermidiate Duty 76

MaterialsAll USG suspension systems feature a body and cap made of hot-dip galvanized steel. To ensure that the cap remains attractive and rust-free for long term, manufacturing includes an exclusive four-step coating process that outperforms the competition in paint adhesion and corrosion resistance, as proven by industry-standard salt spray tests conducted by an independant laboratory.For our extreme environments we offer our grid system, with hot-dipped galvanized steel body and painted aluminum cap for additional corrosion and humidity resistance.

Uniform Loads - kg/lm (linear metre)ْUniform loads are loads that are transferred evenly along a given tee.The maximum load is the combined load on both sides of the tee.Example:A 1200 x 600 light fitting weighing 12.6 kg applies a load of 3.5 kg/lm(1.2 + 0.6 + 1.2 + 0.6 = 3.6 lmtherefore 12.6 kg / 3.6 lm = 3.5 kg/lm)A 1200 x 600 ceiling panel weighing 3.6 kg applies a load of 1 kg /lm The combined load of light and ceiling panel is 4.5 kg/lm.The maximum allowable uniform load is the lesser of either main or cross tee values.

Point Loads - kgPoint loads are loads that transfer to a tee at a single point (or several points) over a very small area. The weakest point is assumed to be mid span. main tees are based on a 1200mm span.The maximum allowable point load is the lesser of either main or cross tee values.

Loadings - DONN ® DX ® 24mm Exposed Grid

Ceiling Mass - Kg/m2

Use of Maximum Allowable Gross Ceiling Weight Charts:

• Determine the maximum allowable ceiling weight for the chosen Main Tee and hanger spacings from Graph.• Determine the maximum allowable ceiling weight for the chosen Cross Tee spacing from table.• The maximum allowable gross weight is the lower of the values from step 1 and 2.• Note that any heavy lighting, or other mechanical fixtures should be independentlysupported.• Siesmic considerations for in-plane loads may take precedence in determining the required section (refer USG Representative for detalis).

NOTES:•Values are based on simple span tests in accordance with recognised International Standard ASTM C635. Higher values can often be attained by allowing for the effect of continuous spans, the actual increase being subject to span arrangements. Please contact USG Interiors for guidance.• For cross-nogged configurations e.g.: where a 1200x600 mm panel runs parallel with the main tee, the spacing values should be used as for 1200x1200mm module.• Where main tees are at 1200mm centres, creating a 600x600mm configuration does not significantly increase load carrying limits.

DONN® DX®

As worldwide leaders in acoustical ceiling systems, USG Interior works with the major lighting manufacturers to ensure system compatibility is maintained. The following guidlines are designed to assist in the correct specification and installation of light fittings in USG's DONN Exposed Grid and acoustical ceiling systems.

Luminaire Positioning Typical recessed pan fitting arrangements are shown below. Main Tees at 1200mm centres are shown horizontal, with suspension at 1200mm centres.• Refer to Loadings (page 64 this brochure) for maximum allowable point loads, uniform loads and gross ceiling loads depending on type of luminaire and DONN grid selected.Where luminaire weight exceeds point or uniform load maximums consider:a) A higher specifications DONN grid option if applicable (refer to Loadings page 64 this brochure to ensure compliance).b) Independent support from structure.c) Additional suspension points as shown below, or similar.

DONN Grid ProfilesWhen recessed pan fittings use the top of the DONN tee bulb for support, use the same height tee profiles for even support.

Ceiling panel Mounted FittingsLight fittings mounted through USG acoustical ceiling panels shall not rely on the ceiling panel for support. Their weight shall be transferred back to the grid by:

a) Simple supports across the back of the ceiling panel.

b) Simple supports onto the top of the tee bulb.

c) An additional rigid panel across the back of the ceiling panel.

Installation and maintenance 87

System performanceUSG ceiling systems should be installed in accordance with recommendations described within this

catalogue and the DONN grid application guide. System performance following any substitution of

materials or compromises in assembly cannot be guaranteed and may result in failure under critical

conditions. Reference should be made to BS 8290 1991 Suspended Ceilings parts 1, 2 and 3, and

the European Standard for Suspended Ceilings BS EN 13964:2004.

Site storage and handlingStorage on site should be as short as possible with environmental conditions as near as possible to

those specified for occupancy (see below). Any storage area should be secure and fully protected

from the weather with cartons stored on a clean, dry base. Cartons of material should never be

rolled, dropped or slid, and under no circumstances used as a workbase or substitute for ladders,

scaffolding, etc.

Pattern directionWith directional face patterns, such as Glacier and Sandrift, the orientation of pattern relative to

light sources should be carefully considered for desired visual effect, and specified and installed

accordingly. Variations in colour and fissure size in Glacier and Sandrift ceiling tiles will be of little

consequence within a single production batch. However, minor variations can occur from time to

time, and projects should be planned so that all material for continuous ceiling space is ordered and

delivered from the same production batch. Some USG tiles are marked with a directional arrow on

the back and should always be installed with this in alignment to ensure total consistency of pattern

and paint shade in a Production batch.

Overlaid materialWherever possible, overlaid material such as insulation, should not be laid directly on the back of

the ceiling membrane, as this will compromise the fire resistant properties of the ceilings. In normal

conditions (BS 8290), overlaid material should not exceed 3.6kg/m2 weight. For high humidity

environments, overlaid installation shall be limited to 1.2 kg/m2.

Installation/environmental conditionsFor applications with normal controlled environmental conditions, products with 70% RH/29°C

or better are suitable. Installation should only take place under ambient conditions after residual

moisture from concrete and plaster has dissipated.The recommended relative humidity should not

exceed 70% RH within a temperature range 65-85°F, 18-29°C for installation and occupancy.

Once ceiling installation has commenced, it is essential that RH% and temperature be maintained at

acceptable levels by heating the building if necessary. Dry heating should be employed and paraffin

or gas heaters avoided. These recommendations should still be applied between completion of

contract and the occupation of the building. Unoccupied buildings with uncontrolled atmospheres

may have a wide temperature range during a 24 hour period which could lead to an unacceptable

change in dimension stability of the ceiling panels, causing excessive sag.

For applications with intermittent heating and cooling systems, products with 90%RH/32°C or

better are recommended. (See Humidity selector, page 15.)For applications with uncontrolled

environmental conditions, natural ventilation systems or in humid areas such as washrooms, kitchens

or wet process areas, products with 95-99%RH/40°C or better are recommended. (See Humidity

selector, page 15.)Radar Ceramic and Sonatone ceiling panels perform especially well in areas such

as swimming pools, where the ceiling may be subject to unusually high levels of humidity up to

100% RH and chemical attack. They should be installed with USG DONN Corrosion Resistant ceiling

grid and appropriate hangers to resist corrosion.

All USG tiles should be protected from sustained direct contact with water except the treated one

as water shield.

Maintenance and cleaningGeneral cleaning of dust and loose dirt may be easily

achieved using a soft brush or vacuum cleaner. Soiled

panels can be cleaned with an art gum eraser or

dampened cloth or sponge containing as little water

as possible.

Clean Room tiles can be wet wiped on a regular basis

without damage.

Panels should never be soaked or immersed in water.

Cleaning can also be carried out by specialist

contractors using proprietary methods and

chemicals. It is strongly recommended that a trial

area be cleaned to ensure that there is no detrimental

effect on the ceiling panel or grid.

Re-decorationIt should be noted that a new paint finish may

compromise the Surface Spread of Flame classification

and acoustic absorption for that panel.

Please consult the USG Technical Services Department

for expert advice and recommendations.

Custom productsIn addition to a wide standard range, USG can

satisfy specifiers’ needs for non-standard, specialised

ceilings. Please talk to your local USG representative

to arrange production of your specific ideas.

Ceiling Systems Warranties and Limitations88

All USG DONN brand suspension systems, when used with any USG ceiling panels or tiles or

SHEETROCK brand gypsum lay-in ceiling panels, carry a lifetime (30-year) warranty that our products

shall be free from manufacturing defects and that the suspension systems shall be free from

the occurrence of 50% red rust as defined by ASTM D610 test procedures for 30 years from the

date of installation.

USG ceiling panels and tiles with CLIMAPLUS performance are specially formulated to endure

environments with up to 100% relative humidity and temperatures up to 104 F. these panels carry a

limited warranty against visible sag for 30 years when installed in a DONN suspension system.

Sag resistance is measured under 'Standard Test Method for strength Properties of Pre-fabricated

Architectural Acoustical Tile or Lay-in Ceiling Panels'.ASTM C367-05.

The Test Method cautions (Section 17.3) that it "is not designed to establish the expected

performance of the ceiling panels under field conditions of use, but only the sag properties for the

specific temperature, humidity, exposure time and mounting conditions used in the test.

Neither this test method nor any other laboratory test we are aware of can predict long-term sag

resistance. we do know that the higher the relative humidity and temperature, and the longer the

time these conditions prevail, the more susceptible to sag are the ceiling panels, Nevertheless, USG

has offered sag resistant ceiling panels for more than 20 years, and we have very rarely received

sag complaints. this excellent field performance is expected because the formulations of both core

and/or backing, depending on the particular panel, inherently impart sag resistance. Avoidance of

extreme temperature and humidity conditions are regular cleaning will enhance sag resistance and

all other performance attributes of the ceiling panels.

USG CKIMAPLUS ceiling panels with superior performance are warranted to be free from the

growth of mold, mildew, and Gram-negative odor- and stain-causing bacteria for 30 years from the

date of installation. these ceiling panels include an antimicrobial treatment on the painted surface

that contains a mold-inhabiting agent that provides broad-spectrum control for the growth of mold

and mildew over the warranty period; these ceiling panels also resist the growth of Gram-psitive

and Gram-negative odor and stain causing bacteria.

CLIMAPLUS fiberglass and RADAR Ceramic CLIMAPLUS ceiling panels do not have Superior

performance antimicrobial treatment;they are warranted to be free from the growth of mold,

mildew, and odor-and stain- causing bacteria for 30 years from the date of installation due to the

inherent characteristics of the products.

CLEAN ROOM CLIMAPLUS and SHEETROCK CLIMAPLUS gypsum lay-in panels do not feature

the Superior performance antimicrobial treatment and therefore are not included in the 30-Year

Antimicrobial System warranty.

All USG limited warranties are subject to use under normal conditions. abnormal conditions include

exposure to chemical fumes, vibration, moisture from conditions such as leaks or condensation,

excessive humidity, or excessive dirt or dust buildup.

By "lifetime" we mean the useful life of the ceiling system, up to a maximum of 30 years.

Lifetime (30-Year) Limited Warranty

89

The CLIMAPLUS warranty periods for these and other USG products and systems are as follows:

All warranties are subject to the following terms and conditions:

Exept where stated otherwise on specific product warranties, all USG warranties cover original

owner of the building at the time of installation.

In the unlikely event of product performance failure, at our election USG will replace the goods

or we will refund or credit an amount equal to the (original) purchase price of the goods within

warranted conditions.

The building owner is responsible for all costs associated with removal and installation.

All ceiling products and system must be installed and maintained in accordance with current USG

written instructions and best industry practice, including the CISCA Handbook and ASTM C636.

"Standard Practice for Installation of Metal ceiling suspension system for Acoustical tile and lay-in

panels. "SHEETROCK Gypsum panels used with USG Drywall suspension system are not covered.

Also, you must observe the following:

-Care must be taken that the products are not damaged during delivery and while they are stored

at the job site.

-The products must always be protected from vibration, direct contact with water including

condensation, and chemical fumes, both before and after installation.

-These products may not be used in exterior applications, The only exception is RADAR Ceramic

CLIMAPLUS, which may be used in exterior soffits.

Except for ceiling with superior performance, CLIMAPLUS fiberglass ceiling panels and RADAR

Ceramic CLIMAPLUS ceiling panels, the growth of mold or bacteria is not covered by this warranty

nor it is the responsibility of USG. All products should be maintained to avoid excessive dirt or dust

buildup or the presence of excessive moisture that would provide a medium for microbial growth on

ceiling panels.

Damage that may occur from vibration,fire, water, freezing temperature, accident, any form of abuse

or exposure to abnormal conditions is no covered in this warranty.

If subject to abnormal conditions, the products should be removed immediately and replaced once

the conditions are normal.

industry practice. Prior to, during, and after installation, the ceiling product must be kept clean and

dry, and maintained in an environment free of chemical fumes or vibration, not subject to abnormal

conditions and within the following conditions:

for RADAR Ceramic CLIMAPLUS ceiling panels: the sag performance warranty extends

toinstallations where the ceiling product is exposed to environments subjest to temperatures of

60-104° F (16-40° C), chemical fumes, steam, and up to 100% RH, including standing water

applications, so long as the product is installed with either AX or ZXLA suspension systems. For

swimming pools, install only with AX or ZXLA suspension systems. For outdoor soffits, canopies and

parking garages, install with ZXLA suspension system (wind uplift should be considered).

For all CLIMAPLUS products (excludes CLEAN ROOM CLIMAPLUS and SHEETROCK gypsum lay-in

panels): these ceilings must be maintained to avoid excessive dirt or dust buildup that would provide

a medium for microbial growth on these panels or tiles. Microbial protection does not extend beyond

the treated surface as received from the factory, and does not protect other materials that contact

the treated surface such as supported materials.

Prior to, during, and after installation, the suspension systems (excluding DXLA, AX, ZXLA and the

USG drywall suspension system) shall be maintained in a temperature range of 60-104° F (16-40°C)

and relative humidity shall not exceed 90%. DXLA shall be maintained in a temperature range of

60-104° F (16-40°C) and relative humidity shall not exceed 95%. AX, ZXLA and the USG Drywall

suspension system shall be maintained in a temperature range from 60-104° F (16-40°C) and

relative humidity can be up to 100%.

The warranty does not cover rusting that occurs from building leaks or condensation.

The ceiling panels must not be used to support any materials including insulation. Where insulation

must be used, it should be on heavier than 1.27kg/m2 and installed with the following USG

recommendations: insulation must be applied perpendicular to the suspension cross tees with the

suspension system supporting the weight of the insulation. insulation is also not recommended

to be used as follows: Firecode applications, unless specified and use described by underwriters

laboratories, Inc. Mold or mildew growth on insulation or placed above the ceiling panel or tile are

not covered by this warranty.

This warranty does not cover damage caused by fire, water, accident, or by any form of abuse except

normal wear and tear.

Please see USG written instructions about proper maintenance, touch up, and repainting of our

ceiling system. Please note that not all products can be repainted and that repainting will affect

acoustical performance, appearance, microbial resistance, fire resistance, and ventilation through the

ceiling panels or tiles.
