3 | X-Technology 

4 | Fiberglass 

5 | Gypsum based ceilings 

Manufacturing Technologies 

• “ X” Technology is a unique manufacturing method wich was 

developed and introduced to the market by USG in 1989. 

This technology produces ceiling panels with ClimaPlus sag 

resistance and exceptional acoustical performance. 

• Wet-felted panels are typically mechanically perforated and 

fissured. They are very dense and more economical than other types 

of ceiling panels. 

• Cast panels are naturally textured and provide a unique, integral 

colour throughout the panel substrate with very good acoustical 

performance and enhanced extreme durability.

Acoustical Performance selector 

A balanced acoustical environment often plays an important part in 

improving productivity, comfort and peoples’ sense of well being. 

Through appropriate selection and placement of USG acoustical 

ceiling systems, it is possible to improve speech intelligibility, reduce 

unwanted noise or increase privacy within a space or between 

adjacent offices. 

Sound attenuation: 

“Sound attenuation” refers to the attenuation of 

noise passing into a room from outside, such as 

room-to-room noise or noise from above ceiling 

services. The test data in dB (DncW) for each tile 

gives guidance on the sound insulation, but they 

should be seen in the context of the overall room 

construction as per ASTM C423. fast and easy to 

install but also easy to remove without the need 

for tools. 

Sound absorption: 

“Sound absorption” describes the reduction of 

noise within a room. Acoustic ceiling tiles absorb 

sound energy and serve to control acoustic 

reverberation time. Different tile patterns provide 

different levels of sound absorption as per ASTM 

E1414. 

• NRC stands for Noise Reduction Coefficient. It is a measure of how 

sound is absorbed by a given material. It is listed as a decimal and 

relates to percentage sound absorbed. 

• CAC stands for Ceiling Attenuation Class. It is the measure of the 

blocking of sound through one ceiling plane, into the plenum above, 

and through the other ceiling plane to an adjacent space. 

Humidity resistance selector 

Extreme heat, humidity and fluctuating climatic conditions can 

shorten the life of a ceiling system. The connection of temperature to 

relative humidity (RH) is crucial in determining the best product for 

any application. USG’s specially formulated ceiling panels resist high 

heat and humidity without visible sag and are available in a range of 

performance options up to 100% RH/40°C. 

Acoustical ceilings absorb and/or 

attenuate sound. The two main acoustical 

performance ratings indicate panel 

performance: 

CAC: defines the amount of sound passing 

through a panel and the plenum into an 

adjacent space 

W, NRC: defines the average sound 

absorption of a ceiling system 

DncW: defines the average ‘room to room’ 

sound attenuation of a ceiling system. 

The USG ceiling tile range meets or exceeds the minimum requirements of BS8290 

(1991) as defined as: 

a. Normal environments 

(max. 25±2°C/65±5%RH) 

b. High humidity environments 

(max. 40±2°C/90±5%RH) 

• For applications in extreme environmental conditions such as exterior soffits, 

parking garages or swimming pools, products with 100% RH/40°C are 

recommended. 

Install with DONN Brand DX24-K corrosion resistant grid. 

• 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. 

• For applications with intermittent heating and cooling systems, products with 

90%RH/32°C or better are recommended. 

• For applications with normal controlled environmental conditions, products with 

70% RH/29°C or better are suitable. 

Fire rating selector 

Life safety and protection of property are important considerations in 

the design and specification of acoustical ceiling systems. Specially 

formulated Firecode (FC) rated ceiling panels are a crucial component 

of USG’s tested fire protection systems. Specification and installation 

must be in accordance with the selected fire test description of the 

system. 

Fire protection 

Structural fire protection BS 476 parts 21 and 23. 

Suspended ceilings can be used to provide protection to the structural elements of a 

building. In the event of a fire, the ceiling membrane protects the structure for a 

period of time enabling evacuation and fire fighting. The period of protection is 

determined by testing to BS 476 p23. Testing to BS 476 part 21, section 7, determines 

the protection provided to a loaded timber floor structure. 

In order to ensure the validity of a “fire protecting” ceiling, installation must be as 

described in the relevant test report. Any alteration may affect the fire protection 

capabilities of that ceiling system. 

Class A signifies that a panel is non-combustible based and has attained a flame 

spread index of 25 or less on ASTM E-84 testing procedures. 

Firecode signifies that a panel has been classified as a protective membrane in 

accordance with the standard ASTM E 119. It can be used in a UL fire-rated assembly 

to achieve a time-rated assembly. The time rated assembly includes the entire floor- 

ceiling or roof-ceiling assembly. All firecode protective membranes offered by USG 

have attained a Class A rating. 

Warranty 

USG offers a lifetime (30 year) limited 

warranty on ultra high performance tiles 

and a 15 year limited warranty on high 

performance tiles when installed on USG’s 

DONN Brand suspension grid. Refer to USG 

technical services for details. 

USG ceiling systems must be installed and 

maintained in accordance with current 

USG written instructions and industry best 

practice as defined by 

BS 8290. 

Reaction to fire 

17 

Ceiling products are generally considered 

suitable for multi-use buildings when the 

products conform to BS 476 part 6 and 7. 

BS 476 part 6 is the fire propagation 

classification which compares the constitution 

of combustible materials to the development of 

fire – performance class 0. 

BS 476 part 7 is the surface spread of flame 

classification which indicates the tendency of

Light reflectance selector 

The Light Reflectance selector identifies USG ceiling panels that 

efficiently reflect light within a space to enhance indirect lighting, 

reduce energy consumption and create a warm, luminous aesthetic. 

Measured per ASTM E14771, LR value represents the percentage of 

light reflected from the surface of a material. The industry average for 

panels is LR .70 to .80, and values above LR .85 are considered high. 

USG offers numerous panels with LR values at these levels, including 

SONATA, MARS CLIMAPLUS, OLYMPIA II and OLYMPIA MICRO 

PERFORATED, with LR .89. 

• Choosing high-LR ceiling panels is a great way to improve the utility and comfort 

of the spaces you design and make your projects bright and inviting. Indirect lighting, 

combined with high-LR panels, can eliminate dark, shadowy areas and too-bright hot 

spots, improving the look and feel of a space and minimizing eyestrain (a cause of 

employee fatigue). 

High-LR ceilings can also help conserve energy and cut operating costs by achieving 

the same light levels with fewer fixtures and lower-wattage bulbs. Fewer fixtures also 

mean less repairs and lower maintenance costs. 

Architects typically select high-LR ceiling for spaces that make extensive use of 

indirect lighting. However, these panels can enhance almost any lighting scheme and 

so can be an effective choice for many design applications. 

Many USG panels with high LR values also feature high NRC and CAC ratings so you 

dont have to compromise acoustics for aesthetics. Panels are available in a range of 

textures including smooth and very fine, many include CLIMAPLUS performance, and 

several are cast products, which provide a higher level of durability to resisit and hide 

scrapes and scratches.

Specialized Performance 

Many interior environments with demanding functions (such 

as food preparation, hydrotherapy, exercise, athletics and 

cleanroom control) require performance beyond aesthetics, 

sound control and sustainability. USG offers many options to 

meet a diverse range of specialized performance needs. 

Abuse resistance 

Routine plenum access can blemish panels with unsightly scratches, 

and chips and dents can occur in high – traffic areas such as 

hallways, classrooms and gyms. When durability is key, consider the 

following products. 

Specially formulated mineral-fiber ceiling panels feature higherdensity 

construction and special finishes to enhance durability and 

damage resistance. Panel include: 

RADAR TM CLIMAPLUS TM High-Durability panels deliver 20% greater 

durability than competitive “school products” and 50% more than 

standard acoustical panels. 

MARS TM CLIMAPLUS TM panels resist visible damage in independently 

verified surface scratch tests and withstand 150 scrub cycles without 

surface break using the Gardner Scrubability Test, per ASTM D24861 

Cast ceiling panels, available exclusively from USG, are formed 

and cured in molds, making them up to three times stronger than 

standard panels. Cast panels feature an integrally color-coordinated 

substrate to mask nicks or scrapes. Panels include: 

• Frost TM CLIMAPLUS TM 

• Glacier TM 

• Sandrift TM CLIMAPLUS TM 

Humidity Resistance 

Moist air in indoor pool areas, shower and locker rooms, and 

buildings not fully enclosed can cause standard panels to visibly 

sag. For high-humidity areas, choose panels with CLIMAPLUS 

performance. These products resist sag in up to 95% relative humidity 

and up to 104 °F. RADAR TM Ceramic CLIMAPLUS TM panels even resist 

sag in up to 100% relative humidity. CLIMAPLUS products carry a 

limited warranty of up to 30 years when installed in a DONN ® brand 

suspension system. 

Fire Resistance 

USG offers many ceiling panels with 

FIRECODE TM formulation, which provides special 

additives for increased fire resistance. Fire-rated 

suspension main tees are manufactured with 

relief notches that will contract in high heat to 

hold the ceiling assembly together and prevent 

collapse. Fire-rated panels and suspension 

system components are identified with the fire 

icon on the individual product pages in this 

catalog. 

CLEANLINESS 

Cleanrooms, food preparation areas and 

computer rooms require ceilings with specific 

attributes and performance levels. CLEAN 

ROOM TM CLIMAPLUS TM Class 10M-100M and 

Class 100 panels feature vinyl laminated 

surfaces and meet Federal Standard 209E, 

“Clean Room and Work Station Requirements 

Controlled Environments”. SHEETROCK ® brand 

CLEAN ROOM TM lay-in ceiling panels with 

gypsum core, sealed edges and vinyl face and 

back, can also be used in cleanrooms up to 

Class 100. Cleanroom-rated applications require 

a suspension system with gasketed tees such as 

the DONN ® CE system. 

For food preparation areas, choose Class 100 

panels or SHEETROCK ® Vinyl CLIMAPLUS TM layin 

ceiling panels, which meet U.S. Department 

of Agriculture Food Safety Inspection Service 

requirements. 

Exterior Applications 

Exterior soffits and ceilings in open parking 

garages and marine environments are subjected 

to large temperature swings, wind, humidity 

and incidental water exposure. USG offers 

several products that can be used in these 

challenging applications: 

• DONN ® ZXLA TM hot-dipped galvanized 

suspension system with aluminum cap 

• PARALINE ® linear metal ceiling system, windload 

tested to 120 mph. 

• USG drywall suspension system for flat 

ceilings. 

Sustainability 

Sustainable Design 

Sustainable design seeks to create structures that require fewer 

natural resources to build, maintain and adapt to future uses. Key 

strategies include choosing quality, lasting materials and creating 

flexible, multi - functional spaces. 

Consumers have become increasingly aware of the need to conserve 

energy, manage raw materials, reduce waste and safeguard against 

pollutants. In response, many developers and owners now demand 

buildings that will help save energy, preserve the integrity of 

surrounding land and assure a clean, healthy indoor environment.

Design that require fewer Natural resources: 

• Energy conservation 

• Raw Material Management 

• Waste Reduction 

• Safeguard against pollutants 

In response, many developers and owners now demand buildings that 

will help save energy, preserve the integrity of surrounding land and 

assure a clean, healthy indoor environment. 

1 | Indoor Environmental Quality: 

Indoor environmental quality (IEQ) refers to all environmental factors 

that affect the health and well-being of building occupants. IEQ 

includes such factors as Indoor Air Quality (IAQ), comfort, humidity, 

air exchange, acoustics and lighting quality. 

Many USG ceiling panels help to support healthy environments with 

reduced Volatile Organic Compound (VOC) emissions 

Formaldehyde Performance: 

Formaldehyde is an important industrial chemical used to make 

chemicals, building materials, and household products. 

Exposure The OSHA Permissible Exposure Limit (PEL) for 

formaldehyde is 750 ppb (0.75 ppm) per 8-hour TWA (Time Weighted 

Average, the average exposure over an 8-hour work period). 

Content The presence of formaldehyde must be reported if the 

concentration of formaldehyde exceeds 0.1 percent of weight. All 

USG ceilings are well below these levels. 

To help building professionals create healthy spaces, USG offers many 

ceiling panels and tiles that emit no formaldehyde or such low levels 

as to exceed stringent standards established by the collaborative 

for High-Performance Schools (CHPS). This high performance comes 

standard on these products, with no additional charge or lead time.

Post-Industrial (Pre-Consumer) materials 

are generated by manufacturers and processors, 

and may consist of scrap, trimmings and 

other by-products that were never used in 

the consumer market. Post-Industrial and 

Pre-Consumer are one in the same under the 

USGBC LEED ® rating systems. 

Post-Consumer material is an end product 

that has completed its life cycle as a consumer 

item and would otherwise have been disposed 

of as a solid waste. Post-consumer materials 

include recyclables collected in commercial and 

residential recycling programs, such as officer 

paper, cardboard, aluminum cans, plastics and 

metals. 

Binders are derived from corn and wheat starch, which are renewable 

agricultural resources. The metal in many of our specialty ceiling and 

drywall suspension systems includes recycled content. Aluminum 

offers additional benefits in that it can be fully re-purposed by 

re-melting and salvaging the metal. 

Responsible Manufacturing 

USG ceilings = high recycled content (HRC) 

Recycling is only a part of the story. Careful production methods 

are good for the environment and increase efficiency. Our practices 

include: 

• Using clean fuels (NG) 

• Treating and recycling water (Saving of 300 m3 daily at USGME) 

• Reducing waste (Recycling) 

• Offering specialized ceiling panels 

• Recycling old ceiling panels 

• Product life cycle

used to create the ceiling substrate) 

3 | LEED 

LEED ® is a guideline for building solutions established by the USGBC 

(United States Green Building Council) members. USG Corporation is 

a founding member of the U.S. Green Building Council. 

The Leadership in Energy and Environmental Design (LEED) is a 

rating system that encourages the design and construction of 

environmentally friendly buildings 

LEED was created to define “green building” by establishing a 

common standard of measurement and promote integrated, wholebuilding 

design practices. 

Credit are awarded based on the five key areas of human and 

environmental health: sustainable site development, water savings, 

energy efficiency, materials selection, and indoor environmental 

quality. 

Choosing zero-emitting and low-emitting ceiling products can also 

help earn LEED credits. Section 3.2, IAQ Management Plan, Before 

Occupancy, requires a total formaldehyde concentration of 50 ppb or 

less. As one of the largest surfaces in a space, a ceiling with zero – or 

low – emitting panels makes a strong contribution toward achieving 

valuable credits – and creating healthy, sustainable environments.

Ceiling panels with high light reflectance(LR) can reduce the number the 

number of light fixtures needed, curbing energy consumption. 

Cast-minereal-fiber panels are baked solid in molds for abuse resistance and 

through color to resist abrasion and mask scrapes. 

USG offers a nationwide recycling program that can take back approved 

mineral-fiber panels, reducing impact on landfills. 

Panels may contain synthetic mineral fiber converted from slag, a by product 

of steel making. Metal ceilings and components may include recycled 

aluminum. 

Panels may contain paper recovered from both pre-consumer and postconumer 

use. 

See the Sustainability section of USG's Ceiling System 2007/2008 (SC 2000). 

Panels may contain corn and wheat-strach binders, renewable alternatives to 

traditional petroleum-based binders. 

All USG products are low-VOC emmitters and many panels emit no 

formaldehyde or only a very low amount. 

Ceiling panels with high light reflectance(LR) can improve the quality and 

quantity of natural light by enhancing indirect lighting.

Water Resistance Ceiling Tiles 

"Water Shield" 

In its continuous improvement, USGME offers 

an invention in mineral fiber 

ceiling tiles. 

Normally, the ceiling tiles have a tendency to stain when in contact 

with water due to condensation on pipes and duct work 

above the ceiling. 

The condensate can drip into the backside of the ceiling tiles and 

migrate to the visible side of the tile. 

The water droplets can leach tannin from recycled materials and 

other cellulosic based materials and staining agent from the 

paint surface of the tile. 

USG’s new invention provides an economical solution to minimize 

water stains at the visible face of the panel. 

This invention creates a barrier to water droplets at the backside of 

the panel allowing the droplet to evaporated before 

it can migrate through the panel. 

This treatment provides a Water Shield to mineral fiber tiles 

in a practical and cost effective way.

Installing a DONN ® grid system 

Step 4

Step 2 

➊ 

➋ ➌ 

Steps 5/6 

➊ Main Tee 3600/3660mm ➋ Cross Tee 1200/1220mm ➌ Cross Tee 600/610mm ➍ Hanger 

The appearance of a suspended acoustical ceiling is dependent both on the 

materials used and on the quality of the installation. USG manufactures components 

to meet BS8290 & BS EN 13964, assuring that the material, structural 

and quality standards are as prescribed. Installation must meet BS8290, assuring 

proper level and secure attachment as prescribed.Good construction conditions 

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. 

max. 450mm 

Step 1 

Measuring 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). 

➊ Main tee 

3600/3660mm 

➋ Cross Tee 

1200/1220mm 

➌ Cross Tee 

600/610mm 

Step 2 

Mark 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). 

x Hanger positions 

Step 3 

To 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 4 

Attach 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 5 

Install 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 6 

Lay 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 7 

Removal 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 8 

Main 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 

75 

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 

Materials 

All 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.

USG Middle East Limited 

Loadings - DONN ® DX ® 24mm Exposed Grid 

Ceiling Mass - Kg/m 2 

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 independently 

supported. 

• 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. 

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 lm 

therefore 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 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.

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 Profiles 

When 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 Fittings 

Light 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.

86 

Grid edge solutions 

DONN DX is the most widely specified grid in Middle East. It includes a wide range of 

profiles and colours and is fully compatible with all USG ceiling tiles as well as most 

third party brands. Precision design and quality manufacturing ensure both structural 

and aesthetic integrity in all ceiling designs. 

USG offers the following suspension system and 

edge details options. Select a suspension system 

and match it with a corresponding panel edge

Installation and maintenance 

System performance 

USG 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 handling 

Storage 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 direction 

With 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 material 

Wherever 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 conditions 

For 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. 

87 

Maintenance and cleaning 

General 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-decoration 

It 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 products 

In 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.

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.

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.

Ceiling Systems Warranties and Limitations 

All ceiling products and suspension systems must be installed and maintained in accordance with 

USG written installation instructions for that product in effect at the time of installation and best 

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: 

Performance Level

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)
