Installation

Fixing Details

Ampelite sheeting shall be installed in accordance with Ampelite fixing instructions and with AS/NZS 1562.3:1996, Design and installation of sheet roof and wall cladding, Part 3: Plastic. Please note these additional requirements:

Ampelite translucent sheeting matching positive fixed profiles shall be installed using the fastening screws applicable to the main cladding, together with a 32 mm Weatherlok washer. This combination gives a secure and weathertight finish. The fixing screws should not be overtightened to an extent that the sheet buckles, allowing water penetration at the seal or sheet overlap.

Fixing should be made at every crest at both ends of the sheet, and every second crest at intermediate purlins.

Where Ampelite fibreglass sheeting is in CONTACT WITH SAFETY MESH a Protective Foam Strip (75 mm x 5 mm), or a 70 mm Fibreglass profiled Isolation Strip, should be installed over the safety mesh, to avoid fracturing of the underside of the sheet.

Where END LAPPING is required a minimum of 300 mm overlap is essential. On profiles such as corrugated, 5-rib or similar, we recommend the use of 25 mm Lap Seal Tape at the top and bottom edges of the purlin. This ensures the strips are concealed. For Decking profiles, two continuous beads of a clear non-hardening sealer (i.e. silicone), must be applied across the full width of the decking within the overlap. End lapping should only be applied to roofs with a minimum pitch of 5°.

IMPORTANT: Ampelite sheeting should be installed by pre-drilling oversize holes to allow for expansion and contraction. The basic calculation is 0.75 mm per lin./m, plus shank diameter of screw. Do not overtighten screws.

EXAMPLE: 10 m sheet - 10 (m) x 0.75 (mm) + 4 mm (fastener) =11.5 mm pre-drilled hole.

Recommended maximum length of the sheet is 12.2 metres.

Clip fixed Decking

Ampelite sheeting matching clip-fixed deck profiles shall be installed in conjunction with the main cladding and should be side lapped with overlaps on both sides (Ampelite sheets have 2 female laps). Fixing of sheets should be carried out in the same manner and practice as those stated for positive fixed profile roofing.

Wall Cladding  

Pan fixing is required at each girt, and use of Ampelite grey dome 22 mm weatherseals ensures a weathertight seal. Overtightening or flattening the weatherseal must be avoided. Fixing shall occur in every pan at both ends of the sheeting, and every other pan at intermediate girts. 

Cyclone Zone Installation 

Installation in cyclone prone areas follows the recommendations and code for normal fixing, but further specific requirements must be met. Please contact your local Ampelite office for the latest information.

End Closure Strip

Foam filler strip is available to suit most profiles. This strip should be installed at the ends of the sheets to exclude dirt, birds and vermin.

Storage

The sheeting should always be stored in a dry and fire safe area. Do not store heavy materials on top of sheets as they may fracture.

Waste disposal

Do not incinerate fibreglass off-cuts as burning produces acrid smoke and noxious, toxic fumes.

Non-trafficable

Ampelite translucent sheeting is a non-trafficable material. Sheets should be handled with care to avoid damage to the surface coating (Melinex polyester film). Guarantees will not apply to sheeting that has been damaged in handling, or mechanical damage as a result of foot traffic.

Safety Data

There are no ill effects from handling 'Ampelite' Fibreglass sheets as a finished product.

Some exposure to air-borne particles occurs on drilling, cutting and trimming of the material. Although there are no known cases of harmful effect, even after long term exposure, it is recommended to take certain precautionary steps.

Effects of exposure to dust particles.

Eye (contact)
Can cause irritation. Appropriate eye protection should be worn. If irritation occurs due to exposure to dust particles, wash eyes with running water using an eye bath or wash bottle. If irritation persists seek medical attention.

Skin (contact)
Can cause irritation. Shower thoroughly using soap and a cloth or sponge.

Inhalation (breathing)
Dust masks are recommended although particles are not respirable.

Ingestion (swallowing)
Non-toxic. Extensive studies have revealed no serious effects.

Emergency Fire Fighting Action

In the case of an indoor fire relating to stored Fibreglass Sheets the following action is necessary.

Use a self contained breathing apparatus.

Fire may be controlled by use of sand, carbon dioxide, dry powder or foam extinguishers,  Water can be used to prevent fire from spreading to other goods or buildings.

For further information contact your local Ampelite Sales Office.


Waste Disposal

Do not incinerate fibreglass off-cuts as burning produces acrid smoke and noxious, toxic fumes.


Warranty

Fire Retardant SL features a limited 10 year warranty. For full warranty details, please contact your nearest Ampelite office.
