SL Group 3 Bromine Free Fire Retardant

Overview

Ampelite announces the next generation of SL Group 3 Fire Retardant sheeting with a ‘Bromine Free’ formulation. To meet the Internal Surface Performance requirements of the New Zealand Building Code, Ampelite’s SL Fire Retardant sheeting was originally manufactured from a fire retardant resin that used a chemical called Bromine. Bromine is a very good fire retardant, however it can change colour and become a yellowish brown colour when exposed to UV and heat. A substantial amount of Research and Development work has been undertaken in order to achieve a Group 3 rating without the use of ‘Bromine’.

New ‘Bromine free’ formulation.

This product is often referred to in a number of different ways including the following, Fire retardant roofing and sheeting, fire rated roofing, group 3 rated fire retardant roofs / roofing, NZ building code compliant roofing product, ISO 5660 fire tested roofing product.

Ampelite SL FIRE RETARDANT sheeting has been specifically developed for Commercial and Industrial Structures requiring good natural lighting, combined with the need for fire retardant roofing and building materials
Warranty

SL GROUP 3 BROMINE FREE FIRE RETARDANT Industrial Fibreglass Roofing sheeting features a 25-year warranty

SL GROUP 3 BROMINE FREE FIRE RETARDANT sheeting utilises the same highly UV resistant surface as Ampelite WonderGlas S-996 (Formally Wonderglas GC). Like our WonderGlas S-996 SL GROUP 3 BROMINE FREE FIRE RETARDANT sheeting is protected by the same highly UV resistant Silmar 996 gel coat which is integral with the sheet and cannot de-laminate. WonderGlas GC (Now Wonderglas S-996) was tested at Allunga Queensland, through the Allunga Exposure Laboratory. Allunga is an independent laboratory that specializes in natural weather testing, and is well known in Australasia and overseas. All methods of testing are performed to strict Australian Standards. The WonderGlas GC (Now Wondeglas S-996) technology was developed in the United States through BP Chemicals, and has been in the American market for in excess of 25 years and widely used throughout New Zealand since 1995.

SL GROUP 3 BROMINE FREE FIRE RETARDANT sheeting is also available in our Permaglas range where the need for a more cost effective solution is required.

Accessories

Ampelite have a large range of accessories available to help make the installation of SL Group 3 BROMINE FREE Fire Retardant Sheeting quick and professional. These accessories include a range of self-drilling that oversize the fastener holes as they pass through the sheet and self-adhesive tapes and profiled form filler strips for vermin protection. Please download our Industrial accessories brochure.

Correct installation is important

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, the requirements of the NZ building code and the NZ Metal Roofing Manufactures Association Code of Practice. For full installation details please download a copy of our installation guide.

Please note these additional important requirements
  • Ampelite translucent sheeting matching positive fixed profiles shall be installed using the fastening length applicable to the main cladding, together with a metal profile washer and EDPM seal. This combination gives a secure and weather tight finish. The fixing screws should not be over tightened 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 fiberglass sheeting is in contact with safety mesh a Ampelite purlin protection strip must be installed over the safety mesh, to avoid fracturing of the underside of the sheet.

  • Where end lapping of the sheet is required a minimum of 300 mm overlap is essential. Ampelite 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.

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

  • 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 weather seals ensures a weather tight seal. Over tightening or flattening the weather seal must be avoided. Fixing shall occur in every pan at both ends of the sheeting, and every other pan at intermediate grits.

  • 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.

Handling, Storage & Disposal

SL Group 3 Bromine Free Fire Retardant Sheeting Industrial Fiberglass Sheeting is a non-trafficable roofing material. The sheeting should always be stored in a dry and fire safe area and handled with care to avoid damage to the surface coating as warranties will not apply to sheeting that has been damaged in handling, or mechanical damage as a result of foot traffic.

Fiberglass sheeting is not recyclable and should be disposed of in a land fill. Do not incinerate fiberglass off-cuts as burning produces acrid smoke and noxious, toxic fumes.

Polycarbonate sheeting is recyclable and can be returned to a specialist plastic recycling company or disposed of in a land fill.

Safety Data

There are no ill effects from handling 'Ampelite' Fiberglass 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.

  • 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: Dust masks are recommended although particles are not respirable.
  • Ingestion: Non toxic. Extensive studies have revealed no serious effects.
