Ampelite is the largest and most experienced fibreglass and polycarbonate roof sheet manufacturer and distributor throughout Australia, New Zealand and Asia. The company commenced production from humble beginnings out of Melbourne in 1969, and today operates from offices and warehouses in all mainland states of Australia and in New Zealand.
Cool-lite GC provides diffused light, whilst transmitting only 23.5% total heat transmission! This helps provide a comfortable environment, and reduces energy costs associated with air conditioning and artificial lighting. Cool-lite GC also features the Ampelite’s Gel Coat technology.
Factories, supermarkets, warehouses, shopping centres, schools, gymnasiums and sports stadiums are prime examples of building where heat reduction sheeting is beneficial. In fact, in most single level buildings “Cool-lite GC” provides natural, diffused light that can replace, or supplement energy hungry electric illumination. If existing fibreglass sheeting is replaced with “Cool-lite GC”, transmitted temperatures and glare are reduced and air-conditioning efficiency is improved. All current and most superseded roofing profiles are available and there are no width restrictions. The special resins and colouring agents used by Ampelite are the best available, resulting in a very durable product. Both discolouration and scratch resistance are excellent and “Cool-lite GC” retains it great appearance with minimal maintenance.
Ampelite premium Industrial grade “Cool-lite GC” fibreglass is manufactured in strict accordancewith AS/NZS 4256 parts 1 & 3: 1994. Standards Licence No.986.
N.B.”Cool-lite GC” incorporates gel coat surface protection as used for “Wonderglas GC” premium grade sheeting. The highest quality materials available and the very latest resin technology are used in the manufacturing process. “Cool-lite GC” can also be manufactured to incorporate the fire retardant properties of Ampelite “SR76”.
Ampelite warrant series 2400 (and upwards) standard grade industrial fibreglass sheeting against damage from hail up to 20mm in diameter accompanied by winds up to 100 km/hr for 5 years. Premium grade gel coated sheeting is covered for 10 years.
|Industrial Standard and Premium Grades|
The above spans are recommended for wind loads up to 1 kPa.
For information regarding recommended spans in high wind and cyclonic regions please contact your local Ampelite office.
Important: Heavier grades give the specifier the option to use Ampelite sheeting in cyclonic zones, or match the span of the nominated steel roofing material (see ‘Spanning Capacity’).

The following installation procedures are recommended by the product manufacturers — Ampelite Australia Pty Ltd.
These recommendations closely follow the Australian Standard: Design and installation of Sheet Roof and Wall Cladding, Part 3: Plastic. AS 1562.3-2006
Where wire safety mesh is incorporated under the fibreglass sheeting and over a purlin, a protective purlin strip must be installed to prevent fracturing. Ampelite manufacture a 65 mm wide self adhesive fibreglass strip which, when viewed from below is not visible.
In roofing applications, fixings shall be fitted through the crest of any profile. Oversize screw holes from 10 mm up to 15 mm must be drilled at all points of fixing. Only 32 mm ‘Weatherlok’ seals should be used. These seals are large enough to cover the oversize hole and are sufficiently flexible to contour to any corrugation (or rib) when medium pressure is applied. Medium pressure means that the ‘Weatherlok’ seal is contoured to the shape of the corrugation (or rib), but rib or corrugation must retain its shape without any sign of buckling.
Contractors must make sure that the fixing is located in the centre of the oversize hole, or the benefit of the larger hole is lost. To ensure accuracy, Ampelite recommends the following:
- Fasten fibreglass sheeting in the same manner as metal.
- When Job is completed, remove fasteners on fibreglass section.
- Using the existing screw hole as a guide, drill an oversize hole, swap neoprene washer (used in step 1) with ‘Weatherlok’ seal and reinstall the fastener.
- Alternatively, Ampelite recommends the use of Fibreglass Teks or Clearfix industrial fasteners which drill an oversize hole as they fix.
Ampelite design and recommend the fibreglass sheets to be installed on top of metal roofing on both sides. The sheet rib can still go over and under when fibreglass sheets are installed side by side.
Where fibreglass sheets are end lapped including those with dissimilar materials, two lines of Lapseal Tape or a flexible sealant shall be placed across the full width of sheet. Each strip is placed approximately 150 mm apart with one line located 25 mm from the end of the fibreglass sheet. Ampelite recommends the use of 25 mm Lapseal Tape as silicone sealants can harden and cure due to exposure to daylight. The over-lapping sheets then become locked together as one sheet, effectively stopping movement between the sheets, and possibly causing buckling. With decking profiles install Lapseal Tape in the tray only or use a flexible sealant.
Fibreglass sheeting is not easily reshaped after manufacture, and will require special weather seals to be provided at all flashing and capping points. Typically, a foam closure strip matching the profile of the fibreglass sheet should be bonded to the pans or valleys with a flexible weatherproof sealant. Ideally it should be fitted at least 100 mm behind the turn down of the flashing.
Ampelite fibreglass sheeting (with the exception of Webglas GC) is a non-trafficable material. Sheets should be handled with care to avoid damage to the surface coating which is either Melinex film or Gel Coat according to the grade. Guarantees will not apply to sheeting that has been damaged in handling, or mechanical damage due to foot traffic.
Furthermore, unless the above instructions are strictly adhered to, Ampelite Australia Pty Ltd cannot accept any responsibility for consequent leakage problems, caused by sheets buckling or “ocean waving”.

Products: Industrial and Premium grade Industrial Fibreglass Sheeting. Manufactured to AS 4256.3-2006.
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.
Use: Generally as a translucent, light transmitting, panel in roofs or walls of buildings. May find use in specialty applications due to resistance to corrosion. Can also comply with Building Code requirements when using Fire Retardant resins.
Physical Description: Ampelite roof sheeting is the product of the halogenated polymerization of polyester resin by the addition of a suitable catalyst. The resin is supported by a matrix of chopped glass reinforcement. The sheeting is glass like in appearance and is odourless.
Ingredients: Polyester resin is an unsaturated thermosetting resin resulting from the esterification of suitable poly vasis acids and polyhydric alcohols dissolved in selected vinyl monomers. The catalyst system uses an addition of cumene hydro peroxide solution. The reinforcing is translucent sheet roving manufactured from E Type glass. The polymerization results in an inert resinous material.
Fire: Fire Retardant Sheeting has been tested in accordance with AS/NZS 1530.3-1999. It will support combustion and sheeting will only burn when flame assisted. All normal extinguishing media may be used. Thermal decomposition products include carbon monoxide, styrene, methyl methacrylate, acrid smoke and hydrogen chloride and bromide.
