Polycarbonate roof sheeting is manufactured using modern co-extrusion technology to create a highly UV stabilized weathering surface on the sheet. This layer will not crack or delaminate and ensures years of trouble-free performance in the harsh South African weather conditions.
Polycarbonate sheeting is resistant to mineral acids, numerous organic acids, and salts solutions, fats, and oils. Polycarbonate is not resistant to petrol, benzine, keytones, acetone, phenols, petroleum-based paints and carbon tetrachloride.
Polycarbonate may be cleaned using a mild soapy solution. Abrasive cleaners should not be used, and any other agents should be tested before use.
Polycarbonate must be stored under cover and on pallets. Exposure to moisture/rain while stacked together will result in damage to the sheets.
Polycarbonate sheets are manufactured to provide a specific amount of light transmission. Various standard colours and levels of light transmission are manufactured.
|Purlin spacing:||1.3 meters for horizontal/roof application|
|1.5 meter for side cladding|
All fixing holes should be drilled oversize, polycarbonate has a very high co-efficient of linear expansion – a 10 metre sheet will expand by 17mm for a rise in temperature of 25°C. All fixing laps should be fixed at every corrugation. Polycarbonate can be cut using a band saw, circular saw (tungsten carbide tripped), or shears.
