 Frequently Asked Questions

1. How do I install polycarbonate roofing sheets?
To install polycarbonate roofing sheets, start by measuring and cutting the sheets to size. Use appropriate fixings and leave expansion gaps. Secure the sheets to a suitable frame with compatible fasteners, ensuring correct overlap and orientation (UV-protected side facing out if applicable). Always follow the manufacturer’s guidelines for best results.

2. How do I seal polycarbonate roofing sheets to a wall?
Use a compatible sealant or flashing to seal the joint between the sheet and the wall. Apply sealant along the edge of the sheet and press it firmly against the wall. For added weatherproofing, consider using end closure profiles and wall flashings.

3. How do I cut polycarbonate roofing sheets?
Polycarbonate sheets can be cut using a fine-toothed circular saw, jigsaw, or handsaw. Secure the sheet to prevent vibration and ensure a clean, straight cut. Always wear protective gear and handle the material with care to avoid cracking or chipping.

4. How do I join polycarbonate roofing sheets?
To join sheets, use H-profile connectors or aluminium glazing bars designed for polycarbonate. These not only provide structural integrity but also help with water drainage and thermal expansion. Always allow room for movement due to temperature changes.

5. How do I fit polycarbonate roofing sheets?
Fitting involves placing the sheets on the roof structure with the correct overlap, fixing them with proper screws or fasteners, and sealing edges and joins. Consider wind direction, slope and support spacing to ensure durability and weather resistance.
