Polycarbonate Sheets & Roofing

How should polycarbonate sheets be installed to last?

• Place the branded face (POLY TOP sheets) upward so the UV-protective layer faces the sun.
• Keep the roof slope at no less than 5 degrees so water can wash dirt away easily.
• When bending, keep the sheet axis aligned along the whole sheet and do not bend tighter than a 1 m radius.
• Do not over-tighten fixings or drilled holes, since the sheet expands and may crack.
• Seal both open ends with tape to keep dirt out of the sheet channels.
• Clean only with a cloth dampened in clean water with mild soap.

Polycarbonate Sheets for Roofing, Awnings and Translucent Walls

Polycarbonate sheet is an engineering plastic that is nearly as clear as glass but many times more impact resistant at half the weight. The outer face carries a UV coating, so it resists yellowing, which makes it the standard choice for polycarbonate roofing, awnings, carports, walkways and partitions that need daylight.

Types of polycarbonate sheet

• Twin-wall polycarbonate: 6-10 mm hollow sheets whose air channels cut heat; they curve easily; 1.22x2.44 and 2.1x6 m
• Solid polycarbonate: 3-6 mm, glass-clear, for clear roofs, walls and decor
• Embossed polycarbonate: solid sheet textured on one side to diffuse light and hide scratches
• Double-wave, mini wave and metal-sheet profiles: laid between existing roof tiles or metal sheets to add daylight

Benefits and how to choose

For most roofs and awnings, 6 mm twin-wall is the go-to: light and good at blocking heat. Wide purlin spans or windy sites call for 8-10 mm. Pick solid sheet when you want glass-like clarity. Clear lets in the most light, while bronze, grey and opal tints cut glare and heat. Always install with the UV side up and finish the edges with translucent sheet accessories such as U-channels, caps and end caps to keep water and dust out of the flutes.
