Polycarbonate vs Corrugated PVC Roofing Sheets
28 September 2022 | Admin
A question that we get asked a lot by customers is which sheets should I choose for my project - polycarbonate sheets or corrugated PVC sheets? Unfortunately, the answer is not a straightforward as the question and will depend on a number of factors. We will try to untangle some of these below:
Polycarbonate Roofing SheetsGenerally, the polycarbonate used in roofing applications is multiwall, triplewall or twinwall. Polycarbonate panels for roofing should be 10mm thick or greater and the thickness you require will largely depend on the level of insulation your roof requires. For most lean to, carport and canopy installations 10mm thick sheets are perfectly adequate.
Polycarbonate is easy to install, lightweight and extremely durable. Roofing sheets are supplied with a manufacturer’s 10-year warranty but should outlast that by many years.
Sheets cut very easily using a jigsaw, circular saw or hand saw with a fine toothed blade – just remember to fit breather tape to cut sheets.
Structured polycarbonate is generally fitted alongside glazing bars which join the sheets together. Whilst it can seem like this is extra work – glazing bars are very easy to fit and once ‘snapped together’ will give a watertight join between your roofing sheets.
Corrugated PVC Sheets
Corrugated PVC roofing sheets are probably the easiest sheet to fit in our range. Sheets simply overlap one another to give the appearance of a continuous wave across the roof. Corrugated roofing sheets are supplied in a number of profiles. 3” ASB (the old asbestos profile) is by far the most popular sheet but we also distribute 6”, greca and miniature corrugated PVC too. Sheets are available in a number of thicknesses from 0.8mm thick for basic domestic applications to 1.3mm thick for structural and commercial applications.
Corrugated roofing sheets do not need glazing bars like polycarbonate roofing sheets and therefore many consider them to be the easier sheets to install. However, it is worth noting that corrugated sheets need the roof to be fitted with battens. This means there may be more work required prior to installation.
