Polycarbonate Profile sheeting (Corrugated, Greca & 5 Rib)
The Calypso is our most cost effective option with a 10 year weather breakage warranty.
The Calypso Ultra is a higher grade polycarbonate which is sold with a 25 year loss of light warranty and a 10 year weather breakage warranty.
Corrugated profile sheets are 840mm wide with a 755mm cover.
Greca profile sheets are 810mm wide with a 760mm cover.
5 Rib Profile sheets are 840 wide with a 760mm cover
All of our sheeting is sold with a small sticker on the side which faces the sun. This sticker has our branding which corresponds to the sheeting purchased.
You can cut the sheets with a pair of tin snips or a circular saw with a fine toothed blade.
We recommend cleaning the sheet with warm soapy water. Use a soft sponge or cloth and avoid using anything with hard bristles as it can scratch the sheet. It is not recommended to water your sheet.
We recommend fixing every second rib for the corrugated and greca profiles and every rib for the 5 Rib profile. There is a fixing calculator on the product page which is useful to work out the number of fixings required.
All profiles must be installed on a 5° pitch or 88mm rise per lineal meter.
Yes, all of our Polycarbonate sheeting blocks out 99.9% of the harmful U.V
Yes you can, but we would only recommend curving the corrugated profile. Refer to below image.
Our Polycarbonate sheet will last anywhere from 10 to 30 years depending on the quality and brand purchased
PVC sheeting is not as strong or as durable as Polycarbonate making Polycarbonate the superior choice for roofing. A good quality Polycarbonate will have a U.V coating on one side which means it will stand up to the elements far better than PVC
Polycarbonate Twinwall Sheets
We recommend cutting the Twinwall with a straight edge and Stanley knife. A saw tends to blow swarf into the flutes.
The Twinwall is UV protected on both sides so you install it either side facing the sun.
Yes, it is important to seal the ends with our Anti-Dust Tape and Polycarbonate Capping. This prevents water, dust and bugs from getting into the flutes. You do not want moisture getting into the flutes.
We recommend only spanning the Twinwall 600-700mm across rafters or purlins. Anything wider and you risk the sheet sagging.
A full installation guide can be found on our website here:
No. The Twinwall MUST be kept inside out of the weather.
Twinwall is the term used for sheeting with only two walls, Multiwall is the term that is usually used for sheeting with more than two walls
Flat Acrylic and Polycarbonate Sheets
Polycarbonate is stronger than Acrylic and has 250 times the impact resistance of glass.
Acrylic has roughly 17 times the impact resistance of glass.
Acrylic is rigid and has much better optical clarity than polycarbonate. In the long term, this means it will hold its clarity for a longer period of time with out fading or going cloudy. This makes it ideal for awnings and Pergolas.
Polycarbonate is more flexible but does not hold its clarity as well as Acrylic does.
Polycarbonate is much more expensive compared to Acrylic.
