Storage information
Twinwall – It is very important that you keep the flutes dry. Please make sure that you keep your twinwall in a covered area away from water (moisture) and dust until installed correctly
Acrylic – Please keep the acrylic in a dry area as the sheet comes with a paper masking which is very hard to remove if wet.
Custom Glaze – Do not leave your sheet out in the sun as the protection cover can bake into the sheet. Keep undercover until installed.
Cleaning information
To keep your Polycarbonate and Acrylic roofing clean, we recommend cleaning it regularly using warm soapy water and a soft sponge, we do not recommend water blasting or using any other harsh cleaning chemicals as it can break down the protective U.V layer on Polycarbonate sheeting, these cleaners can also contain chemicals that are harmful to PMMA (Acrylic)
