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.
