Axiome Opal effect Polycarbonate Multiwall Roofing sheet (L)2.5m (W)690mm (T)16mm.Axiome light-weight glazing sheets are manufactured from polycarbonate and have a protective UV layer on the outer side. The opal (white tint) colour provides extra privacy compared to clear sheets whilst reducing heat transmission with its higher reflective properties. These sheets offer superior light transmission rigidity and thermal insulation properties and are a light weight solution. Axiome multiwall polycarbonate won’t shatter like glass and the sheets can be easily cut to shape or size with a fine-tooth jigsaw or similar.
