Our 10mm multiwall polycarbonate sheet combines high light transmission, thermal insulation and excellent weather resistance.

The sheet is lightweight, impact resistant and easy to install. It features a co-extruded UV-protective layer on one side of the sheet which provides almost total resistance against degradation caused by UV radiation in sunlight and almost no UV radiation passes through the sheet. This UV protected side must be installed facing outwards.

Our range of multiwall sheet carries a Ten Year Limited Warranty against discolouration, loss of light transmission and/or loss of strength due to weathering.

Maximum Service Temperature (without load)

Our multiwall polycarbonate sheet can be installed in a diversity of applications with varying temperatures. The material’s mechanical performance is known to remain stable in prolonged service in temperatures between -40°C up to 120°C.

Fire Performance

Our multiwall polycarbonate sheet has good fire behaviour characteristics, and receives high ratings in several major European fire performance tests. As a thermoplastic, our multiwall polycarbonte will melt under the intense heat of a fire, however, it will make almost no contribution to a fire through flame spread.
