It is most commonly manufactured from polycarbonate or polypropylene and is widely used in construction, glazing, and protective applications.

Key Features

• Multi-layer structure Two or more parallel walls joined by internal webs for added rigidity

• High light transmission Allows natural daylight while diffusing glare

• Excellent thermal insulation Air pockets between layers reduce heat transfer

• Impact resistance Especially strong when made from polycarbonate

• Lightweight Much lighter than glass with similar strength

• UV protection Often coated to resist yellowing and degradation

• Weather resistant Withstands rain, snow, wind, and temperature extremes
