4mm Twinwall Polycarbonate Greenhouse Glazing

Mainly used for Greenhouse glazing, the sheets are manufactured from damage-resistant polycarbonate with added co-extruded long life protection from the effects of UV rays. Polycarbonate has very high impact resistance and fine optical clarity. The high performance UV absorption layer means longer life and prevention of yellowing and loss of strength. Polycarbonate offers excellent protection against vandalism and accidental damage with an impact resistance up to 200 times greater than glass. This characteristic is maintained over a broad temperature range and prolonged service life.
