4mm Twinwall Polycarbonate Greenhouse Glazing

Mainly used for Greenhouse glazing, 4mm twinwall sheets are manufactured from damage-resistant polycarbonate. This has added, co-extruded long life protection from the effects of UV rays. The high performance UV absorption layer means longer life and prevention of yellowing and loss of strength. Polycarbonate is incredibly strong with very high impact resistance. 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. Polycarbonate also has fine optical clarity.
