Polycarbonate 4mm

Polycarbonate 4mm.

Polycarbonate sheets stand out with very high impact resistance even at low temperatures, mechanical strength. Due to its transparency, lightness, impact resistance and very good thermal conductivity, cellular polycarbonate is widely used in roof and wall constructions, greenhouse coatings, terrace and gazebo constructions, carport constructions, pool coverings and much more.

 From our experience , 4mm polycarbonate is good for 4-7 years. In comparison 6mm polycarbonate will last 5-12 years. 

If you are located in windy , snowy place, we strongly suggest choosing 6mm polycarbonate!
