Clear Twinwall Polycarbonate



Twinwall Polycarbonate is an ideal product for where optical clarity is required, but heat retention/deflection is also important, such as in greenhouses, sheds etc. Here at TW Plastics, we currently offer this Twinwall Polycarbonate in 4mm thickness and in Clear.

Twinwall Polycarbonate is also very light in weight (0.9 kg/m²) compared with annealed glass, making it much easier to lift and position. Due to the durability of the product, installation is simple with minimal risk of breakages occurring.

The excellent thermal insulation of this Twinwall Polycarbonate is due to the walled cells inside the hollow structure of the sheet. It has a much higher insulating ability than other single walled, corrugated or solid flat sheets; with the U value of 3.8 W/m²K. (The U value is a number, which measures the quality of thermal insulation. Lower values for a material relate to superior thermal insulation):

The 4mm Twinwall Polycarbonate has a high light transmission rating of 82% which allows sufficient light to enter whilst featuring a UV coating that is designed to protect the sheet against the effects of UV rays (ultra-violet radiation) which occurs in direct sunlight. UV will not be transmitted through these sheets, which makes it an ideal product for areas where constant exposure is expected.

Twinwall Polycarbonate can be used for a variety of applications, such as: frames, greenhouses, sheds and other small domestic structures and is easily cut, sawn and drilled.
