Multiwall Polycarbonate

Multiwall Polycarbonate is an ideal product for where maximum optical clarity is required, but heat retention is also important. Using this product to aid heat retention will contribute to savings on gas, electricity by reducing the need for heating or air conditioning; which is a top priority for homes, businesses or public buildings.

Here at TW Plastics, we currently offer three thickness variations for you to choose from: 10mm Twinwall, 16mm Triplewall and 25mm Sixwall; all are available cut to size at request and the relevant fittings and accessories are available to order.

Multiwall Polycarbonate can now be supplied in Clear, Opal or Bronze. These variations in colour allow you to restrict light transmission, which is sometimes required on certain applications such as on South or West facing roofs.

Light transmission ratings are as follows (Clear/Bronze/Opal):

Multiwall Polycarbonate is also very light in weight 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 Multiwall 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 following U values (The U value is a number, which measures the quality of thermal insulation. Lower values for a material relate to superior thermal insulation):

The product features 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.

Multiwall Polycarbonate can be used for a variety of applications, such as: Conservatory Roofing, Car Ports, Smoking Shelters, Greenhouses and many more. A variety of fittings and accessories are available.

Cut to Size Service: Please note that the flutes must run down the length of the sheet therefore all measurements must be given in length x width.
