Twin Wall Polycarbonate panels offer excellent insulation because of its ribbed configuration of the multi-walled sheets that trap air within the sheet, providing outstanding thermal insulation. Twin Wall Polycarbonate sheets are ideal for applications where specific light transmission is required. Twin Wall Polycarbonate has an impact strength 200 times greater than glass and 8 times greater than acrylic. It is 1/6 the weight of glass and 1/3 the weight of acrylic. Twin Wall Polycarbonate is compliant with most international standards for flame resistance, at very high temperatures, material melts but flames do not spread. This material will not crack or split when cut, sawn or drilled. Solar grade co-extruded layer protects the sheet against yellowing and surface wear from extruded UV exposure.

Twin Wall Polycarbonate sheets are designed for an endless range of glazing and roofing applications, for extreme weather conditions, and are known for their light transmitting and reflective qualities. They are attractive, durable, easy to install, and protect people and property inside a structure from the elements and from damaging UV radiation.
