Premium polycarbonate sheeting that allows maximum light whilst stopping harmful UV rays and "near infra-red" heat radiation.

Twinwall Sheeting

Twinwall sheeting combines the strength of polycarbonate with superior insulation due to its cellular structure. This provides more light with less heat and double sided UV protection, providing 99.9% protection of harmful UV and impact resistance 250 times that of glass.

This material is appropriate for both commercial and domestic structures such as pergolas, walkways, facades, skylights etc.

Multiwall Polycarbonate Roofing

Multiwall polycarbonate glazing systems provide outstanding flexibility in design and advanced heat reflecting and light transmitting performance. An advanced construction of internal walls and chambers gives excellent insulation properties and impact strength 250 times that of glass. Both sides of the sheet have a co-extruded UV barrier which provides protection from 99.9% of harmful UV radiation, giving superior resistance to outdoor weathering. Multiwall systems ensure high impact strength, clarity and excellent weather resistance.

Multiwall sheeting is appropriate for long-term applications such as architectural roofing and glazing, commercial and retail roofing, translucent roofing in sporting facilities and service stations, covered walkways, awnings and entrances, parking structures and swimming pool covers.

Note that Multiwall Polycarbonate Roofing is available in a kit that includes a framing system that allows for wider spans with less structural support.
