Features
This unique system offers daylighting, high insulation value, UV screening, and resistance to abuse, all in one high performance, low-cost package. The same technology that makes standing seam roofing watertight is present in the EXTECH system, with the added advantage of light transmission and insulation.
• Panels are nominally 2ft. wide and are available in lengths to 39ft. Continuous polycarbonate battens snap over the panel edges to form the seams.
• Natural lighting is diffused by the cell structure of the EXTECH panels, thus eliminating harsh lighting effects.
• All aluminum framing is fitted with low-friction gasketing and deep glazing pockets which capture and hold the polycarbonate sheets, yet allow thermal movement of the panels.
• Perimeter framing is engineered with interlocking components to allow access to individual panels as desired.
• Standing seam systems eliminate the need for vertical aluminum mullions, thus creating a monolithic appearance and lowering costs compared to conventional daylighting systems.
• The patented #3100 type-1 clip, which anchors the sheets to the purlins, allows the thermal movement of the PCSS sheets to take place within the clip, thus minimizing noise and wear.
• The #3100 type-2 clip system (also patented) allows for movement in all planar directions and compensates for misalignment of the building substrate.
• Perimeter aluminum framing is available in anodized or high performance paint finishes and is available thermally broken.
• Insulation values are in the same range as 1" insulated glass. Superior values are obtained with double glazed polycarbonate systems.
