Details:We had these panels for a project to be used as a trellis roof, but client opted for different color.
There are 6 clear sheets that are 4' wide by 19' 6" long. Includes the trim pieces that go in-between the panels. They have not been used and we paid over $2,300.
From Interstate Plastics Website (where we purchased them):
Major in construction and agricultural industries as well as many DIY applications. Polycarbonate has an impact strength 200 times greater than glass and 8 times greater than Acrylic. A solar grade co-extruded layer protects the sheets against yellowing and surface wear from extended UV exposure.
Endless applications for architectural design, roofing, windows, and installations
Hurricane and storm window/roofing protection
Light dispersion and transmission applications
