Extended Warranty to 20 years!        Sheet Cross Sections        SHGC is solar heat gain coefficient

Lengths: In ft increments 4 – 48 ft.          Sheets over 26′ require dedicated truck, and high ship costs.

* Bronze expansion & contraction can be extreme, as Bronze gets hotter than clear, white/opal or Softlite.
* Opal polycarbonate light transmission is the lowest, is best for areas that could get hot and hides dirt.
* Sheet must be Installed with ribs vertical on walls and with the slope on roof. Minimum Roof Slope 5º (1/12)
* Install ribs vertical same direction as sheet length * Sheet size listed width x length.
