Poly 101 PDF - How To Install Polycarbonate Panels 

1" Thick

25mm (1") 3-Wall channels trap air between 3 walls.  This polycarbonate panel provides more strength, insulation and clarity. The strength comes from the full 1" thickness. The high insulation value of R 2.64 is provided by the extra thickness and middle layer. Wide flute spacing of 3/4" allows Clear panels to have excellent clarity and light transmission. Choose Clear or Opal.

Installation: The flutes (channels) run the length of the panel. Install panel with flutes vertical. Panel ends should be capped or sealed with a vented tape that allows interior condensation to escape. Dimensions + or - 1/8".

Opal & Bronze Polycarbonate

The white tint in Opal provides a pleasant light diffusion that reduces glare and overheating. Unlike the Bronze panel, Opal allows more of the growing light spectrum needed by plants for healthy growth.

Opal is recommended for roof applications, especially in Southern states, and at higher elevations where solar radiation can be intense. The insulating, internal air space reduces condensation, making it ideal for a patio roof.

Bronze tint is attractive and is ideal for patio roof and walls. It provides shading, privacy, and minimizes condensation.
