Notes on Opal Polycarbonate:
The white tint in Opal provides a pleasant light diffusion that reduces glare and overheating. 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.
