Opal Diffused & Bronze Polycarbonate
PoliSoft Diffused provides a pleasant light diffusion that reduces glare and overheating. Unlike the Bronze panel, PoliSoft Diffused allows more of the growing light spectrum needed by plants for healthy growth.
PoliSoft Diffused (light transmission 79%) is recommended for greenhouse and 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. (6mm, 10mm, 16mm, and 25mm are available in traditional Opal that would make light transmission about 47%.)
Bronze tint is attractive and is ideal for patio roof and walls. It provides shading, privacy, and minimizes condensation.
