High Quality Polycarbonate Greenhouse Glazing

Polycarbonate is the best greenhouse covering due to its performance in extreme climates like wind, hail, snow, wildfires, and extreme temperatures. 5-Wall glazing (16mm thick) is the standard for all our kits because it will perform well in all climates.
