How does the Opal Heatguard Polycarbonate work?
Opal Heatguard Polycarbonate is specially made for us in North America. It is 1″ thick for better insulation and composed of 5 layers for strength and durability. The outer surface actually reflects heat and the opal inner surface gives off a smooth, diffused light. It is extruded with a UV barrier on the outside to prevent degradation from sunlight.
