6mm Opal Twinwall Polycarbonate Panel

Our 6mm twinwall polycarbonate offers the same high impact resistance and excellent heat retention as the standard 8mm material. The Opal (white) tint of this panel offers 20% light transmission making it a great solution for extremely hot or sunny environments. The thinner profile of this 6mm panel is perfect for hobby greenhouses or patio coverings.

ThermaGlas Multi-wall Polycarbonate Sheet is designed and engineered specifically for commercial greenhouse use. ThermaGlas products are available in 6-foot widths in clear, or with specially formulated colors and tints. ThermaGlas offers 99.5% UV protection. The multiwall design and light weight of the sheet enables a reduction in the cost of the supporting structure. Shatterproof polycarbonate coupled with integrated UV resistant co-extruded layer yields long service periods backed up by a 10 year limited warranty. The cellular multi-layer structure reduces heating costs in winter while minimizing excessive heat in summer. A special coating on the bottom side eliminates condensation dripping. ThermaGlas blocks ultraviolet rays that burn plants and living tissues, and transmits only beneficial radiation.
