Reduce high greenhouse heating bills using 8mm triple wall polycarbonate panels. With a U-Factor of .50, our triple wall panel is 14% more energy efficient than standard 8mm twin-wall. Triple wall structure offers high impact resistance, excellent heat retention and 76% light transmission. Includes anti-condensate coating to prevent dripping.
ThermaGlas Multi-wall Polycarbonate Sheet is designed and engineered specifically for commercial greenhouse use. 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.

We bought a house with a 20x20 unfinished greenhouse. Used the triple-wall polycarbonate as the roofing material and liked it so well we're using it on the south-facing wall as well, to help control temperature swings. Read the instructions carefully--twice!!--before installing. But so long as you take care to do it right, this is fantastic material.
Planning to build a lean-to greenhouse/Arizona room, I was very apprehensive regarding what material to work with. My wife and I finally settled on the triple wall polycarbonate and built a great lean-to enclosing about 1000 square feet. She's giddy about all the things she'll be able to do in it and I appreciate the energy savings. When it's 40 to 50 degrees outside during daylight hours, we have to ventilate the up to 112 degree air just to stay inside. The 10 foot panels are lightweight and easy to work with; I attached them to stained redwood studs secured with hurricane straps. The structure easily passed a couple of 50 mph wind tests the first month and should handle 75 to 100 mph without a problem.
