Triple wall structure is ideal for harsh climates where superior strength and heat retention is desired.

ThermaGlas Multi-wall Polycarbonate Sheet is designed and engineered specifically for commercial greenhouse use. ThermaGlas products are available in 4-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.

Sunroom Roofing

I've been in the construction and building business most of my life and this is the first time I've used 16mm polycarbonate roofing. The ease of installation was really nice to do by myself and on a stepladder. I would recommend this product to anyone for durability and use for sunroom roofing.

Its worth the money

I recently bought the 16mm triple wall poly. I live at 6000 ft elevation and We get very cold here. I decided to buy the 16 mm instead of the 8 mm poly. It is worth the extra money. We had -22 below zero for about 5 days and the green house kept from freezing. The day time temps reached from 95 to 105 degrees.

The Ferrari of Greenhouse Panels

This was my first greenhouse - an earth-sheltered low-profile structure off the back of my raised garden. These panels lived up to their promise. They are durable enough to have withstood a foot of snow and 40mph winds so far, but much more impressive is the fact that combined with passive-solar heating techniques, they have enabled me to completely eliminate active heating in a Montana winter. They insulate so well (and allow enough light through to heat my water barrels at the same time) that I have been through several nights of -10F to -20F and the greenhouse temp has still remained in the mid 30s with no heaters whatsoever! The panels are expensive, but if you are looking for the ultimate efficiency and durability, this is the way to go.
