ThermaGlas® SLT is engineered for use on enclosures where plant materials must thrive, and where people must feel comfortable.  Examples of such structures include retail garden centers and commercial greenhouse packing sheds or holding facilities.


ThermaGlas SLT features Selective Light Transmission resin technology that is designed to absorb the sun’s harmful UV rays, transmit the beneficial wavelengths plants use for growth, and reflect some of the heat-giving infrared wavelengths.  The result is high quality light with less stress-inducing heat from the sun. 


ThermGlas SLT polycarbonate sheets offer all the benefits of polycarbonate glazing, such as high impact resistance, excellent durability, and 99.9% UV blocking.


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