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. 16mm Triple Wall Superb thermal insulation - saves energy Impact resistance - virtually unbreakable Light weight Weather and UV resistant Low flammability (available with CC1 rating) Easy to work with and install using ordinary tools Rigid, yet capable of cold-forming to an arch Wide service temperature range 10-year limited warranty Can be easily cut in any pattern using a circular saw with a fine tooth blade 76% light transmission Approximate Weight: 16mm = .55 lbs per sq. ft.
