Wayne-Dalton’s Thermospan® 200-20 offers premium thermal efficiency combined with a heavy-duty, 20-gauge flush exterior surface. Featuring continuous foamed-in-place insulation and a non-conductive thermal break between the inner and outer skins, the Thermospan 200-20 provides a U-value of .057 and an R-value of 17.50, making it the ideal door for energy-conscious architects, engineers, contractors and building owners.
The Wayne-Dalton Thermospan Series doors are the only ones in the industry with patented, roll-formed integral struts on each section, making them the most rigid doors available.
The Thermospan 200-20 outperforms other conventional insulated steel doors in the area of energy efficiency. The Thermospan 200-20 offers a U-Value of .057 (R-value of 17.5) — a dramatic improvement over most conventional insulated steel doors, which typically have R-values between 5 and 8. At the heart of the Thermospan 200-20’s excellent insulation qualities is a patented manufacturing process during which the polyurethane core is continuously foamed-in-place between the outer and inner skins, forming a homogenous sandwich of steel/polyurethane/steel. This process creates outstanding thermal, strength and bonding characteristics which combine to make the Thermospan 200-20 an ideal choice for commercial and industrial applications. Additionally, a non-conductive thermal break virtually stops hot or cold outside temperatures from being transmitted to the inside.
