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.
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.
