Insulated Sectional Steel Doors Cut Your Total Cost

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.

Materials & Construction

The Thermospan 200-20 also features two patented 1 3/4″ integral roll-formed struts per section providing the highest strength-to-weight ratio. Part of what makes the Thermospan 200-20 virtually maintenance free is the pre-painted flush exterior surface. This outer skin of hot-dipped galvanized, structural quality steel is factory finished with baked-on corrosion-resistant primer and a white polyester finish coat. The inner skin is also hot-dipped galvanized steel factory finished with the same corrosion-resistant primer and polyester finish coat.

The Thermospan 200-20 features an innovative thermal break that keeps the interior skin at room temperature, preventing condensation and frost and thereby resisting corrosion. A flexible vinyl bulb seal and non-corrosive polymer retainer prevent water and air filtration at the bottom of the door. Reinforcement plates are located at all hardware attachment locations, and industry standard commercial-grade, heavy-duty, hot-dipped galvanized hardware also contribute to the Thermospan 200-20’s long service life.
