Wayne Dalton Thermospan® Model 200 is a cost-effective door that provides premium thermal efficiency. Continuous foamed-in-place polyurethane insulation and a non-conductive thermal break between the inner and outer skins combine to provide a U-value* of 0.057 and an R-value* of 17.50.
The Wayne Dalton Thermospan® Series doors are the only sectional doors in the industry with patented, roll-formed integral struts on each section, making them the most rigid doors available. The Thermospan® Series also has a patented manufacturing process with a polyurethane core that is continuously foamed-in-place between the outer and inner skins. An innovative thermal break keeps the interior skin at room temperature, preventing condensation and frost and helping to resist corruption.
*Wayne Dalton uses a calculated door section R-value and U-value for insulated doors.
