Wayne Dalton’s Thermospan® Model 150 polyurethane-insulated, sectional steel door provides excellent thermal efficiency. Featuring an R-value* of 14.16 (U-value* of .0706), the Thermospan® Model 150 is an excellent value when thermal efficiency is important, but strength, rigidity and durability can’t be compromised.
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.
