The Thermospan® Series insulated 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 corrosion. Suitable for medium and heavy duty commercial and industrial applications, the Thermospan® series provides strength and durability coupled with thermal efficiency.
