Insulated Sectional Steel Door

Ideal for applications where thermal efficiency is important, and competitive cost is essential, Wayne Dalton’s Thermospan^® Model 125 sectional door features a foamed-in-place polyurethane core and standard joint seal that provides a substantially higher thermal efficiency than industry standard polystyrene insulated doors, making Thermospan^® Model 125 suitable for commercial and industrial applications.

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.
