Wayne Dalton Model 6600

Model TS150

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

The Wayne-Dalton Thermospan Series doors are the only doors in the industry with patented, roll-formed integral struts on each  section, making them the most rigid doors available.

Popular in a wide variety of commercial and industrial applications,the Thermospan 150 offers a strong combination of characteristics, including strength,rigidity,longer life and energy efficiency at a highly competitive price.

The Thermospan 150 is manufactured using our patented, continuous foamed-in-place technology, in which the polyurethane core is securely bonded to hot-dipped galvanized  inner and outer skins. This process gives the Thermospan 150 outstanding thermal, strength, and bonding characteristics while creating a door that is significantly more efficient than conventional insulated steel doors. A designed-in joint seal also helps save energy by preventing air filtration. Optional factory glazed windows and aluminum full view panels, combined with two standard finishes (white and brown), help ensure that the Thermospan 150 meets your aesthetic requirements as well.


The Thermospan 150 is designed for easy installation, rugged durability and longer life. Features such as 18-gauge steel end caps and two 13⁄4″ roll-formed struts on each section give the Thermospan 150 increased rigidity, while the factory finished interior and exterior hot-dipped, galvanized skins make installation easier, add life to the door and provide greater durability. The Thermospan 150 also features hardware plates at all fastener points to add durability and extend the life of the door.
