 "Insulated Sectional Steel Doors" Thermospan® 150 gives you competitively priced, thermally efficient doors with remarkable insulation values surpassed only by our Thermospan® 200 Model. When you combine this outstanding energy efficiency with an attractive white or brown flush exterior surface, high-strength steel and quiet, smooth operation, you will be glad you chose Thermospan® 150. Standard sizes available up to 26' wide and 20' high. |

Insulation materials placed between two metal surfaces without a thermal break greatly reduce the effectiveness of the insulation. Generally, the outer surface of conventional steel doors wraps around and becomes a part of the inner door surface. The process used to make Thermospan®150 is different. It begins with two separate skins: one for the inner and another for outer surfaces. These skins are separated along each edge of each section by a thermoplastic material that effectively breaks any contact between inner and outer skins. To assure thermal integrity, seals between all section joints are factory-installed, as are vinyl “bulb” astragals which prevent air infiltration between floor and bottom of doors. Because of these features, an excellent “U”-value of 0.0706 is achieved. Testing on a conventional |

| Two integral (1-3/4" deep) struts are roll-formed into the back skin (inside surface) of each section of Thermospan® 150. This often eliminates the need for externally fixed stiffeners which are often used on the inside of conventional doors. And when Thermospan® 150’s cavity is filled with polyurethane, the struts are filled as well, making for an extremely strong, yet lighter weight door. |

A Thermospan® 150 door is virtually maintenance-free. If damage occurs – or if other than routine maintenance is required – inside face hardware, tracks and springs are standard parts used industry-wide. This means they’re readily available and generally are stocked by most independent commercial/industrial door distributors. Also, with Thermospan® 150, heavy-duty, hot-dipped galvanized hinges and tracks are standard. Both the interior and exterior skins of hot-dipped galvanized steel are factory finished with baked on primer and polyester finish coats. Thanks to the thermal break and joint seal, the inside surface of the door remains close to room temperature, eliminates condensation (and/or frost) which may lead to corrosion of inside face hardware. |
