Energy Efficient Insulated Rolling Doors

Our Thermiser Max® Insulated Rolling Door is today’s most energy efficient rolling door.

Built to order, our Thermiser Max® insulated door is tested and proven to perform best in exterior openings where maintaining environmental separation on each side of the door is necessary. Our Thermiser Max® Insulated Doors meet ASHRAE® 90.12, 2021 IECC® and California’s Title 24 air infiltration requirements with an independently tested value of less than 0.3 CFM/FT2 .

Our exclusive full perimeter door sealing system, combined with thermally broken guide construction and insulated curtains, minimizes air infiltration and thermal transference.

A green, energy efficient, thermally insulated roll up door that delivers a 94% decrease in air infiltration compared to standard products and can contribute to green building ratings. Because we care about the environment as much as you do, this overhead insulated door can help you achieve up to 38 points in five LEED certification credit categories.

Our commercial insulated door sealing system not only significantly reduces air infiltration but also reduces sound transmission. Sound Transmission Class (STC) rating is up to 30 for the entire assembly. If an STC of 32 is desired, additional options are required. Please consult the factory for details. All configurations are evaluated per ASTM E90, based on testing a complete, operable assembly.
