THERMISER® Insulated Roll Up Door


Insulated Roll Up Door

Our energy-efficient Thermiser® Insulated Rolling Doors combines the robustness of a rolling steel door with foamed in place insulation.  Two layers of formed steel combined with foamed in insulation make the Thermiser® overhead door one of the most secure rolling doors available.

Insulation is just the first step in environmental control. If cold or warm air can escape around the door, it is not doing the complete job. Our Thermiser® insulated doors also have our panted door perimeter sealing system, providing a full barrier against the elements.

Not only does this offers superior protection against the elements, improved security and reduced sound transmission – both outside your building, sealing the building envelope, and inside.

Just like any Cookson roll up door, our insulated doors are all custom manufactured to your specifications. With multiple options in overhead door materials, finishes, operators and more, the Thermiser® insulated roll up door is not only a top choice but can meet any need our solution you have.

Our Thermiser Insulated Rolling Doors are designed for exterior openings where maintaining different temperatures, (also known as environmental separation) on each side of the door is necessary and/or desirable.  The full perimeter seal of these energy-efficient doors also reduces sound transmission compared to non-insulated rolling doors.

Thermiser doors provide all the benefits of our standard rolling doors, plus:

  • Climate Control:  Our advanced full-perimeter seal and insulated curtains provide impressive reductions in air infiltration and thermal transference
  • Security:  Our insulated curtain design features two layers of metal with foam in between, making the door stronger and more secure
  • Sound Reduction: The Sound Transmission Class (STC) rating is up to 30 for the curtain and up to 18 for the entire assembly, as tested per ASTM E90 (with a complete, operable assembly).
