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. This offers superior protection against the elements, improved security and reduced sound transmission – both outside your building, sealing the building envelope, and inside.

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 22 for the entire assembly, as tested per ASTM E90 (with a complete, operable assembly)
