Insulated Fire Door

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)
