Cornell's energy-efficient Thermiser® Insulated Rolling Doors combines the robustness of a rolling steel door with foamed in place insulation. This offers superior protection against the elements, improved security and reduced sound transmission – both outside your building, sealing the building envelope, and inside.

These 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.

The doors are constructed for daily use and can withstand operation of up to 20 cycles per day – that’s 50,000 cycles for the lifetime of the door. If your requirements call for more than 20 cycles per day, or 50,000 cycles lifetime, check out our High Performance Doors

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

• Climate Control : Cornell's advanced full-perimeter seal and insulated curtains provide impressive reductions in air infiltration and thermal transference.
• Security : The 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)

The Thermiser Max® Insulated Rolling Door is the most energy-efficient insulated rolling door available today, with the certifications to prove it. This door has it all while decreasing air infiltration by 94% versus standard products, and can help you achieve up to 38 points in five LEED certification credit categories.

Thermiser Max Insulated Rolling Doors meet ASHRAE ® 90.1 and IECC® (International Energy Conservation Code) 2015 Section C402.5.2 Air Infiltration requirements with an independently tested value of less than .3 CFM/FT2.

The doors provide all the benefits of the standard rolling door offering, plus :

• Climate Control : Cornell's exclusive patent-pending sealing system, *(with thermally broken guide assemblies and a lintel seal), together with the insulated curtain, provides impressive reductions in air infiltration and thermal transference.
• Security : The 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 32 for the entire assembly, as tested per ASTM E90 (with a complete, operable assembly).

These doors are constructed for daily use and can withstand operation of up to 20 cycles per day – that’s 50,000 cycles for the lifetime of the door. If your requirements call for more than 20 cycles per day, or 50,000 cycles lifetime, check out the High Performance Doors.
