The Thermiser Max Low U Insulated Rolling Door by Clopay Corporation has a U-factor rating of 0.532, making the door highly energy efficient. A CPVC backer creates a thermal break in the curtain assembly and lowers the thermal transfer rate compared to metal-on-metal joint assemblies. The Thermiser Max is ideal for exterior applications where climate control and energy efficiency are critical, like warehouses and equipment storage facilities.
The door has been third-party tested per DASMA-105 and is ASTM E84 rated. It also has a Sound Transmission Rating (STC) of up to 27 for the full assembly and meets ASHRAE 90.12, IECC 2021, and California Title 24 air infiltration requirements with an independently tested value of < 0.3 CFM per square foot.
