Cornell Thermiser® Insulated Rolling Door ESD20

Cornell Thermiser® Insulated Rolling Door ESD20


Thermiser Insulated Rolling Doors, designed for exterior use, help maintain different temperatures on each side of the door. They are an ideal choice for use in environments that require climate control, security and durability: distribution, industrial, hospitality, retail and more.

Thermiser doors store compactly, require little to no maintenance and deliver a low life cycle cost. In fact, we warranty this product for 50,000 cycles as standard.

Foamed in place insulation offers superior protection against the elements, improved security and reduced sound transmission. The Thermiser helps seal the building envelope and keeps noise in – or out.

Sound Transmission Class (STC) rating is up to 30 for the curtain and up to 18 for the entire assembly. If an STC of 32 is desired, additional options are required. Please consult the factory for details. All configurations are evaluated per ASTM E90, based on testing a complete, operable assembly.

If you are interested in an insulated door that is configured to withstand an operational windload of 20 PSF, please check out our Wind-Master Door.
