Insulated Roll Up Door

Thermiser Insulated Rolling Doors, designed for exterior use, help maintain different temperatures on each side of the door. These insulated rolling doors 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 insulated rolling door helps seal the building envelope and keeps noise in - or out.

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
