Energy Efficient Rolling Doors = Money Savings

When you need climate control and security with the compact storage of an overhead coiling door, our Thermiser insulated roller garage door is a perfect choice.  Our overhead coiling doors are manufactured roll formed metal slats, then the double skinned interlocking rolling door slats are filled with chlorofluorocarbon-free (CFC), closed pressure foam to create a high energy efficient exterior door barrier.

Plus, our Thermiser insulated roll up garage doors use a sealing system to prevent air infiltration or air leakage around the perimeter of the door. ASHRAE 90.1 requires an air infiltration rate of less than .4 CFM/FT2 and the 2015 International Energy Conservation Code (IECC) requires air infiltration of less than 1.0 CFM/FT2 for coiling doors at openings that separate with conditioned space from the exterior.

The above calculation is approximate and based on one 12’ x 12’ opening comparing an insulated service door with thermally broken guides and full perimeter seals (that meet the air infiltration requirements of ASHRAE 90.1 and IECC 2015 to the specified product.
