Energy efficiency is becoming increasingly important. High thermal insulation leads to lower energy costs. Our narrow stile doors offers an excellent U-value, which minimizes heat and energy loss. The lower the U-factor, the better the door keeps in heat.

Ellison’s narrow stile door includes our 1” wide vertical stiles, a squared 4 ¾” high top rail, a squared 10” high bottom rail (following ADA guidelines) creating an exceptional thermal performance while maintaining the craftsmanship and quality of an Ellison Bronze door.

Testing was done with a 960mm x 2090mm (38in. x 82in.) single doors leaf. The material tested was a painted, non-thermally broken aluminum door with mohair weatherstripping AND also, a Stainless Steel door with mohair weatherstripping.
