Thermally Broken Steel Doors

Thermally Broken Steel Doors

Clark Hall offers steel doors appropriate for northern climates that experience very low temperatures and severe changes in daily temperatures. There are several components to the design of this type of door:

•    Fully insulated door jambs (frames), stiles, rails and panels

•    Thermal breaks between the interior and exterior sides of the jambs, stiles, rails and panels using a rigid Ultra High Molecular Weight Polyethylene (UHMWPE)

•    Insulated Low-e glass options for specific conditions

•    Compression weather-stripping between the jamb and the door

• Weather-stripping on all operable windows

These doors must be installed with insulation between the door frames and framing of the home. This can be done with spray or traditional insulation material.
The combination of the door components and insulation during the installation make the door system appropriate for northern climates supported by Clark Hall's Warranty.
