ABSTRACT:
A novel door jamb having an isolated heat strip in which the surface to be contacted by the door is made of a re-enforced fiberglass material which has high impact resistance, superior chemical and corrosion resistance, will not easily scratch, and can be readily repaired. Secured to the fiberglass section of the door jamb is an isolated heat strip material requiring a low wattage, which functions to keep the door gasket pliable allowing it to seal tightly to the jamb and thus eliminate any chance of frost buildup on the jamb due to outside air leakage by the gasket.
