Designed with energy efficiency in mind, the insulator door has a dual flap system intended to create a pocket of dead air space in order to maximize the insulation value of the door. A magnetic seal across the flap width, plus another magnetic seal on both sides of each flap insures a nice, tight, weatherproof closure. The frame itself is constructed with aluminum and corner plastic pieces. A plastic security panel can be dropped into place in order to block off access.
Features:
Fits doors ranging in thickness from 1 3/8" to 2"
Dual flap system for greater weather protection than a single flap door
