ABSTRACT:
An insulated refrigerator door designed and arranged to enable a flow path for air from the interior of the refrigerator through the door insulation includes an outer door panel of a generally rectangular shape having a surrounding peripheral frame so as to define an interior recessed area, an inner door panel having a plurality of vent holes arranged in two spaced-apart series and an insulation panel disposed between the inner and outer door panels. The insulation panel is configured with a first layer of porous enclosing material, an opposite layer of enclosing material and loose discrete insulation material disposed therebetween. The porous enclosing layer of material is disposed adjacent the inner door panel such that the vent holes of the inner door panel communicate directly with the porous nature of the enclosing layer so as to enable a natural flow of air and moisture from the interior of the refrigerator through the loose, discrete insulation material.
