Abstract
An insulation assembly for a forced gas unit comprises a facing layer and a porous insulation layer joined together by an adhesive. The facing layer includes pressure-balancing and non-pressure-balancing regions. Perforations are formed in the facing layer after the facing layer and the insulation layer are joined together and after the adhesive is cured. The perforations allow gas to flow through the facing layer so as to adequately balance the static pressures acting on the exposed and non-exposed surfaces of the facing layer.
Claims13
An insulation assembly for a forced gas unit comprising:
- an insulation layer;
- a facing layer including at least one non-pressure-balancing region having no perforations formed therein and a pressure-balancing region having perforations formed in said facing layer;
- and
- an adhesive attaching said facing layer and said insulation layer to each other, wherein said at least one non-pressure-balancing region is substantially impervious to the passage of gas and said perforations are substantially void of said adhesive to allow gas flow through said facing layer.
A forced gas unit comprising:
- a housing including interconnected panels;
- a blower disposed in said housing;
- and
- an insulation assembly attached to an inner surface of said housing, said insulation assembly comprising:
- an insulation layer;
- a facing layer including at least one non-pressure-balancing region having no perforations formed therein and a pressure-balancing region having perforations formed in said facing layer;
- and
- an adhesive attaching said facing layer and said insulation layer to each other, wherein said at least one non-pressure-balancing region is substantially impervious to the passage of gas and said perforations are substantially void of said adhesive to allow gas flow through said facing layer.
