The Haas Door Difference
Polyurethane Foam Construction
The polyurethane foam in a Haas door section is fully enclosed inside the steel skins and is protected from losing its thermal performance. This design puts the insulation properties of polyurethane foam way ahead of polystyrene foam for performance and value.
Polyurethane foam is a two-part system. It begins with two chemical blends that, when mixed together, expand and cure to fill the garage door panel. During the expansion, the foam completely fills the inside of the panel and becomes fully adhered to the steel skins of the door. This forms a composite structure that is of exceptional strength and rigidity. Polyurethane foams are very stable when fully enclosed inside a door section.
Polyurethane foams are used as insulation in garage door panels, roof insulation on commercial buildings, wall insulation in newer high efficiency homes, office chairs, refrigerators, freezers, walk-in coolers, furniture and in automobiles for dashboards, armrests, suspension bushings and other components.
Polystyrene Foam Construction
Polystyrene foam board is used as insulation in garage door panels, in homes as a vapor barrier and as a packing material. This rigid foam board must be attached to or inserted into the door section. Polystyrene board is used on 2400, 2500 and Ribbed Steel models.
