Rigid polyurethane foams are used as insulation in buildings, on roofs, water heaters, refrigerated transport, and commercial and residential refrigeration where their insulation value, high strength, moisture resistance and durability are required. Polyurethane foams are also used for flotation, packaging, furniture, adhesives, architectural design, and cavity filling.
Polyurethane foams can be sprayed, poured, or injected into molds using special equipment. Polyurethane foams can also be mixed by hand and poured into cavities.
The major application for Sprayed Polyurethane Foam is in the construction industry as a commercial roofing system and building envelope insulation material, but many home owners are discovering the advantages of SPF systems over traditional fiberglass and cellulose insulation systems. The application of Earthane in a stud wall cavity dramatically increases the structural rigidity, moisture and thermal performance of the construction system.
Earthane is produced by a chemical reaction when two liquid components are combined, an isocyanate, known as the "A" component, and a polyol resin, known as the "B" component. When the two liquids are mixed together, Earthane expands to 20 to 30 times its liquid state. Earthane uses water for this reaction instead of fluorocarbon or other chemical blowing agents. Once cured it solidifies and becomes polyurethane foam.
