In recent years, spray foam insulation has swiftly emerged as the go-to solution for insulating problematic places that older approaches have failed to adequately handle. Areas where access is restricted, such as the joist end or the rim-joist; smaller surface regions; and areas where numerous tie-ins are necessary, such as frost walls, are examples of such situations.
Due to concerns about vapor barriers in attics, the restoration and new construction markets are increasingly turning to 2 pound closed cell insulation for protection. When applied to the attic floor, a 2′′ minimum coating of 2 pound spray foam may be used to seal all penetrations and create a better vapor barrier over standard polyurethane.
Spray Foam insulation is divided into two groups, each of which has its own set of advantages. Because of its expansion qualities, open cell foam, also known as half-pound foam, is simpler to spray into small places. It also offers higher soundproofing properties and is more cost efficient. Closed Cell foam, also known as two-pound foam, has a higher R-value per depth inch and may act as a vapor barrier when applied to a depth of at least 2 inches.
