Spray foam insulation is a superior alternative to traditionally used insulation materials such as rock wool, fiberglass, cellulose and polystyrene boards. Two materials, isocyanate and polyol resin, are gently heated and come together at the tip of a spray gun to form an expanding foam that is applied onto a specific area. This liquid then quickly transforms into thick, hard foam insulation. It guards against heat loss, wood rot, mold and dampness, does not degrade or break down and lasts a lifetime.
In the home, it can be used to insulate attics, roofs, floors, interior and exterior walls. Other applications that will benefit from spray foam include boats, shipping containers, sheds, agricultural buildings, and within the industrial/commercial sectors.
New home spray foam insulation
Spray foam insulation is available in two different types. Open cell and closed cell.
Open cell spray foam contain a network of small air pockets that are minutely connected to each other. This traps warm air and inhibits the loss of heat from your home. It is breathable however, which allows the moisture in a house to pass through, eliminating damp conditions.
Closed cell foam insulation is much more dense than the open cell variety. It has a smaller, more compact air pocket structure which are not connected to each other. It is a superb air barrier as well as a water vapor barrier by creating an envelope within the building. It is commonly used on roofs, sheds, exterior walls, within agricultural structures and other outdoor applications.
