Spray foam insulation is a relatively new plastic material, with an R-values that is almost doubles of traditional insulation materials such as fiberglass batts/rolls. Most spray foam insulation is made of liquid polyurethane or polystyrene which is also found in small aerosol cans and used in refrigerators and water heaters. Polyurethane Foam is indeed experimenting a growing popularity, due to its effectiveness (polyurethane foam has a R-value of 6.7 to 7 – 1 inch thickness which is approximately the double of common insulating materials). Spray foam insulation is an excellent alternative to traditional insulation materials due to several reasons which we are going to talk about below.

Spray foam insulation is ideally applicable to home cathedral ceilings, side walls and basement walls. It is excellent for filling small house spaces such as window jambs, rim joist areas, small stud bays, and other penetrations where traditional insulation materials (fiberglass batt insulation) are difficult to reach.

Spray foam insulation works by pumping the liquid through a pressurized spray nozzles onto surface of cathedral ceiling or sidewalls and basement walls, forming a continuous insulating barrier. After being applied, the material expands and conforms to the shape of the cavities, filling and sealing them thoroughly.

Spray foam insulation is mostly intended for indoor use only. But it will stand up to weather changes and adds to the structural and thermal ability of the structure. Spray foam insulation will not shrink in changing weather and it is also flexible enough to allow the other building materials the room to react to changing weather conditions.

Installation for spray foam insulation should be done by an experienced installer. It demands special equipment and requires skill and knowing to spray the materials into cavities.  Therefore , you shouldn’t try installing spray foam insulation by yourself unless you know what you are doing.

In short, spray foam insulation is an excellent alternative to other conventional insulation methods. If you were thinking about applying an insulation to your new home, do consider spray foam insulation.
