Spray foam insulation starts off as a liquid and is applied by a specialized spray gun that combines two chemicals (isocyanate and polyol resin, usually). When the spray meets the surface it reacts and expands to multiple times its original volume. The foam fills in any gaps and crevices and dries to form an effective air and vapor barrier.

The foam also creates pockets that insulate the space and prevent heat energy from escaping or getting into the home or building. This makes it one of the most effective types of insulation. Find out 316insulationservices.com

Spray foam is an ideal option for new construction, pole barns and commercial structures. However, it can be used in existing homes as well to increase the R-value and make the building more comfortable. The foam is durable and can be installed over existing drywall or other surfaces.

It is also less likely to promote mold or mildew than other types of insulation because it does not trap moisture in the building envelope. However, a proper air and vapor retarder system should be employed to reduce condensation.

Choosing the right type of foam and hiring a professional are the keys to maximizing the benefits of spray foam insulation. Closed cell spray foam is the better choice because it is physically stronger and provides a more effective vapor barrier than open-cell spray foam. It is more expensive than open-cell, but the extra performance is worth the investment for many homeowners.
