Spray foam insulation is a revolutionary new type of insulation that provides far better energy results than traditional fiberglass batts, by combining an excellent R-Value with superior air sealing to create a tight building envelope. The result is lower heating and cooling costs; more balanced HVAC performance; and enhanced indoor comfort season to season.

The unique liquid components in spray foam insulation react rapidly when mixed together at the tip of a specialized spray gun, and expand to fill in holes, cracks and gaps in wall cavities, exterior walls, attics, and crawl spaces. The spray foam also forms an air, moisture and vapor barrier to limit air infiltration and loss that causes high energy bills.

Closed cell spray polyurethane foam insulation has smaller pockets within its structure, and is often more effective in resisting air movement as well as reducing sound transmission. The closed cells prevent water vapor transfer and are resistant to mold growth, rodents and other pests.

Whether open or closed-cell, both kinds of spray foam insulation can effectively stop convective heat flow from hot areas to cool ones and vice versa. They are a great way to increase the R-value of your existing attic or roof, and reduce the amount of heat that is transferred through the ceiling and into the home during colder weather.

Spray foam insulation should be applied by a professional contractor because it requires specialized equipment and training to get the best results. This is usually more expensive than a DIY approach, but is well worth it in the long run, for both homeowners and builders.
