If you're looking for a superior type of insulation for your home, talk to an insulation contractor about closed-cell spray foam. Spray foam is available in open-cell and closed-cell forms, with closed-cell spray foam offering the best insulation. It can be used in different places throughout your home and even on the roof. Here are some benefits of choosing closed-cell foam when you insulate your home.

Closed-Cell Foam Acts As A Vapor Barrier

The chemical reaction that occurs when spray foam insulation transitions from a liquid to a foam creates small structures in the foam called cells. Some chemical formulations create open cells and others create closed cells.

Closed-cell spray foam insulation is resistant to water and moisture. This eliminates the need for a moisture barrier, and it protects your walls from mold and other moisture-related problems. This water-resistant quality makes closed-cell insulation a good choice for areas that might get wet, such as exterior walls and the attic.

Closed-Cell Spray Foam Has A High R-Value

Closed-cell foam has one of the highest R-values of any type of home insulation, including open-cell foam. The R-value rates how well insulation stops the transfer of heat. High R-value insulation keeps your home cooler in the summer and warmer in the winter, so it helps control your energy bills.

The R-value recommended for your home depends on what climate zone you live in. the R-value can be increased by increasing the thickness of the foam. However, the more foam the installer uses, the more your insulation costs, so the contractor will determine how thick to make the insulation barrier before work begins.

Spray Foam Closes Gaps

Spray foam insulation is a good choice for sealing up your attic or crawl space because the foam expands to seal up cracks and gaps. Closed-cell spray foam doesn't expand as much as open-cell foam, so it can reach in tight places to block as many air leaks as possible.

When insulating your attic or other space, it's important to consider R-value and sealing air leaks. Closed-cell foam is excellent at both. Although closed-cell spray foam insulation costs more than open-cell foam, you'll be getting superior insulation that lasts a long time while also protecting your home from water damage.

An insulation contractor can help you decide if closed-cell insulation is right for your home and where it should be applied to get the most benefit while balancing the cost of insulating your home. Spray foam insulation should be installed by a licensed professional for safety reasons and to ensure the foam is applied properly. Once it's in place, closed-cell foam can last for several decades.
