Air can seep indoors through gaps around your windows and doors, leading to drafty spots in your home. However, you can prevent this unwanted infiltration with spray foam insulation. This powerful sealant fills in fissures and provides air-tight barriers. Here are some of the most common products that you can use for your home.

A Guide to Different Kinds of Spray Foam Insulation

High-Density Insulation

This type is generally used around roofs and other exterior structures. High-density spray foam insulation has a thicker texture and can be applied in large, expansive widths. Once in place, the foam creates a safeguard against water and air leaks. Its thermal-resistant material also maximizes interior air distribution throughout the home by keeping outdoor air away. Construction companies will typically use high-density insulation to provide a barrier against strong winds. 

Medium-Density Insulation

Unvented attics, wall cavities, and crawl spaces are a few spots where medium-density spray foam insulation is applied. Its tensile strength allows the material to endure stress. The foam can also stick to surfaces so that air, water, vapor, and noises can’t infiltrate. If the insulation is closed-cell foam, commercial and residential builders may use it for reinforcing ceiling and wall support.

Low-Density Insulation

From roof decks to crawl spaces, low-density foam can be applied in various areas. The insulation, which is also known as open-cell foam, is primarily used as an air barrier. The material has a soft and flexible texture that absorbs sound and provides heat insulation around windows and doors. Low-density foam offers enough flexibility to adjust but remain intact when buildings contract and expand due to temperature changes.
