Enhancing the insulation of your house is one of the best ways to boost your home’s thermal performance and energy efficiency. It will also help decrease the carbon footprint and expenses for your monthly energy costs.

One example of insulating your house is to use spray foam insulation. It’s a good insulation choice because of its perks, such as providing constant humidity inside the house by preventing temperature fluctuations, creating an air-tight seal that keeps your house comfortable and warm, and protects against elements.

It also helps reduce indoor allergens or other pollutants, such as mildew, mold, dust, or mold.

What is Spray Foam Insulation? 

Spray foam (SPF) is an insulation material made by mixing two main chemicals: polyol resin and isocyanate. The two chemical ingredients undergo a reaction when combined, producing a foam that expands quickly when sprayed. The spray foam created is commonly used as insulation without air filtration.

It can expand up to 30% when applied, which helps fill even the smallest gaps, cracks, or even the hard-to-reach areas. The spray foam also hardens quickly upon application.

Spray Foam Insulation has two available types: Medium-Density Closed-Cell Spray Foam (ccSPF) and Light-Density Open-Cell Spray Foam (ocSPF).

Medium-Density Closed-Cell Spray Foam is known for being rigid and dense and having each air cell sealed completely. It measures about 1.75 — 2.25 lbs./ft3 and it also has a higher R-value or thermal resistance, which ranges from five to six per inch.

Closed-cell spray foam acts as a barrier to vapor, heat, and air transfer and helps prevent mildew and mold, which makes this type of spray foam an excellent choice for exposed areas. It also resists moisture from passing through and helps protect surfaces from wear and tear. 

Light-density Open-Cell Spray Foam, also known as half-pound foam, is semi-rigid with a sponge-like appearance that retains its shape well. It has an R-value or thermal resistance that ranges about 3.8 per inch.

Once installed, open-cell spray foam can expand up to 100 times its size enough to fill crevices, cracks, even uneven surfaces. It also creates an air seal filled with carbon dioxide that enhances insulation.

Unlike closed-cell spray foam, open-cell spray foam doesn’t act as a barrier for air or vapor though it can reduce the sound frequency by blocking and helps absorb air leakage.
