When it comes to insulating your home or building new, there is no better solution than spray foam insulation. It seals the air barrier in your building envelope to prevent heat and cold loss and save on your energy costs each month. It also reduces noise penetration by up to 80% and makes your home healthier, quieter, and more comfortable for you and your family.

Spray foam insulation is made of 2 types of composite materials, polyurethane and isocyanate that are sprayed from a specialized gun. The chemicals react and expand instantly to provide a tight fit in the wall or cavity of your home. The product can also be sprayed in attics, basements, crawl spaces, overhangs (or cantilevers), knee walls, and bonus rooms.

The Science Behind Spray Foam Insulation: How It Works and Why It’s Effective

During the spraying and curing process, the insulation off-gases volatile organic compounds or VOCs that can cause respiratory problems in some people, especially children and elderly individuals. It is recommended that homeowners vacate their homes during this process and stay away until the chemicals have had a chance to clear the area.

It is important to work with a licensed and certified spray foam insulation professional for the best results. They will ensure that the right amount of foam is applied and that it dries at the correct temperature to produce optimal results. They can also provide advice on the best place to install the product so that you get the most from its benefits.

Most professionals use closed cell spray foam that is water resistant and acts as a thermal, air and vapor barrier. This product offers a higher R-value and more structural support than open cell foam. Many manufacturers are transitioning to low global warming potential blowing agents as well. A few examples include Ecomate and HandiFoam High Density, both which are made with a hydrofluoroolefin blowing agent that has a much lower GWP than HFC-based products.
