Evan spraying spray foam insulation in building

We receive many questions about spray foam insulation and its benefits in your home. Many homeowners feel intimidated when it comes to building science and are especially wary of seemingly uncommon solutions like spray foam insulation.  For this issue’s Q & A, we will answer the questions you’re all asking.

What is spray foam insulation?

Spray foam insulation is a spray-applied cellular product created by two materials – isocyanate and polyurethane. When combined, these substances react with each other and magnify in size after its sprayed in place. There are two types of spray foam insulation- open cell and closed cell.

Does it reduce energy usage and costs?

Spray foam is powerful and makes air infiltration and exfiltration a pretty hard feat. Around 40% of a building’s energy is lost due to air escaping from your home.  Spray foam acts as an air barrier, sealing your building envelope from heat exchange. It yields a higher R-value by thickness compared to batt insulation, increasing the energy efficiency of your home and saving families hundreds of dollars on energy expenses every year.

Does it protect against the outdoor elements?

Alongside acting as an air barrier, spray foam insulation also acts as a moisture barrier and prevents water from seeping into your home. It also protects your home against mold and mildew damage. Not only does spray foam protect your home against the outdoor elements, it also deters pests and those furry little friends that you want to keep outside.

Does it add rigidity to your home?

Spray foam insulation does not break down over time and can help support the overall structure of your home, contingent on the application and thickness you use. It prolongs the life of your foundation and walls to make your home long-lasting and structurally resilient.  Just keep in mind that removing spray foam that is already in place can be a very laborious task.

Does it protect against outdoor pollutants?

Many illnesses, including allergies and asthma, worsen by outdoor pollutants and contaminants. We use spray foam to create a near air-tight building envelope and seal up every hole in the home. Creating this air barrier prevents unwanted outdoor air quality from entering.
