What is Spray Foam Insulation?

There are a lot of misconceptions about spray foam insulation - but what is spray foam insulation?

We will cover the basics of spray foam insulation in an effort to give you a better understanding of it and explain why it is the best insulation for you.

Spray foam insulation has a higher R-value than other commercially available forms of insulation. For example, our closed cell spray foam insulation has an R-value of approximately R-6.5, whereas fiberglass has an R-value of anywhere between R-2.2 and R-4.3. 

An R-value is a measure of resistance to the flow of heat. The higher an R-value is, the more it resists the flow of heat. This makes it a better form of insulation.

Spray foam insulation expands to fit the environment, which ensures there is an airtight seal. This airtight seal is what makes spray foam insulation a much better alternative to conventional forms of insulation.

There are two types of spray foam insulation. Open cell, and closed cell.

As the name would suggest, open cell spray foam insulation has open pores within the foam. It is softer to the touch, and is great at dampening sound. Closed cell spray foam insulation is much harder, but is impermeable to moisture. 

You can read our comprehensive comparison between open and closed cell spray foam insulation here.

Conventional forms of insulation such as fiberglass and cellulose insulation do not guarantee an airtight seal. They are also easily damage by moisture. 

We recommend spray foam insulation as it pays for itself in no time. You can find a full list of benefits here.
