If your insulation has worn down over time, you might notice a spike in your energy bills and drafty rooms in your home. Consult an insulation contractor about spray foam insulation as an effective replacement. This guide breaks down some frequently asked questions about this product so that you know whether it’s a smart choice for your home.

What to Know About Spray Foam Insulation

What is the R-value of spray foam insulation?

R-value indicates the insulating ability of the product per inch. The specific R-value of spray foam insulation depends on the type of insulation you purchase. Open-cell foam insulation has an R-value of about 3.5 per inch, while closed-cell is about 6 per inch. However, there are closed-cell products available with higher R-values. Your insulation contractor can make recommendations based on your budget and climate.

Can foam insulation be exposed?

Spray foam insulation can be exposed in some cases. However, it wears down in sunlight. You can keep it exposed in spaces like attics, but cover the insulation in all living areas of the house or anyplace the sun could reach it.

Does it need a vapor barrier?

Use a vapor barrier if you install spray foam insulation; most municipalities require it by code. In the event of a fire, the barrier prevents the insulation from combusting. Your insurance company may also be more likely to cover related damages if you show that you had a fire barrier. Insulation on its own is not fire-resistant, so have a barrier even if you are not required to have one according to code.

How long does foam insulation last?

When properly installed, most insulation lasts for the duration of the home — often more than 80 years. Factors like water damage, sunlight exposure, and mold can shorten this life span. Hire an experienced insulation contractor to ensure they install it correctly the first time.
