A new home improvement project might seem like a lot of money at first, especially for high-end insulation like spray foam. However, this type of insulation project should always be seen as a long-term investment. Spray foam keeps your home safe, saves energy, and will more than pay for itself over time.
Here’s a breakdown of how much it could cost to install it and why it’ll help you save.
Is Spray Foam Insulation Expensive?
Yes, spray foam insulation costs more than traditional options like batt fiberglass or cellulose. However, the final cost depends on many individual factors of your project, such as:
- House size
- Insulation thickness
- Open-cell vs closed-cell foam
- Location
- Labor costs
On average, homeowners pay anywhere between $1,453 and $4,333. Open-cell spray foam costs between $0.60 and $1.60 per board foot, while closed-cell spray goes for $1.30 to $3.10 per board foot. Every project is different, so always talk to an insulation expert to get a better idea of how much you’d need to pay.

How Spray Foam Insulation Leads To Better Savings
You’ll Save On Energy Bills
Spray foam is top-tier when it comes to energy savings. Its dense material makes it ideal for sealing air leaks, which is one of the main reasons rooms feel colder in winter and warmer in summer. As a result, you can save up to 50% on your energy bills each month. This can add up to thousands of dollars over several years.
It Has A Really Long Lifespan
Spray foam has an exceptionally long lifespan. However, the overall lifespan depends on the type. Closed-cell foam can last up to 50 years, while open-cell foam can last 20 to 30 years before you need to replace it. While the cost may be higher, you can go decades without replacing it compared to other types of insulation.
Higher Home Value and Comfort
A growing number of homeowners are looking for more energy-efficient spaces. Spray foam insulation delivers that by filling all major air gaps, even in hard-to-reach areas. This feature makes it far more attractive to buyers and even boosts its resale value when you decide to put it on the market.
Less HVAC Usage
If you’re in a poorly insulated home, you’re probably stuck using your HVAC system most of the day. Spray foam insulation adds the protection your home needs to keep the hot or cold air out during extreme weather. This means using your heating and cooling systems much less while maintaining a stable temperature.
