8 Benefits of Spray Foam Insulation

Cully and I have experience with many common insulation products. The benefits of spray foam insulation can’t be beat. We’ve installed cellulose, fiberglass, and even removed three 4×8 trailer loads of sawdust insulation from our home’s walls (spoiler alert – that was NOT fun).

But our favorite product, by far, is spray foam insulation. We chose spray foam insulation for our tiny houses and for the ceiling of our recent garage conversion and absolutely love the results.

We all love our homes. We work hard to make sure they’re comfortable and stylish, and we take pride in them. But insulation is one area that often gets overlooked. The right kind of insulation can make a huge difference to your home, and the benefits of spray foam insulation are worth the money, time and effort.

The Eight Benefits of Spray Foam Insulation:

  1. Less Energy Consumption
  2. It Fills Gaps and Stops Drafts
  3. Improved Comfort
  4. Reduce Noise Pollution
  5. Protection from Pests
  6. Improved Indoor Air Quality
  7. Prevents Mold
  8. Long Lasting

Less Energy Consumption

One of the most important benefits of spray foam insulation is that it helps reduce your energy consumption. By keeping your home better insulated, you won’t have to run your furnace or air conditioner as much, which will save you money on your utility bills.

It Fills Gaps and Stops Drafts

Other kinds of insulation can leave gaps and cracks that let heat escape or allow pests into your home. But spray foam molds itself to the shape of your walls and fills those gaps completely. And, no more cold spots in your home! Spray foam insulation blocks drafts and keeps the heat where you want it – inside your house. 

Improved Comfort

Spray foam insulation provides a barrier against both hot and cold air, making your home more comfortable year-round. In the winter, you’ll stay warmer because heat won’t be able to escape through cracks in the walls or around doors and windows. And in the summer, you’ll stay cooler because heat won’t be able to seep in. 

Reduced Noise Pollution

Another benefit of spray foam insulation is that it can help reduce noise pollution. If you live in a city or near a busy road, the foam will help muffle outside noise so you can enjoy some peace and quiet inside your home. 

Protection from Pests

Because spray foam expands to fill any cracks or gaps, it can help seal out pests like mice, bugs, and snakes. If you’re worried about pests getting into your home, spray foam insulation is a great way to deter them. 

Improved Indoor Air Quality

One of the lesser-known benefits of spray foam insulation is that it can improve indoor air quality by sealing out pollutants like dust, mold spores, and pollen. If you or someone in your family suffers from allergies or asthma, this can be a huge relief.

It Prevents Mold 

Because it’s water-resistant, spray foam stops moisture buildup that can lead to mold growth.

Long-Term Savings

The benefits of spray foam insulation far exceed the higher price point. And over time, the savings you’ll enjoy on your utility bills will more than make up for the initial cost difference.

Benefits of Spray Foam Insulation: Is it worth the cost?

When it comes to insulation, you generally get what you pay for. The higher the initial investment, the higher the R-value and the longer the lifespan. So when it comes to choosing spray foam insulation, the initial higher costs are actually a good thing in the long run. Here’s why:

Higher R-Value Means More Energy Savings

The whole point of insulation is to save on energy costs, right? The higher the R-value of your insulation, the better it will be at doing its job. Spray foam insulation has one of the highest R-values of any type of insulation on the market today. That means it will do a better job of keeping your home insulated and save you money on your energy bills.

Longer Lifespan Means More Value For Your Money

While spray foam insulation does have a higher initial investment than other types of insulation, it also has a much longer lifespan. This means that you’ll get more value for your money in the long run with spray foam than with other types of insulation. In fact, spray foam insulation can last up to 50 years with proper maintenance, while other types of insulation may only last 10-15 years. 

Better Air Quality Means Better Health For Your Family

Another benefit of spray foam insulation is that it helps to improve air quality in your home. By sealing up cracks and gaps in your walls and ceilings, spray foam prevents outside air from coming into your home and circulating through your HVAC system. This can help to reduce allergies and asthma symptoms for your family and make your home a healthier place to live. 

Cons of Spray Foam Insulation

Now, before you bust out the credit card to buy a heavy-duty spray foam insulation kit, you might want to consider some of the cons of this home improvement project. Don’t get me wrong, we’re all for making your home as comfortable and efficient as possible. But sometimes, spray foam insulation is not the best option. Here are three reasons why:

It’s Messy

There’s no getting around it, spray foam insulation is messy. And we’re not just talking about the little bits of overspray that end up on your floors and furniture. We’re talking about the fact that this stuff expands. A lot. So if you’re not careful, you could end up with a big mess on your hands (literally).

It’s Smelly

When you’re spraying foam insulation, there’s a strong odor that comes with it. Some people find it tolerable, but if you have sensitive lungs or are pregnant, you might want to opt for a different type of insulation. 

It’s Not Easy to Remove

Once spray foam insulation dries, it can be very difficult to remove. This is especially true if it’s been in place for awhile and has had a chance to really harden. Because it usually covers all your electrical work, renovations down the road will become much more labor intensive.

Benefits of Spray Foam Insulation Conclusion

While there are some downsides to spray foam insulation, there are also upsides. It’s an effective way to insulate your home and can save you money on your energy bills in the long run. Just be sure to weigh the pros and cons before you decide whether or not this home improvement project is right for you.

And remember, when it comes to insulating your home, spray foam insulation is one of the best choices you can make. It’s eco-friendly, doesn’t off-gas harmful chemicals, stops drafts, improves energy efficiency, reduces noise, prevents mold, fills gaps, and lasts for 50 years or more. With all these benefits, why not give spray foam a try?

  1. Hello! This content is super helpful! I am in the designing phase of the house I plan on building, and spray foam insulation has peaked my interest. You mentioned that there is a smell when installing the spray foam, but is this just when you initially install it? Or does it hold a smell well after its been sitting? Thanks!

    1. Hi Katie! Apologies for the delay here. The smell will eventually go away 🙂 I can’t say for sure how long it took since building/renovating a home brings on all kinds of new home smells, lol, but I’d say maybe a few days? Thanks for your comment and best of luck with your project. XO, Krista
