Spray foam insulation has become pretty popular in Colorado over the past few years - and for good reason. It seals up your home like nothing else can, which matters a lot when you're dealing with our temperature swings and rising energy bills.
But here's the thing: it's not perfect for every situation.
You'll find plenty of articles that either love spray foam or hate it. We're going to give you the real story - the benefits that actually matter, the drawbacks you should know about, and how to figure out if it makes sense for your home. We've installed spray foam in hundreds of Denver-area homes, and we've seen what works (and what doesn't).
Thinking About Spray Foam? Here's What You Actually Need to Know
By the end of this, you'll have a solid understanding of when spray foam is worth the investment and when you might want to consider other options.
What Spray Foam Insulation Actually Does
Let's start with the basics. Spray foam isn't like the pink fiberglass batts you might picture when you think of insulation.
The Real Benefits You'll Actually Notice
It's a two-component liquid that gets sprayed into place - walls, attics, crawl spaces, wherever you need it. Once it hits the surface, it expands to fill every crack and cavity. That expansion is what makes it special. It doesn't just insulate; it seals air leaks at the same time.
The Drawbacks You Should Actually Care About
Traditional insulation sits in place and slows down heat transfer. That's it. Spray foam does that too, but it also acts as an air barrier. And air leaks are usually the bigger problem in most homes (way bigger than most people realize).
Breaking Down the Cost vs Value
Think of it this way: you can have a thick winter coat, but if it's got holes in it, you're still going to be cold. Spray foam is like having a coat with no holes.
The performance stays consistent over time too. The R-value - which measures how well something insulates - doesn't really change. It doesn't settle or compress like other materials can. Once it's in, it's in.
This is the big one. According to the Department of Energy, air leaks can account for 25-40% of heating and cooling costs. Spray foam stops those leaks cold.
We had a client in Highlands Ranch who was spending close to $400 a month on heating during winter. After we spray-foamed their attic and rim joists, that dropped to around $240. That's real money back in your pocket every single month.
And the comfort improvement? They mentioned they could finally use their upstairs bedrooms in summer without cranking the AC.
