Insulation’s usually talked about in terms of saving energy — and fair enough, that’s a big part of what it does. But if you’ve ever been kept awake by traffic, noisy neighbours, or even someone clomping around upstairs, you’ll know there’s another benefit that matters just as much: peace and quiet.
That’s where spray foam insulation comes into its own. Yes, it keeps heat in — but it also does a brilliant job at blocking out unwanted noise. And in busy homes or shared spaces, that can be a game-changer.
How Does Spray Foam Help with Sound?
Here’s the short version: when spray foam is applied, it expands to fill every gap and crack. That means fewer places for noise (and air) to sneak through.
Unlike old-school materials like fibreglass or mineral wool — which mainly absorb sound — spray foam creates a dense, airtight barrier. This makes it much better at stopping noise from travelling through walls, floors, or ceilings in the first place.
More Privacy Inside the House
Shared spaces come with shared sounds. Maybe you’ve got kids playing in the next room, someone working from home, or a TV turned up a bit too loud. With spray foam in your walls or floors, sound doesn’t travel the same way. Everyone gets their own bubble of quiet.
Your Home Just Feels Calmer
Once the noise dies down, you notice it. Everything feels more peaceful — easier to concentrate, easier to relax. Even sleep improves when you’re not being jolted awake by outside noise or footsteps upstairs. It’s the kind of upgrade that changes how your home feels, not just how it runs.
And Yes — It Still Insulates for Heat
This isn’t a one-trick product. Spray foam also acts as thermal insulation, so you’re not just blocking noise — you’re locking in warmth (or cool air, depending on the season). You’ll probably notice fewer draughts and a more stable indoor temperature pretty quickly.
Where Can It Be Used?
Just about anywhere, really. We’ve used spray foam to soundproof:
- Bedrooms
- Home offices
- Media or games rooms
- Between floors in a multi-storey home
- Shared walls in flats or HMOs
- Lofts and basements being turned into living space
- Even commercial units or studios
It works just as well in new builds as it does in older properties — and we’ve installed it in all sorts of places over the years.
Is It Worth the Effort?
If you’re fed up with noise and you’ve tried the usual fixes — rugs, thicker curtains, asking nicely — then yeah, spray foam is definitely worth a look. It’s a long-term solution that doesn’t need topping up or replacing down the line. Once it’s in, it just gets on with the job.
And the bonus? It’s a 2-4-1 solution: cutting noise and slashing heating bills.
