Energy Saving
Noise Reducing
Sound Deadening Benefits

RetroFoam’s acoustical properties reduce sound by an average of 45 decibels (dB) in a typical 2×4 wall. To put this in layman’s terms, this is like pushing the outside noise 50 yards away(that’s half of a football field!). Did you know that the sound deduction requirement for hearing protection used in an indoor gun range is between 28-31dB? Once RetroFoam is installed in your walls, its unique cell structure absorbs and refracts sound waves making it one of the very best products available for both interior and exterior sound reduction. In fact, it works so well, RetroFoam has been used in many hotels around the US to create quiet rooms without the mess and expense of tearing down walls!

What Our Customers Are Saying

“Since we had RetroFoam installed we noticed the house is much more comfortable. We used to notice the windy days, but now our home is very quiet. We have a bump-out area in the dining room where the floors were always cold, but now we can walk by our bay window in bare feet and the floor is toasty warm.”

Matt R.

“I love RetroFoam! We’re saving 40% a month on our heating bill! Our home is a renovated farmhouse built in the 1940’s. You could honestly hear the winds hiss through the walls. Now our house is comfortable to sit in year round and there are no more drafts.”
