Soundproofing…it’s more than likely the first word that comes to mind when you are working around in your home and then you hear the neighbor’s dog barking, the neighborhood kids playing outside, or the teenage driver whose car is in desperate need of a new muffler.   You feel as if you are doomed, but don’t claim defeat!  RetroFoam is the BEST way to reduce those exterior noises!

RetroFoam’s acoustical properties reduces sound by 45-50 dB on average!  Currently, you may be wondering, “Why is a 45-50 dB reduction so significant?”  If you’re familiar with the ear protection that is used in shooting ranges, that gear has an average of 28-31 dB loss.  When comparing the two, RetroFoam has a greater dB reduction than the shooting range protective gear by 38%!

A recurring misunderstanding we often face is that insulation can soundproof your home.  To soundproof a structure means to create friction to the passage of sound, which results in blocking the sound entirely.  While insulation in any form cannot soundproof your walls, it CAN deaden the sound.  Here at RetroFoam of East Tennessee we take great pride in the fact that we can deaden that sound significantly!

Sound deadening reduces the vibration of volume.  In order to fully grasp the benefits of RetroFoam’s sound deadening abilities, we need to understand the basics of how sound travels.

According to GIK Acoustics in Atlanta, Georgia, sound travels in two ways — throughout the air and through structures.   Airborne sound is very simple to understand.  Any open air you have in a room are considered sound leaks–for example, outlets, HVAC ducting, electrical switches, etc.

When sound travels through structures, the sound vibrates those structures as well as everything connected to them–walls, floors, duct work, etc.  Those vibrations duplicate and magnify the sound, resulting in a noisy home.  However, with RetroFoam, we can help you transform your home into a quiet oasis with its ability to sound deaden.


RetroFoam is an injection foam that is 60% closed cell which allows it to absorb an extreme amount of sound energy–reducing your noise level by up to a momentous 75%!

Whether you’re battling outdoor noise, or an annoyingly loud dryer, or a combination of the two, RetroFoam of East Tennessee is here to help!
