Soundproofing Insulation

Sound travels through air gaps and through hollow walls. Fluffy fiberglass helps a little, but dense insulation, sealed outlets, resilient channel and a tight door make a much bigger difference. The goal is to add mass, damp vibration and close the gaps.

We add sound control to walls, floors and ceilings across Nashville and Middle Tennessee. We use mineral wool, dense-pack and acoustic foam, seal the small gaps that let sound through and coordinate with drywall crews for added layers where a room needs more.

FAQ

Common questions about soundproofing insulation

Does foam on the wall block sound?

Thin acoustic foam only improves echo. Blocking sound takes mass, sealed gaps and layers.

Can you soundproof an existing room?

Often, with dense-pack from the attic and added drywall layers. We explain what is realistic.

What gives the biggest improvement?

Sealing gaps and adding mass in the wall. Doors and ducts often matter as much.
