## Overview

Soundsulate LAG Mass Loaded Vinyl with Fiberglass Decoupler is a premium 1" thick composite soundproofing panel combining a 1lb/sf foil-faced mass loaded vinyl barrier with quilted fiberglass insulation. Offering an STC rating up to 29 and Class 1/A fire safety, it delivers superior noise reduction, thermal insulation, and vapor barrier protection—ideal for professional-grade sound control in ceilings, HVAC, and pipe applications.

## Description

Soundsulate Fiberglass Backed Mass Loaded Vinyl is a multi-purpose composite material featuring a flexible barrier laminated to an insulating and acoustical quilted fiberglass and finished with protective layer of Foil Scrim Kraft. This combination forms a thin acoustical product that provides superior sound transmission loss. Sound waves originating from the source will be initially absorbed by the fiberglass and then blocked by the mass loaded vinyl. Any reflected sound wave components will be dissipated into the fiberglass absorber. The addition of the foil scrim kraft outer layer provides a vapor-barrier and fire rated product.

Review: Happy Mom - I used this on top of my existing basement drop ceiling tiles (which I didn’t want to replace) to dampen my love for music going upstairs to my 80-year-old mom. It was a perfect purchase. My mother (and me) couldn’t be happier.

- Significantly higher performance than 1 LB MLV
