2 lb Mass Loaded Vinyl Barrier

  • 100% Recycled Vinyl

Mass Loaded Vinyl Barrier (MLVB) is a soundproofing material composed of mainly vinyl with a combination of Barium; Calcium Carbonate and EPDM additives to bring up its density and weight per square foot. All supplements are completely safe for human use in soundproofing applications. The difference between the standard 1lb per square foot MLVB and the 2lb per square foot MLVB is simply the thickness and additional weight per square foot of the product.

The Sound Transmission Class (STC) rating increases as the weight of the material increases. Standard thickness varies between 1/16" to 1/4" ranging in density between 1/2lb and 2lb per square foot. Typical applications involve pre-construction walls and ceilings. Use of the material in proper applications and proper installation can greatly increase wall STC ratings. Stand alone Mass Loaded vinyl barrier has an STC rating of up to 32.

Note: Standard Mass Loaded Vinyl Barrier is not recommended as flooring underlayment.
Note: Thicknesses are nominal - weight per square foot is more important.
