Barrier Decoupler - Vinyl noise barrier with closed cell foam decoupler

In modern construction, achieving reliable noise transmission control without sacrificing durability or sustainability can be a challenge. The Mass Loaded Vinyl Sound Barrier with PVC Foam Decoupler from Acoustical Surfaces was designed to meet that challenge head‑on. This professional‑grade roll combines a high‑density vinyl sound barrier with a closed‑cell PVC foam decoupler, creating a multi‑functional sound isolation barrier that excels in both residential and commercial environments.

At its core, the product features a mass loaded vinyl barrier weighing 1 lb. per square foot, paired with a ¼‑inch foam layer that provides effective vibration decoupling. Together, they form a soundproof construction layer that enhances acoustic separation between surfaces, delivering measurable improvements in wall soundproofing, soundproof drywall backer assemblies, and retrofit soundproofing projects. With an STC rating 27 acoustic barrier, it offers dependable performance for designers and builders seeking proven results.

Versatility is one of its defining strengths. This barrier can be applied behind walls, ceilings, and floors, serving as noise control for walls, ceilings, and floors in offices, schools, and multi‑family housing. It also adapts to specialized uses such as soundproofing HVAC ducts, soundproofing machinery and equipment enclosures, and even soundproofing pipe wrap or drain line soundproofing. In industrial and mechanical settings, it functions as a Barrier Decoupler PVC sound barrier, while in transportation it doubles as an automotive soundproofing and automotive noise control barrier solution.

Beyond acoustics, the material provides a thermal insulation barrier layer, helping stabilize temperatures and improve energy efficiency. Its construction ensures it is a durable moisture‑resistant sound barrier and a mold and mildew resistant acoustic barrier, capable of withstanding demanding environments. Safety is built in as well, with compliance to UL 94‑HFTI Class C fire‑rated barrier standards.

Manufactured with care, this product is an eco‑conscious PVC soundproofing material, designed to support sustainable building practices while delivering long‑lasting performance. Easy to install—whether mechanically fastened to solid surfaces or laid onto horizontal assemblies—it is a practical solution for professionals who need reliable sound control without compromise.

The Mass Loaded Vinyl Sound Barrier with PVC Foam Decoupler is more than just a roll of material; it is a complete noise control solution. From retrofit soundproofing in residential walls to noise reduction panels for industrial spaces, it provides the strength, flexibility, and sustainability needed to meet today’s acoustic challenges.
