ASLONG Professional Mass-Loaded Vinyl Acoustic Barrier — High-Density Sound Insulation

ASLONG mass loaded vinyl delivers professional-grade, high-density acoustic isolation designed for construction, automotive, residential and entertainment facilities. Engineered for consistent sound reduction and long-term durability, this flexible sound barrier gives installers and specifiers measurable, reliable results while minimizing lifecycle risk.

Engineered for Uncompromising Reliability

Consistent Acoustic Performance

Manufactured under controlled processes, ASLONG high-density acoustic membranes provide repeatable sound attenuation across projects. Quality-controlled production ensures uniform mass and thickness so performance does not vary from batch to batch—reducing rework and guaranteeing predictable results for contractors and designers.

Durable, Long-Life Construction

Our soundproofing membranes are formulated to resist cracking, delamination, and moisture-related degradation common in lower-grade barriers. The result is a low-maintenance, long-service-life product that preserves acoustic function over years of normal use, protecting your investment and minimizing future repair costs.

Professional-Grade Performance and Application Ease

Versatile Installation

ASLONG acoustic barriers are flexible and easy to handle, conforming to irregular surfaces and integrating smoothly with walls, ceilings, floors and vehicle panels. Cut-to-fit adaptability and compatibility with standard adhesives and fixation methods streamline on-site labor and accelerate project timelines.

Measurable Results Across Sectors

Designed for construction, automotive, industrial and entertainment applications, our barrier material reduces airborne and structure-borne noise when combined with standard decoupling or damping systems. Its high surface density supports predictable dB reductions when specified and installed according to best-practice assemblies.
