Vicoustic Iso Blanket

$287.28 ~~$399~~ In stock

Iso Blanket and Iso Blanket Pro are limp-mass solutions designed for the treatment of airborne noise. They differ in their STC (Sound Transmission Coefficient) in that Iso Blanket Pro has a bigger coefficient/performance due to its agglomerated fabrics.

The blankets perform as sound barriers when applied to ceilings, walls, and floors. Their flexibility, thin design, and high resistance make them easy-to-use materials. They are most effective when used in construction projects that involve several layers of different materials. Density of 4,5kg/m2 in the Pro Version and 6.5kg/m2 in the Standard Version, ensures a high level of isolation by diminishing the sound emitted from joins between the floor and the rest of the construction.

Andrew F. ★★★★★ Oct 22, 2026

I was skeptical about limp-mass blankets for soundproofing, but the Iso Blanket's STC rating actually works—my noisy neighbors are now a faint muffle. It's dense enough to feel substantial yet easy to hang with the included grommets.

Adam H. ★★★★★ Oct 21, 2026

Hanging this in front of my home office door cut the neighbor's TV noise way down, and the limp-mass weight feels solid without being a hassle to drape. The STC difference between this and the Pro version made me think about my ceiling, but for a bedroom wall this does the job.

The STC rating on this limp-mass sheet is the real deal—my neighbor's bass thump dropped noticeably the day I hung it. I was worried about installation, but it cut easily and stayed put without sagging.
