Mass loaded vinyl is a limp, dense membrane that goes inside a wall, floor or ceiling assembly. It works by weight: sound has to move the barrier to get past it, and a heavy, flexible sheet is hard to move. One layer does roughly what three or four layers of drywall would, at a fraction of the cost and the thickness.
It is not absorption. MLV stops sound getting from one room to the next; it does nothing for echo inside a room. If the problem is a room that rings rather than a neighbour you can hear, you want acoustic wall panels instead. Plenty of rooms need both.
Which One Do You Need?
| Product | Weight | Thickness | Wall improvement | Best for |
|---|---|---|---|---|
| Wall Blokker Lite | 0.6 lb/sf | 1/16 in | +6 to 11 STC | Metal stud walls, and anywhere the lightest option matters |
| MLV Sound Barrier | 1 lb/sf | — | +10 STC or more | Wrapping pipe and duct, enclosing a noise source, moulding around a shape |
| Wall Blokker | 1 lb/sf | 1/8 in | +6 to 12 STC | Wood or metal stud walls – the default choice |
| Wall Blokker PRO | 1 lb/sf + polyester scrim | 3/16 in | Widest frequency range | Wood studs, or sandwiched between an existing wall and a new layer of drywall |
All four install the same way – stapled or screwed to the studs, cut around outlets and switches with a utility knife. Not sure which fits your build? Send us the wall construction and what you are trying to keep out, and we will tell you.
