MLV 1 inch and MLV 2 inch are another two popular thicknesses.

Mass loaded vinyl MLV does not shrink, rot or cause metal corrosion and also resists unfavorable environmental conditions and UV rays.

It is simple to install MLV mass loaded vinyl soundproofing roll in any application. No matter where the material is installed, it must be installed firmly with no gaps. Any gaps in the barrier should be filled with caulk material and taped over with duct tape or foil tape.

Pipes, pipes and the like

MLV vinyl should be tightly wrapped on the surface, slightly overlapped on joints, and taped the seam with duct tape or foil tape. If taping the seams to hold the thin MLV roll is hard to do, you can not use an aerosols adhesive.

MLV roll for floor

Place the insulation material flat, tie the joints together and tape with duct tape or foil tape. Caulk the perimeter to create a solid installation.

Walls, ceilings or other hard surfaces

To fix the MLV sound insulation material in internal and external applications, use standard dry wall screws or nails with a thin washer or roofer’s nail (with pre-attached plastic or metal gasket). A nail gun with a wide crown is also fast and efficient way to tighten the MLV. All joints should be butted together. Caulk all perimeters including around outlets.
