Car Builders Mass Loaded Vinyl (MLV) is a heavy weight sound blocking material. Mass Loaded Vinyl features a grained presentable face and is backed with a woven textile backing. This backing allow the use of contact adhesive to glue the material down, typically MLV is difficult to glue and is limited to using toxic vinyl cements. As a limp sound blocking barrier, MLV is designed to block sound waves and work as a sound blanket. When applying MLV it is important to use a de-coupling layer to seperate contact from the vibrating substate, our Insul-layer foams work for this application.

Very effective noise blocker... Although I didn't used this product in an automotive application, I can vouch it works brilliantly in blocking those pesky unwanted noises in a building application too!! I used it on an instant hot water unit cabinet, mounted in a external brick wall, adjacent to a bedroom. Works brilliantly. Easy to use & apply with contact glue. Great advice & great service from the team too.
