Sound DefendR™ MLV with Foam Properties

Sound DefendR™ Mass Loaded Vinyl with Closed Cell Foam is created from laminating a 1/4" thick, dense, closed cell foam onto our proprietary Noise Grabber™ Mass Loaded Vinyl. Our MLV with Foam retains the density and flexibility of MLV, while using the foam as a decoupling layer for sound and thermal insulation. Sound DefendR™ is easy to install with spray adhesive or a dual sided adhesive (attached to the foam side only) and can be cut to shape easily with a utility knife. Due to its non-toxic design, Sound DefendR™ MLV can be safely installed inside homes, cars, or offices without any of the concerns that apply with some other forms of sound reducing materials.
