Mass Loaded Vinyl is a heavy, limp barrier sheet that blocks that sound like a blanket. It weighs 4kg per square metre, is 2mm thick and comes in a 1.35m x 1.95m sheet. The woven textile back lets you glue it with contact adhesive, and it works best over a decoupling layer such as Insul-Layer foam.\u003c\/p\u003e\u003c\/div\u003e\n\u003ch2\u003eWhat problems does the Mass Loaded Vinyl fix?\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMotor noise coming through a 4WD or truck firewall.\u003c\/strong\u003e Car Builders list it as a firewall barrier for 4WDs and trucks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBoot drone from the exhaust on sixes, V8s and flat fours.\u003c\/strong\u003e Laid in the boot as a liner, it cuts that drone.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMLV that will not glue.\u003c\/strong\u003e The woven textile back takes contact adhesive, so no toxic vinyl cement.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNeeding to get back to the panel later.\u003c\/strong\u003e Use it as a removable sound blanket where peel and stick is not wanted.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eHow it works\u003c\/h2\u003e\u003cp\u003eSound needs to move mass to get through a barrier. MLV is heavy and limp, so it soaks up airborne noise instead of passing it on. Separate it from the vibrating panel with a decoupling foam so the panel does not drive the vinyl.\u003c\/p\u003e\n\u003ch2\u003eWhat is in the box\u003c\/h2\u003e\u003cul\u003e\u003cli\u003e1 x Mass Loaded Vinyl sheet, 1.35m x 1.95m, 2mm\u003c\/li\u003e\u003c\/ul\u003e\n\u003ch2\u003eHow much do I need?\u003c\/h2\u003e\u003cp\u003eOne sheet is 1.35m x 1.95m.
