5mm/10mm Car Soundproofing Mat Closed Cell Foam Thermal Noise Insulation

Cut road noise, panel vibration, and heat transfer with a flexible car soundproofing mat built for vehicle and utility insulation.

This self-adhesive sound insulation sheet uses a butyl-based rubber visco elastic active layer with an aluminium constraining layer to reduce drumming, rattles, and unwanted vibration. It is soft, easy to shape, and simple to install on curved or flat surfaces.

Choose 5mm or 10mm thickness to suit your project, whether you are insulating a hood, door, trunk, chassis, fender, roof, indoor wall, RV, camper, or speaker cabinet. The waterproof, odourless, non-flammable construction is made for hot and cold temperatures.
