3mm Closed Cell Foam Car Insulation Sheets - Self Adhesive Soundproofing & Thermal Liner
Upgrade your car, van, campervan, or vehicle conversion with these premium 3mm closed cell foam insulation sheets, designed for effective soundproofing, thermal insulation, and moisture sealing. Manufactured from high-quality self-adhesive closed-cell foam, these lightweight insulation sheets help reduce road noise, vibration, engine noise, and heat transfer for a quieter and more comfortable driving experience.
Ideal for automotive insulation applications, the flexible foam easily conforms to doors, floors, roofs, wheel arches, side panels, boot areas, and underbody sections. The water-resistant and non-absorbent material also helps reduce condensation while improving interior thermal efficiency.
Perfect for both DIY and professional installations, the self-adhesive backing allows for a simple cut, peel, and stick application without additional glue or specialist tools.
For enhanced acoustic performance, combine with PeaceMAT XR sound deadening mats.
