3mm Closed Cell Foam Car Insulation - Soundproofing & Thermal Barrier
Upgrade your car, van, campervan, or vehicle conversion with premium 3mm closed cell foam insulation - a lightweight thermal and acoustic insulation designed to reduce road noise, vibration, heat transfer, and condensation.
Manufactured from durable self-adhesive closed-cell foam, this flexible insulation helps improve driving comfort by reducing engine noise, tyre noise, wind noise, and panel vibration. The water-resistant and non-absorbent structure also improves thermal efficiency, helping keep interiors cooler in summer and warmer in winter.
Ideal for automotive soundproofing and thermal insulation projects, this foam easily conforms to roofs, doors, wheel arches, floors, boot areas, and side panels for quick and professional installation.
For enhanced soundproofing performance, combine with PeaceMAT XR sound deadening mats.
