3mm Closed Cell Foam Car & Van Insulation Roll - Self Adhesive Thermal & Acoustic Liner 10m x 1m

Upgrade your car, van, campervan, boat, or vehicle conversion with this premium 3mm closed cell foam insulation roll, designed for effective thermal insulation, sound deadening, and moisture protection. Manufactured from high-quality self-adhesive closed-cell polyethylene foam, this professional-grade automotive insulation helps create a quieter, more comfortable, and temperature-controlled interior environment.

Perfect for automotive soundproofing and thermal insulation projects, this lightweight yet durable insulation liner significantly reduces road noise, engine vibration, tyre noise, rattles, and exterior sound while improving overall vehicle acoustics and interior comfort.

The advanced closed-cell foam structure provides excellent thermal insulation and water resistance, helping reduce heat transfer and minimise condensation build-up inside vehicles. Its highly flexible design easily conforms to curved panels, doors, wheel arches, roofs, floors, side panels, and underbody areas for a clean and professional installation.

Featuring a strong self-adhesive backing, this insulation roll offers fast and hassle-free installation — simply cut, peel, and apply without the need for additional glue or specialist tools.

Widely used in professional automotive, campervan, marine, and vehicle conversion applications, this insulation material delivers reliable long-term performance while remaining lightweight, moisture-resistant, and flame-retardant.

For maximum soundproofing performance, we recommend combining this insulation with PeaceMAT XR sound deadening material.
