3mm Closed Cell Foam Van Insulation Thermal Liner - 5m² Roll
This premium 3mm closed cell foam insulation liner is designed to provide excellent soundproofing, thermal insulation, and moisture protection for vans, campervans, cars, boats, and commercial vehicles. Manufactured from high-quality self-adhesive closed-cell foam, this lightweight insulation material helps reduce road noise, engine vibrations, and heat transfer for a quieter and more comfortable interior environment.
The flexible foam structure easily conforms to curved and uneven surfaces, making it ideal for vehicle interiors, exteriors, doors, floors, roofs, wheel arches, side panels, and underbody applications. Its water-resistant and non-absorbent properties help protect against moisture, condensation, and damp while improving overall thermal efficiency.
The strong self-adhesive backing allows for quick and hassle-free installation — simply cut, peel, and apply directly onto clean surfaces without the need for additional glue or specialist tools.
Used by professional vehicle manufacturers and conversion specialists, this versatile thermal liner is ideal for campervan conversions, van insulation projects, automotive soundproofing, and marine insulation applications.
For maximum sound deadening performance, we recommend combining this insulation with PeaceMAT XR sound deadener.
