10mm Campervan Insulation Kit - Self Adhesive Closed Cell Foam Soundproofing & Thermal Liner (2 x 5m² Rolls)

Upgrade your campervan, van, car, or motorhome with this premium 10mm self adhesive closed cell foam insulation kit, designed to provide outstanding soundproofing, thermal insulation, and condensation control. Supplied as 2 rolls of 5m², this high-performance campervan insulation kit helps create a quieter, warmer, and more comfortable vehicle interior in all driving conditions.

Ideal for campervan conversions, van insulation projects, vehicle soundproofing, and automotive thermal lining, this flexible closed cell foam effectively reduces road noise, engine vibration, tyre noise, rattles, and wind noise while improving overall acoustic comfort and thermal efficiency. The self-adhesive backing allows for fast and simple installation without the need for additional glue or specialist tools.

Manufactured from durable black closed cell foam, this automotive insulation material is water resistant, non-absorbent, and highly compressible, allowing it to easily conform to curved surfaces, roofs, side panels, wheel arches, doors, floors, and vehicle cavities. It also helps minimise condensation build-up while improving heat retention during colder weather and reducing heat transfer during warmer months.

Widely used in campervan conversions, commercial vehicles, cars, motorhomes, marine applications, and automotive sound deadening projects, this premium insulation solution is trusted for its durability, flexibility, and long-lasting performance.

Important Foam Thickness Information

Due to the natural manufacturing process of closed cell foam insulation, slight thickness variations are completely normal. The material is produced using a heat-expansion process that creates millions of sealed air cells inside the foam.

During rolling, storage, and transport, some areas may naturally compress more than others. Because of this, sections of the foam may measure between approximately 8mm and 10mm across different areas of the roll.

This does not affect the insulation’s overall soundproofing, thermal performance, flexibility, or installation quality.

Easy Installation Guide

How To Install

1. Ensure all surfaces are clean, dry, and free from dust or grease.
2. Measure and cut the insulation foam to the required size.
3. Peel off the self-adhesive backing.
4. Apply firmly onto the surface using a roller for maximum adhesion.
5. Press edges securely into place for a neat professional finish.

No additional glue or specialist tools required.

Frequently Asked Questions

Is closed cell foam good for campervan insulation?

Yes, closed cell foam insulation is highly effective for campervan conversions because it provides excellent thermal insulation, soundproofing, and condensation resistance.

Does this insulation help reduce condensation?

Yes, the non-absorbent closed cell foam structure helps minimise moisture build-up and condensation inside vehicles.

Can this insulation be used on doors, roofs, and wheel arches?

Yes, the flexible foam easily conforms to curved vehicle panels, roofs, wheel arches, floors, doors, and side panels.

Is the insulation waterproof?

The foam is water resistant and non-absorbent, making it suitable for automotive and marine insulation applications.
