Description
Stop heat loss, road noise and condensation dead in its tracks. The 6mm Thermo Liner is the UK's best-selling closed cell foam insulation roll for van conversions, campervans, motorhomes and vehicle builds — now in enhanced Version 3 with stronger self-adhesive backing and superior nitrile elastomeric foam.
Why Choose This Thermo Liner?
Unlike standard CCF foam, this premium nitrile elastomeric roll delivers both thermal and acoustic insulation in a single slim 6mm layer. It cuts to any shape, sticks directly to bare metal, and covers 3m² per roll — enough for a full van floor, a set of side panels, or a campervan roof lining section.
Key Benefits
- Thermal Insulation: Ultra-low thermal conductivity of 0.033 W/mK keeps your van warm in winter and cool in summer
- Sound Deadening: Dense closed cell structure significantly reduces road noise, vibration and rattles for a noticeably quieter ride
- Condensation Barrier: High water vapour diffusion resistance prevents moisture build-up and damp on cold metal surfaces
- Self-Adhesive & Easy to Fit: Simply peel, stick and press — roughened adhesive surface grips bare metal, timber and composite panels
- Slim 6mm Profile: Maximises interior headroom and floor space — ideal for tight van build spaces
- Crush Resistant: Retains full insulation performance underfoot on floors and behind panels under compression
- Moisture Resistant: Dense closed cell foam will not absorb water or harbour mould
- Reflective Foil Facing: Reinforced reflective layer bounces radiant heat back into your living space
- Fire Safe: Flammability tested for vehicle interiors to ISO 3795:1989 — safe for campervan and motorhome use
- UK Specification: Designed and tested for the UK climate and vehicle market
Where to Use It
- Van conversion floors, walls and ceiling panels
- Campervan and motorhome thermal lining
- Car boot, footwell and door card insulation
- Wheel arch and underbody lining

How to Install
Installation takes minutes with no specialist tools. Clean the surface, peel the backing, press firmly and roll out air bubbles. Cut to shape with scissors or a craft knife. For best results on curved van panels, score the foam lightly on the reverse before bending into position. Butts cleanly to aluminium finishing tape for a professional finish.
Frequently Asked Questions
How many rolls do I need for a full van conversion?
A standard long-wheelbase van (e.g. Transit LWB) typically requires 8–12 rolls for full wall, floor and ceiling coverage. Use our coverage calculator or contact our UK team for a free estimate.
Can I use this on a van floor under ply?
Yes — this is one of the most popular applications. The crush-resistant foam retains its thermal properties under 12mm or 18mm ply boarding and provides excellent underfloor insulation and noise reduction.
Does it work as a standalone insulation?
The Thermo Liner provides effective thermal and acoustic performance in a single layer. For maximum sound deadening on van metal panels, pair it with a CLD deadening mat applied first to the bare metal.
Is it suitable for a campervan roof?
Absolutely. The lightweight, moisture-resistant foam is ideal for overhead applications. The strong self-adhesive holds securely on overhead surfaces without additional fixings.
