Termoflex XF 6 mm Self-Adhesive Closed Cell Foam Insulation for Campervans & Vans

Termoflex XF 6 mm is a premium self-adhesive closed cell foam insulation designed for campervans, vans, motorhomes, boats and commercial vehicles. Manufactured from high-quality elastomeric rubber foam, it provides outstanding thermal insulation, condensation protection and sound insulation while remaining lightweight and easy to install.

Its flexible closed-cell structure creates an effective thermal barrier between the vehicle’s metal body and the interior, helping maintain comfortable temperatures throughout the year. Whether you’re building a full camper conversion or improving an existing van, Termoflex XF offers professional-grade performance with fast and simple installation.

The material features a high-strength self-adhesive backing that bonds securely to properly cleaned metal surfaces, reducing installation time while ensuring long-lasting adhesion even under vibration and changing temperatures.

Why Choose Closed Cell Foam Insulation?

Vehicle body panels are made from steel or aluminium, both of which conduct heat extremely well. During winter, valuable heat escapes through the bodywork. During summer, sunlight rapidly heats the metal, transferring unwanted heat into the interior.

Closed cell elastomeric foam insulation dramatically reduces this heat transfer. It also helps prevent condensation, one of the biggest challenges in campervan and van conversions.

Unlike fibreglass or mineral wool insulation, closed cell foam absorbs virtually no moisture. It remains clean, lightweight and highly resistant to mould and mildew, making it ideal for automotive applications.

Key Benefits of Termoflex XF 6 mm

• Strong self-adhesive backing for quick and reliable installation.
• Closed cell structure prevents moisture absorption.
• Excellent condensation control for metal vehicle panels.
• Improves thermal insulation during both winter and summer.
• Low thermal conductivity increases insulation performance.
• Reduces heat transfer through metal body panels.
• Helps reduce road noise and high-frequency sound.
• Lightweight material adds minimal vehicle weight.
• Highly flexible for curved and irregular surfaces.
• Easy to cut and install using a utility knife.
• Dust-free and fibre-free for a clean installation.
• Long service life with excellent durability.

Perfect for Campervan Insulation

Termoflex XF 6 mm is widely used in campervan conversions because it provides excellent thermal insulation without taking up excessive interior space.

Its relatively thin profile makes it ideal for areas where installation space is limited, including:

• Van side panels
• Vehicle doors
• Roof ribs
• Wheel arches
• Cab areas
• Sliding doors
• Rear doors
• Floor sections beneath plywood flooring

Many professional van builders combine different insulation thicknesses throughout the vehicle. The 6 mm version is commonly used in tighter areas while thicker insulation is installed on larger wall and roof panels.

Excellent Condensation Protection

Condensation is one of the most common causes of corrosion and moisture damage inside campervans.

Warm, humid air naturally condenses when it meets cold metal surfaces. By installing closed cell foam directly onto the vehicle body, the metal remains significantly warmer, greatly reducing condensation formation.

Because the foam itself absorbs almost no water, it continues performing even in humid environments.

Thermal Performance

The low thermal conductivity of Termoflex XF helps maintain stable interior temperatures while reducing heating and cooling losses.

• 0.034 W/mK at -30°C
• 0.036 W/mK at 0°C
• 0.039 W/mK at +40°C
• 0.044 W/mK at +70°C

These values make Termoflex XF an excellent solution for year-round campervan insulation.

Applications

Termoflex XF 6 mm is suitable for:

• Campervan insulation
• Van conversion projects
• Motorhome insulation
• Boat insulation
• Commercial vehicles
• Car sound insulation
• HVAC insulation
• Pipe insulation
• Technical equipment insulation

Easy Installation

Installation is straightforward.

1. Clean and degrease the metal surface thoroughly.
2. Measure and cut the insulation using a sharp utility knife.
3. Peel the release liner gradually.
4. Apply firm pressure across the entire surface.
5. Install adjacent pieces tightly together to minimise thermal bridges.

For maximum adhesion, installation should be carried out at temperatures above +5°C.

Improves Vehicle Comfort

Besides thermal insulation, the flexible rubber foam also helps reduce airborne noise and vibration. When combined with a butyl sound deadening mat, it creates an effective multi-layer insulation system that significantly improves driving comfort.

Frequently Asked Questions

Is 6 mm insulation enough for a campervan?

Yes. It is an excellent choice for doors, ribs, wheel arches and other confined areas. Many builders combine it with thicker insulation on larger wall and roof panels.

Is it waterproof?

The closed cell structure absorbs virtually no moisture, making it ideal for condensation control.

Can it be installed directly onto metal?

Yes. Simply ensure the surface is clean, dry and free from grease before installation.

Does it reduce noise?

Yes. It helps absorb higher frequency noise while also improving thermal insulation. Maximum soundproofing is achieved when used together with butyl sound deadening sheets.
