Termoflex XF 19 mm Self-Adhesive Closed Cell Foam Insulation for Campervans & Motorhomes

Termoflex XF 19 mm is a premium self-adhesive closed cell foam insulation designed for campervans, motorhomes, van conversions, boats and commercial vehicles. Manufactured from high-quality elastomeric rubber foam, it delivers exceptional thermal insulation, condensation control and acoustic insulation while remaining lightweight, flexible and easy to install.

With its 19 mm insulation thickness, Termoflex XF is the ideal choice for builders looking to maximise thermal performance. It is particularly suited for campervan walls, ceilings and large body panels where superior insulation helps maintain comfortable interior temperatures in every season.

The material features a high-performance self-adhesive backing that bonds securely to properly prepared metal surfaces, ensuring fast installation and reliable long-term adhesion under vibration, humidity and extreme temperature changes.

Maximum Thermal Insulation for Four-Season Campervans

Vehicle body panels conduct heat extremely efficiently. In winter, valuable interior heat escapes through the metal shell, while in summer the sun rapidly heats exposed body panels, causing uncomfortable interior temperatures.

Termoflex XF 19 mm creates a thick thermal barrier that dramatically reduces heat transfer between the vehicle body and the living space. The increased insulation thickness provides significantly greater thermal resistance than thinner foam insulation, making it an excellent choice for all-season campervan conversions.

If you’re building a campervan for year-round adventures, 19 mm closed cell foam insulation is one of the best choices for large insulated areas.

Why Choose Closed Cell Foam Insulation?

Closed cell elastomeric foam is one of the most widely used insulation materials in the automotive and HVAC industries because it combines excellent thermal performance with outstanding moisture resistance.

Unlike traditional fibreglass or mineral wool insulation, closed cell foam:

• Absorbs virtually no water.
• Helps prevent condensation.
• Does not support mould growth.
• Contains no loose fibres.
• Remains lightweight.
• Is easy to cut and install.
• Maintains long-term performance.

Key Benefits of Termoflex XF 19 mm

• 19 mm insulation thickness for maximum thermal performance.
• Powerful self-adhesive backing for fast installation.
• Closed cell elastomeric foam resists moisture and condensation.
• Excellent thermal insulation for all climates.
• Low thermal conductivity minimises heat transfer.
• High vapour resistance protects vehicle structures.
• Improves interior comfort throughout the year.
• Flexible material easily follows curved body panels.
• Lightweight construction adds only around 1.1 kg/m².
• Helps reduce road noise and airborne sound.
• Dust-free and fibre-free installation.
• Long-lasting professional performance.

Perfect for Campervan Walls & Roof Insulation

Large body panels account for the majority of heat loss inside a campervan. Insulating these surfaces with 19 mm closed cell foam significantly improves interior comfort while reducing heating and cooling requirements.

Termoflex XF 19 mm is especially recommended for:

• Campervan walls
• Campervan ceilings
• Large side panels
• Motorhome body insulation
• Boat cabins
• Commercial vehicle conversions

The additional insulation thickness provides excellent thermal performance without excessive weight, making it ideal for professional camper conversions.

Outstanding Condensation Protection

Condensation is one of the biggest challenges inside campervans. Warm interior air naturally condenses when it meets cold steel body panels, potentially leading to corrosion, mould and unpleasant odours.

Because Termoflex XF is installed directly onto the vehicle body, it keeps the metal surface warmer and greatly reduces condensation formation.

The closed-cell structure absorbs less than 0.1% water, ensuring long-lasting insulation performance even in humid environments.

Thermal Conductivity

Termoflex XF combines excellent thermal conductivity values with increased insulation thickness for outstanding thermal efficiency.

• 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

The combination of low thermal conductivity and 19 mm thickness makes this one of the most effective insulation materials available for campervan conversions.

19 mm vs 13 mm vs 6 mm Insulation

Selecting the correct insulation thickness depends on available installation space and the desired thermal performance.

6 mm insulation is ideal for doors, wheel arches and confined spaces.

13 mm insulation provides an excellent balance between insulation performance and interior space.

19 mm insulation delivers the highest thermal performance and is recommended for campervan walls, ceilings and large body panels whenever maximum insulation efficiency is required.

Professional van builders often combine all three thicknesses throughout the vehicle to optimise insulation while preserving usable living space.

Simple Installation

1. Clean and degrease the metal surface thoroughly.
2. Measure and cut the insulation using a sharp utility knife.
3. Peel away the release liner gradually.
4. Press the insulation firmly across the complete surface.
5. Install adjacent pieces tightly together to reduce thermal bridges.

For best adhesion, installation is recommended at temperatures above +5°C.

Improved Acoustic Comfort

Although primarily designed for thermal insulation, the flexible elastomeric foam also helps reduce airborne noise and vibration.

For maximum vehicle soundproofing, combine Termoflex XF with butyl sound deadening sheets. The butyl layer controls panel resonance while the foam insulation provides thermal insulation, condensation control and additional acoustic absorption.

Frequently Asked Questions

Is 19 mm insulation suitable for campervans?

Yes. It is one of the best choices for campervan walls and ceilings where maximum thermal insulation is required for year-round use.

Can it be installed directly onto metal panels?

Yes. The strong self-adhesive backing is designed to bond directly to clean, dry and grease-free metal surfaces.

Does it absorb water?

No. The closed-cell structure absorbs less than 0.1% water, making it ideal for condensation control.

Does it improve sound insulation?

Yes. It helps reduce airborne noise and improves overall acoustic comfort. The best results are achieved when combined with butyl sound deadening material.

Is 19 mm better than 13 mm?

For large wall and ceiling panels, 19 mm provides superior thermal insulation. Where installation space is limited, 13 mm or 6 mm may be more appropriate.

Can different insulation thicknesses be combined?

Absolutely. Many professional campervan builders install 19 mm insulation on walls and ceilings, 13 mm on medium-depth cavities and 6 mm in tighter structural areas.
