TermoFlex Thermo Acoustic Foam 10 mm

10 mm Cellular Rubber Insulation for Campervans – Ultimate Condensation & Thermal Protection

Stop condensation before it causes rust, mold, and hidden moisture damage.
Our 10 mm Termoflex Cellular Rubber Insulation is a high-performance solution designed specifically for campervan insulation, van conversions, and motorhome builds. With its thicker 10mm structure, it provides even greater thermal resistance and superior condensation control compared to thinner alternatives.

Why 10mm Insulation Is Better for Condensation Control

Condensation forms when warm interior air meets cold metal surfaces inside your van. Without proper insulation, water droplets collect behind panels, leading to corrosion, bad odors, and long-term structural damage.

The 10mm closed-cell rubber layer creates a powerful thermal barrier between the van’s steel body and interior air, significantly reducing temperature differences and minimizing condensation risk.

• Reduces cold bridging on metal panels
• Prevents moisture buildup behind walls and ceilings
• Protects against hidden rust formation
• Improves year-round interior comfort

Advanced Closed-Cell Technology

Termoflex 10mm insulation is made from high-quality closed-cell elastomeric rubber foam, meaning:

• It does not absorb water
• Moisture cannot penetrate the material
• It acts as a built-in vapor barrier
• It maintains insulation performance over time

Unlike fiber-based insulation, it will not trap dampness or lose effectiveness in humid campervan environments.

Enhanced Thermal & Sound Insulation

The increased 10 mm thickness delivers:

• Higher thermal resistance – improved heat retention in winter
• Better heat blocking during hot summer days
• Improved sound dampening against road and exterior noise
• Greater energy efficiency and reduced heating costs

This makes it ideal for full-time van life and four-season camper builds.

Strong Adhesion – No Sagging or Detachment

Many pre-glued insulation products can loosen over time, creating air gaps that allow condensation to return. When installed using a professional high-temperature spray adhesive, Termoflex ensures:

• Long-lasting bond to metal surfaces
• No hanging insulation
• Continuous condensation protection

Installation Recommendations for Maximum Performance

Surface Preparation

Ensure all metal surfaces are clean, dry, and grease-free before application. Proper preparation guarantees optimal adhesion and long-term durability.

Full Coverage Application

Cover all exposed metal areas including walls, ceiling, wheel arches, and doors to eliminate thermal bridges and cold spots.

Precise Cutting

Use a sharp utility knife for clean cuts. The flexible material easily adapts to curved van panels.

Ventilation Matters

Even with high-performance condensation insulation, adequate campervan ventilation is essential to manage interior humidity levels.
