TermoFlex Thermo Acoustic Foam 5 mm

5mm Cellular Rubber Insulation for Campervans – Maximum Condensation Control with Termoflex

Condensation is one of the biggest threats in a campervan.
Cooking, sleeping, heating, and temperature differences between inside and outside air create moisture that turns into water on cold metal surfaces. Over time, this can lead to:

• Rust and corrosion inside body panels
• Mold growth
• Damp insulation
• Unpleasant odors
• Reduced thermal performance

Termoflex 5mm Cellular Rubber Insulation is specifically designed to combat condensation at its source.

Why Condensation Control Is Critical in Campervans

Campervans are made of metal — and metal cools down quickly. When warm interior air hits cold steel panels, moisture condenses into water droplets. Without proper insulation, this moisture gets trapped behind panels and furniture.

Termoflex acts as a closed-cell vapor barrier and thermal break, reducing the temperature difference between interior air and the van body. This dramatically lowers the risk of condensation forming in the first place.

How Termoflex Prevents Condensation

Closed-Cell Structure (Moisture Resistant)

Termoflex is made from high-quality closed-cell cellular rubber. This means:

• Water cannot penetrate the material
• It does not absorb moisture
• It prevents damp buildup behind panels

Unlike open-fiber insulation materials, Termoflex will not trap water.

Thermal Barrier Against Cold Metal

By adding a 5mm insulating layer between interior air and the steel body, Termoflex reduces cold bridging. Less surface cooling equals less condensation.

Reliable Adhesion (No Sagging Over Time)

Many pre-glued insulation products eventually detach from the metal surface. When insulation separates, air gaps form — and condensation returns.

Termoflex, when installed with a quality spray adhesive, ensures:

• Strong long-term bonding
• No hanging insulation
• Continuous moisture protection

Additional Benefits Beyond Condensation Control

• Excellent thermal insulation – keeps heat inside during winter and reduces heat gain in summer
• Sound insulation properties – reduces road and exterior noise
• Flexible and easy to install – ideal for curved van surfaces
• Dust-free and safe – no harmful particles in indoor air
• Cost-effective alternative to premium brands

Installation Tips for Maximum Condensation Protection

1. Proper Surface Preparation

Clean, dry, grease-free metal is essential for strong adhesion and long-term moisture protection.

2. Full Surface Coverage

Cover all exposed metal areas to eliminate thermal bridges and cold spots.

3. Tight Seams

Install pieces tightly against each other to avoid air gaps where condensation can form.

4. Use High-Quality Spray Adhesive

Professional-grade, high-temperature spray adhesives ensure lasting performance even in hot summer conditions.

5. Maintain Ventilation

Even with excellent condensation insulation, proper camper ventilation is necessary to control interior humidity.

The Smart Choice for Condensation-Free Camper Living

If you’re building or upgrading a campervan, condensation protection should be your top priority. Termoflex 5mm Cellular Rubber Insulation provides a reliable, professional-grade solution that:

• Reduces condensation risk
• Protects against rust and mold
• Improves thermal efficiency
• Enhances overall camper comfort

Invest in insulation that works long-term — not just on installation day.
