The Aerofoam NBR self-adhesive insulation board is a high-quality, closed-cell elastomer foam that provides excellent thermal and acoustic insulation. With a low heat conduction coefficient of approx. 0.035 W/m·K and a high vapour diffusion resistance (μ ≥ 10,000) effectively prevents condensation and heat loss — perfect for (bus) motorhomes and caravans, off-grid installations and other RV construction projects. The flexible yet robust structure makes assembly easy, while the integrated adhesive layer ensures a fast, neat finish without additional glue. Aerofoam is self-defening, dust- and fibre-free, with antibacterial Ultra-Fresh protection and free of CFKs or formaldehyde. This way you create a comfortable, quiet and healthy indoor climate in every vehicle or adventurous project. Aerofoam NBR offers the same performance as the more well-known Armaflex, but is an alternative with the same professional quality and durability.
