Camper Van Insulation

Insulation is one of the most important steps in any camper van build, helping regulate internal temperature by keeping heat in during winter and reducing heat build-up in summer. It also plays a key role in minimising condensation and damp, which can otherwise lead to mould and long-term damage. Effective insulation transforms your van into a more comfortable, year-round living environment.

The Wired Campers collection includes a variety of insulation materials designed for different stages of a build. Common solutions include self-adhesive closed cell foam, thermal foil insulation and soft-fill materials for cavities, all of which work together to create a complete insulation system. Multi-layer insulation approaches are widely used in camper van conversions, combining sound deadening, thermal insulation and vapour control to achieve the best results.

Sound deadening materials are typically applied directly to metal panels to reduce vibration and road noise, creating a quieter interior. Thermal insulation layers are then added to retain heat and improve energy efficiency, while lightweight fill materials are used in hard-to-reach voids to eliminate cold spots. This layered approach is commonly used in professional camper van builds to achieve both acoustic and thermal performance.

Insulating your camper van not only improves comfort but also increases the efficiency of heating and cooling systems, reducing overall energy consumption when using diesel heaters or solar-powered electrical setups. Whether you’re building a simple weekend van or a fully off-grid camper van, proper insulation is essential for creating a practical and enjoyable living space.
