Campervan Insulation Specialists

Let's be blunt: you can insulate a van yourself. But a professional job is about more than just cutting foam boards to size. The real difference lies in managing moisture and eliminating thermal bridges—those sneaky cold spots where condensation forms. A specialist creates a complete, unbroken vapour barrier, which is critical for preventing moisture from getting trapped in your van's walls and causing rust or mould down the line. In practice, this attention to detail saves you from costly repairs later. For most Transit-based builds, a professional installation takes one to three days and typically costs between £800 and £2,500, a range that reflects the choice of materials and the complexity of the vehicle's interior structure.

When vetting an installer, ask targeted questions. Start with their approach to vapour barriers and how they handle ventilation. A vague answer is a major red flag. Enquire about the specific materials they recommend for your van model and intended use, whether that's PIR board, sheep's wool, or a hybrid approach. A true expert will justify their choices, explaining the R-value (a measure of thermal resistance) and acoustic properties of each material. Always ask to see photos of their previous work, paying close attention to how they insulate tricky areas like wheel arches, cab bulkheads, and window surrounds. Messy, gappy work in photos often translates to a cold, damp van on the road.
