If you’re converting a UK van, “vapour barrier” gets thrown around a lot—but the real question is whether your build actually needs one for how you’ve layered insulation, lining, and ventilation. Done wrong, it can trap moisture and undermine your thermal performance; done right, it helps manage condensation where it belongs. In our latest workshop breakdown, we lay out the practical decision points for campervan walls and ceilings, from substrate choice to build-up sequencing. It’s the kind of guidance that saves time, avoids costly rework, and keeps your van quieter and warmer year-round.
