Cork Spray Campervan Insulation — A Dry, Quiet, Year-Round Camper
Spray-applied cork for camper van conversions in Ireland — follows every curve and rib with no gaps, stops the condensation that causes damp and mould, and deadens road noise for a genuinely comfortable touring interior.
The best insulation for a campervan in Ireland
Campervan living puts extreme demands on an insulation system. A tiny metal box parked in the Irish winter needs to hold heat from a modest heater, while the same van in summer sun must stay bearable. And every night you sleep in it, you exhale litres of moisture into the space — moisture that has to go somewhere.
Traditional board-and-wool conversions fight all of this with gaps, voids and vapour barriers that trap damp against the cold steel. Cork spray takes a different approach: it coats every surface in a breathable, thermally-resistant layer that follows ribs, wheel arches and curved roofs with no cold bridges and nowhere for mould to hide.
The result is a drier, quieter, warmer camper — and a steel shell that stays rust-free for the life of the van.
Solving the four problems every camper conversion faces
Year-Round Comfort
Stays warm on winter touring trips and cool when parked in summer sun — a livable interior in every season.
No More Damp & Mould
Breathable cork stops the condensation that causes streaming windows, musty smells and mould in living spaces.
Quiet Cabins
Cork absorbs road rumble, rattles and engine noise, so sleeping and relaxing are genuinely peaceful.
Breathable & Safe
Vapour-permeable cork lets moisture breathe out, so the steel shell stays dry and rust-free for the life of the van.
Why not just use foam boards and wool?
Most Irish campervan conversions are built with rigid foam boards glued to the metal shell, with mineral wool stuffed into the gaps. But every rib, every curve and every wheel arch is a gap — and a gap is exactly where cold bridges, condensation and mould begin.
Cork spray is spray-applied, so it follows every contour with zero voids. And unlike foam boards and vapour barriers, cork is breathable: the moisture you breathe out at night can pass through it and escape, instead of being trapped against cold steel where it causes rust and rot.
Cork also deadens sound, so you get thermal insulation, vapour control and acoustic damping in a single product — no separate mass-loaded vinyl required.
