Full Review
3M Thinsulate SM600L is the insulation material most commonly recommended by experienced van builders for wall cavities and ceiling panels. It's a synthetic textile insulation that doesn't absorb moisture (unlike rockwool or fibreglass), provides genuine thermal resistance, and significantly reduces road noise.
How Much to Buy
A standard HiAce or Transit van requires approximately 10-15 linear metres of 1.5m wide Thinsulate to cover all wall and ceiling cavities. Buy extra — it's better to have leftover than to run short mid-build.
