removed old head liner and have recently fitted kingspan 20mm insulation in all other parts of van, question is due to being a large curved area best alternative.
You can get that multi layer foil insulation which is very thin but more effective than kingspan, so they say.
Yes that's the stuff good quality works well .bit pricey but removed it from a building site that I was working on so not to bad this is the inside done
