Insulation - How much?

[Tom2023]

I was wondering what thickness of kingspan to use on the floor, the sides and the roof of my van.

I was also wondering just how effective Kingspan on the floor, sides and roof actually is at keeping a van warm. The windows won't be insulated neither will the driver & passenger area. That's a lot of glass for heat to escape from. Not that I plan visiting the Artic Circle.

We used basic loft insulation 4" from homebase 2 rolls off have used the van in snow and warmth and great in both, fits nicely behing the wall and ceiling board, didn't do floor the van is great.

We're fine weather leisure campervanners. Not hard core canmping in a scottish layby in Jan campers. I did ours with the recycled silver bubble stuff from B&q warehouse, before boarding and carpeting.

Kingspan is good as i use it at work for wall and soffit insulation, but if you go to buy it, boy... is it expensive!
ide stick with lagging if i were you.

I've used both, loft ins is cheap but very messy to work with, if your not going to cover the windows or cabin area I wouldn't bother, but unless you but something over the open spaces it gets very cold!! I but heavy curtains on these areas and loft inst everywhere else and used it all year round! Perfect!!
