Reflective bubble stuff has a appalling U value lots of hype on the van forums but none of the caravan / motorhome manufacturers use it...TopSod wrote:
Point worth mentioning on insulation, don’t use anything that is traditionally made for your loft, it’ll hold moisture and rot your van. Go for the reflective bubble stuff or similar

Or a decent underseal / cavity wax on the body mineral wool battened to prevent compression then a vapour barrier eg polythene and decorative cladding
And don't forget the floor.......

Most people also forget to ensure sufficient ventilation which will reduce condensation build up in the first place. don't forget you cook )butane has a high water content, as well as boiling rice / the kettle) sweat and shower in a 7ft x10ft X 6ft ISH box .... Also ensure sufficient gas drop holes as per the regs and easy to open exits so you can get out quick! And have a decent Carbon monoxide alarm installed as per the instructions... A lpg alarm isn't a bad idea either
A person in a sedimentary position in a comfortable environment temperature wise looses 500-750ml per day from sweat... If you have ever slept in a single skin tent on a cold night you will understand the reason for the name " a bath tub ground sheet ";)
I've come off a few forums on the subject as some Muppets just don't like being told their "wonderful creation" is a death trap waiting to happen from shoddy gas work just because you can use a rubber gas hose to run gas from a internal "box" to a cooker putting the hose through storage lockers etc doesn't mean you should for example to frankly leathal electrical work and more body filler than a mot man can poke at the joys of forums
