in this country the biggest problem is the change in both temperature and humidity , yep if you put insulation on anything metal and you dont vapour seal it it will run water if your not very careful i do know what im talking about really , vent ducts are metal like a bus get hot cold etc , you must put a vapour barrier or you will get moisure , its why you dont get water dripping from duct supports in ceilings .just saying thats all, as bs n chris says you can over kill it is only a bus that you use occasionally when its cold , so yeh propex but a good duvet is just as good ta keep you warm ta be honest , if you wana get up in the night n prance about naked in the winter ,then worry about it , id say dont you will make tings worse if you arnt careful but what ever.
What you could do Ken is cut a head hole and 2 arm holes in a sleeping bag and wear it like a nice thermal dress, then you won't need insulation.
No worries....I'll write a list of products that actually work in the ice formed on your windows @chrisgooner Sleep tight...
Do nothing and use the Jap blanket technique eh @vanorak The beauty of insulating your bus is it will be much more tolerable to drive in the winter . Those pattern exchangers will do the job then. Interesting thread this. Ask a question - get the perfect answer then get everyone else extolling the vurtues of tin foil and sticky back bubbly closed open cell tapjoint sealed cornflake boxes and telling you your talking carp. The answer is do what you want to do, go as far as your comfortable. Happy to do some thermal imaging at techenders to prove and disprove the efficacy of the various methods.
@Dicky nobody's knocking what vanorak has said just merely pointing out a different option and opinion. I may not be an "expert" in the field of insulation but being a bus owner that uses his bus as a daily come rain, shine or snow and also camps in the winter, foil bubble wrap has worked for me. There really is no point insulating a bus if you garage it in the winter and use it 3 or 4 times in the summer like many do on this forum.
se superquilt holds no water can be stuck in the ribs and between glass and door in the front , it costs 70 quid a roll and you will need 2 , 3 if you do the roof , warmer winter cooler summer sterio sounds better , its worth the time and effort. BazzU
I'm sure there are many ways to skin this cat and it's a discussion forum after all. My Westy didn't have any insulation unless you count a few bits of glass fibre loft insulation stuffed behind the panels. I haven't bothered to install any in my present bus and I find it fine, though I do have OG heat exchangers, my door seals fit and I have Eber for taking the chill off when camping. While I enjoy reading @vanorak 's reasearched (sometimes) views on all things campervan and appreciate the time and trouble he puts in to explain his ideas, if I went with everything he suggested for every area of my bus, without questioning, I'd be even skinter and like his, my van would still be off the road.
My original front panel had a thin polystyrene type backing to it. It looked factory - could it have been. The roof had rockwool in it! I think there was also rockwool in the side panels. It was a Westy Continental but dont know if that was standard or not!
Pretty sure the polystyrene in the front panel is original. I have it in mine. Haven't found any rockwool yet.
I had been considering insulating the inside of the front panel. Just to clarify - the vapour gap needs to be between the outer (metal) panel and the insulation?
