insulation aluminium thermal foil or space wrap glass fibre?
hi there, i was all for going the space wrap route, and kitting out the inside of panels with this, taped to them with aluminium foil. now i am not so sure. if they have to be taken off, the fibreglass will come out and it's itchy and not very good to breathe in.
on the wiki, people seem to be into this Aluminium Thermal Foil M/P Insulation Silver Length 7.5m x Width 600mm
at about 12 quid for this amount, it is pretty economical. would i need this stuff and some space wrap behind it too or would this suffice?
this would be easier to take in and out if i had to do any panel checking, servicing of panels etc, and it seems to be friendier to work with. is it just as good in terms of insulation and sound insulation? the length and width seem to be doube that of space wrap and i figure it would cost me 50 quid to do the whole (panel) van, would this be a correct estimate?

I went for the thermal aluminium wrap, instead or space wrap.
I was wary of the glass wool attracting moisture.

I've used space wrap but the bag isn't sufficient on its own to keep out moisture so used bin bags as a second layer. Not many places you can use space wrap anyway other than rear sides. Have to say, since insulating, interior is quieter too - lots quieter. At RTTH could barely hear the band with door shut.

covs, did you wax oil all your interior panels or just around the seams at the bottom?

Just around bottom. The problem with waxoyl is that if you ever need to weld in that area again it tends to catch fire and/or gives you a whole lot of cleaning and scraping to do.

Re: insulation aluminium thermal foil or space wrap glass fibre?
in the panels I have just stripped out the westy insulation in the side panels and flushed with vactan. Then a good sized drain hole under the fridge outer sill inner (horizontal sill fridge had made its own hole
). I have gone for silver backed bubble wrap in the (high top) roof. Rear door, sliding and front doors silver backed bubble wrap and lead flashing replacement on a roll. It might not be as quiet as other options but I will probably want the option to weld in the future and I reckon if the moisture has an escape route, so long as I can see it and treat it as necessary I can keep on top of it. Cram it full of any type of insulation and you have a moisture trap. If not from internal/external condensation then from window/high top/ drips or internal condensation from windows dripping down. I have a derv heater, I can crank that up if it get cold and the moisture has an out. That's my take time will tell....

Re: insulation aluminium thermal foil or space wrap glass fibre?
Agree Bob. Any rust traps I've ever dealt with have been modified to allow for better ventilation and/or a route for any moisture.
The bubble wrap stuff seems about the best material most places due to its non-porous quality, particularly front doors where space is limited and under front mats, seats etc. To be fair, insulating a tin box is never going to be easy and lots of daft if not ridiculous ideas sprang to mind when I did mind including (at one point) the idea of filling some cavities with expanding foam but that would be asking for a whole heap of trouble - please don't anyone do that.
One place that did lend itself well to space blanket was the tailgate and I fitted a better moisture membrane made from the thick polythene display wrapping the space blanket came in. Makes sleeping that end lovely and quiet although having camped quite a bit this year I now realise I need to fit some low level lighting on that rear door. Found some great ones at RTTH which hopefully I can fit tomorrow.

Re: insulation aluminium thermal foil or space wrap glass fibre?
I've bought a roll of this stuuf to do the insides of my van while its all distmantled. According to the blurb that came with it, its moisture and damp proof so I guess its the way to go. I'm going to stick mine on with some sprya trim adhesive - got plenty left over from the retrim works - and probably double it up where I can if theres any left over.
The spec.sheet reckons this stuff is as effective as a piece of 5 cm polystyrene sheet, so it should be ok.
I'll put some images of it when I've got it fitted.

Re: insulation aluminium thermal foil or space wrap glass fibre?
Just a bit of a ramble, If I was going to winterise it I would probably use a vapour barrier over all internal voids, this could be the bubble wrap stuff if you can get a good seal against the metal, ie taped down over the edges on the internal face of the van interiors with moisture resistant aluminium tape. Sliding door may be an issue as the internal panel wont fit if you have a layer of insulation behind it, you could in theory put the insulation on the external face of the interior metal panels attaching it by putting the tape on the inside face (making sure it cant be seen) with the sticky side facing outwards. That way you keep the warm air+ moisuture on the inside of the van where it should be and not warming the void itself. The entire interior would need to be stripped first, or a new build in a panel. In the voids on the self build motor home forum many people are using the kingspan type cavity board insulation, cut into chunks and stuffed in the voids. If you could do this throughout the lower half of the van you would have about as insulated a vehicle as you can get. Of course that's only half a van and the heat tends to rise, windows tend to be the greatest moisture generators even with silver screens. That water has to go some where... I have seen folks wiping them down with a towel in the morning, probably a good idea short of sticking a dehumidifier in it when your not using it! I like the cold front cab that the Westies have by having curtains accross the rear of the front seats. Rust treatment would preferably be done in advance as it would be a ball ache to get to in future. Some clear dinitrol put down in the cavities after either treating with vactan or even better replacing any rusted metal would be my route give time tools money etc...

Re: insulation aluminium thermal foil or space wrap glass fibre?
I think I am going to put a square of that flashing on the middle of panels to sound insulate. I think I saw a picture in a homebrew build thread. might be you bob?
