insulation

Post by tezzer22 » Wed Dec 14, 2011 6:58 pm

hi all , this cold weather has got me thinking about filling the gap between the interior trim panels and the outer body with loft insulation material , has anybody done this ? could this cause issues with rust by trapping moisture ?

I did using Sheep's wool insulation (B&Q had a deal on at the time).

I sprayed Waxoyl on the insides of the panels first, then stuffed it in.

Difficult to say how effective it is, since I've not got an un-insulated Bongo to compare - but it's always warm at night even without the webasto on!

I know of one person who insulated their van and its now too hot in the summer, so don't go too mad with it. Probably better to put a thin layer in and use a heater to control the ambient temperature.

Interesting. Kind of makes you think that removable inner lining could both insulate and provide blackout, if it were full length.

The 'tin foil' layer may attract condensation, Rockwool slabs are used in cavity walls and impervious to the elements, saying that I after waxoiling I used loft insulation. Also use it as packing in race silencers as heat doesn't affect it. :wink:

Ive been to two proffessional camper van/van converters (not the get rich cowboy's) both used a form of bubble thermo foil insulation, pricey stuff, not a B&Q product.

:? That surprises me, insulation normally has the effect of keeping the heat in during cold weather & the heat out in warm weather as it works both ways. Clearly any heat already in the van will stay there longer with insulation but equally a nice a/c cooled van should stay cool longer as in a fridge which has loads of insulation.

So true,but a fridge does not have windows or a sun roof. :)
