no insulation

[69billy]

camped out this weekend and woke to a frosty windowed van on the outside ! , I ripped out the lagging in the summer as im sure it caused the condensation..this morning dry and toasty. propex didn't cut in till the door was opened . so people thinking of lagging i don't think its needed its no colder just drier 3 of us in him and no bobble hats

True, I ripped the last of the insulation out of the roof yesterday ready for some work and the metalwork was dripping wet.

insulation is the devil!!! and yet loads of people still use it!!!!

look at it this way why bother most of your vans heat. gose out the windows
iv seen vans rust from the inside out.

I WILL NEVER INSULATE A VAN EVER EVER EVER! its not worth it (get a better speeping bag)

I'll be fitting a headliner at somepoint and was wondering about fitting some scrim foam as insulation between the headliner and roof.

So would you not fit the insulation if you had to do your headliner again?

No, I've stripped the last of it out now.
The only thing I'll fit is some sound deadening strips.

That's what I have used - very effective and cheap (compared to the 'professional' stuff )

The problem with absorbent insulation (probably most types that are designated as thermally insulating) is that they do what they say on the tin - they trap pockets of air in order to do their job. The problem with using them in a damp environment is that those pockets of air contain a lot of moisture and over time it will condense and form droplets of water, which isn't going to go anywhere except pool in cavities.

Really, the only way to use this would be to seal it into panel voids - i.e. using some sort of plastic membrane over the top and ensuring that moisture cannot get to it. Or maybe even seal sections of insulation in plastic bags and then use this? If you have a dehumidifier, you could stick the insulation in a room for a week with it to ensure it is even more moisture-free before sealing it up.

Just my two pence worth.

What he said! But unless you know for sure that the cavity you are insulating is sealed from moisture entering in other areas, then let it breath! Just like in a house, trapped moisture leads to rot.

surely the insulation wont work in the bag, its trapping nothing , it's a pillow in a bag. :?

Sure it will - all you are trying to achieve is to stop the warm air from inside the van from getting to the (conductive) metal work and transfer to the outside world. The reason you have trapped pockets of air is to slow down the convection currents, or in effect create a barrier between the inside air and the panels.
