Condensation and mould :-(

Hi All,
Last summer, I decided to order myself a new headlining from lasalle trim to tidy up the inside of the beast. It's made of hard fibreglass. With all the cold weather of late, I noticed that I'm now getting condensation forming on the inside of the headlining and that has now started turning into mould :(. The mould has also spread to my new exmoor trim lock and fold seats in the rear.

Also, when I go round corners I'm noticing that the condensation must have pooled inside the headlining and it is pouring out of the sides and the holes where the radio box lives :mad:.

So it looks like I'm going to have to take the headlining out and power wash it to remove the mould :doh:.

Has anyone experienced this kind of problem? Do you think if I put some glass-wool (loft insulation) in the cavity between the roof and the headlining that the condensation problems will be reduced? It's really very annoying because the headlining was a bitch to fit.

Cheers.

Not sure, but Ive read about folk sticking foam camping mats to the inside of the roof to reduce condensation.

Despite the condensation, how do you rate the lasalle headlining? Ive often considered one myself.
 
I thought the lasalle headlining was great until the point when I started getting this condensation problem. It certainly made the inside of the beast look a lot more tidy.
I also thought that the ability to power wash it was going to be useful if the inside got attacked by mud at an off road site.

Prior to buying the new headlining, it had the dirty original one in the front but nothing in the back and I used to get condensation dripping from the inside of the roof in the cold. When I fitted the lock and fold seats I thought that I'd better get the headlining fitted to stop the condensation dripping on the seats. Nice idea, shame it didn't blooming work!
 
I think we all suffer from condensation problems, drippy unlined roof etc. I just had a look on google... seems you can get moisture absorbing crystals from Homebase for £5 and they last about 5/6 weeks. If you have aircon (ho ho) then this apparently take moisture out of the air.
I wonder if the front vents got left open a touch when parked up this would allow air to circulate and reduce moisture more? Even better if one or two suitable vents could be fitted at the rear above the door? Just a thought, if the roof on your house was airtight you would have mold and rot within a year... needs to breath
 
i think the problem is that your head lining is not in contact with the roof, if it was condensation shouldn't form on the metal surface.. well because there will be no room for water or air! i doubt you will manage to get it to stick perfectly to roof so as already mentioned try some insulation, ive heard of using camping matts too- cheap, thin, and easy to stick up. im gonna try them on my 90 hardtop soon!
 
Dont use "glass wool" loft insulation as it will act like a sponge and nothing will ever dry out.

I'd use some of the polystyrene stuff you can buy in different thicknesses and stick that to the roof before you put the liner back in. You can get an 8 by 4 sheet of 12mm thick stuff for less than a fiver in your local DIY place. It worked on my steel garage roof so no reason it wont in your motor.
 
Thanks for the suggestions guys - I'll go either with the camping mats or the flooring underlay depending on what I can find cheapest and will stuff a couple of layers in when I take the headling out to wash the mould off. I think there's about a half inch gap between the headlining and the roof itself so maybe even 3-4 layers will fit.
 
I've a Lasalle headlining in my 109. I got terribel condensation, bt that not Lasalle's fualt. The headlining does funnel it to the front which is good! And the lining went from a speckled limestone as supplied to a murky durge. it adds what they call in the antique trade 'patina' Now its an heirloom.

I fittd my lining in summenr, but teh wife bent my ear, refitted a few winters later with underlay. Much imporved. But roof leaks too, so I live with it. Not a lasalle problem, their stuff is good. My roof on the other hand...

Try fitting a Flettner 2000 rotary roof vent - it should work a treat!
 
I have the LaSalle headling as well but i shoved in some noisekiller on the inside of the roof then shoved some foam matting in too. More than likely the foam will be soaking up the condenstaion and in time it will be all furry in there. The good thing from that I guess is it might make it a tad quieter maybe???
 
On the camper van forums they put a silver insulating foil from BQ gaffer taped on.
I plan on sticky backed noise killer,then the silver insulating foil, then a head linning.
