I'm about to do this (fix the battens that is) but I've decided to bond them in with fibre glass. I realise I could use rubber seals around bolt heads and so on, I just don't want to start drilling holes in the roof. Anyone else any thoughts on this?
Guess you're looking at two issues....fibre glass is pretty brittle for drilling into (tho' I've seen other forum discussions on how to get round that) but then you also have to be able to attach something to it. I have no idea how it would take screws or fixings if you could drill a clean hole. I'm assuming your just talking about drilling into the interior panel of the roof, rather than right thru to the outside. I'd avoid that unless you can guarantee to make it water-tight.
I reckon Trevor's idea is a good one.....if you can find a way to fix the battens without drilling holes - impact adhesive, no more nails, fibre glass or....? Fibre glass does have it's own joys though, a mate who fixes his old slalom canoe says it can be hard to work with...be interested in what others think.
Not sure quite if anyone has tried this before, but got some old foam from a swiming pool,
Yes that's right, it goes between the pool liner and the base.
Wow it is good insulation, relatively easy to fit, possibly free, if you have a pool building company near by that is. The stuff I used was scrap from a local company, it would have been dumped otherwise,
its water proof too !!! so no membrains needed, also apears to be good as sound proofing!!!
Used a spray adhesive on bare metal and foam, its about 7mm thick so can be built up easily
Plan is to use PVA bond glue or double sided carpet tape to fix it to the back of the existing plastic lining panels and seal the join between the insulation and the van metal sides with silicone sealant to act as a vapour barrier.
Has anyone else tried this stuff ? It looks too good to be true, thin light and excellent insulation properties.
Also does anyone know where I can get some small windows 300 x 300 mm max to fit into the sides of the extended roof of My van, between the roof support frames. These will be at eye level when standing in the van, but too high for anyone to see in from outside. windows in the usual place, (in the side loading door and the fixed panel opposite this) are too low, waist level, when standing inside the van

Hi Guys an galls,
Not sure quite if anyone has tried this before, but got some old foam from a swiming pool,

Hope this helps

I'm planning to use this Airtec Double Insulation www.screwfix.com/prods/21112/Building/Roofing-Insulation/Airtec-Double-Insulation-1-05m-x-25m fixed to the back of the existing lining panels in My Renault Trafic, as it's only around 3 mm thick but gives the same insulation as 55 mm of polystyrene.
Plan is to use PVA bond glue or double sided carpet tape to fix it to the back of the existing plastic lining panels and seal the join between the insulation and the van metal sides with silicone sealant to act as a vapour barrier.
Has anyone else tried this stuff ? It looks too good to be true, thin light and excellent insulation properties.

Thanks,
