Hello,
Award prestige. single axle.
Problems
All timber is rotten
Cracked windows
Seals gone all around and none at all at rear.
Well i've ripped it pretty much all out now. A solid days work split over 4. Well i tried to keep the internals as best i could at least to use them as templates..
My intentions were as follows:
Strip EPS insulation and replace with 25mm XPS.
While stripping, I noticed one pannel of insulation had been replaced by what looked like the residue of a PU foam type adheive. However the damp seems to have attacked the foam and the pannel just full out when i touched it. Other panels are firmly in situ.. So....
Qu1) Which adhesive should i be using?
Something like this? http://www.thegluepeople.co.uk/v1/html/tradepur_ltm8.html
So walls and floor will be 25mm XPS. Currently between roof panel/ceiling and roof is the horrid fibre glass. Is there any reason this is used? Obviously it allows for breathability but its not as iff water vapour will get far given there's metal on the other side.. What about XPS insulation there also. Ok well i 'll confess i do have quite a bit of it hanging around.
So as I said its stripped. ok i could replace by treated timber but even that absorbs water and goes damp and musty.. My thought was to use something called EKOply and cut it into strips. aprox 19mmx25 (match the insulation)
Qu 2) Has anybody come across ekoply? Any thoughts on pros and cons of it? Ok its far more expensive than timber but it shoudl never rot..
While stripping i noticed that not one join was water tight.. none zilch. Clearly i have to clean strip and re seal all these joins.
So qu 3) What are the sealants to use?
i) where fibre moulded panel meets alu. Currently at the rear nothing is there at all.. it just flaps (well with a little force).. .
ii) Where alu meets alu. Some sections have 25cm huge overlaps
HP600 Strip Sealant
And I presume I use it both sides? And in between also?
iii) Around window/door seals?

or SIKAFLEX 512
Wall and ceiling covering.
Not too sure here but budget and removing damp or permeability through to the skin. I came across this. 3mm PVC board.. Ok so not the prettiest but i'm presuming that somebody could wallpaper over.

I'll leave it there for now,.. Any pointers would be greatly appreciated.
