Have you investigated Renotherm? http://www.renotherm.co.uk/ I'd be
interested to hear if anyone has used this company or similar.
I wouldn't touch it with a barge pole.
If you put that into your loft I wouldn't buy your house.


OK, I'll bite. This stuff has been around now long enough to show any
bad effects - have any been seen in the flesh?

My (rented) place has the attic done like this. Seems OK so far, but
then again I don't know how long it's been in place...


I presume the issue is condensation/rot in the timbers?

I might be paranoid, and wrong, but I don't need to take the chance.

When this is on the inside of the tiles the condition of the timbers
cannot be assessed. It's been used because there is some kind of problem
with the roof, and it hides whatever the problem is. That's enough to
put me off.

Their website has a Q&A section that states
Q. Does Renotherm trap moisture in the roof timbers?
A. No, Renotherm does not absorb water but it does allow water vapour to
pass through the foam, at about the same rate as wood itself.

Q. Can alterations be made in the future?
A. Yes, the foam can be cut out and the tiles removed. Small areas can be
re-foamed with a Foamseal pack.
