We’ve watched your video on u-tube and wonder if you could give us some advice please…. roof insulation between joist
Last year we bought a barn that was converted in the 1980’s. It already has foil-backed insulation in the roof but only 35mm and we would like to increase this – without taking the roof off, as it’s simply too expensive.
Is this the right way to approach things or will we have a problem if we don’t put in a vapour barrier? Does the foil on the Kingspan work as a vapour barrier?We would really appreciate any advice.
Thanks very much,
Thanks for the email
Hi I’m going to be posting a video shortly addressing this problem, however haven’t quite got my mind around just how to do it because there is the way correct way and a way of doing this that you may get away with! I can’t advise but can try to explain both ways and then its down to you.
