I used this supplier, I have flat doors with an oak veneer and a bit of detailing. Very good quality and finish and they will make non-standard sizes with a...

Unless you *are* careful with whatever membrane you use, the house will be draughtier. It depends how concerned you are about your heating costs and CO2...
... Not necessarily. NHBC has reported many complaints from new homebuyers about I beam floors flexing too much. Just because they are silent, it doesn't ...
I have a ground floor with both solid concrete and suspended wood joists over open air. For the wooden joists i need to insulate. I am putting Celotex between...
The foil will only act as a radiant barrier, so will not stop conductive losses by direct contact. An impermeable membrane will stop draughts which will be...

Thanks for all feedback. I will proceed cautiously with the oak - and try one room for a few months. The house is being renovated to latest insulation levels ...
