We are having the loft converted to provide more living accomodation.
Box style with flat roof at the back and pitched roof at the front.
The sides are being done with celotex but parts of the pitched roof
are being done withwool and covered with plasterboard. There seems
to be a max of 3 to 4ins thickness of the wool. Should we be looking
to getting a greater thickness or asking for celotex instead? What
sort of vapour barier would be needed?
With regard to the flat roof - there are 6in joists with an angled
piece of woo atop each to provide a slight runoff angle. What sort of
gap or barrier do wee need here and would a double thickness of
celeotex be used here? (The stuff they have at the moment is 3ins
Sorry if this is basic but it is new to me and I want to get the best
job done now - the pitched roof in particular is north facing.
