Single story extension built with vaulted ceiling all approved building
In colder weather noticing a lot of air blowing out of holes in plasterboard
(cut out for sockets)
Roof construction: tiled, waterproof membrane, air gap, 90mm celotex
Wall plasterboard is dabbed all over so I assume air is coming in at roof
area and down walls.
Have read Kingspan insulation giving installation details of continuous
board adhesive top and bottom of plasterboard, is this standard or build reg
Any info on this appreciated.....
