Hello all,
having all the house plastered at the moment, before the porch is plastered i would like to insulate it as it is now part of the house but made of a single skin.
As the porch is not that big (2m x 1.5m) i was going to glue 100mm thick celotex (already purchased) against the wall and then glue the plasterboard onto that.
Ive chosen 100mm thick as it will blend into a double brick column that goes around the door so when its plastered you wont be able to tell its not a double skin wall.
Having now researched it i think it will be better to stud wall it and use the insulation in the gaps (as i have done on another larger wall)
What i am concerned about is i have read that a vapour barrier is required?? what is this vapour barrier and where does it go?
Is this the best way to insulate a single skin wall?
Many thanks
Robert
