I live on a end terrce house and as such my bedroom in winter is always really cold. I plan to batten the external wall and then plasterboard over, however I was also planning on putting some standard (loft type) insulation between the wall and plasterboard, however I have then been reading about making sure i have a water vapour barrier and the potential problems this can cause if i dont.
What would be the best course of action in this situation and do i even need to put down a membrane/barrier? I have lots of standard plasterboard left over so didnt want to go out and buy the foil backed one which i always read may help?
The other option is to not put any insulation in at all and whether this would avoid having to put down a barrier/membrane.. but then im wondering if this will even make the room any warmer?
All hints and tips appreciated! I dont have a clue when it comes to things like this!!
