Looks like the bathroom wall gets it this weekend. As I mentioned before a while ago it's a single brick edwardian/victorian addition so I have the following
Polythene sheet membrane, 34 x 34 batons, 25mm polystyrene sheets for between batons and pine cladding for top surface.
Should I hang the membrane up first then fix everything over the top or put the battons & insulation directly to the wall then cover with membrane and clad over?
I's not a mission critical job as anything is going to be better than was there before... fluffy plaster and a big sheet of chip board as insulation it might seem.
Cheers Pete
