hi all, can anyone help,
Had a two storey extension shell built (over garage), the main side wall to the extension has come straight up off the garage wall which is 4" block with facing brick (no cavity).
In order to comply with reqs plans show the following spec,
Breather membrane to blockwork, 3x2 studding, 75mm dritherm, foil back plaster board.
I understand the principal of it however the breather membrane is causing me a few probs.
I can only find the stuff reccommended for roofing, is this ok?
If so I only need about 10mts yet some of the rolls seem to be 50mts and cost hundreds! is there a smaller product out there i cant find one.
Once i get my hands on the right membrane i,ve got to fix it to the blockwork any ideas on the best way of doing this
many thanks
