I'm about to start insulating our external walls, internally. I plan to use the "warm batten" method. I.e. sticking PIR to the wall and then mechanically fixing battens through it.
The walls I'm tackling first and back to brick, so far from straight/plumb/even, which is complicating matters. Do I just apply enough spray foam to adhere the PIR straight and plumb and let some long screws through the battens take care of the rest?
What alternative methods would you recommend?
