I'm affixing 50mm PIR on a low brick wall and I plan to glue the boards to the wall first then batten on top with 25mm battens and mechanically fix through.
There's quite a few options for fixings - hammer/frame fixings, rawl+long screws, and various fixings that don't need a rawl. Prices vary a lot too. Just wondered what people prefer and why? What length of the fixing needs to be in the brick in my case?
