ah OK, so you have stud work fixed to the wall, PIR friction fitted between them then battens fitted on top of the PIR for a service voice, and thin PIR around cabling. RE polythene, do you install this on the cold side of the insulation i.e. on the wall or the warm side (under the battens).

cheers for this - i'm starting to lean towards using standard PIR, seems to offer more flexibility and with some dormer work we are doing it reduces the number of different products we are using.

cheers, we're also dealing with a cavity, but we want the flexibility to be able to fill is retrospectively. alot of conflicting advice on the best way to secure! thanks for sharing

sorry to be slow, but I'm a little confused - if using PL4060 (insulation plasterboard) where would i put the 25mm PIR? Or are you saying best to go with PIR/batten, run cables then add 25mm PIR around cable runs?

got ya thanks, so meticulous taping is key. you're not the first one to have said that! just re-reading your post though, how would i fit the battens between the plasterboard and the PIR as PL4060 is a laminated product? Is it best to go for a traditional PIR, batten then board (thus creating...

Cheers - sounds like a similar setup to @noseall. Would that not potentially cause condensation issues behind the PIR as the walls are unlikely to be perfectly flat? Or could I save myself some work and do this mechical fix on top of the exisiting plasterboard? Also, I'm assuming a fixing depth...

Hi, Firstly, I've done ALOT of reading on this subject already so I come to this with some knowledge, however, as I think many of you who are reading this for answers have also experienced, there are many different opinions on the best way to install. Our setup is a unfilled cavity (approx 50...
