Edge strip insulation by JGUHEDGE or similar approved - My builder used this, the architect specified 25mm PIR. This thin insulation creates a bad cold bridge. i am doing this job now too, i have done a 25mm PIR insulation, but i think that the foam around the edge is for expansion, not for the insulation, and goes in after the VCL membrane Link to comment Share on other sites More sharing options...

It excludes alarm/cameras so as before I'd love to see an actual quote but it's not unreasonable I think If you think it will help 👍 Elec.pdf 1 Link to comment Share on other sites More sharing options...

Regards James Historically builders just used the 8mm strip. You need the PIR too to reduce cold bridging Link to comment Share on other sites More sharing options...
