Great information as always Steve. Can I ask, in regards to the dropped ceiling to accommodate lighting. Do you recommend this method for warm roofs too? Also how much of a drop do you recommend considering there may be water pipes as well as cables?
I’d really like to hear your thoughts and opinions on super foil and how it can be worked into a roof system with pir/rockwool between the rafters. I just cannot get my head around the u value calculation
I thought the Vapour control layer was supposed to be on the warm side of the insulation, seems to show it sandwiched between the across joist and the under joist.
hallejuja, somebody that actually understands, roof construction, insulation, ventilation and vapour control
Thanks
