Err, the FIRST thing I'll do is get that box of plastic cable staples and tidy up the NM cable as per your suggestion. The do the job the thing is while in the photograph was for the very close of my electrician's week, and he was very fried.
If it DID get installed at the location revealed from the depth (at the top of the bracket) what was it intended to accomplish?

Reduced-Vitality buildings often demand rigorous air sealing, but this project was noteworthy for The weird making enclosure parts along with the recognition that exterior rock wool is a superb Answer for “vapor-out” assemblies.
“I generally choose cellulose for its low-carbon factor, but with mineral wool and fiberglass having related amounts of embodied carbon, I don’t see a cause to prioritize mineral wool.”
The batten strips marginally compressed the rock wool panels and held the insulation set up as we ongoing to stack it. Because the insulation went up and absolutely wrapped the two-story dwelling, I marveled at how snug the continuous rock wool wrap built the composition seem, like the thick wool comforter that might have retained us heat in more simple occasions.
Chris had held off replacing the exterior wall finishes of his residence, as he hoped to develop a 2nd-flooring addition on an current one particular-Tale part of your home.
Chris was aiming to realize a higher-functionality, reduced-energy dwelling, nevertheless he comprehended that his early transforming selections constrained his options transferring forward. Just one of these limiting conclusions was the installation of a polyethylene vapor barrier on The within encounter of his exterior wall framing as he gutted and remodeled Each individual area.
This could puncture the vapor barrier and allow moisture to penetrate. Also putting the vapor barrier ahead of the insulation may well cause condensation forming on the inside surface from the barrier In the event the dehumidifier were to are unsuccessful. Probably not a tremendous chance but just one the pros take into consideration? I could see they there could be gaps in between the insulation and barrier leaving a surface for that condensation to type. Do they make rigid foam with a good hearth ranking? I’ve not viewed that and would eradicate certainly one of my bigger fears.

Is definitely the intent to guard the penetrations produced by the fasteners through the WRB? It won't manage to make sense to "flash" the tops of All those brackets as They're dealt with and should not be an issue
I am glad the Heco Topix Therm worked on this project. I remember the mineral wool thickness was proper at the sting of your running selection in which it would not compress the MW. It would not audio such as you had excessive difficulty.
Hello Fred, check here Sorry for delay in reaction.... As both equally Martin and Michael commented, there are actually mineral wool panels suitable for under grade disorders and given that the perimeter soil is very well-draining, this under grade mineral wool is usually a good alternate to foam goods. However, the challenge highlighted inside of this article was a deep Vitality retrofit of an existing structure and comprehensive excavation exposing the outside foundation would've been necessary to put in insulation on the exterior aspect of the foundation - not a realistic consideration on this restricted city web site.
