Inside the number of weeks that it took to set up the insulation and await delivery from the steel siding, there were a dozen or so uninvited friends inside our wall assembly.

Does “breathable home wrap” go among the baffles as well as the Rockwool? When that is certainly comprehensive added Rockwool is going to be put on top rated of the detachable pieces of sheetrock. Does your “good vapor retarder like Membrane” go higher than the sheetrock and down below the Rockwool? I will not hope this being a simple procedure, but if it will operate I’m up for it. The key purpose is to maintain the tricky-acquired natural air stream ensuing from now-Doing work soffit vents and also the re-recognized ridge vent.

That is a pragmatic strategy to make a superior overall performance setting up when There is certainly an existing inside poly vapor barrier that's tough to accessibility. Why battle it?!

As his entirely amateur assistant I used to be hustling like mad just to keep up with him, so thank you a great deal in your goal observation.

A caveat: As Some others pointed out, the fibers from both equally rock wool and fiberglass are irritating. Study shows they could also be carcinogenic, like asbestos fibers. So you don't want to breath them! Have on a superb dust mask - not the cheapos having a rubber band to the back. 3M can make good dust masks for development, available at HD and copyright. We also have on affordable Tyvek 'painter's satisfies' and gloves for greater jobs, to keep the fibers off of our dresses - and in order to avoid bringing the fibers house.

“It has an exceptionally modest obtain in R-benefit but I do like a few of the other Houses,” Wiscoguy writes Within this Q&A post. “Also, next to not one person in my region needs to make it happen, which pushes my schedule back even more.”

Waiting for insulating his new household, Wiscoguy claims he’s planning to use an R-fourteen layer of exterior insulation together with mineral wool inside the stud bays. But there’s a sticking level—Value.

You would not want to do that with a roof, but I'd consider using some form of ventilation baffles, possibly web-site developed (1/two" polyiso operates perfect for that), or a thing premade like Duravent.

Consider the ongoing case of Group opposition to mineral wool producing that may be unfolding in Jefferson County, West Virginia. Neighbors are asking: “Who bears the air pollution costs of producing ‘eco-friendly’ items?” The Tale was posted in March of 2021 in VICE Environment Information. (For just a dispassionate, scientific evaluate on the equilibrium amongst helpful insulating traits that make the mineral wool inexperienced in properties but an Strength-intense and polluting product to generate, consult with “Environmental evaluation of mineral wool manufacturing.

It really is correctly high-quality To place a true moisture barrier on the inside aspect of the concrete or CMU foundation. When there is a capillary split among the inspiration wall and wood Basis sill It can be high-quality to even use sheet EPDM or significant polyethylene in between the muse and insulation. (EPDM that will come up and excessive of the inspiration, beneath the sill will make a fantastic capillary split for both equally the sill and insulation.)

Many thanks for sharing your experience. Did you deal with basement insulation? Would the mineral wool panels be acceptable on the surface of the muse wall, over and underneath quality, to maintain the wall and basement inside warm?

Hello Fred, Sorry for hold off in reaction.... As equally Martin and Michael commented, there are mineral wool panels designed for down below grade ailments and given that the perimeter soil is properly-draining, this underneath quality mineral wool can be quite a very good alternate to foam products and solutions. Having said that, the job highlighted in this post was a deep Strength retrofit of the current structure and full excavation exposing the exterior Basis would have been required to set up insulation on the outside side of the inspiration - not a practical thing to consider on this tight urban website.
