Mineral wool retains its shape much better than fiberglass or cellulose. It will not likely settle in just partitions, leaving chilly gaps alongside the best plate. If there’s air infiltration, dampness is not going to compromise or degrade its thermal general performance; and the fabric gives no food items to help microorganisms.
Nevertheless I am able to’t picture company like roxwool with all their money and investigate would advocate something that would generate a difficulty. But who understands ?!? I’ll Call their science Division and report again right here .
It is a pragmatic technique to develop a significant general performance creating when You can find an present inside poly vapor barrier that is hard to entry. Why combat it?!

Given that I fully grasp the key benefits of rain screens and also a drainage airplane/air flow driving the siding - many inquiries/feelings come to brain:
There is not any vapor barrier/retarder on The underside facet of the sub flooring. Will setting up the mineral wool insulation then implementing a vaper retarder (painting) the insulation be a difficulty for dampness? We reside in zone four. The basement walls are insulated.
The batten strips somewhat compressed the rock wool panels and held the insulation in place as we ongoing to stack it. As being the insulation went up and thoroughly wrapped the two-Tale dwelling, I marveled at how snug the continuous rock wool wrap manufactured the construction look, similar to the thick wool comforter Which may have stored us warm in less complicated periods.
In addition to a positive connection to the existing wall plates we were capable of remove the structural hundreds on the existing two×six roof rafters, which were being both structurally undersized and unable to manage A great deal insulation within their restricted depth.
Ultimately, mineral wool and fiberglass have COMPARABLE acoustic traits and therefore check here are far more similar than They're various.
Vapor retarders go to the "heat in Wintertime" facet when you are in a very heating dominated local climate, so involving the insulation and the drywall. Making use of anything like housewrap on another (attic) aspect of your insulation where the insulation would or else be exposed on the vertical wall helps you to Restrict convection currents from minimizing the R value of the insulation.
Rock wool On the flip side will wick moisture towards the moisture & mildew-susceptible end inside. The rock wool has to dry towards the inside, the foundation would not. So putting a drain aircraft material that may be also vapor retarder among the concrete/CMU as well as moisture-wicking fiber will not damage, and will even be important when there is Significantly floor humidity which makes it into the muse wall.

utilizing the batten approach with 1 x four or one x 3 vertical Wooden/plywood - how can we avert hornets/wasps and so on. from making nests During this Place, and/or would utilization of one of several rainscreen items available on the market work likewise for reasons of drainage/air flow -- and if so, are there any that you choose to (or Other folks) may advise?
That makes sense for stability. I dislike to tug the 1999 double panes out as They can be silicone caulked in place And that i'll need to someway make space for your deep window buck (want innies) to incorporate two extra outer layers of insulation (outdated 2x4 partitions in NE WI are COLD).
