Thanks to the reply. Your house grade is significant ample which the h2o table is underneath the footing and would even be beneath the sump. There’s a good hill in my back again yard sloping all the way down to the swampy area. I’d say maybe twenty ft elevation variation. That’s a good issue on The position with the insulation. I’ll take a look at that additional but creating a handful of assumptions. The way in which the insulation is Ordinarily mounted is by capturing a nail and plastic system through the board and in the wall.
A few of this information described down below, you most likely now know, but I’ll describe just in the event you haven’t considered A few of these potential difficulties and alternatives. Sorry when you now know this, or its also specific or complicated. Deteriorated wall sheathing may very well be owing partly to condensation of drinking water vapor that escaped from the home’s interior, via tiny holes and cracks in your walls, then condensed with your sheathing. Usually, this moisture would evaporate afterwards as temps heat up. Nevertheless it’s a probable reason for wood sheathing rot. The solution is to produce the partitions extra airtight. When you put in Zip-R or other substitution sheathing or exterior insulation, the sheathing edges really should be taped, and window edges should be sealed airtight for the bordering sheathing. If minimal air migrates by means of your walls, there will be little or no condensation.

Lower-Strength structures usually demand demanding air sealing, but this task was noteworthy for The weird constructing enclosure factors plus the recognition that exterior rock wool is a wonderful Remedy for “vapor-out” assemblies.
We renovated 2 rooms and insulated the outside partitions with Rockwool Comfortbatt R15s. I actually such as the rigidity and density on the Comfortbatt goods and am seeking to plan the top approach for an attic install. The rafters and joists are 2×6 lumber spaced 16″. I realize we have to enable air flow though the soffit and should insert produced or diy soffit baffles.
“Depends on the quality of the installer,” he states. “If you can strike Quality one with fiberglass batts, then move on the mineral wool.”
Mineral wool was once 50% a lot more than fiberglass but it appears that evidently now - While both have amplified drastically in the last handful of a long time - the previous is nearer to double the price ( R13 vs.
Another issue, if your attic incorporates a hatch, or pull-down stairs, you'll need to ensure that is just not an enormous gap during the air and thermal obstacles. Here is some extra info on that:
Vapor retarders go to the "warm in Wintertime" side when you are inside a heating dominated weather, so among the insulation as well as the drywall. Using a thing like housewrap on the other (attic) side with the insulation the place the insulation would otherwise be exposed over a vertical wall really helps to limit convection currents from cutting down the R value of the insulation.
In case you examine in the various content articles on GBA, you may get an concept of most of the standard concepts that will allow you to to grasp wherever points really should Select very best performance. You may always inquire in Q+A way too if you get stumped of In case you have a problem that does not very in good shape any of the illustrations from the article content.
The rationale is the fact that whilst mineral wool features a slight edge above fiberglass in acoustic transfer within a head-to-head comparison, the instant you put in both into a wall, it click here gets to be the the very least vital A part of that assembly Which slight edge is erased.
Many thanks for sharing your encounter. Did you tackle basement insulation? Would the mineral wool panels be appropriate on the surface of the foundation wall, previously mentioned and down below quality, to keep the wall and basement inside warm?
When creating a 3D model on the framework I found an R15 batt put in alongside the rafters could retain an air hole of 2″. However not expected by code, I started to speculate if insulating between the joists and rafters would create a more efficient system.
