I intend on encapsulating the crawl utilizing a dehumidifier. The residence is near a marsh and therefor the bottom is pretty wet so I is going to be installing a drain and sump method from the crawl. I was scheduling on setting up foam board in opposition to the brick Basis then sealing using a vapor barrier.
About 50% more expensive than fiberglass or foam, mineral wool can be disagreeable to operate with. You have to use protecting equipment when putting in it since the little mineral slivers will lodge into the skin and lungs; the particles inhaled can irritate the alveoli.
We nonetheless wanted to determine the best way to mechanically fasten six inches of rock wool to the outside of the house. We wanted a system that would aid the vertical load on the insulation and the siding along with horizontal lateral masses exerted by wind forces.

You clearly know a whole lot concerning this insulation/vapor barrier difficulty, And that i Evidently know not a great deal.
