Can anyone give me some examples of what contractors are doing for building envelope retrofits? I live in Climate Zone 4A (MD Annapolis area) and am interested to see what assemblies people are installing. I have a slab on grade house, but am interested in Zip sheathing with a rain screen. I’ve seen a few neighbors get their siding done: one of the contractors used what looked like Henry Blueskin right over the current fiberboard sheathing, another re-sheathed with OSB and stapled a reflective insulation shield.
I’ve read a lot about dew point and I don’t think a lot of homeowners are involved/interested enough to make sure they aren’t creating a moisture problem so I’d like to ask the experts.
Can anyone out there in the 4A area give me an idea of a wall assembly that has provided good air sealing and tighten up their envelope?
