Jay, I plan on calling Steel Masters to ask if there’s a formal to determine how much weight can be hung from the QH arch. With the 2x framing, spray insulation, and then something to cover the insulation (plywood, metal sheeting, or my least favorite, drywall) I want to be sure I don’t do anything to compromise the structure. I would think that as long as the weight is evenly distributed it should support a fair amount of weight.
I know that covering the arch with anything (soil etc) voids the lifetime guarantee.
I know the large windows have a much lower R-value. That’s why I want to put almost all of them on the south facing wall. The back wall would have something (hempcrete?) for thermal mass, along with the concrete slab floor (bare, stained, and polished).
But yeah, I know all of this will add up to more than I’ll probably have after selling my current home, moving 2k miles, and buying a car appropriate for the rural mountains. That’s why I’ve been looking into prefab houses. Most are catering to the upper middle class buyer. But there are a few that are making what seem like nice, well built, but small homes. The kind we need in this housing crisis. If I can get into something like that and then take my time to build another house on the property. Eventually rent the smaller one out. That would take a lot of the pressure off me. The idea of selling, moving across country, then starting a building project…just the logistics of it can keep me up at night.
