Interior Framing Interior Framing — Interior framing in a Monolithic Domes is not that much different than in conventional buildings. We have wood studs for the exterior that have been insulated with polyurethane foam, and metal studs for the interior walls. (David South Jr.) Inset openings — This is dome was designed with inset openings that were framed in after the dome was built. (David South Jr.) Electrical — Electric lines are run throughout the interior walls just like standard construction. (David South Jr.) Extra studs around doors — Wherever we are going to mount an interior door, we line that with wood studs. The wood studs give us a sturdy area to screw to. (David South Jr.) Steel stud — We prefer steel studs inside the dome since they are so easy to install. They can be easily cut with scissors, then screwed into the concrete shell. (David South Jr.) Just before sheetrock — Here’s the wall after all the studs, wire, plumbing, etc. (David South Jr.)
