Today was a red letter day! The first wall went up. It is pretty exciting.
Dave decided to use screws instead of nails because he thinks they will make a sturdier wall. We are using a 24 on center 2 x 4 wall with the wood we took out of the original house walls. He used 3 inch screws to attach the top plate to the studs and to attach the wall to the furring board that he cut for above the wall. That board is screwed securely to the rafter above with 4 1/2 inch screws to go through the polyiso into the rafter.
This first wall is between the entry and the dining area and next to this short wall will be the inside doorway. It should be directly across from the garage doorway.
The walls are floating walls with a 1 1/2″ gap between the bottom of the wall and the floor plate. Then the two boards are spiked together with a 20# nail. I wanted to use double headed nails so we could be sure not to puncture the concrete but they may be a bit short.
