🗑
|
||||

🗑
|
||||
| What is the disadvantage of using solid lumber joists in platform framing? | Shrinkage occurs in the width of the floor joists.

🗑
|
||||
| How are floors supported in balloon framing? | The main floor rests on the foundation mud sill. Upper floors are nailed to the side of studs and rest on a let in ribbon.
