Obviously you glue and nail the ply (or OSB) subflooring to the floor joists.
But what about the ply for the walls and roof?
Maybe I'm missing something but I dont usually see anyone using glue and nails for the ply on their walls. Is there a reason?
Is there any downside to also using glue?
Thanks...Paul
The glue will help stop squeaks on the floor. The walls generally don't squeak from the wood on wood contact. Once you have exterior sheathing up, interior wallboard, I would think the sidewalls are plenty rigid without the need for glue. Downside would be if you ever wanted to make changes, it would be extra labor as you need to cut it out. It also may affect vapor barrier - you want a breathable (even if well insulated) wall.
It could greatly increase racking resistance in the brace frame on a wall but generally more than one in a small house would be overkill as even one glued frame is not usually necessary if the bracing section is properly nailed.
Hurricane or high wind areas could benefit but will usually be prescribed by an engineer.
