DIYer who followed a book to frame out my basement and left out fire blocking any suggestions?
1. Dow Thermax Sheathing was already on the walls so I left it there and framed next to it. What do I do for horizontal fire-block?
2. Had to frame around waste pipe not sure hot to fire block.
3. Left space for HVAC return air in framing, I cut the thermOpan and found that the return air for the existing connection goes through the floor.
4. Lowered bathroom ceiling do I have to add blocking inbetween each stud right below where the ceiling drywall will be?
Thanks for any help
