Garage wall refurb

[akpingel]

My house was built in the 70s and it is time to refinish the original garage walls. They were junk fiberboard and had many holes throughout. I pulled the first wall out and cleaned up and I've got a quick question.
Should I add fireblocking to these walls or is that a waste of time? I have r13 leftover from my shop project and plan on putting that in and covering the walls with OSB.
Any other suggestions while I have this apart?
Thanks,
Alex

When I did this project a few years ago I caulked every joint from the inside and filled the walls with rockwool insulation. It made a huge difference in sound transmission and temperature control for that end of the house, especially the ceiling which is the floor of the bedroom above. Rockwool won't burn and I used the fire rated 5/8" sheetrock per code for my area so fire resistance is hugely improved.

Run wiring now for additional lighting, speakers, tv, cable, internet, additional outlets, etc. for a clean look when it is finished.

Fireblocking + osb = more fuel.

Roxul + Type X = more flame resistant. Check for Type C which is even more fire resistant especially on the ceiling.

Forget the fireblocking. Insulate it, drywall it, and paint it to whatever color you desire.

Any insulation is better than none.

This is a perfect time to add the wiring that somebody else left out when they built that garage.

Good call about code. I blanked on that and I may not be able to use OSB here. I went straight to thinking about getting rid of the flimsy fiberboard for something more rigid.

My entire shop is OSB over R-13. No issues.
