Title: question about building a wall in front of my 10 ft garage roll up door
Post by: benstephen on August 03, 2015, 04:22:17 PM
Hi.  I have a 3 car garage and am using the one car space (16x14) as a band space.  I will be framing today and have a 3rd leaf question.  So far I have removed the garage door opener and the overhead tracks and have insulated and sealed up the garage door as much as possible.  But, it has almost zero mass.

I will be building a 2x4 framed and insulated wall  about 8" away from the existing wall that has the 10' metal garage door.   My plan was to face both sides of this new wall with drywall and fill with R13.

My question is will the existing garage door wall with the 10' wide roll up door act as a 3rd leaf and if so, would I be better off not using drywall on the side of my new wall that faces that garage door?

Hope this makes sense.  Thanks!

One more question:  Should I frame the walls at 16"OC or 24"OC? 

Thanks again.

No you will have to close the back of the new wall and make connections to adjoining walls.
Best thing to do is to build a second frame just for that wall and follow the double wall rules of open middle double insulation.  a room in a room.
Your outer frame in front of garage door you can do 16" OC but for the new walls inside of the room do 24" OC for less connection points.

Another question about building this double wall: "follow the double wall rules of open middle double insulation.  a room in a room."  When I frame around the garage door, do I need to wrap the frame around the garage door and mate it to the existing front wall, or can I simply frame up from side wall to side wall and from floor to ceiling, then fill with R19 batts and drywall the side facing inside the room? After that, I can always frame up another insulated wall a couple of  inches away towards the inside of the room to complete the "open middle double insulation."  Thanks again, Ben

Yes you can.. build the wall in  front of the garage door connecting to the existing outer walls.
Then build your new room inside.
