Summer is almost here, so it's time for garage construction. I'm about to order 2 overhead doors and I'm planning to frame a new wall for these (currently have a building with wooden folding doors). What I need help with is the actual framing of the door wall.
If we take the wall construction from outside in (planning for about 190-195 thick insulation):
- White tp20 sheet metal
- battens
- wind barrier
- 145x45 stud
- insulation
- vapor barrier(?)
- horizontal 45x45 stud
I haven't decided on the inside yet, whether metal or plywood + gypsum... but we'll take that later. What do you think about a vapor barrier in a garage when you have metal on the inside and outside?
In the door instructions, it says double 45 studs, at least 95 wide on each side of the door. I'm thinking I should be able to place 2 pieces of 145x45 together, then one 145 with the wide side against the door rails? That should work, right? Attaching a quick image, viewed from above:
Should I bind them together at the top with 195x45 for stability, etc.?
How do I deal with the horizontal 45 at, for example, a door frame? Do you place a 195 thick stud, or end the 45 on a 145 stud? Is there a good website where I can read a bit more?
Or should I simply frame 195 and insulate 195 thick?
