Garage Guide
I'm framing an existing garage area, now it's time for the ceiling, do I use 2 x 4 or 2 x 6's?
There are no floors on top the bedroom and bathroom I am framing in, there is the existing roof of the garage (that's staying put) So really, no one will be walking on top. However, it might be used as storage. So, can I use 2 x 4's or should I use 2 x 6's? Thanks

- what size is in the old part? go with same size as old part,
- you should probably check your local building codes. but most cellings I have crawled around in are 2x4 over the garage.
- If it isn't structural then it doesn't matter. But I would use the 2x6 if you are going to store anything heavy above the rooms.
- 2x4 s are good if you're not storing anything heavy up there.
- Using an undersized member will ensure the ceiling will sag. 2x4@16"oc. will span 11'8" 2x6@16"oc. will span 17'6" 2x8@16"oc. will span 23'3"
- 2x4's will save you money, however, they are not as supportive to hold storage and are not as sturdy. 2x6's will cost a little more, but may be worth it to hold your stored items, if they are heavy.
- Depending on the storage loads, the safe recommended span at 16 inch spacing is approximately 10 feet for 2x4 and 14 feet for 2x6. You can go to 24 inch spacing if the loads will be minimal but you should check the following link: http://www.southernpine.com/pdf/table17.pdf Courtlh
- If you are going to put any weight up there I would go with teh 2 x 6's. That way you wont have to worry if is gonna sag and crack the drywall onthe ceiling.
- With all due respect to you or any others who answer; I'll assume your garage is open to the roof rafters/support beams??? No matter the eventual use Rafters/Beams should probably never be considered at less than 2 x 8 and more likely at 2 x 10 for any OVER structure; IE: Stoarge/ second level flooring. Obviously that might also depend on code issues. Steven Wolf
