Ceiling Joists-2x6 vs 2x8 ?'s


Hello

I've got a 16' wide by 13' long area. Instead of using 16' long ceiling joists I'm using a build up beam (3-2x8or10) splitting it down the middle for extra support so I'll have 8' joists on each side. According to the span tables I can use 2x6's. Is there any extra benefit of going with 2x8's or is it ok with the 2x6's? Just drywall, no attic storage and I'll use No. 2 Pine. Thanks for your help.

Either way would work. No cost advantage to using 2x8. Some people love to over-build things, but if the 2x6 can handle the load then it would be the best option.

2 x 6's for the resulting 8' span are plenty adequate. You have to pay very close attention to keeping the bottom of everything flush at the built up beam, or you always end with an ugly ridge in the ceiling there. Remember, the bottom of the joist hangers have to be flush, not the bottom of the joists themselves. And be certain that all sheets of drywall span this beam, with no seams landing on it.

That's what I was thinking but just better safe than sorry. I'm think to keep the joist flush at the bottom just use something like a 1x6 say 6' long and use two clamps to hold underneath. Then just rest the hangers on top and nail in place. I could also mark on the 1x6 my 16" O.C locations for a quick setup. Thanks for the info and time.

Dont forget one advantage of taller joists would be how much insulation you can fit. I often bump 2x8's to 10's so I can use R25.
