Have a question and we think we know the answer but we want to double check cause it could save time and money.

We are going to be installing a 'cabin grade' about 5/16" thick pine bead board to our ceilings below our loft. The floor joist are 2' apart. Do we need to put up a furring strip first and attach to that or would the bead board span the 2' without sagging? I think the strips of bead board are about 4" wide and are tongue and groove if that matters. What are your thoughts and/or experience you could share? Thanks!

TB, are you sure the planks are 3/16" and not 3/8" or 7/16ths? 3/16ths is pretty thin for T&G.

No, I was wrong. They look like about 5/16. They are thin- they are meant for walls.

troll is referring to a bead board type of product if im not mistaken, I would put plywood up first then attach to the plywood, gravity always wins, also if someone puts pressure on the ceiling, without the plywood backing they could make a hole.

thats my opinion anyway, we have a similar decision to make , our lofts have 2x6 beams running across the lower floor, I think we may just stain and poly the beams and put either planks, or the bead board knotty pine in between them (not over them,but up in the ditch between)

Show us some pics with its done !

Thanks Rifraf! We thought about putting them between the joist also but in our situation we have a lot that are not evenly spaced and turn direction too. In our bedroom we are going to be putting up "faux" beams and then putting the bead board between them.

We will be going up again over New Years and though we don't want to bore the kids with working the whole time we do want to get a lot done. I'll post pics when we get a start on it.

If you do put plywood up, be sure you lay it across the joists, not length of the sheet in line with them, and stagger the joints to keep it more rigid.

I'm not so worried about having anything push through the wood-we have used the same stuff in our home on the ceiling in a couple areas in our finished basement. In those areas we have floor joist 16" apart. None of our kids(or their friends) have ever damaged it in any way, it is stronger than it sounds. We are thinking we would have to run strips of wood across the joist and then attach the bead board to them so it doesn't sag.

Drywall is really cheap -- one of my next projects is to insulate and rock my ceiling and then glue and nail cedar pickets on top --- yep I have 2 ft joists as well -- this will allow be to easily staggger the boards.

TB, i would strip across the bottom of the joist before putting up the T&G or put up a 2x4 between each joist even with the bottom to give you more to nail to.

TB, if it is a laminated product, you could probably get a lot of years out of it before it sagged, if it ever did. The biggest contributor to sag is humidity; so if your cabin is dry, it should last quite awhile. But, the best way would be like Bevis said. Run the nailers on 12" centers and shoot it up. If you really want to get anal, put a spot of liquid nail under each board before you nail it.:)

Personally, sheetrock will work, but it is too heavy to put up just for backer. The 1X2 nailer strips are cheaper and a heck of a lot lighter. Just pop a bunch of lines across the bottom of your joist and start nailing.

Thanks guys-you said exactly what we were thinking of doing so we will go that route. It may not sag- but I don't want to redo it. It does get very humid here and since the cabin is closed up when we are not there it tends to stay trapped, so that was a good point.
Thanks for the advice!

Great minds think alike! We're planning to do bead board on the ceiling of our bathroom. I think we're just going to get 4x8' sheets that look like actual T&G though. It's a small area and it's just to conceal wiring that runs through the area. I'll be anxious to see photos of yours when its in.

Here are pictures of what we did for anybody who may be interested. We did put up 1x3 strapping to span the joist and then the T&G bead board.
