The Ceiling

The roof of our sauna is built backwards. That is we first installed the ceiling, then the vapor barrier, rafters, insulation, plywood and shingles. All from the outside!

The important part here is to do both sides at the same time. This way you can keep the tendency of the ridge pole to warp to a minimum. If you do one side then the other, the ridge would slowly be pressed down and out towards the unfinished side ultimately leaving you with a noticeable bow. By working both side together you not only can keep this from happening but you can also check to make sure everything looks good on the inside. You don't want one side racing in front of the other so that joint lines don't match up from one side of the ceiling to the other. You can see in the middle picture I started in the center of the ridge and worked out towards both ends. This cuts in half any problems that may enter from boards drifting.

Here you can see the porch end and see that we've trimmed off the tailings at the eves. All that means is that each 2 x 6 ceiling board wants to run longer or shorter than it neighbor. After all the boards are fastened we trim them all the same with a skill saw.
