With the cabin beams in place, it was time to install the cabin floor joists. With only a ten foot span between the beams, we didn’t need to use engineered joists. We then discovered that engineered joist was cheaper and easier to work with than dimensional lumber. So that’s what we decided to go with.
The rep. at Nelson Lumber had a reference book to size the engineered joist based on the span required. The original plans only had two beams twenty feet apart. We decided to add a beam in the middle. With only a ten foot span even the smallest joist they had was way more than we needed.
As with most of the material we used, we decided to use larger or better. Go big or go home! Instead of OSB be went with plywood. If 2×8 was recommended on the plans, we went with 2×10’s.
At the time we purchased the material the difference in cost was not substantial. I would rather err on the side of caution. Better safe than sorry!
Help with the Rim Joist
After all the joist were in place, mom and dad showed up to inspect our work. We managed to put them to work installing the rim joist.
Now we just need to add the vapor barrier and pick up the plywood for the sub floor.
