Plywood sheathing for the small home plan

Small home plans make the job of securing the plywood easy because of their small size. This can be plywood or OSB. (Oriented-Strand-Board) It can also be
T-111 wood siding.
Sheathing not only encloses the framing, but it also helps make the structure a lot stronger by joining everything together as one unit. The walls and roof will need to be covered with sheathing after the framework is done. A lot of carpenters build the walls, then make them stronger by putting the plywood on before they start the roof.

I’ve seen several different ways of putting the sheets on. I really don’t think it matters very much anymore. This is the most common way of doing it. I say that it doesn’t matter because most homes are now sheathed with OSB which is made out of wood chips and glue. Actually, it is made of several layers of wood chips and glue, but the pattern of each layer is alternated to make the sheet stronger.

Start with the walls and put the first sheet so it covers the rim joist and part of the foundation wall. See pic


You will need to overlap the seams for extra strength. This will be especially necessary when doing the flooring. See pic.


You will do the same thing on the roof. The direction of the plywood doesn’t make that much difference anymore.

It’s probably best to cross the joists and trusses, but I’ve seen it done both ways. See pic

I just wanted to say that I love your website. My husband and I followed your instructions on building our own home. Most of the work we did ourselves, but not all. We saved $90,000 in labor costs and now have a beautiful home that we own.

I built my own home doing all my own labor. My house costs me around $70,000 for materials. It took me 8 months to build and is about 2,000 square feet. I didn't think I could do it, but your house web site encouraged me. I used all the info you had.

Thank you,

I can't thank you enough for your free information web site about home building. I was looking for Electrical wiring diagrams when I found your site. It was very helpful.

My wife and I lost our home to foreclosure but we kept a plot of land to start over. We are halfway through the construction of our house. Your website gave us hope to start over and build a house with low payments. We are in our late 60's but we find it rewarding to put so much effort into a project that will reward us for years to come.
