Can You Use OSB Sheathing For Interior Walls?
Yes, you can use OSB sheathing for interior walls. If you’re thinking of using OSB sheathing, you need to know where to use them. When you search for running ductwork through your floor, you want to know the uses.
But don’t you worry. We’re here to tell you exactly where you can use them. Let’s find out.
You can use OSB sheathing for both internal and external walls. But for this article let’s focus on internal walls.
The main purpose of internal wall sheathing is to precisely design the interior. OSB vs MDF can be two options for interior designing. But OSB boards can be utilized to achieve a modern and warm appearance. On the surfaces of OSB boards, you can also use paint or glossy varnish.
OSB can even be also applied in place of sheetrock for inside wall sheathing. This will reduce heat and cold conduction as a result.
OSB panels are also made of compacted panels with no gaps or holes. This makes them different from other boards.
Now you know about the uses of OSB sheathing for internal walls. Let’s find out how you can use them.
OSB Sheathing for Interior Walls: Step By Step Process
Installing OSB sheathing for your internal walls can be a lengthy process. We recommend you learn some woodworking tips before taking on this project.
To make things easier, we’ve provided you with the steps to do it. If you don’t follow our instructions, it can take even longer. That’s why let’s not waste any time.
To move on with your project you’ll need some special tools. Let’s see what they are-
- OSB panels
- Tape measure
- Chalk line
- Table saw
- Nail gun
Got them? Okay, let’s get started.
Step 1: Precautions Before Installation
Before you install your OSB panels for sheathing, you should follow some precautions. Just like how you need to follow the precautions before tiling around a floor drain. These precautions will save both your time and money.
Prior to installation always check for crooked or improperly installed studs. These can lead to problems in the future.
For example, you’ll get uneven walls and siding. You should take time to ensure all the studs are straight and square. You’ll also end up with a far better result.
That’s it! It’s time to see the steps for installation.
Step 2: Draw Lines For Proper Spacing
Once you’re done with precautions, draw the proper lines for installation. This is an important part. Your full installation will be based on this part. We suggest you look at your local building codes before drawing.
Perimeter fasteners are normally placed 6 inches apart in the center and along the edges. Make sure they’re placed 12 inches apart on the center portions of the panel. But closer spacing is always preferable.
You should place fasteners by leaving a ⅜ inch gap from the panel edges. Always remember, each corner requires a fastener. You should draw lines and dots using chalks according to these measurements.
Step 3: Set Nails For Support
Before installing the OSB sheathing, set a couple of nails into the floor framing. Do this by using a hammer. This will give your OSB panels support and spacing. Let us explain how-
The OSB panel can rest on the nails while you square and level it. Make sure the entire wall has nails for support.

Step 4: Attach The First OSB Boards
Start with a full OSB panel. Make sure the grade stamp is facing the inside of the structure.
Ensure the fastener guidelines are facing the outside. These guidelines should be spaced every 16 inches and 24 inches. This makes lining up with studs easier.
You can now begin nailing down your OSB panel. Start with the corner. Make sure all the fasteners hit the framing member behind.
You should have a quick check from inside for shiners. If you find any nails that missed the framing, add some extra nails.
Remember, you should never overdrive or underdrive the fasteners. Your fastener’s head should be flushed with the surface of the panel.
Step 5: Attach Other Layers Of OSB Boards
When you’re attaching the second layer of panels, make sure they’re not tightly attached. You must place the panel edges ⅛ inch apart. This gap will save your panels from moisture and humidity.
Once done, repeat the process you used to support your panels. Put a couple of nails into the floor panel as you did in the previous step.
Don’t forget to space the joints ⅛ inch apart from each other. This can be easily done by putting a couple of nails into the studs.
Make sure to stagger the vertical joints. This way the second row panels counterbalance the first. This means the first panel on the second row will likely be half a panel.
Repeat the process once again until your whole wall is covered. The spacing will be the same as before.
Step 6: Remove The Nails
When all the panels are fastened, remove all the nails you used for support. Do this part carefully because you might cut yourself. You might even step on a nail. That’s why be sure to wear boots while working.
Step 7: Cut Out Openings
Sheathe the entire wall before cutting out the openings. This will be an easier and more efficient way to build.
Question: Can 7/16 OSB be used for garage walls?
Answer: OSB is an excellent garage wall sheathing material. It’s sturdy and long-lasting. It may be used to nail or staple insulation to garage walls.
Question: Is OSB stronger than plywood?
Answer: In shear, OSB outperforms plywood. Shear values are approximately 2 times more than plywood due to its thickness.
Question: Is OSB water-resistant?
Answer: Yes, OSB is water-resistant. Every fiber and particle of wood in an OSB is drenched with a resin mixture. This ensures excellent strength. As a result, the end product is waterproof.
OSB sheathing for interior walls, now you know how you can do it. Keep in mind that this is a long and hard project. If you’re not sure you can do it, contact a professional.
We wish you all the luck in your DIY project!
