Wall OSB Sheathing and Tyvek House Wrap [Build a Workshop]

Placing OSB on the exterior walls of your shop can greatly increase the strength of the building and helps to give a surface to attach the wall siding. I am using 1/2" OSB on my walls. Each stud behind the OSB is getting screws to make sure that the building is strong. After all the sheathing has been installed I install Tyvek Home Wrap. This is a material that repels water droplets while allowing vapor to escape. Tyvek tape is used on seams and gaps to adhere the sections of tyvek together. Nails are acceptable to install the OSB but I like to use screws.

you should have started the sheathing on the bottom rim joist to tie in the floor system with the walls

I just sheathed up a 16x10 and its was alot of work so I can appreciate how long this would take to do solo! Especially when taking the time to record, narrate and teach along the way. We just put on the common rafters for the 8:12 slope roof, .. we did all the math on paper and thankfully the birds mouth and ridge board fit like a glove. First build since I worked as a laborer for a general contractor ~20 years ago in high school. Cheers!

I built a Tyvek wrapped OSB house. We taped the edges and then covered it with hardi plank lap siding with a 1/1/4" overlap. All the butt joints were caulked. Later we had to move some windows and removed the siding. Every nail hole had a 4 to 6" wet spot behind the Tyvek. Turns out that all it takes is 20 mph wind driven rain to climb that overlap. We get a lot of that in my area. Water was running laterally on the top of each course of siding and running down over the Tyvek at windows and edges. The OSB beneath the window corners was soaked. The water went through the lap siding nail holes and was trapped inside. It wouldn't evaporate out of the holes it went in through. The lower sections had whole sheets that were completely soaked. I never used either OSB or Tyvek again. I switched to cdx, 30lb asphalt paper and a 1 3/4" siding overlap. Not the Home Depot 30 lb crap but the real stuff from a roofing supplier. That paper seals the nail holes and keeps the water out. If any does get in it can evaporate out. Tape your windows good and that plywood will last 200 years with lap siding over it. Engineers schmengineers. They've made a lot of garbage and sold it as upgrades.

Why didn't you stagger your OSB seem? Wouldn't that make it stronger? Just asking. Keep up the great work.

[BrittCHelmsSr]

Nice job with all of the sheathing and Tyvec.

[tomamundson]

Your vertical seams are supposed to be staggered down the wall. You should never have 4 corners meet at a singular point. Otherwise looks great!

[lonnieclemens]

I admire your ability to work by yourself. Thank you for sharing this video.

[Tibs]

Thank you, you weren’t kidding when you said solo! Good job! Can’t wait to learn more from you, if there was anything you could change as hindsight is 20/20, what would it be?

[joses]

I just did my shed, did smooth side out and put pencil marks for studs which allows water shed if any gets below the tyvek. Also did upright so seams shoot down in case water gets in under metal siding and tyvek and does not siphon it in if horizontal OSB run on walls.. also a pneumatic nailer with 2 3/8 galvanized or similar is a lot faster sheathing. But did use the screw trick since I was working alone

[KB-iejr]

Why not use 4x10 osb sheething installed vertically instead of 4x8 horizontally? You'd end up with less gaps in the sheething, less thermal bridging without all the extra blocking, and you wouldn't be left with that 2' section at the top. Only downside is that each sheet is 25% heavier and a solo install could be rough, but I assume that's what those 2 little helpers runnin around there were for, right?

[joeclark]

Okay Seth I hate to say it brother but you did that wrong that second row you should have started at the other end and with the 6 ft so that way you split your joints all your joints don't run together they're not supposed to that weakens the wall

[mutable.substance]

This is exactly what I was looking for, thanks a lot Seth

[EmadSinno]

Very nice presentation. I did not see that you verified the diagonals. How did you guarantee that the building walls are square at the top corners.

[jeffreylonigro]

Wow, that would take forever! We sheath and wrap the wall on the deck. Plus, you can pull your diagonals, pop a few toenails and you can sheath without worrying about knocking out of square. Why do non-professionals make trade videos?

[stateofwander]

Wouldn't it be better to not alternate your blocking so there is a continuous support for panel edges?

[JmguyN]

What nails did you use to nail the OSB

[garyring]

Why was the bottom plate not pressure treated? I know your not on a cemeny foundation with wayer wicking up but its a good practice as water is an issue at theat point of the structure

[Phuong_Nguyen_]

What would happen if I go crazy with the nail gun a do 4” spacing between nails?

[Himothy]

How many sheets did you need in total ?
