House Sheathing Material
Posted on 3/14/15 at 2:26 pm

Seems there are two main types of sheathing around this area on new construction homes, OSB and insulated sheathing panels. It seems as if the house would be better insulated with the insulated panels but maybe not built as solid. Anyone have experience with these two or anything else out there?

Are you talking about SIPs? If so, it's more than just sheathing.

The whole house is designed specifically for SIPs and the panels are made in a factory (there used to be one in Abbeville and still may be) then it's put together like legos on site with a crane and a few guys.

SIPs are solid. In fact, they have a higher wind rating than stick built IIRC. Been a few years since I looked into it.
I went to the factory in Abbeville and spoke to them and checked out the manufacturing process. It's interesting to say the least.

No 1/2 in Styrofoam is what I see.

Oh...I had no idea anyone still did that. I know it was common practice to do it pre hurricanes but they changed the codes. OSB the house and spray foam the walls. Best of both worlds.

Yep some builders up here put osb in the corners for strength and then do the rest in styrofoam.

Yeah, it's been a while since I seen this practice. I remember when sheet goods was sky high in price, some builders would wrap the corners in osb and the rest in either blackboard or a styrofoam. Codes axed the styrofoam I believe as I don't think it had a structural rating, but, I can't remember. We wrap entirely in osb in a residential build...fire rated if called for near set backs.

Check out the zip system by Huber. It's a great product I have sold a lot here in Alabama.

We put 1/2" plywood and 1/2" styrofoam on the corners. Rest of the house gets 1" styrofoam board. Taped joints. Course that's if your veneer is brick.
If it's stucco we sheath the entire house with 5/8" plywood and tyvec house wrap.

Reviving an old thread but that must be pretty costly to do. Seems about 70% of builders in the Monroe area do OSB in corners and 1/2 inch styrofoam everywhere else. They say it provides better insulation and is actually more expensive than all OSB.

Yes it's more expensive to do, but we build custom high end homes. This cost difference of plywood vs osb in those types of homes is negligible when considering the overall cost of the home.
Osb is cheap and its used because it's cheap. It's not used because it's a quality product.
