Our builder just reached out and let us know that zip board has gone through the roof (pun intended). He is recommending using a standard OSB + House wrap sheeting.

1.) Does anyone on here have any insight if it truly has gone up so much more vs standard OSB.

2.) Is there any major concern about going standard house wrap instead of zip board? He is saying it is much cheaper.

It's basically OSB with an air barrier on one side. They typically use Zip tape between the seams to keep it more airtight.

Are you doing spray foam or traditional batt insulation? It doing foam, you're getting your airtight air barrier that way and it doesn't make much of a difference.

I have always wanted to go with a ZIP exterior sheathing product in our builds, but could not justify the cost in the past. OSB has doubled, tripled...maybe even quadrupled in cost over the last year? I would assume ZIP products would've gone up as well?

Zip is currently running about $41/board compared to $34/board for standard 7/16 OSB.

Thanks for the replies! Sounds like it is up but not astronomically more. But over the entire house could amount to a big difference.

About $400/bundle more and then the builder usually charges more on install since they also have to tape and roll the seams. So it can definitely be thousands of dollars more for a house.

Thanks for the info! Really do appreciate it!

Which is dumb if you think about it because house wrap is much more work to install than just taping seams.

I don't disagree with you. The truth is that anything "out of the norm" typically ends up costing more. Low hanging fruit for up-charges.

I prefer zip as it is more idiot proof.

Exactly.

If the spec is zip sheathing, I would get zip sheathing. It's what I would do if I was building a house. It's not something that you'll ever be able to retrofit in the future.

Is OSB and Tyvek acceptable? Sure, but it's not interchangeable.

How is the contract structured?

I would agree on the zip vs. tyvek assertion. A better apples to apples option would be zip vs. osb with a fluid applied awb. Tyvek will never perform the same as a properly installed zip type sheathing.

We are now going with ZIP. Thanks for all of the feedback and responses! Prices are not as different as initially conveyed!
