I'm building a new home and wanted to be on top of things that may become major issues later on. They just did most of the framing and there are some 2x4s which are visibly bowed as well as floor joists which are bowed as well.
Upstairs I could see light coming through some of the walls that are coming together which was kind of surprising. There were a couple of small gaps between the walls which had light shining through.
I didn't realize they no longer use OSB on the exterior walls and it looks to be some structural insulated sheathing which looks and feels very cheap. I'm not even sure how this will hold the siding on to be honest.
If something were to hit the house it would seem like it would be easy to punch a hole right through this stuff.
Here's the sheathing product they used.
Are any of you familiar with this? I'd like to get your thoughts both on the sheathing, the holes I have found punched through in various parts of the exterior walls and what problems I could be facing with bowed wall studs and floor joists.
I'm not very savvy when it comes to this stuff which is why I come here to ask the experts. I really want to know the right questions to ask my project manager for the house or demand things before I sign off on anything. Thanks!
