Exterior wall sheathing?
Exterior wall sheathing?
(OP)
I have a new home being built and the builder has used both plywood and GP Densglass Silver in other areas. Why a combination of both? Is one better then the other?

Residential (in my neighborhood) is typically "cook book" type construction until you get into a custom designed home or a large home (greater than 5000 sq. ft.). So your contractor is probably following what is allowed by the residential code.

I agree with you with one exception. OSB (which is not to be confused with wafer-board) has great strength values. In fact, it has a higher specific gravity than most plywood therefore giving it a better nailing capacity.

I've read that it is good for moisture resistance, but like most of you stated regarding lateral loads, does it invite more shifting in the house, i.e. drywall cracking etc?
I've posted some pictures of my home and some other houses being built where they are using all Densglass.

The home is being built in Brantford, Ontario. I will follow-up with the local Municipality to try and find out if they are following local codes.
Do inspectors not come and check this type of stuff to make sure builders are following codes?

"In response to your enquiry we wish to advise the following:
Your query is two-fold; Densglass is an approved sheathing product having been evaluated by CCMC. However, the sheathing is not required in this application at Empire Communities.
Allow me to explain;
1. The sheathing required for wind or lateral bracing is achieved by the installation of gypsum board (drywall) on the interior of walls,
2. The cladding products used by Empire (brick veneer or vinyl siding) are attached directly to framing members without need for backing,
3. Empire's use of sheathing is considered an extra by their construction standard,
4. Further, the OBC does not give nailing patterns or loading criteria for sheathing. Where sheathing is required the OBC stipulates the minimum thickness of sheathing required and provides that sheathing is attached directly to framing.
We can advise that homes constructed by Empire Communities are built to the requirements of the OBC. Your concern for the "lack of bracing" will be addressed when interior finishing takes place."

Does your code accept drywall as such?
