Re: [GBlist] Housewrap compatibility with Tyvek(r)

[Scott Stolarczyk <sstolarczyk@robertsonsherwood.com>]

I have heard stories for builders that they have gone back to a project after
only a few years to find that the Tyvek/house wrap had actually disintegrated.
I am not sure if this is from adhesives, weathering, or a poor product.  You
may want to talk to some builders to find out their experience.
