I see you've chosen to dig your hole deeper. Now you're lying. I never said anything of the sort. Try to pay attention. You said that Tyvek is just a wind barrier. That's not true. It's also there to prevent water infiltration if any water gets past the siding. Is it essential for a she d? No, but that doesn't change what Tyvek is, what it does.
despite that the shed is not normally
Sure, we should believe you rather than the company that makes and specs the product. But you're OK with them saying that it helps block wind, that's not marketing hype and lies. Go figure.
They're exploiting peoples' fear of water damage with a vague
You're an idiot.
Water *flowing* around or under siding
Sure, we should believe you rather than the company that makes it. How about This Old House video, are they lying too? They show Tyvek being installed and how it shields against water getting in:
United State Gypsum lying too?:
"Water repellent barrier protection for exterior drywall systems DuPont(tm) Tyvek(R) StuccoWrap(R) has an engineered grooved surface that can help bet ter manage water when installed as a drainage plane. "
It would seem USG that makes exterior building products surely knows about what Tyvek is to be used for, how it works to protect their siding products.
How about the International Building Code:
"SECTION R703 EXTERIOR COVERING
R703.1 General. Exterior walls shall provide the building with a weather-resistant exterior wall envelope. The exterior wall envelope shall include flashing as descri bed in Section R703.8.
"R703.1.1 Water resistance. The exterior wall envelope shall be designed and constructed in a manner th at prevents the accumulation of water within the wall assembly by providing a water-resistant barrier behind the exterior veneer as required by Sectio n R703.2 and a means of draining to the exterior water that enters the asse mbly. "
No siding system is perfect. I guess the concept of not relying on just one thing is foreign to you. See the IRC code above.
And again, I never sais she should, idiot.
She can read up on Tyvek, read the building code I cited and what you just said about relying only on siding to keep out water and then she'll know for sure that you don't know what you're talking about.
But feel free to dig deeper.
