This place is on the main drag into our town. It's been in this state for over three years. Husband mentions it every time we drive by. Yes, it's getting old.
Anyway, I wondered how long Tyvek wrap lasts when exposed to the Minnesota elements. So I checked with my friend, Google. From the DuPont (TM) website FAQs:
How long should Tyvek® WB be exposed before it is covered with siding? Tyvek® HomeWrap® and Tyvek® StuccoWrap®, Tyvek® DrainWrap™ and Tyvek® ThermaWrap™ should be covered within 120 days (4 months). Tyvek® CommercialWrap® should be covered within 270 days (9 months).
Husband calls this an "unintentional materials aging study".
