Tyvek Homewrap or fully adhered alternatives
Tyvek Homewrap – 16 cents/sq.ft.
Henry Blueskin VP100 – 1.08 $/sq.ft.
Siga Majvest – 1.6 $/sq.ft.
If I go the Tyvek route I’d be taping the wall sheathing first as part of my air barrier. If I use the Henry or Siga products, which are fully adhered, I don’t need to pre-tape the sheathing, right? They would provide similar air barrier capabilities?
Even with the taping, the Henry & Siga products will still end up multiple times more expensive. What is the compelling case for going with one of those?
