    This membrane is fantastic! It is more durable, and has a much higher perm rating than the generic brand, and the price per square foot is great too. I used to have problems with house wraps deteriorating, and walls rotting. Fortunately, I found this stuff, and have been hooked ever since.

    Majvest is a durable rain proof building membrane that breathes. Don’t buy Tyvek and related products. They will deteriorate and you won’t know there is a problem for years. Majvest is the best. You’ll be happy you protected your home or building with Majvest!
