DonTx Posted July 11, 2004 Report Share Posted July 11, 2004 Mike and anyone else in the Pac NW. In your part of the world, are house wraps put on between the inside of OSB or on the outside of OSB (or other sheathing)? Do you know anything about Pactiv Ultra House Wrap? Is it like Tyvek or is it a moisture barrier? Thanks, Donald Quote Link to comment Share on other sites More sharing options...
Jim Morrison Posted July 11, 2004 Report Share Posted July 11, 2004 Donald, Check it out for yourself here: http://www.pactiv.com/green-guard/. I've not seen it installed, but I will depart from my customary cynicism and say like the idea. I guess time will tell. Quote Link to comment Share on other sites More sharing options...
hausdok Posted July 12, 2004 Report Share Posted July 12, 2004 Hi, They don't use vapor barriers in walls on this side of the Cascades. Most sheathing here is plywood or OSB anyway, and these are, technically, moisture barriers anyway. Can't speak to what they do in Eastern Washington. They use either wrap or felt here - felt mostly. I've seen the Pactiv product used on a couple of new homes. It is like any other type of 'wrap' - it is designed to be an air barrier, not to keep out moisture. Because there have been so many problems with homes rotting, because water got past the wrap and became trapped against the sheathing,Pactiv designed their product to provide a slight gap which is presumably deep enough to allow drainage. I'm skeptical, but I'll give it a year or two to see how it compares to felt's ability to allow a wall to dry out. ONE TEAM - ONE FIGHT!!!
