Using Fluid Applied Tyvek as an air barrier inside the home
Q4xdfu8ocj
| Posted in Green Products and Materials on
I have been doing a lot of research lately on air barriers and have read up a lot on EcoSeal and EnergyComplete. Both products seem superior to simply applying caulking to joints and cracks. My question is since both Ecoseal and Fluid Applied Tyvek are vapor permeable and air barriers, what would the downside be in applying the Tyvek on the interior of the house where you would normally apply EcoSeal or EnergyComplete?

Don't have much experience with the products but it doesn't keep me from having an opinion. 1: tyvek product is also a weather barrier. If you buy it and only put it on the inside aren't you wasting money? 2: is the Owens Corning product better for sealing interior joints than the other? Probably a better air seal because they don't have to make it as weather resistant. Interesting thought but I would tend to use the product in an application it was designed for. Although I am not opposed to using products in ways that no one intended. One of the fun things about being a contractor.
Joe, why, is fluid applied Tyvek less expensive?
Joe,
Carl's comments make sense. If I were you, I'd direct my questions to the technical help people at DuPont Tyvek.
We all know I think little of standard OSB. So now your idea has me thinking, you could put Zip up inside out and use the standard spray caulk, and then put your liquid barrier on properly with taped seams. Just may be bullet proof overkill sheathing!
Try that experiment, I like it. If you spray the inside instead just spray the caulk first on all the seams and joints, because you would never tape all that in one lifetime.
