Potential problems regarding the use of ZIP System's new R-sheathing?
Does anyone see any potential problems using ZIP System's new R-Sheathing? The product comes in either 1/2" or 1" polyiso on the back of the sheathing between the sheathing and the studs. http://www.zipsystem.com/zip-system/rsheat.aspx.
Once again I am trying to figure out less costly ways to combat thermal bridging, create an air seal, and provide a rainscreen. I would be using the product with no interior vapor barrier therefore reducing the possibility for trapping moisture in the wall cavity.
However, is there the chance you would be creating a place for condensation to build between the foam and the studs? If I were to use the product I would use a product such as Rainslickr as a rainscreen for the ease and speed of installation.
