What type of rigid foam is best for under siding?
We are removing the existing siding down to the diagonal board sheathing. We are making some necessary repairs at this area where windows have leaked, then covering with Grace Vyncor env-s self-adhering housewrap. This seamed to be a good choice to seal all the gaps between the boards. All penetrations are flashed to this level. Then we plan to install 1″ foam panels with seams taped, 7/16″ Zip panel strips for a rainscreen, then LP Smartside lap siding. We plan to use foil faced poly iso board. Is this a good choice?
