Does anyone have an appreciable history with installation of horizontal vinyl siding over furring strips, attached through several inches of rigid foam to studs?
I am referring to a general wall assembly with several inches of rigid foam over studs, followed by 1-by or ripped 3/4″ ply furring strips attached with headlok screws into studs, say on 16 in. centers–so that there are voids, or vented, areas between strips. How does the siding installation hold up if installed over such strips? Is it good to make the strips wider than, say, 4 inches so the vented areas are less and support for the vinyl is more? Certainteed vinyl siding installation instructions seem to be against this vented approach, but at the same time their website points to a technical bulletin from Fastenmaster that certainly supports the furring strip approach-so they are confusing.
