The most typical installation for this application is a standard over the purlins/girts placement. Commonly the insulation is installed from ridge to vent followed by the metal panels. Walls are insulated by stapling the insulation over the girts from vent to sil plate with the wall panels attached over top. Other Low-E products are available for under slab or stud out interior insulation.
