Fast-R Insulation Hangers
Fast-R wall insulation hangers are 32-inch long galvanized steel strips with barbed arrows centrally located every eight inches. The strips are hung in the wall cavity between the girts and insulation and the insulation is then impaled onto the arrows where it will retain its shape and position within the cavity for the life of the system.
