** NOTE TO SPECIFIER ** 6 Inch Wall Insulation: We are routinely asked how to insulate the walls of a steel building with 6 inches (152 mm) (R19) blanket insulation. It can be difficult to compress that much insulation between the panels and girts and inconsistent compression can be quite visible. Many contractors have found a solution to be the removal of a small amount of the fiberglass at each girt line. Cut the insulation with a utility knife and remove about 1-1/2 inches (38 mm) of fiberglass prior to sheeting. This adds only a small amount of time and alleviates the complication.
