Metal bridging or cross bracing can be insulated simply by butting the batts to each side of the cross brace. Wood bridging or cross bracing of ceiling or floor joists is insulated by splitting a batt diagonally at the brace angle and packing one half into the lower opening and the other half into the upper opening. (See Figure 6.) Another method is to butt the insulation to the bridging,then fill the bridging space with scrap or loose insulation. There should not be any uninsulated gaps either above or below the brace.
