Boise Cascade has expanded markets for its AJS 24 FMJ Fire Membrane I-Joists. The joists come ready for installation in unfinished residential basements and are designed without specified top and bottom orientation to ensure correct framing. Boise Cascade says the joists are noncorrosive to fasteners and are lighter than equivalent 2×10 and 2×12 floor systems, with a wider nailing surface. The joists include a foil-faced insulation board and meet stringent durability and ICC-ES fire protection standards. Pricing varies by distribution market. bc.com
