B. Steel framed buildings (including reinforced concrete core with LGMF exterior walls) of more than three floors (or 45 feet) require a compression joint every 25 feet at a floor line. B. Panel Cutting 1. Always cut fiber cement panels outside or in a well ventilated area. Do not cut the products in an enclosed area. 2. Always wear safety glasses and NIOSH/OSHA approved respirator whenever cutting, drilling, sawing, sanding or abrading the products. Refer to manufacturer SDS for more information. 3. Use a dust-reducing circular saw with a diamond-tipped or carbide-tipped blade. a. Recommended circular saw: Makita 7-1/4” Circular Saw with Dust Collector (#5057KB). b. Recommended blade: Tenryu Board-Pro Plus PCD Blade (#BP-18505). c. Shears (electric or pneumatic) or jig saw can be used for complicated cuttings, such as service openings, curves, radii and scrollwork. 4. Silica Dust Warning: Fiber cement products may contain some amounts of crystalline silica, a naturally occurring, potentially hazardous mineral when airborne in dust form. Consult product SDS or visit 3.4 CLEANING AND MAINTENANCE A. Review manufacturer guidelines for detailed care instructions.
