Envision Building Products added 20-foot-long square-edge boards and 16- and 20-foot grooved-edge boards (to meet demand from deck builders who prefer to use hidden fasteners) to its Ridge Premium collection. The boards feature a high-density cap, which the manufacturer says is bonded to the core with heat and pressure to squeeze out air pockets and create a deeply grained surface. The boards are available in black walnut, gunstock, and vintage oak colors, with companion skirting available in all three colors as well. envisiondecking.com
