Accoya wood from Accsys Technologies isn’t just any wood. The company calls it an “unrecognizable food source,” which is to say insects and fungi don’t know to feast on it. The wood undergoes a modification process called acetylation that fundamentally alters its cell structure by replacing one water-absorbing chemical group with acetyl, which won’t bond with water. (And acetyl is naturally present in wood, so Accoya includes nothing toxic.) The process makes the wood Class 1 durable and suitable for extreme outdoor conditions. It’s made of radiata pine sourced from FSC- and PEFC-certified forests and is Cradle to Cradle Gold–certified. Newer versions of Accoya come from alder wood, using the same acetylation technology.

Boral Stone Products has introduced Versetta Stone, a nonstructural, cement-based manufactured stone that requires no mortar, painting, or sealing. Made of 50 percent recycled content, it’s about a third the weight of full-thickness stone and comes in two styles and three colors, including Ledgestone Sterling (shown). The product’s fastening system uses 8-by-36-inch interlocking panels. For more information, call Boral Stone Products at 866-557-8663 or visit www.versettastone.com.
With storm season approaching, multifamily owners will want to ensure they have stormwater runoff under control at their properties. CalStar Products’ permeable pavers do the job while contributing to multiple LEED credits, according to the company. The ASTM C936–compliant pavers, designed to be installed with a permeable sub-base, measure 5 by 10 inches. Their large lugs provide open area to accommodate runoff, and the blocks help prevent flooding by draining at a rate of more than 800 inches per hour. Their binder uses 40 percent post-industrial recycled material, and their manufacturing process consumes 50 percent to 85 percent less energy than conventional processes. The pavers come in 11 colors and are ADA-compliant for slip resistance. For more information, call CalStar at 877-700-9501 or visit www.calstarproducts.com.
Weyerhaeuser has enhanced the fire resistance of its Trus Joist TJI joist line with Flak Jacket, a special coating that complies with 2012 International Residential Code fire-protection requirements. The product enables multifamily builders to construct fire-rated assemblies using a single layer of gypsum and no mineral wool. The joists don’t require special tools or training—builders can cut and drill the joists as usual and use standard hangers for quick installation. They come in multiple series and depths to meet various load-bearing requirements. For more information, call Weyerhaeuser at 888-453-8358 or visit www.woodbywy.com.
The Apex Ultrex Siding System, made from pultruded fiberglass, features factory-applied clips that hold it away from the building’s weather barrier to create a natural evaporation and drainage plane. The self-aligning, interlocking, 16-foot-long sections install securely, creating tight seams with no visible nail holes. They have an expected life of 50-plus years and come in 10 colors, two widths, and a smooth or wood-grain finish. For more information, call Apex Siding at 888-215-1092 or visit www.apexsiding.com.
Advanced Building Products’ Mortar Maze mortar deflection system breaks up mortar droppings within masonry cavity walls, allowing moisture to drain more effectively.
