The Sterling Structural CLTower Shaft Wall Kit-of-Parts is a prefabricated mass timber solution designed to streamline shaft wall construction. Built with 100 percent domestically sourced and produced cross-laminated timber, the shaft walls exceed one-hour and two-hour fire-rating requirements and install in any weather in a matter of hours, not weeks, the company says.
