Knight Wall Systems
ThermaZee is a rainscreen girt that reduces thermal bridging, with thermal performance values more than 90 percent effective, dramatically increasing the rainscreen wall assembly performance. It provides specifiers and designers the simplicity of what they already know—Z-furring—with code-compliant performance and reduced thermal bridging that rivals modern thermally isolated clip and rail systems. The product employs a specially designed, hollow, thermal isolation strip attached to its back leg. In addition to the thermal break provided by the strip, the web's unique punch pattern has a substantial reduction in metal penetrating the insulation. Additionally, the girt is reinforced with notched bends and stiffening lips around the punches for extra strength. For more information, visit knightwallsystems.com.

Code Changes Mandate Rainscreen
This year’s 2021 ICC and IBC made important changes to section 2510 Lathing and Furring for Stucco. Changes apply to stucco installed over wood-based sheathings in moist and marine climate zones. The mandate requires a drainage material minimum 3/16 inch (4 millimeters) in depth, applied to the exterior side of the water-resistive barrier. WaterWay Rainscreen & Ventilation Mats accommodate this directive by creating space for drainage and promoting circulation through convection. From Boston to San Francisco, the rainscreen’s are endorsed by numerous distinguished building enclosure specialists in North America. Many believe, “Rainscreens offer such amazing redundancy and are so forgiving every building envelope consultant should make it their number-one recommendation.”
