Zealot /ˈzelət/ - a person who is fanatical and uncompromising in pursuit of their ideals.
Z-Girt /zee-girt/ - an antiquated way of putting cladding onto a building that would often severely hinder the effective R-value of an exterior wall.
You know Knight Wall from their award-winning CI, HCI and MFI systems. In fact, you may have seen them on some recent projects, including one of the first certified Passive House projects in Pittsburgh. That reputation continues as they the launch a new product that should make increasing the effective R-value of your wall assembly even easier!
Knight Wall’s ThermaZee employs a specially designed, hollow, thermal isolation strip complimenting other performance enhancements at the web of the girt. The webs unique punch pattern has a substantial reduction in metal penetrating the insulation – about 75% – which decreases heat-flow through the girt. With up to 93% exterior insulation effectiveness, the Knight Wall ThermaZee easily meets the requirements of the IECC in all climate zones (maximum U-Value 0.064) with only 3.5” of exterior mineral wool insulation without the need for interior batt insulation.
Like traditional Z-furring, the ThermaZee can be installed either vertically or horizontally, attached to a variety of substrates such as steel studs, wood studs, CMU and concrete. Also, like traditional furring, a variety of claddings can be attached directly or with secondary rails. These include fiber cement, metal panels, HPL panels or aluminum composite material (ACM), among others.
It’s got thermal performance. It’s got ample drainage. What more could you want????
