Knight Wall Systems now offers its PanelRail cladding attachment rails for use with systems other than Knight’s proprietary rainscreen attachment systems. PanelRails can be employed as a second layer of rails to help accommodate different panel layouts and sizes to add depth. They also can be used in assemblies not requiring exterior insulation, where rails are installed directly over the substrate (steel studs with gypsum sheathing, wood studs with sheathing, CMU, etc.), enabling increased air flow behind the cladding while allowing water to drain efficiently. Rails may be attached to substrate or other rails in a vertical or horizontal orientation with a standard depth of 3/4 inch in face dimensions of 2, 3, 4 or 5 inches. The rails are available in 18- and 16-gauge corrosive-resistant Zn-Al-Mg ZM40 coating and can be specified in standard silver or a coil-coated black PVDF finish.
