LINER PANEL L-21

LINER PANEL L-21 (Non Standard)

AVAILABLE IN VERTICAL PROFILE

The L-21 series panel is a high-performance liner panel, 2 feet [610 mm] wide 1 1/2” [38 mm] deep, with a flat room-side surface that can be specified plain or acoustically perforated. It is a concealed fastener system with an interlocking side joint. It provides improved structural capacity as well as an increase in air and water infiltration performance. The L-21 panel is designed to be used as the liner side of an exterior wall assembly. The liner performs in conjunction with the subgirt and exterior panel to support the applied design loads.

Note: Liners require planking on roofs to support construction loads. Liner panels cannot be used as single skin exterior walls or roofs.
