Kerf Support System
Designed and specified to support ornate and shaped stone façade panels, where it is not possible to use FZP undercut fixings due to stone thickness.
The system is an optimal solution for large and flat facades using L-brackets, vertical rails and special designed horizontal kerf rails.
The horizontal Kerf rails are fixed into the vertical T & L profiles using tek screw or rivet connections. The kerf rail profile is suitable where the stone façade panel is supported using a groove in the upper and lower edge of the stone panel, this allows the stone panels to slot into the upper and lower rails.
The system comprises of two different kerf rails, the intermediate kerf rail and the upper/lower kerf rail. The upper/lower kerf rail is typically used at the base detail, window junctions and head details. The intermediate kerf rail is used in-between stone panels creating a horizontal joint.
The horizontal rails are designed to span 400-600mm between the vertical support structure.
