Interlocking surface mount panels employ a stock plank material designed to interlock along two edges. Mounted horizontally or vertically against the outer face of the framing, it is usually employed in long continuous strips, either the full available height or length of the structure or at least in wide strips with an end-to-end interface or cover strip, usually meeting over a frame member. Concealed attachment can be performed using angle strips attached to the inner profile slots. A special locking angle clip may be employed which hooks along one inner profile flange and clamps in place as the screw are tightened on the panels. This usually employs screw attachment with panels that have sufficient thickness to accommodate self-embedding screws. Front attachment is done using through-bolts to the outer panel faces. Vertical plank systems may employ a horizontal middle brace of 50mm 1x1 profile placed at a 1200mm on-center height between Primary and Secondary vertical frame members for improved rigidity. In some cases interlocking wall panels or structural panels may feature a recesses to conceal through-bolt mounting or special segment which snap lock to conceal screw mounting strips. Foam tape or standard profile weather strips along the front surface or profiles can be used to provide a weather-tight seal and cushion for the paneling.

Many plank materials may be employed. Typical materials would be;

Dovetail wood planking:

Corrugated Alloy or Plastic Composite planking:

Fiber-Cement planking:

Insulated foam core alloy SIP planking: alloy planking typically features additional flashing elements that can be combined with the basic planks for a finished look and are used for cover strips over Primary frame corners and roof fascia.

Extruded Clay planking:

[Study needed for angle-clip profile to see if off-the-shelf forms are available.]
