Interlocking Plank

When installing the Interlocking Plank landscape, it is common practice to start at the top of the elevation, interlocking the top of one plank into the bottom of another. Centres are determined by the size of cassette, please contact the BENCHMARK Technical Department for details.

If this option is specified in Zinc or Corten, vertical top hats are required for ventilation. 

When installing the Interlocking Plank portrait, the orientation of the top hats and starting position will change, however, the same fixing method will apply. 


Minimum size for plank, 160mm x 150mm. Maximum size for plank, 3950mm x 290mm.



When a design demands colour and tone, BENCHMARK by Kingspan has a vast palette of choice. Aluminium can be coated in any RAL or BS colour, with coatings that can replicate more expensive metal options.
We have hundreds of options from metallic, standard, pearlised and textured.
