Description

KOROK® External Wall Systems incorporate KOROK® panels that are used to construct non-loadbearing, standard, fire and acoustically rated vertical straight external walls without penetrations.

The KOROK® panel forms the exterior cladding of the KOROK® EX1 and EX2 systems. The KOROK® EX3, EX4 and EX5 systems require protection with a suitable cladding system as specified in the technical literature for KOROK® External Wall Systems.

KOROK® panels are available in two panel profiles (KOROK® Gen 1 and KOROK® Gen 2 panel) and are made from lightweight aerated concrete encased in profiled galvanised sheet steel. For the KOROK® Gen 1 panel profile, paint-coated steel coil may also be used for one or both faces.
