Description

The Nichiha EX Series wall cladding system consists of pre-finished, cement-bonded, fibrous wood particle panels in numerous profiles/finishes, the panel dimensions are 3,030 mm by 455 mm with a nominal thickness of 16 mm.

Panels are pre-finished using a durable multi-layer paint process and a Nichiguard stain resistant coating. Panels are tongue and groove profiled along longest edges and fit together to form a waterproof joint. Joints at the ends of the panels are aligned for each panel course and are finished with sealant.

The panels are secured with proprietary components and are installed over a flexible wall underlay or rigid air barrier.

The Nichiha EX Series wall cladding system may be used as an external wall cladding and as an internal wall lining for all buildings within the scope of limitations detailed in this product certificate.
