Hardwall modular clean room walls are a superseded system, that meets cleanroom standards up to ISO 4 class. In addition, with a standard thickness of 50mm, the structure provides a composite, a class 1 fire reaction polyurethane core.

The vertical wall panels form a perfectly coplanar surface with an optimized pitch to achieve the required size, therefore the hardwall allows assembly even by non-specialized professionals.

Modular structure

Hardwall modular clean room wall kits are available in two different types. The standard kit provides a pre-painted iron sheet in RAL 9010 or AISI 304 with concealed quick-release coupling system. The pharma kit offers 2.5 mm thick plastic laminate surfaces, in white or white-green, with an internal metal stiffening frame and connection system with tongue and groove joint.

We provide a suspended ceiling with panels similar to vertical sections and a double suspended ceiling for ISO5 laminar flow classes and higher. The thickness of the ceiling is depending on span widths.
