Insulation materials are sandwiched between the two skin layers and sealed from the exterior by the aluminum framework. There is a selection list of materials for insulation according different needs in modular cleanroom construction. High standard quality is compliance with cGMP rules for cleanroom cleaning. The Modular cleanroon wall system is flexible thus allowing easy installation and accepts changes to design in the field and can be reconfigured for use in other locations.
