Hardwall Cleanrooms

Hardwall cleanrooms provide outstanding performance and aesthetic appeal. Their rigid-wall construction allows for higher internal air pressures than those in softwall cleanrooms, meaning better performance. Wall panels come in many materials. Windows and other accessories can be added to customize your hardwall cleanroom.
