What's Included

Engineered To Be Better

  • Sound Deadening Walls STC 35 (better noise reduction than other brands - STC 35 glass upgrade available).
  • Fire rated to Class A+ 40 minute thermal barrier (nearly 3x better thermal resistance than other brands).
  • EXCLUSIVE: DiamondCoat Durable 8 Mil White vinyl wall finish (33-100% thicker than other brands).
  • Easily cleanable smooth wall finishes so particulate does not get trapped in a coarse surface
  • 10 foot high walls for a higher preferred ceiling height and deeper plenum area.
  • Steel Door and Jamb (Larger) 40"x84", The industry's best door features: Heavy duty 20 ga. door, 16 ga. jamb, Galvanized steel, Powder coated finish, larger for better access 40x84, Gasketed jamb for sound conditioning, ADA Lever lockset, and 3 heavy duty hinges.
  • Stronger 3" thick hardwall panels, not flimsy thin walls and not bulky thick walls. 3" thick walls offer the optimum thickness for strength and performance, without adding unnecessary core thickness costs.
  • Non-progressive interchangeable component design. Easily change your configuration to move door, window or solid wall panels, and electrical without disturbing adjacent wall panels. All components are consistently sized to provide maximum flexibility; that's something most of our rivals can't say.
  • Roof Load Design includes beams 8'o.c., for a 20 PSF maintenance load to support ductwork and filtration.
  • Build for Change. You don’t just purchase a clean room from us, you purchase a system. A system you can add to for a larger cleanroom, reconfigure, convert to multi levels, take down and move; the possibilities are endless.
  • Modular Walls

    Completely modular and interchangeable solid hardwall panels with all connecting hardware. Nominal 4' wide (or 2' as needed) x 3 inches thick, 10' high (for better ceiling heights and increased plenum space), All metal components are painted to match the walls.

    NOTE: Wall panels utilize a base track that anchors to your existing concrete floor.

  • Steel Door

    MaxDoor, Heavy Duty Steel Door 40"x84" w/ 1/4" tempered glass, galvanealed: 20ga Door w/16ga Jamb, TextureCoat™ Powder Coat Finish, TiteSeal™ Gasketed Jamb, ADA compliant commercial quality hinges and lever lockset. Hinge and swing as requested in design phase. Solid door w/o glass available on request.

    Comparison Tip: Watch out for cheap hollow core wood-type doors. These light-duty doors will not last and won't stop noise effectively.

  • Cleanroom Electrical Package

    Complete basic electrical package including 2'x4' LED light fixtures, outlets, switch, and breaker panel.

    Also includes post preparations, wall conduit, junction boxes, and cover plates.

    Not included: Ceiling conduit, or wiring.

  • Standard Plenum Design for HEPA Filters

    Standard 2 foot high plenum design. Design allows for Type 1) Single Pass air flow system. If temperature and humidity control are not required and the surrounding air quality is acceptable, a single pass design with transfer grilles placed low in the wall for exhaust to the outside can be used, and Type 2) Recirculation design allows easy control of temperature, humidity and room pressure, when designed with return air grilles and ductwork. For filtration use either FFU HEPA's or direct duct to HEPA system.

  • Steel Roof Deck with 20 PSF Maintenance Load
