Cleanroom Ceiling

The Nicos Cleanroom System is a fully modular solution. Not only the wall partitions, but also the cleanroom ceiling comes in modules. It is designed to ensure maximum performance and flexibility.

Main Components:

• Structure:
  • A primary support framework consisting of tensors and threaded rods (8mm diameter) that suspend the entire ceiling system from the structural ceiling above‍
  • Aluminum Framework: T-type profile structure in either anodized or painted aluminum that forms the grid system
  • Can be installed with or without a plenum/veil‍
• The Finishes Full range of materials: HPL, UPVC, painted steel, painted aluminum, stainless steel(same as wall panels

• The Design
  • T-Grid Tiles: walkable or not walkable;‍
  • Full-Size Panels (Seamless Walkable): generally steel panels; 4’x10’ in size

Technical Details:

• Support system uses superior supports (10mm with two holes) and inferior supports (6mm with one hole)
• Rounded aluminum profiles with 60mm radius for external edges
• Fastening system includes M6x20 hexagonal flanged screws with serrated heads
• Raw aluminum undershell and perimeter profiles
• Spacers visible in the T-type aluminum structure

Design Options:

• Available as walkable or non-walkable surfaces
• Finish options include HPL, UPVC, painted steel, painted aluminum, or stainless steel (matching wall panel options)‍
• Insulation Layer: Internal insulation using polystyrene, high-density rock wool, aluminum honeycomb, or polyurethane

• Available in T-Grid tile configuration or full-size seamless walkable panels (typically steel, 4'x10' dimensions)

There are two main ceiling models available:

- Seamless Panels Ceiling

- T-Grid Ceiling

Both options can be upgraded to a walkable ceiling, capable of supporting a live load of 35 PSF across the entire ceiling area. This allows two operators to perform maintenance activities on the ceiling.

The T-Grid and Seamless Ceilings can be supported solely by vertical walls for spans of 12 feet or less. When the span is over 12 feet, the ceiling needs to be supported by the structure above.

Seamless Panels ceiling‍

This hermetic, walkable false ceiling system is designed for cleanroom environments, offering flexibility, ease of assembly, and robust performance.

By minimizing seams, the ceiling enhances airtightness, making it an ideal solution for potent product manufacturing areas or spaces where maintenance access from above is required.

Constructed with modular units, it consists of external skins made from the same material as our Cleanroom Wall System, with a steel frame supporting both live and dead loads, as well as hanging loads as indicated.

The ceiling panels are walkable, supported by a retractable load-bearing structure, and feature sound and thermal insulation. Resistant to humidity, the ceiling is capable of maintaining the specified cleanroom class conditions.

It can be installed before or after wall placement, adapting to various layouts and offering easy integration with plenum cap assemblies.

Filters, lights, and other accessories are accessible from the top of the ceiling. Pre-cut openings for filters, lights, and utilities are precision-machined at our facility using high-tech CNC pantographs.

The connection to the existing building's roof is made using a special extrusion combined with standard threaded rods and turnbuckle with double eyelet.

Self-Supporting Walkable Ceiling

We offer a fully Independent Self-Supporting Walkable Ceiling System, which eliminates the traditional requirement for roof suspension through an independent structural framework capable of spanning up to 25 feet without intermediate pillars. Unlike conventional cleanroom ceilings, this solution creates a true "box-in-box" environment. The self-supporting design provides superior stability, reduced vibration transmission, and complete isolation from the main building structure—making it ideal for sensitive applications or facilities where roof attachment is impractical. This approach significantly enhances flexibility for cleanroom positioning within existing structures while simplifying future reconfiguration or relocation.

Seismic can be achieved with a combination of additional parts (special plates, connectors, profiles) which are part of the system offered.

T-Grid ceiling

Whenever the driving factor in the cleanroom ceiling selection is flexibility, a T-Grid system is the ideal choice. Position of HEPA filters and light fixture can be decided up to the last moment and can even be swapped after installation.

The T-Grid ceiling is a hermetic false ceiling designed for cleanroom environments. It features a load-bearing T-Grid structure made of extruded aluminum profiles that support ceiling panels, lights, and filter units.

The structure of the T-Grid Ceiling is suspended by threaded rods with adjustable turnbuckles, fastened to overhead supports at approximately 4’ intervals. The system offers flexibility with two standard panel sizes, 24"x24" and 24"x48".

The ceiling panels are constructed as sandwich panels, featuring sound and thermal insulation, as well as resistance to humidity. They are made of galvanized steel with a smooth, polyester-coated surface in RAL 9010 or RAL 9003. The back of each panel is reinforced with 3/8” plasterboard, factory-glued for added durability.

‍

Designed for easy assembly, the T-Grid structure ensures airtightness where lay-in components like panels, light fixtures and air diffusers are sealed to the grid with sealant to prevent air leakage and resist fungal growth. Optional polyethylene gaskets applied to the grid are available upon request.

The T-Grid Ceiling can also be certified as walkable if paired with heavy duty walk-on tile.
