2-layer cleanroom wall system

Bi-Panel1

The 2-layer wall system is an innovative cleanroom solution designed to offer exceptional flexibility, efficiency, and easy modification options. This advanced system enables parallel construction, where one side of the wall allows the cleanroom to remain fully functional while construction work can take place on the other side.

Main Features and Benefits

Increased Flexibility and Accessibility

The 2-layer cleanroom wall system consists of a substructure with panels attached on both sides. This unique design allows for quick and easy assembly and disassembly of the panels, greatly simplifying modifications. Unlike traditional monoblock systems, where service lines are embedded within the elements, the Bi-Panel partition wall system provides an installation cavity between the panels. This cavity can be adjusted to different depths as needed to accommodate ducts, cables, and other media, ensuring adaptability to various project requirements.

The suspended ceiling, which complements the 2-layer partition wall system, supports a uniformly distributed load (UDL) of 2.5 kN/m², with hangers arranged in a grid of 2.4 m x 1.2 m. This large hanger grid allows for the installation of mechanical and electrical (M&E) components above the ceiling while minimizing collisions. The ceiling features grid profiles spaced 1.2 m apart. Between the grid profiles, cleanroom ceiling panels are installed from above. For walkability, galvanized steel cassettes are also inserted from above. The panels, lighting, and other ceiling fixtures are interchangeable, providing a quick and flexible solution. Additionally, cables can be concealed within the grid and panels, resulting in a clean and safe walking surface above the ceiling.

Optimized Construction Process

The 2-layer cleanroom wall system allows for the rapid installation of other trades, so electrical and mechanical services can be installed almost simultaneously with the construction of the partition wall. For example, electricians can install cable trays, sub-distributions, and other components within the service cavity before the panels are fully installed. This shortens the overall project duration and avoids unnecessary waiting times.

Efficient Modification and Maintenance

One of the outstanding advantages of the Dagard 2-layer cleanroom wall system is its ease of modification. When a room needs to be upgraded or reconfigured, individual panels can be removed and replaced without significant effort. Media within the cavity are easily accessible by simply removing the panel, eliminating the complexity of accessing internal installations in traditional systems.

Furthermore, the 2-layer cleanroom wall system enables a "plug-and-play" approach for service lines. Sockets, lighting fixtures, and other components can be quickly disconnected, removed, and repositioned without extensive construction work, providing a cost-effective and sustainable solution for dynamic environments.

Off-site Manufacturing for Quality and Efficiency

All partition wall components are prefabricated at the Dagard manufacturing plant in Boussac, France, ensuring precise construction and high-quality surfaces. This prefabrication approach minimizes on-site waste, reduces disruptions during construction, and accelerates assembly. Pre-made openings for lighting units and connection boxes further enhance efficiency and enable seamless installation once the panels arrive on site.

Comparison with Monoblock Systems

While traditional monoblock systems require workshop modifications for each new integration within the panel, the Bi-Panel system allows for direct, on-site adjustments without extensive cuts or re-fabrication. For example, lighting fixtures can be easily repositioned within the ceiling layout, and ceiling outlets can be moved without waste or the need for new panel deliveries.

Conclusion

The Dagard 2-layer cleanroom wall system is a true game-changer in partition wall construction, offering unparalleled flexibility, rapid installation, and seamless media integration. Whether for new builds or renovations, this system provides a highly efficient and adaptable solution.
