The ceiling membrane is of vital importance to the integrity and performance of any cleanroom. The concept of the ceiling can vary from simple suspended lay-in grid types to sophisticated 'walk-on' construction plenums.

The Thrislington 'Walk on Ceiling' is a product that offers amazing options in creating custom and system-build solutions to the most complicated of enclosures for the demanding environments of the cleanroom user.

A maintenance engineer can walk on top of the ceiling to gain access to services and components without the need to engage elaborate equipment normally associated with more basic ceiling installations and the servicing thereof.

Panels are constructed to standard width of 947 mm / 1197 mm with a thickness of 50 mm / 60 mm / 80 mm and the ceiling system is supported either on the partitions or by a lattice truss system to create spans not normally associated with partitions and ceiling enclosures. The steelwork is also designed, manufactured, and installed by Thrislington. Structural mezzanine floor applications are also available where high load specifications are required.

Subject to specification, each plank will hold a superimposed load of  27 kg/m2 together with a point load of 150 kilos.

Whilst the basic system is supported on the partitions, Thrislington can also provide plank & tile alternatives designed to be suspended from a concrete or steelwork structure by a unique hanging system. In these situations the ceiling can be installed independently from the partitioning, giving faster relocatable advantages for subsequent layout changes.

A walkable ceiling refers to a ceiling system that is designed to be used as a working surface, allowing people to walk on it for maintenance or other purposes. Some potential benefits of using a walkable ceiling include:

There are several potential benefits of Walkable/Non-Walkable Ceilings:

• Accessibility: A walkable ceiling provides easy access to the ceiling space for maintenance, repairs, or other tasks.
• Flexibility: A walkable ceiling can be reconfigured or modified as needed to meet changing needs or requirements.
• Improved safety: A walkable ceiling can reduce the need for scaffolding or other temporary structures, improving safety for workers.
• Energy efficiency: Some walkable ceiling systems are designed with energy-efficient features, such as insulation and airtight seals, which can help to reduce energy costs.
• Durability: Walkable ceiling systems are typically designed to be durable and able to withstand the weight of people walking on them.
• Customization: Walkable ceiling systems can be customized to meet specific size, layout, and performance requirements.

On the other hand, non-walkable ceilings are not designed to be used as a working surface, and are not intended to be walked on. They are typically used for aesthetic or functional purposes, such as to improve the acoustic environment or to hide mechanical systems. Non-walkable ceilings may be lighter and less expensive than walkable ceilings, but they do not offer the same level of accessibility or flexibility.
