Interlock : In demand for the most demanding areas


The Interlock™ Industrial Ceiling provides a tough, maintenance-free and durable planking that is easy to clean. Complying with the UK and EU regulations, Interlock™ is not only waterproof but impervious to most of the chemicals found in commercial and industrial kitchens, food processing plants and the pharmaceutical/medical industries. This makes it ideal for areas requiring stringent cleaning and frequent hosing down.

The special twin-wall construction helps to reduce condensation and its particle-free properties avoids contamination to foodstuffs Interlock™ is lightweight enough to be used as part of a suspension system. There are a number of other practical fixing methods to suit both new construction or refurbishment.

Interlock™ can also be combined with either Caterclad® or Waterfield® wall lining systems to provide the ideal solution for the most demanding areas - that’s why Interlock™ is so often in demand.

General Information

Interlock™ ceiling planks are of a rigid twin wall construction with multiple cross-supports. The planks are extruded using non-recycled PVC to ensure not only a white plank but also a product of consistent quality and colour.
