Choosing a hygienic wall and ceiling covering: the importance of the joints


The technical specifications of the joints are just as important as those of the wall covering for the renovation of a workspace!Porosity, number, resistance to repeated disinfection, smoothness, etc. are a few examples of areas of attention to bring walls and ceilings in line with a demanding sanitary environment.

When choosing the optimum covering, its hygienic characteristics are essential. In this context, the importance of the joint’s properties are sometimes forgotten. However, they also have to have several essential characteristics in order to comply with the highest standards.


The joint’s porosity , which affects hygiene

It is advisable to opt for watertight, non-porous joints that are easily washable. This is why installing traditional glazed tiles is not allowed in an aseptic environment. Nevertheless, glazed tiles are still found in the catering industry, production and processing premises, industrial sites, etc.

Of course, tiles meet certain requirements of the HACCP (Hazard Analysis & Critical Control Points) regulations. They are easy to clean, watertight, rot-proof and non-toxic while having a smooth surface.

However, their main weakness is the presence of numerous joints between the tiles. Their rough and porous nature increases the adhesion and absorption of stains, grease, scale deposit and dust. Even if the walls are thoroughly disinfected and maintained on a daily basis, they gradually become dirty and are affected by mould. This is compounded by environments with high humidity levels!

Resistance to repeated and aggressive cleansing

As is well known, disinfecting a workspace is very time-consuming. Rinsing with water does not suffice; thorough cleaning is required. It is advisable to opt for resistant joints that withstand repeated cleansing with aggressive chemicals and sometimes abrasive sponges. This is particularly not the case for tile joints.

Reducing the number of joints

Choosing a covering with a  larger height and width, and perhaps adaptable to your needs, makes it possible to reduce the number of joints. This has an impact on the installation time and possibly on the downtime, which can be shortened. Moreover, less joints mean shorter cleaning times. This makes it possible to significantly cut the costs of hiring a specialised cleaning company.

A smooth surface

A smoother work surface prevents bacteria from adhering to it, which in turn facilitates disinfection. It is also important to ensure that the wall or ceiling coverings chosen fit together perfectly, either via a male and female joint system, or via flush joints made with a specific type of putty. Regardless of the type of joint used, cleansing will be easier if the surface remains smooth.

As far as PVC panelling is concerned, most of the standard joints on the market do not interlock easily. Gaps and leaks are frequently seen, which let in germs and bacteria.

For optimum compliance

As with the wall and ceiling covering, an informed choice of joints should be made. To ensure that the highest sanitary standards are met, it is advisable to opt for suitable materials designed specifically for demanding work environments, such as watertight, non-porous joints that are easily washable, rot-proof, non-combustible and light-coloured (to facilitate visual inspection).Washable smooth panels for the food industry are an example.

To bring your workspaces into compliance, we advise you to opt for a wall or ceiling covering tailored to your needs.
