Special conditions prevail in catering kitchens. Humidity, temperature fluctuations and intensive cleaning are part of everyday life. At the same time, strict hygiene regulations must be adhered to in order to ensure food safety. Walls and surfaces in particular are subjected to heavy daily use – they must be resistant and easy to clean.

When planning or renovating a catering kitchen, increasing attention is therefore being paid to materials that have been specially developed for hygienically sensitive areas. Modern solutions in hygienic construction ensure that kitchen spaces remain permanently clean, robust and low-maintenance. The choice of the right wall materials is a key factor in this.

Hygienic requirements in commercial kitchens

Commercial kitchens and production kitchens are subject to clear hygiene requirements. Cleaning and disinfection are often carried out several times a day, sometimes with aggressive cleaning agents. At the same time, cooking processes, cooling and food processing create high humidity and large temperature differences.

In such environments, surfaces must not only remain stable, but also be designed in such a way that dirt or microorganisms cannot adhere to them. Smooth, easy-to-clean wall surfaces are therefore a crucial element in hygienic construction for restaurants.

In addition to daily cleaning, the building structure also plays a role. Walls must be able to withstand impact loads from transport trolleys or equipment without being damaged. This is because small cracks or damaged surfaces can pose long-term hygiene risks.

Typical weak points of classic wall materials

Classic tile solutions can still be found in many older catering kitchens. Although these fulfill basic requirements, they do have some disadvantages. The joints between the tiles in particular can become a hygiene problem. Dirt, grease or moisture can accumulate there over time.

Even coated walls or simple plastic surfaces often show signs of wear in intensive kitchen use. Scratches, flaking or damaged coatings make cleaning more difficult and can lead to hygienic weaknesses in the long term.

Particularly in areas such as cold rooms, preparation kitchens or production zones, materials that do not require many joints and remain durable are therefore in demand.

GRP walls as a hygienic solution

Surfaces made of glass fiber reinforced plastic (GRP) are a modern alternative to classic wall solutions. This material is used especially for hygienically sensitive areas and offers a particularly smooth, robust surface.

GRP walls are resistant to moisture, cleaning agents and mechanical stress. Thanks to their seamless design, they can be cleaned quickly and thoroughly, which means that hygiene standards can be reliably maintained. At the same time, they retain their stability and shape even with intensive use.

Particularly in catering kitchens, production kitchens or food processing areas, such materials can help to reduce maintenance work and create safe working conditions in the long term.

Areas of application in gastronomy construction

Hygienic wall solutions made of GRP are now used in many areas of modern catering buildings. They are used particularly frequently in cold rooms and cold storage cells, as low temperatures and high humidity prevail here.

Such wall solutions also offer clear advantages in preparation kitchens, production kitchens or food processing areas. The surfaces remain hygienic, are easy to clean and at the same time robust against daily wear and tear.

As a specialist in hygienic construction, FoodTec Buildings develops solutions for precisely these requirements. These include hygienic wall cladding, frame protection systems, hygienic doors and the expansion of cold rooms and production areas for restaurants and food businesses.
