The HSC high quality suspended metal ceiling complies with the highest demands in terms of hygiene, maintenance and robustness while keeping its impeccable aesthtics and stability over time.

Halton’s range of so called passive ceiling is an ideal solution for rooms with strong requirements in terms of hygiene and maintenance, such as kitchens, diswashing areas or foodprocessing industry, but also hospitals or laboratories.

HSC ceilings comply with the highest hygiene requirements while offering unique architectural qualities. Its exclusive design is based on components that are all assembled together flush. The wide supporting profiles (“brandraster” or flat healds) enable in addition to increase the ceiling’s panels span and width, with no compromise on stability. The number of healds and pannels is reduced. Less components, all mounted flush means less junctions where dirt can builds-up. HSC ceilings are hence easier and faster to clean.

The supporting profiles are designed to allow only few clearly identified panels to be lifted up. As long as they are in place, the other pannels can’t be either removed or lifted up unintentionally. This greatly facilitates the cleaning operations, whatever their intensity.

The supporting profiles are designed to allow only few clearly identified panels to be lifted up. As long as they are in place, the other pannels can’t be either removed… or lifted up unintentionally during the cleaning operations, whatever their intensity.

Only few panels marked as such can be lifted up. Thanks to the Halton’s “Lift & Slide” feature, they can be easily lifted up and slided on the top of the ceiling, enbaling other panels to be removed the same way. It allows for a large and quick access to the ceiling void for maintenance, without tool and especially without taking up space in the kitchen.

HSC ceilings is equipped with the Halton Skyline light fittings, also integrated flush. In its Human Centric version, Halton Skyline enables creating a lighting cycle close to that of the daylight, to improve the occupants’ Wellbeing.

As an option, the ceilings’ panels can be also equipped with an encapsulated acoustic insulation that directly contributes to significantly reducing the sound pressure level. The panels then improve the working conditions in noisy spaces while keeping the hygiene at the highest level.

HSC ceilings allow for the integration of multiple services such as HVAC components, emergency signs, smoke detectors, speakers etc from factory directly or on site by third parties. They are therefore equally suitable to all projects’ spaces requiring a high quality suspended ceiling.

Hygiene certification

  • HSC ceiling’s components passed a wide variety of tests, carried out in the laboratories of the the Fraunhofer Institute IPA in Stuttgart.
  • Suitable to all type of spaces and requirements, from commercial kitchens to clean rooms.

Services integration

  •  Halton’s Laminar Flow Units (LFU) that contribute to better working conditions and better air quality.
  • Halton’s Extraction Box (KBO) with FC aerosol separators for isolated low duty cooking appliances in kitchens. Other extraction solutions available.
  • Halton Skyline (HCL) light fittings equally efficient as a culinary ligthing or as Human Centric lighting, or both.
  • The brandrasters (wide flat healds) can be used as cable trays.
  • Other services or preparation for site services integration on request.

Other main features

  • Constructed from stainless steel or aluminium, anodised or painted.
  • Low height ceiling with supporting of brandraster-type (wide flat healds) for the highest stability. No need of reinforcement profiles.
  • All components mounted flush.
  • Easy to clean. Quick access to the ceiling void for maintenance.
  • No traditional support profiles excepting for the connection to the walls. Optional wall connection profile of “cove” type.
  • Easy to clean. Quick access to the ceiling void for maintenance.
  • Earthquake-proof quick connectors.
  • Multiple customization possibilities on shapes and finishes.

Highest hygiene and design standard

Suitable for kitchens and foodprocessing up to cleanrooms

Halton HSCTogether with the metal ceilings’ design specification, the material used and its surface properties are of great importance in areas with strong hygiene requirements. HSC metal ceiling has been developed according to the directives and rules of the GMPs (Good Manufacturing Practices) and the recommendations of EHEDG foundation’s (European Hygienic Engineering and Design Group).

The HSC metal’s ceiling design and manufacturing provisions first greatly limit the build-up of contaminants on its surface. To reach that goal, all its components, including the wide flat supporting healds, are assembled metal-to-metal and in a flush way. The whole visible surface is flat, without any protruding connecting elements (such as T profiles, rivets or screws) which represent a risk of dirt build-up, difficult to remove during cleaning. By using wider panels of greater span, the proportion of joints is significantly lower compared to classic ceilings.

The metal used for HSC ceilings’ manufacturing, and its surface properties, are the second key point to match the strongest hygiene requirements. It should not only facilitate regular cleaning operations but also to not be itself a source of contaminants. The paint has been carefully selected to get a smooth and homogeneous surface with a high resistance, mechanical and chemical for an efficient and safe use of common cleaning and disinfectant agents. The paint itself should also not release particles or gas, neither favor the proliferation of fungi or bacteria.


Halton HSC ceiling underwent and passed a wide variety of tests, which were carried out in the laboratories of the Fraunhofer Institute IPA in Stuttgart as shown below. HACCP International certification is pending.

Till clean rooms

Designed to match the hygiene requirements of kitchens, dish washing areas or food processing industries, HSC ceiling is suitable to any other application with architectural or hygiene challenges, till clean rooms. In that case, the only difference is that the components’ junction have to be treated with a specific sealant.

Acoustic ceiling

Improved acoustic comfort and discussions’ intelligibility

Halton HSCIn areas with strong hygiene demands, the surfaces of the walls, floors and ceilings are usually very hard and smooth, in order to efficiently prevent contaminants settling on it and make them easier to remove during cleaning operations. The inconvenience is that it creates a very reflective space for the noise. Porous and open-pored materials and surfaces are indeed required to get a good acoustic comfort.

The HSC ceiling’s optional acoustic panels combine hygiene with efficient sound attenuation properties and directly contribute to a better acoustic comfort.


  • Significant improvement of the sound absorption by the ceiling and reduction of the reverberation time.
  • Improvement of speech intelligibility and acoustic quality of rooms Max use temperature of up to +100°C.
  • Sandwich construction for all parts to be easy to dismantle and clean.
  • Detergents resistant.
  • B1 class fire protection.
  • Option for consistent wall panels to increase the absorption surface.
  • No breeding ground for microorganisms.

How does it work?

  • The acoustic insulation is made of closed-cell, low-density polyethylene foam. It is specifically for humid environement or steam exposures.
  • The sound waves penetrate the insulation through the pannels perforated front. The acoustic energy then largely convert into heat.
  • The pannels’ back plate reflects what remains of the sound waves back into the foam, to further increases its absorption.
  • The higher the degree of absorption of the acoustic insulation, the higher the sound absorption.

When reaching HSC acoustic panel, the energy of the incident sound wave (4) is split into the following components: the reflected sound (5), the absorbed sound (6), the sound trabsmitted by conduction (7) and   the transmitted sound (8). The transmitted sound is reflected back to the acoustic insulation (9) thanks to the panel’s back plate.
