BALANCE 

BETWEEN HYGIENE, 

ACOUSTICS AND AESTHETICS 

Wherever healthcare facilities are built or modernised, they 

create a challenge for clients, architects and planners. Strict 

hygiene regulations must be observed. Comfortable acoustics 

should also aid a person’s well-being. The building must be 

functional and yet aesthetically attractive in order to please 

the eye. 

Optimal ceiling for every room 

With the interplay of hygiene, acoustics and aesthetics, the 

ceiling construction plays a central role. The selection of the 

optimum ceiling system depends on the use of the room. Whilst 

hygiene is of paramount importance in operating theatres and 

intensive care units, sound protection and room acoustics are 

particular demands for corridors and foyers. In patient rooms, 

the ceiling contributes both in optic and function in creating 

a feeling of well-being. In sanitary areas and kitchens, the 

ceiling also has to withstand high humidity. 

The Knauf AMF hygiene range 

In our Knauf AMF hygiene range, you will find the most 

suitable ceiling system for every application area in healthcare 

facilities. Choose from a wide range of high quality products 

that fulfil the most diverse range of requirements (from 

hygiene to fire protection). Use our decades of know-how and 

experience in the healthcare sector and build on the highest 

quality and product standards; from the grid structure to the

CLASSIFIED 

IN ACCORDANCE WITH THE 

HOSPITAL STANDARD NF S 90-351 

When it comes to air purification and control 

in healthcare facilities, you cannot avoid the 

French hospital standard NF S 90-351. It is to 

date the most important and strictest standard 

for healthcare facilities, which is currently being 

discussed in European regulations. The standard 

classifies different application areas into four risk 

zones. The selection of a suitable hygiene-tested 

ceiling system is also dictated by these zones. 

(see also p21 onward). 

The French standard NF S 90-351 classifies rooms of healthcare facilities into four risk zones: 

Zone A

SPOTLESS 

PREVENTS GERMS 

Our Knauf AMF ceiling systems with Hygena coating have additionally been tested 

(JIS Z 2801 or ISO 22196) for the following germs: 

Proteus mirabilis 

• Proteus mirabilis is a facultative, pathogenic bacterium, found in the colon of healthy individuals and does not necessarily 

cause diseases. Immunocompromised individuals may suffer from the following problems caused by this bacterium: urinary 

tract infections, infected wounds, pneumonia and sepsis. 

Pseudomonas aeruginosa 

• This bacterium is a widely spread soil and water based germ, found in sinks, showers and toilets etc. and is therefore 

regarded as a major hospital germ. As the germs exhibit multiple resistance to antibiotics, due to its metabolism and 

membrane structure, it is the most frequently occurring hospital germ, causing 10% of all hospital infections in Germany. 

Clostridium difficile 

• Clostridium difficile is a harmless intestinal bacterium in healthy people. However, if competing types of normal intestinal 

flora are disrupted by antibiotics, C. difficile can proliferate and produce toxins which can lead to life-threatening diarrhoea. 

Aspergillus niger 

• Is also called black mold due to its dark spores. Aspergillus niger is a major spoiler of food and destroys materials. Illnesses 

caused by Aspergillus niger include infections of the external auditory canal, pulmonary aspergillosis, abdominal inflammation, 

endocarditis, nail diseases and also skin infections, in addition to allergic reactions. 

Knauf AMF products with Hygiena coating display a clear antimicrobial effect. 

8

Candida albicans 

• Is a certain type of the fungus genus Candida and the most common cause of so-called Candidiasis (an infectious disease 

with Candida-fungi). Candida is a yeast which can particularly settle on mucous membranes in the genital area, mouththroat 

or intestine. C. albicans belongs to the facultative pathogens (only causing illness under certain conditions) and is a 

saprobiont, living in equilibrium with human immune defense and other microorganisms. 

Escherichia coli 

• Escherichia coli is an enterobacteria belonging to the important genus Escherichia and occurs in human and animal 

intestines. However, some serotypes have a pronounced intestinal pathogenicity (such as EHEC - enterohemorrhagic 

Escherichia coli) and cause 160 million cases of diarrhoea and 1 million deaths per year. 

Staphylococcus aureus 

• Staphylococcus aureus occurs almost everywhere in nature and approximately 25 to 30 % of the population carries it on 

their skin and in the upper respiratory tract. Usually it does not cause any symptoms of illness but for immunocompromised 

people it can lead to life-threating illnesses. It has become well-known in the form of MRSA, originally methicillin-resistant 

Staphylococcus aureus, meanwhile also called multi-resistant, as it shows resistance to other antibiotics. 

Enterococcus faecium 

• Enterococcus faecium is a bacterial species found in the intestine of humans and animals. The pathogenic strains cause 

nosocomial infections (i.e. hospital infections) in people with weakened immune systems. Due to the resistance of the 

pathogen, the diseases are very difficult to treat, making the vancomycin-resistant Enterococcus (faecium) (VRE) one of the 

most difficult to control germs of all.

CONVINCING 

IN ALL CLEAN ROOM 

CLASSES 

Cleanrooms are essential for medical research and the handling and sterile 

production of pharmaceuticals. They enable different parameters, such as 

particle number, germ number, temperature, humidity, and pressure to be 

exactly monitored and controlled. This ensures that the existing air and intake air 

has a high purity and fulfils all cleanliness criteria. This helps to protect patients 

and ensures the quality of medical products. 

Air purity classification 

The air purity classification according to DIN EN ISO 

14644-1 is the most well-known standard in the 

area of cleanroom technology. It states the maximum 

number of particles in the ambient air and divides the 

cleanrooms into classes from ISO 1 to ISO 9, with class 

1 being the highest specification for air purity. 

It should be noted that clean rooms with classes 1 to 

5 according to ISO 14644-1 require a high filter area 

and the use of ceiling elements is not always possible. 

Clean rooms with horizontal displacement flow form an 

exception to this. 

Testing method 

Highly sensitive measuring equipment can determine the number of particles 

present in the ambient air of cleanrooms. Determining the number of airborne 

particles enables the classification of materials. Cleanrooms are classified 

depending on the number of measured particles per cubic metre. The only 

particle groups to be considered are those with a cumulative frequency 

distribution between the critical particle sizes (lower limit) of 0.1 μm and 5 μm.

LOW MAINTENANCE AND 

EASY 

TO CLEAN 

General 

Knauf AMF ceiling tiles are available with many different surface finishes. The 

different finishes can be cleaned using different methods. Normally ceiling tiles 

do not need to be cleaned in most standard applications. However, it may be 

necessary to carry out cleaning in some situations. 

Methods 

The following cleaning methods cannot be used on all surfaces. Refer to the 

table “overview of cleaning methods” for suitability. 

(1) Dry cleaning 

For standard cleaning of dust, loose dirt and/or deposits, a normal vacuum 

cleaner fitted with a soft brush can be used. 

(2) Damp cleaning 

For more intensive cleaning, the surfaces can be damp cleaned. This should be 

carried out with a wrung-out soft cloth or sponge. After cleaning, the surfaces 

of the tile should be dried with a soft cloth. 

(3) Wet cleaning 

Wet cleaning should be carried out with lukewarm water (up to 40°C), using 

a sponge and mild cleaning agent (with a pH value between 7 and 9). It is important 

that the edges and the reverse side of the tile do not come into contact 

with moisture. After cleaning the surface should be dried with a soft cloth. 

14

(4) Pressure cleaning 

Pressure cleaning is only for ceilings with an exposed grid 

construction (system C, edge SK), carried out with the 

following restrictions: 

Water temperature: max. 40° 

Working pressure: max. 80 bar, with a flow rate of 

max. 500 l/h betragen 

Spray angle (nozzle): min. 30° 

Minimum distance: 1,0 m (nozzle – mineral fibre surface) 

Water should be prevented from penetrating the grid structure. 

After cleaning, the surface should be dried. 

Note: 

The mechanical stresses of cleaning (scrubbing) may lead to changes to the surface. Highly adhesive dirt (grease, 

oils, acids and bases) can be resistant to cleaning and can affect the surface permanently. It is recommended to test 

the proposed cleaning method on a sample piece or a non-visible part of the ceiling. Cleaning should also be carried 

out over a large area and not limited to individual tiles or small areas. 

Tile types 

Not all mineral tile surfaces are suitable for wet cleaning or high pressure cleaning. The appropriate cleaning 

methods are set out in the table below:

MONDENA ® / THERMATEX ® Kombimetal plain 1x weekly 

TOPIQ ® 1x weekly 

THERMATEX ® Thermaclean S 1x weekly 

THERMATEX ® Aquatec 1x weekly 

Cleaning agents 

Generally, surfaces should only be treated with water or using a mild cleaning agent (pH value between 7 and 9). 

It is recommended to test and assess the proposed cleaning method on a sample piece or non-visible part of the 

ceiling to rule out colour reactions with the cleaning agent as well as scrubbing effects. Abrasive cleaners are not 

suitable and may not be used. 

Note 

Increased humidity due to regular cleaning or climate conditions means that enhanced corrosion protection 

requirements with regard to the supporting grid and fixings may be necessary. When the suspended ceiling is 

subject to uplift pressure loading, further measures again may be necessary dependant on the installation.

RESISTANT EVEN WITH HIGH 

HUMIDITY 

Humidity 

Humidity has a significant influence on the stability and structure of a mineral 

ceiling and therefore its longevity. High levels of water vapour content can lead 

in many cases to a loss of dimensional stability and deformation. Air behaves 

similarly to a sponge and can, dependent on the temperature take in water in the 

form of vapour.

Example with 1 bar air pressure 

At 20° C the total absorption capacity of air is approximately 

14.7 g/kg. If instead, the actual water content was 8.7 g/kg 

(=absolute humidity), this would result in a relative humidity 

of 60 %. If this air were then cooled, the water content would 

not change, however the absorption capacity of the air 

reduces. As a consequence the relative humidity increases to 

an extent, until at approximately 12° C, saturation is reached, 

beyond which no more water vapour can be absorbed 

(dew point). By further cooling, the excess water vapour 

condenses and leads to water droplet formation. Air at 0° 

C, can in comparison only absorb a maximum of 3.7 g/kg of 

water until it reaches saturation. 

= 20° C x = 14.7 g/kg = 100 % 

= 20° C x = 8.7 g/kg = 60 % 

= 0° C x = 3.8 g/kg = 100 % 

If unsuitable materials are used in these critical areas with increased humidity, in 

many cases it can lead to adverse visual effects or even structural damage. 

THERMATEX ® Aquatec can also be used in areas with upto 100% relative humidity, 

without any problems.

WELL-BEING WITH 

A PLEASANT 

AMBIENCE 

AND OPTIMUM ACOUSTICS 

Individual ceiling systems for an 

optimum feel-good climate 

For people who work here and also for those who 

come and go, the room climate plays a major role. An 

optimum feel-good climate promotes concentration and 

performance. Using bespoke ceiling solutions, various 

parameters such as room acoustics, design and lighting 

can be optimised for individual requirements depending 

on application. 

In zone A of the French hospital standard NF S 90-351 

are rooms within healthcare facilities, which do not 

place particularly high hygiene requirements on the 

construction or activities. They are general areas such 

as foyers and corridors, offices and meeting rooms as 

well as administration areas – from the caretaker’s 

room to the post room. The probability of being infected 

by hospital germs, bacteria or fungi in one of these 

rooms is relatively low. 

Sound optimised havens and a feast for the eyes 

Our Knauf AMF ceiling systems offer you the best sound 

absorption values and give you the greatest possible 

freedom of design. They are particularly impressive 

in heavily frequented corridors and foyers, where 

they effectively absorb disturbing noises, voices and 

noise. Peace and comfort arise. The timelessly elegant 

designs with a wide variety of surfaces and colours also 

offer high aesthetic value. They contribute to a light and 

healthy, feel-good ambience.

Sanitary facilities 

Kitchen areas 

In patient rooms and consultation rooms, an endless stream 

of patients, doctors, therapists, nursing and cleaning staff 

are coming and going. It is in the nature of things that germs 

and bacteria will spread in these environments. The French 

hospital standard NF S 90-351 classifies these rooms with 

average hygienic relevance, along with sanitary facilities 

(patient bathrooms, visitor toilets etc.), rehabilitation rooms 

or kitchens and food storage rooms. 

HIGH PERFORMANCE FOR 

INCREASED 

DEMANDS 

solutions are required to meet the increased hygiene 

requirements and create a positive and comfortable 

room climate. In addition to sound-absorbing properties, 

optically effective design elements are also included. 

After all, the patient usually lies in bed and often stares 

at the ceiling. 

Water vapour and humidity 

In hospitals and nursing homes, the humidity level 

in rooms is a very important factor to consider. In 

principle, the relative air humidity should always be 

in a healthy, acceptable range (generally between 40 

and 60 percent), so that patients and staff feel equally 

well and comfortable. In addition, moisture is released 

by permanently cleaning the rooms, not to mention 

the development of humidity in sanitary facilities and 

kitchens. For this reason, Knauf AMF also provides 

ceiling systems (grid systems and ceiling tiles) in our 

hygiene range, which are resistant to high humidity in 

the long term. 

Healthy ceilings in patient rooms 

Patient rooms pose special requirements for ceiling 

systems. They should contribute to a healthy, comfortable 

room climate, where the patient feels content, which 

in turn promotes the recovery process. Here, ceiling

High hygienic relevance 

HIGHLY DEVELOPED FOR 

SENSITIVE 

AREAS 

Special products for intensive care and air showers 

Wherever serious (often life-threatening) diseases and 

injuries have to be treated, particularly strict hygienic 

measures must be taken. Intensive care units therefore 

differ massively from other hospital areas. They are highly 

functional and allow optimal patient care in a germ-free 

environment. As a rule, they can only be entered via air 

showers. Thus, the import of germs is prevented. 

In these sensitive areas, highly sophisticated special 

products from our hygiene range are used, which have 

been tested and verified as having a preventive effect 

against germs. 

Specific conditions and application areas require 

special attention. Every room in zone C, according to 

the French hospital standard NF S 90-351 is a sensitive 

area such as a recovery room, intensive care unit, 

rooms for “small” operative procedures, delivery rooms 

and baby rooms. 

The risk of already weak people or people in exceptional, 

physical conditions becoming infected with germs 

or infectious diseases is relatively high. The hygiene 

requirements for the construction of these zones and 

the measures taken within them are also accordingly 

high. 

Consultation rooms and laboratories 

The ceiling systems developed for zones of high 

hygienic relevance are also suitable for use in autopsy 

rooms, sterilisation areas, laboratories, examination 

and treatment rooms etc. In addition to hygiene, our 

solutions also include acoustic, design and economic 

factors.

Very high hygienic relevance 

Sterile order on the instrument table, calm, rhythmic breathing 

noises and full concentration during the surgical procedure: When 

operating, the highest hygienic standards must be observed. Our 

recommendation for the ceiling: the hygiene-tested high-end 

ceiling systems from Knauf AMF.

Very high hygienic relevance 

Operating theatres 

Operating theatres and departments within zone D are 

the top tier of hospital design according to the French 

hospital standard NF S 90-351 – the highest hygiene 

level. Primarily, germs and pathogens are prevented 

from entering the patient‘s open wound during the 

surgical procedure, but the protection of the operating 

team against infections is also of central importance. 

Sterile zones, anaesthesia rooms, scrubbing areas and 

air showers must also comply with the highest hygiene 

standards. 

Ceiling systems for the highest hygiene 

requirements 

Our Knauf AMF ceiling systems for operating theatres 

and departments are technical high-end products that 

meet the highest hygiene requirements. They have 

a preventive effect against germs and prevent the 

accumulation of pathogens, bacteria and fungi. Moreover, 

they are robust, disinfectant-resistant, low maintenance 

and, if necessary, easy to clean. 

Complete harmonic systems for operating theatre 

ceilings 

In addition to the hygienic aspects, special functional 

requirements must also be observed when constructing 

operating theatres. Ceiling supply units, video 

management systems, lighting systems and ventilation 

components, etc. must be integrated and combined 

within the ceiling to create a complete, harmonious 

system. Hygienically perfect, highly functional and 

aesthetically pleasing. 

It should be noted that clean rooms with classes 1 to 

5 according to ISO 14644-1 require a high filter area 

and the use of ceiling elements is not always possible. 

Clean rooms with horizontal displacement flow form an 

exception to this.
