Tile functions
OWA has a comprehensive product portfolio, providing suspended ceiling systems suitable for various buildings, interiors, or rooms. The specific function or application area influences the type of ceiling tiles required. Please review the different specification criteria below before exploring our ‘products’ page, where you can filter results using numerous accessible categories.
European and international standards regulate building products, including ceiling items such as mineral tiles, metal tiles, and baffles. The relevant standard is BS EN 13964 ‘Suspended ceilings – Requirements and test methods’. The European Construction Products Directive includes these products, which come with CE marking and a declaration of performance (DoP). Additionally, in the UK we include a UKCA label on the product packaging.
Sound protection
Increasing noise pollution in modern life emphasizes the importance of sound protection in buildings. OWA offers a range of quality acoustic solutions to address room and building acoustics.
- Room acoustics involve controlling sound within a room. A complex task gaining attention from clients, planners, and architects. Flexible workstations and open-plan offices, which promote communication, make this challenging. Above all, pleasant office acoustics are crucial in creating an environment conducive to both communication and concentration, making sound-absorbing acoustic ceiling tiles essential for reducing reverberation time.
- Architectural acoustics examines how structural conditions influence sound transmission between rooms:
- Airborne sound insulation aims to prevent sound energy from one room reaching those above and below. Therefore, enhance the sound insulation of a ceiling slab, such as reinforced concrete floors or timber beam floors, by adding a suspended ceiling that acts as an acoustic layer.
- Partitions that do not extend to the ceiling slab can affect sound insulation between adjacent rooms, allowing sound to transmit through the ceiling cavity. Equally, the choice of ceiling tile acoustic specification can impact privacy and noise transmission between areas.
- Furthermore, sounds from the ceiling cavity or roof, such as noise from rain, water pipes, ventilation, and air-conditioning, can be significantly reduced with an OWA ceiling system.
Fire protection
- Reaction to fire is tested according to BS EN 13501-1, with building products classified based on their fire behaviour. An accredited notified body must issue a certificate to verify the fire behaviour classification. Mineral tiles from our OWAcoustic range are classified as A2-s1,d0.
- Fire resistance involves testing the suspended ceiling system and the load-bearing structure above it, classified according to BS EN 13501-2. Firstly, the aim is to prevent the passage of fire from bottom to top or vice versa for as long as possible. Conversely, systems are classified according to their fire resistance duration. Our certified S3 tile and grid system, featuring 24mm tee grid, Mezz pro tile and perimeter trim, provides 60 minutes of protection under a steel C-profile mezzanine floor, in compliance with BS 476: Part 21.
Positive / negative pressure
Cleanroom ceilings are not just identified by their emission value. The ceiling system may have to withstand potential pressure differences. In this instance, the ceiling must be as leak-free as possible. The joints between the 600×600 ceiling tiles, the wall trim and tiles and between the wall trim and wall will need to be carefully sealed.
- Our OWAtecta S22 clip-in system was tested at the Fraunhofer IPA in Stuttgart. The pressure checks were based on DIN EN 1026 and DIN EN 12207. We installed the ceiling system into a test rig specifically designed for this purpose and hermetically sealed it. Also, we installed a standard integrated light (OWA Opal) in place of a ceiling tile and similarly hermetically sealed it. We subjected the system to a positive pressure of up to +80 Pa and a negative pressure of up to –50 Pa and determined the leak rate of the installation.
Resistance to humidity
In some application areas such as swimming pools or changing rooms with showers, the ceilings experience high levels of moisture. The moisture level, known as relative humidity (RH), always depends on the room temperature. For these application areas, it is important to use the right ceiling system.
- We have developed special ceiling solutions that meet the highest requirements. Depending on the product range, thickness and version, our suspended ceiling tiles are resistant to humidity with a relative humidity up to:
- 90% peak
- 95% peak
- 95% permanent OR
- 100% peak
The regional climate and local conditions determine which resistance to humidity value the selected product needs to have. If in doubt, we would be happy to help you select the right product.

Hygiene
Hospitals, laboratories, and other sterile spaces demand materials that prevent bacterial and mould growth and allow for easy cleaning and disinfection.
- OWA mineral ceiling systems – For application areas where hygiene is critical, we offer suspended ceiling tiles that posses varying hygienic properties, such as:
- Cleanroom classification up to ISO 3 (ISO 14644-1)
- Disinfectable
- Prevention of the growth of fungi and spores as well as bacteria and viruses.
- Extremely low filter effect. Therefore, less dirt settles on the surface and the ceiling stays looking as good as new.
- OWA metal ceiling systems – It must be possible to disinfect medical and hygiene-sensitive areas easily at any time. Therefore, plain metal tiles are perfect since they allow easy surface disinfection. OWAtecta (L0) is ideal for use in hospitals and other sterile and hygienic areas.
Cleanroom
Ceilings in cleanrooms must emit minimal airborne particles, adhering to BS EN ISO 14644-1 standards. Our metal tiles and many of our mineral tiles are suitable for application areas requiring high and very high levels of air purity.
- Metal tiles – With a classification up to ISO 1, OWAtecta metal ceiling systems comply with the threshold values of BS EN ISO 14644-1 in up to nine of nine classes (ISO classes 1 – 9). Therefore, they qualify for many cleanroom areas, such as in precision engineering, optical industries or in high-tech electronics production. Numerous tests by the Fraunhofer IPA in Stuttgart confirm this classification.
- Mineral tiles – Some of our tiles achieve a purity level up to ISO 4 and two achieve ISO 3 (according to BS EN ISO 14644-1). Similarly, they too are suitable for many cleanroom areas. The tiles constituent elements are dense and compact. Subsequently, for this reason additional edge sealing is not necessary.
