OWAtecta® metal ceilings

OWAtecta® are ceiling tiles with galvanised steel sheet on both sides.
The range, with fine gradations in the design, offers a varity of design options. Tiles with various hole patterns are available to optimise acoustics. This ceiling system is ideal for all installation situations – not just for new buildings, it is also perfect for renovation projects.

Perforations
OWAtecta® metal tiles are available in a range of perforations: from coarse to fine perforations. There is a tile to match your acoustic requirements and your proposed designs.

For special tasks

Positive/negative pressure ceilings
Determination of pressure tightness of suspended ceilings following DIN EN 1026 and DIN EN 12207
Clean room ceilings do not just qualify through their emission behaviour. What is also decisive is how they separate areas with lower and higher purity classes and react to different air flows occurring in the clean rooms. The separation is achieved by two different concepts: the displacement- and pressure difference concepts. In both cases the suspended ceiling system must be able to contain the different pressures of the clean room, i.e. the suspended ceiling should have as few leaks as possible. To this end, the joints between the ceiling tiles are carefully sealed, as is the connection between edge trims and ceiling tile and between edge trims and wall.
To classify the OWAtecta® S 22 and S 31 ceiling systems, the Fraunhofer IPA in Stuttgart carried out pressure tests based on DIN EN 1026 and DIN EN 12207. Both ceiling systems were mounted in a test box specially designed for this purpose and sealed airtight. In addition, the standard OWA Opal integrated lighting was installed in a grid of the ceiling system and likewise sealed airtight. The systems were then exposed to positive pressure of up to +80 Pa and negative pressure of up to -50 Pa and leak rate of the test specimen determined.pdf
>> The result: the OWAtecta® S 22 and S 31 systems demonstrated their qualification for air permeability "Class 4". Aside from the air tightness tested, the S 31 ceiling system also met the requirements for air purity in clean rooms (see “Ceilings for clean rooms”) and is ideally suited for use in a range of clean rooms and clean room areas.

Hygiene-sensitive areas
Unproblematic sterilisability according to the DGHM method
It must be possible to carry out easy disinfection of medical and hygiene-sensitive areas at any time. Unperforated metal ceiling tiles from OWA are ideally suited to this requirement, since they permit problem free surface disinfection. OWAtecta® (L0) is ideal for use in hospitals (OP areas, intensive care wards and patient rooms) and other sterile and hygienic areas. The Institute for Medical Microbiology and Hospital Hygience of the Philipps-University Marburg carried out extensive tests in this regard – practical, analogously and in accordance with the requirements of the German Society for Hygiene and Microbiology (DGHM).
Eight test bacteria were used in the stress test for the disinfection procedure:
- Staphylococcus aureus Pseudomonas aeruginosa
- Enterococcus faecium Proteus mirabilis
- Enterococcus hirae Candida albicans
- Escherichia coli Aspergillus niger
Representative active groups were tested for the surface disinfection in hospitals. This ensures that other disinfectants from the VAH list can also be used. The values measured produced a reduction of 6 log levels for all bacteria tested. The result exceeds the reduction demanded by the specialist associations of at least 5 log levels for disinfecting preparation.
