Our core competences are focused on the fields of acoustics and fire protection; our products are tested in accordance with the latest European standards and are available in a wide variety of different formats, colours and surface structures.
As the manufacturer we consider it our task to make approved ceiling and wall systems available to planners, clients and public authorities for them to accomplish the building they envisage; these systems are designed to fulfil a multitude of requisite boundary conditions such as acoustic properties, fire protection, light reflectance, stability, flexibility and above all the individual needs and demands of the user.
In the field of glass acoustic solutions there are, in addition to grid ceilings, seamless glass acoustic ceilings available with a wide variety of surface structures.
And we are also able to offer you seamless, acoustic cooling ceilings; in addition to a homogeneous surface they fulfil all the requirements placed on room acoustics and cooling performance.
It is possible to install our products made of metal as acoustic grid ceilings in popular formats or as acoustic core panels for cooling ceilings.
We are able to offer you acoustic partial areas / acoustical clouds made of glass as well as metal and acoustic foam. Our acoustic foam ensures the success of diverse formats through to and including free-forms and three-dimensional shapes. It goes without saying that in addition to ceiling systems, acoustic partial areas and cloud solutions we also offer wall absorbers. This product is ideally suited to optimize the acoustic environment, in particular in rented properties. We hope that our new homepage provides you with a platform that will help you to choose the most suitable product for your requirements.
ACUSTICS - ARCHITECTURAL DESIGN DIMENSION
Human beings perceive sounds more directly and with an immediacy not equalled by any of our other sensory systems. Sound waves of different frequencies penetrate the inner ear (cochlea) and are deciphered in the nerve cords of the brain; this represents one of the most complex learning processes that human kind has undergone throughout our evolution to date.
The ear is able to perceive 10 octaves, by contrast the eye can only perceive components of a single octave. The eye can afford a higher level of inaccuracy, because in contrast to the ear it can scan a piece of information many times over. However, the spoken word is a brief, singular event, which it is practically impossible to articulate twice in precisely the same way.
During the deciphering process the ear has to work reliably and precisely straight away. Hearing just once must suffice, because a second later the person speaking has spoken several more words. We repeat this experience every time we hold a conversation. Every subtle inflection in the voice can contain important information about the person speaking, which is irrevocably lost if it is not grasped precisely at the instant it is uttered.
Based on this understanding we develop and produce effective acoustic building materials in close cooperation with scientists, clients, architects and contractors. Utilizing these high-quality materials facilitates optimum speech intelligibility in our built-up environment. At the same time, the design options available with regard to material, surface, colour and shape are so varied that it is possible to efficiently combine the demands placed on man and an eco-friendly architecture with one another on the basis of the latest scientific findings.
Since the devastating fires in the Middle Ages that often raised whole towns to the ground, distressing experiences have led to an ever-deeper understanding of passive, preventive fire protection. Today, the importance of fire protection anchored in German building regulations is made clear in §17 of the Model Building Code:
“Structures and installations must be designed in a manner that prevents fires starting, stops fire and smoke spreading, ensures people, animals and tangible assets can be saved and makes effective firefighting measures possible.”
German building regulations and the corresponding implementation regulations contain binding requirements governing which building materials or rather which building material classes are permitted to be used in the respective buildings and parts of buildings. Building materials are classified in building inspectorate approved classes “non-combustible, flame retardant and normally flammable based on standardized fire tests that lead to the corresponding building material classes A2, B1 and B2.
The field of application for the respective building material class is based on the philosophy: the higher or bigger the building, the higher the number of people in the building, the greater the demands placed on the building materials used.
That applies in particular to multi-storey buildings, hospitals, homes for senior citizens, schools, kindergartens and sports stadia as well as other public buildings in which it must be anticipated there is a large number of people present.
Fire protection affords exit and escape routes within buildings paramount importance; this is because on the one hand they allow people to leave the building safely and on the other they enable emergency services and firefighting teams to access the building long after a fire has started.
Consequently, Class A non-combustible building materials only are used in escape routes, which in addition to their actual reaction to fire must also fulfil requirements with regard to the development of smoke and the creation of toxic gases:
our acoustic building materials made of metal and the inorganic expanded glass granulate panel Mikropor G A2 fulfil the most stringent demands, for which the corresponding building inspectorate approval certificate is available.
In Germany, verification of compliance is provided in the form of a so-called general building inspectorate approval or a as general building inspectorate test certificate of building material class A2.
In Switzerland, the metal and glass acoustic building materials fulfil Class 6q.3 requirements; in Austria the glass and metal acoustic building materials achieve classification A “non-combustible”.
It goes without saying that if a composite material is explicitly required that fulfils class A2 requirements, the corresponding A2 core panels and coating materials are available with the respective test certificates verifying the compliance of the A2 composite material.

LIGHT REFLECTANCE VALUE
The homogeneous and non-directional surface of our Mikropor acoustic panels offer a further decisive advantage: thanks to this surface our products offer a proven light reflectance of 92%; that means it is possible to achieve energy and heat load savings by using daylight for longer. Furthermore, the homogeneous and non-directional surface has a calming and relaxing effect on the user.
FORMAT - EVERYTHING IS POSSIBLE
Our Mikropor G acoustic panel made from expanded glass granulate allows us to offer you small format grid ceilings, such as from 625 x 625 mm through to large format ceiling areas, for example 2500 x 1250 mm and 1250 x 1250 mm. Based on an untrimmed 2500 x 1250 mm format we are able to provide you with all the axis and panel formats you require ex works.
You can combine all standard formats to create the desired ceiling grid you wish. The ceiling systems are delivered to the building site prefabricated and sized according to the substructure. What’s more, our Mikropor G acoustic panels made from expanded glass granulate can easily be made to fit on site without any difficulty. All that is required are commercially available tools. There are no special protective measures to observe during processing work, such as when working with mineral fibres, for example.

Out expert sales representatives are pleased to be at your disposal at any time to provide you with a sample.
LIFESPAN
One of the main benefits of our acoustic panels is to be found in the suitability of their surface to be cleaned. It is possible to clean localized soiling on surfaces using water and normal washing up liquid. If the ceilings have turned yellow or become dirty over the years, which is actually quite normal for all acoustic ceilings, we are able to either clean or even refurbish them while they are still installed. In cases such as these we create a new coating on site by applying a layer of our acoustic paint to the surface; this treatment does not impair existing acoustic properties. We are able to repeat this process as many as four times.
Based on normal usage with smokers, for example, it is reasonable to assume that the ceilings will need refurbishing after 8-10 years. Consequently, it is possible to assume a lifespan of 32-40 years. This option is not available with other surfaces. This is because dirt and soiling do not build up solely on the surface of, for example, perforated acoustic ceiling systems (metal or drywall), but also in the holes and, as a consequence, in the acoustic fleece. This soiling can only be removed with a great deal of effort. It is true that when perforated surfaces are washed the particles of dirt are removed from the surface, however, the dirt sitting in the fleece is spread back onto the surface over and over again. Furthermore, cleaning perforated surfaces is considered to be rather difficult due to the hole patterns.
