The right choice for every area of application
Lahnau Akustik offers the right solutions for practically every area of application.
With our acoustic panels made from recycled glass we provide you the option to create the best-possible acoustics in combination with a high-quality design, even in demanding areas such as sports halls.
Children and adults alike feel safe and at ease thanks to high levels of light reflectance, good acoustics and the right fire protection offered by our acoustic systems.
The advantages of these systems are obvious:
- It is easily possible to integrate practically all panel mounted devices in the system
- They can be installed independent of lights, sports equipment and radiant ceiling heaters
- Easy to remove
- Ball impact proof ceilings and wall cladding with a uniform appearance
- Complete system on demand
- We are happy to offer individual consultation
Ball impact resistance:
Building elements are considered ball impact resistant when they are able to withstand mechanical ball impact stress loads without significant changes occurring to the elements and their substructure.
Unlimited ball impact resistance:
The wall area from 0-2.00 m above the floor must always be formed to offer unlimited ball impact resistance. Even impacts by hockey balls are only allowed to result in slight damage to the surface.
Limited ball impact resistance:
All elements installed in the wall area (beginning 2.00 m above the upper edge of the finished floor), which can only be damaged by impacts from hockey balls, are considered limited ball impact resistant. A limited ball impact resistance also suffices for suspended ceilings. Ball impact proof is never spoken of, but rather ball impact resistance.
Test specifications:
DIN 18032, Part 3 Testing ball impact resistance. The requirements placed on ball impact resistance in DIN 18032 always apply to the whole construction, in other words the finishing elements (e. g., panels) and substructure. Considered on its own, there is no such thing as a ball impact resistant panel. Even when DIN 18032 is stipulated, the specifications contained therein fundamentally apply to a clear ceiling height of 5.50 m. The ball impact tests are carried out on ceilings at this height; consequently, they cannot be applied to lower ceilings. The ceiling must be ball impact resistant; in other words, the surface characteristics and the substructure must be durable and not exhibit significant changes in the face of all mechanical stress loads resulting from impacts by handballs and footballs.

The 5 steps required to successfully refurbish ball impact resistant acoustic ceilings made from ecologically sound, recycled building materials
- Step 1: Support during on site review of actual condition Step
- 2: Evaluate and assess the actual condition taking into consideration current requirements and DIN standards Step
- 3: Draw up and suggest a system solution and harmonize refurbishment work Step
- 4: Determine costs and draw up planning and tender documents Step
- 5: Carry out refurbishment work
Possible refurbishment options
Option 1: Cleaning and refurbishing
The visible appearance of the existing systems is improved in accordance with current requirements and state-of-the-art technology
Option 2: partial replacement
Damaged panels, for example by water, are replaced. After cleaning or refurbishing the panels the whole ceiling area is restored to a uniform appearance.
Option 3: Replace ceiling panels
The acoustic panels are replaced and the substructure retained. The condition of the substructure is inspected, then extended and reworked as required. Then new ceiling panels are installed.
Option 4: Comprehensive refurbishment
After analysing the actual situation the decision is taken that a completely new ceiling system is required. An individual solution is drawn up.
1. Cleaning
- Before cleaning with a damp cloth, carefully remove surface dust with a brush or vacuum cleaner.
- It is possible to remove localized soiling such as fingerprints or trails of soiling close to air outlets using a firm, damp sponge together with a commercially available household cleaner or Moisture-Clean (available as a powder from Lahnau Akustik) in the respective recommended concentrations.
- Then carefully wash down the cleaned surface with clean, clear water and dab dry with an absorbent cloth or paper (kitchen roll).
- We recommended you test clean an inconspicuous area each time before cleaning.
Professional refurbishment must be carried out using Wilhelmi acoustic paint WAF-R 86 (special colours WAF-R 87).
- Quantity used during refurbishment: 400-700 g/m² depending on the degree of soiling
- Ensure the room temperature does not fall below 12 °C when applying the coating; the relative humidity should not exceed 70%.
- Once applied immediately ensure the rooms are ventilated and dehumidified.
2.1 Refurbishment
If the acoustic ceiling has become heavily soiled after many years of normal use and can no longer be cleaned properly, it is possible to restore it to a condition virtually as good as new by applying a refurbishment spray.
When applied professionally in accordance with the manufacturer’s instructions the acoustic absorbency of the wall or ceiling surface is not impaired. The refurbishment can be repeated several times, if required.
Under no circumstances should emulsion paints be applied to the surfaces using a brush or roller, otherwise the sound absorbing properties will be lost.
It is only possible to guarantee the acoustic characteristics will be retained by engaging a professional company that uses the appropriate coating machinery to professionally apply the refurbishment spray, e.g.,
