Wilhelmi acoustic panels from Lahnau Akustik GmbH are made from recycled glass granulate and bound with inorganic binder. The surface consists of a silicate based acoustic membrane and is sprayed with Wilhelmi acoustic silicate paint. The structure of the visible side is closed, non-directional and fine pored. The max. format of the stable, 18 mm thick panel core is 2500 x 1250 mm, which is easily manually processed.

We develop 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.

A variety of acoustics tests are available to download from the Downloadarchiv.

Overview of our standard grooves:
The wide variety of possible constructions makes it necessary to offer a broad portfolio of groove variants.

Acoustic panels from Lahnau Akustik GmbH are suitable for both T-profile substructures as well as for numerous substructures developed by us.
The PDF document contains an overview of the available variants.

Different grooves are possible on request.

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.,
