A2Coustic / A2irglass
Expanded glass granulate and perforated laminate
(sound absorbing) expanded glass granulate and laminate
Wilhelmi A2Coustic acoustic panels from Lahnau Akustik GmbH are made from recycled glass granulate and bound with inorganic binder. The front and rear sides of the acoustic panels are laminated with a perforated HPL laminate supplied by Resopal. Thanks to their extremely robust surface these acoustic panels are ideal for installing in wall and ceiling areas. The numerous different patterns available mean this product not only fulfils acoustic requirements it is also pleasing on the eye.

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 Download archive.
Constructions & details:

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.
Installation system with hat channels

- Panel lengths up to 2500 mm panel widths up to 625 mm; wider panel widths with added reinforcement on request
- Ceiling void remains accessible; all acoustic panels can be removed and reinstalled using tools; no need to push up into the void to remove
Lay-on / lay-in system with visible T-profile
- The ceiling system for a variety of grid dimensions; easy access to ceiling void
- Panel lengths up to 2500 mm, panel widths up to 625 mm with a T-profile width of 15 mm or 24 mm
- Square formats up to 1250 x 1250 mm can be installed without added reinforcement. Possible to remove and reinstall without tools
Cleaning Resopal surfaces
It is possible to clean surface dust using a dust cloth. A damp cloth is sufficient to remove adherent soiling (e. g., fingerprints); if necessary, you can also use a normal general-purpose household cleaner or vinyl cleaner.
Do not use abrasive cleaning agents or sponges to clean high gloss finishes.
If in any doubt, test clean an inconspicuous spot.
