Acoustic panelling

Acoustic panelling effectively absorbs, reflects or disperses noise. Using acoustic panels you can achieve desired acoustic quality, including reducing reverberation time and improved listening conditions in a confined space. Acoustic paneling are combined using individual acoustic elements and materials, which create the interior paneling of the room in the planned design. There is a wide variety of finishes so that you can choose colour, type of perforation, and material.

Grena Recommended materials intended: Grenamat AL, Grenamat B, Grenamat C.

The Grena company can provide supplies and installation of materials for various designs of concert halls, studios, theatres and cinemas. Our materials have very good acoustic properties and are available in a wide range of finishes and shapes.
Materials are available in class A1, A2, B or C of reaction to fire.

Typical composition of acoustic panels made from Grenamat boards

For more information do not hesitate to contact our sale representatives. They will help you find a suitable type of acoustic panel or even prepare a proper acoustic projection. We also prepared to help you realize your project in cooperation with a specialized company.
We provide acoustic designs and measurements in collaboration with the AVA JH s.r.o. company.

Methods of jointing and mounting

H Profiles
Clips
Z profile Wood profile
Bolted joints

Usage of screws
Screwing through the surface layer.
Tolerance for screw shank must be maintained.
For countersunk screws, use washers to avoid tear of the surface foil.

 
Special clips and profiles - walls, ceilings
 
 

Attachment to wooden structures
Attachment of boards on a wooden supporting frame with the option to insert insulation. Easy alignment of the supporting grid with special washers and alignment of panels along all axes.

Bonding of boards to adjustable metal supporting profiles
Grenamat boards can be attached to metal profiles by our special bonding process which has been fully tested. This way, an invisible attachment to the structure is ensured.

 
Other options include attaching metal profiles by screws
Attachment withstainless clips
Bonding
Attachment with screws
