Suspended ceiling systems play a key role in the control of the acoustical environment thanks to their acoustic surface core composition. The occupant of a space, be it an office, a classroom, a shop, or any similar environment needs:
- Intelligibility – to hear and to be understood
- Privacy – to not be overheard
- Concentration – to not be disturbed
The optimum acoustic climate will be obtained with the right combination of sound absorption and sound insulation, and can be supplemented by the use of active acoustics.
Knauf AMF acoustic ceiling tiles facilitate the acoustic functionality of a suspended ceiling by providing a range of tiles with varying NRC values (noise reduction co-efficient) which allow for both absorption and reflection of noise. The higher the NRC the greater the absorption of noise which reduces the overall noise levels and lowers reverberation, creating a more comfortable and productive working environment.
It is however important to understand the requirements of the acoustical space, in order to correctly select the best acoustic tile option. In a lively bar or restaurant more reflectance of noise may be the objective and an NRC of 0.50 may be more suitable.
Features and Benefits include:
- Humidity Resistance up to 95% RH
- Light reflectance up to 90%
- CAC up to 35
- Enviromentally friendly
- Moisture and fire resistant
Fire Protection Parameters and Fire Resistance Classification
The EN 13501-1 standard is used to assess and classify building materials according to their fire behaviour. It sets the requirements for the materials on the surface of building components, e.g. ceiling cladding, and their behaviour when in direct contact with radiant heat or flames.
The classification into combustible and non-combustible building materials doesn‘t describe the intrinsic behaviour of the material. The behaviour under fire load depends on the surface type and form, the presence of bonding agents, the processing technique used, etc. The certifications are therefore only valid for the building material or composite building material actually tested. Other compositions can exhibit a less favourable fire behaviour.
The A2-s1,d0 class corresponds to the national building-regulation term: “non-combustible”. AMF THERMATEX panels are classified as A2-s1,d0 in accordance with EN 13501-1 and are therefore “non-combustible”.
The material class is mostly printed on the rear of the panel as well as on the packaging labels.
Test certificates are available on request.
