The false ceiling will have the following values: ɑw* __________e NCR* _________ * The acoustic characteristics of Atena products have been tested in accordance with ISO 10534, by an independent certified laboratory, the results on the acoustic absorption of the individual models have therefore been calculated using the ALPHACELLR software that uses the TIMM method for forecasting acoustic performance of pore-elastic multilayer materials. This is a system that takes into account the air resistivity, the porosity, the tortuosity and viscosity, the thermal characteristics and the permeability of the materials, which constitute the panel under test. The sound-absorbance and sound-impedance values of the panels depend on a series of factors such as the percentage of perforated area, the type of absorber / acoustic insulation coupled to the panel and the plenum value. Please therefore request Atena the values of ɑw and NCR or db to be reported in the specifications.Following models have been tested and certified in accordance with EN ISO 354:

The system complies with the Minimum Environmental Criteria DM 11 October 2017, the specific applicable standards UNI EN 13964 and 14195; does not release hazardous substances into the environment including formaldehyde. Painting and / or sublimation will be performed with substances free from Volatile Organic Compounds (VOCs). All products and components supplied will be accompanied by D.O.P. EC Declaration of Performance in accordance with the European regulation of construction products 305/2011. The artifacts will be recyclable and in their entirety derived from the use of materials from recycling processes, with content of recycled material, calculated for each type of product, compliant with CAM requirements and declared as required by the ISO 14021 standard. The false ceiling system contributes to obtaining credits for the design, construction and sustainable and efficient management of buildings according to the LEED protocol and according to the BREEAM and ITACA protocols for cross-cutting aspects.

NOTES: Atena Spa has adopted a quality management system in compliance with the UNI EN ISO 9001 standard.All Atena false ceilings are produced for indoor applications in compliance with the specific applicable technical standards and with the requirements of the “Norme Tecniche per le Costruzioni” NTC 2018 DM January 17, 2018 and relative circular; the performance properties declared in the relative D.O.P. are insured by Atena S.p.A. provided that the false ceilings are installed in the environmental conditions, for which they have been designed and have been subjected to the normal recommended maintenance activities. Specifically, false ceilings as non-structural construction elements must be appropriately sized in order to withstand with adequate security all those actions that can induce states of solicitation to the building; thermal, humidity, etc., in relation to the installation site, the intended use of the building and the technical characteristics of the project. It is therefore recommended to check with the Atena technical office the specific environmental conditions to which the product will be subjected in order to choose the most suitable materials for the installation site. In the case of outdoor installation, false ceilings are not within the scope of a harmonized technical standard and therefore are not subject to regulation 305/2011. They are in any case subjected to the NTC 2018 and to the safety checks of civil constructions and therefore they must be specifically sized according to the environmental conditions of the installation site, to the structural characteristics of the building and to the project specifications.
