GLOBAL GREEN SUMMIT GREEN BUILDING KNAUF CASE STUDY Case : Knauf AMF helps create the perfect healing environment High performance acoustic ceilings from Knauf AMF have been installed in one of the largest hospitals in the United Arab Emirates. The hospital has recently expanded to offer additional specialist services. Thermatex Acoustic Medical is a 19mm thick perforated mineral tile which is ideal for healthcare environments. Its visible surface is covered with a white painted acoustic fleece with a high light reflection of 88% which helps reflect natural daylight into the rooms, reducing the need for artificial light. Areas with lots of natural light are known to increase the feeling of well-being. The ceiling tiles are fitted at the hospital using a concealed grid system which gives a sleek appearance. The tiles are fully demountable allowing access to the void above the ceiling for maintenance. Thermatex Acoustic Medical satisfies a number of strict hygiene requirements. The tiles are manufactured with an antimicrobial treatment to repel bacteria and fungi growth on the ceiling. The tiles have low air permeability, which helps prevent dust and dirt accumulating on their surface, reducing the risk of contamination. The ceiling offers high humidity resistance of up to 95% RH which means that even in damp conditions and high temperatures the tiles remain stable. Thermatex Alpha HD planks are installed in the hospital’s corridors. The planks were installed using a free span system with a concealed grid. The planks are easily demountable so maintenance openings are not required for access to the void above the ceiling. Alpha HD offers the highest sound absorption of NRC 0.90 plus 35dB sound attenuation which helps prevent unwanted sounds of voices, footsteps and trolleys moving on the hard floors in the busy corridors transferring through the ceiling void to adjacent rooms. It’s particularly important in hospital design as the walls may not extend up to the soffit due to the busy service layout. The planks are durable with an attractive matt white surface providing 88% light reflectance to help provide a uniform spread of light. The planks are available in different sizes up to 2400mm. Both Thermatex Acoustic Medical tiles and Alpha HD planks meet the highest fire resistance requirements, providing up to 120 minutes protection plus Class A rating as per ASTM E84 in terms of reaction to fire energetica INDIA · SEP | OCT15 71
