Ecophon Hygiene Advance A C4 is a unique wall to wall, sound absorbing ceiling system for use in demanding environments. All the suspension components, made of acid-proof stainless steel, can endure daily wet cleaning with strong detergents and disinfectants. Examples of applications: areas with constantly high humidity and risk for corrosion; dish rooms and fish industry. The system is classified B1 and B5 for zone 4 according to standard NF S 90-351 and clean room classified according ISO 4.
The system consists of Ecophon Hygiene Advance A tiles, which have a core of high density glass wool fully encapsulated in a smooth high-performance film that is impervious to particles and water. The film is also dirt-repellent and resistant to most chemicals. The supporting structure is an exposed Connect T24 C4 grid made of acid-proof high-performance austenitic stainless steel to avoid stress corrosion that can occur on ordinary stainless steel. The weight of the system is approximately 3 kg/m2 (20 mm) and 4,5 kg/m2 (40 mm). The tiles should be secured to the grid with Connect Hygiene clips in order to withstand pressure during cleaning and to minimise dirt traps. For access to the plenum a special Connect Democlip is used together with a Ecophon Hygiene Advance A tile in 20 mm thickness. The Ecophon Hygiene Advance A C4 is a technical ceiling system which might have aesthetic variations that will not affect the functionality of the system.
