System and product description
Ecophon Hygiene Performance 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, are designed for areas with constantly high humidity and/or corrosive environments. Examples of applications: swimming halls, water parks and showers.

The system consists of Ecophon Hygiene Performance A tiles, which have a core of high density glass wool and a painted cleanable Akutex TH surface. The back of the tile is covered with glass tissue. The edges are primed. 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 3-4 kg/m². 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.
