Free spanning acoustic ceiling

Corridor acoustical ceiling is unique ceiling solution for narrow rooms and corridors. The acoustic ceiling planks are free spanning between the walls, free-span of up to 2.4 metres.


The gypsum ceiling is installed without any cross runners or suspension hangers. Therefore, a Corridor acoustical ceiling is extremely quick to install; 3 times faster installation than a traditional T-grid ceiling in a corridor.


Corridor is based on perforated gypsum – a sustainable building material. Corridor ceiling planks consist of materials that are 100% recyclable.
