The SIMPLE system can now be a closed selfsupporting cell, a POD, to be inserted in the center of a room or open plan office, where you need to create a room such as a boardroom or private meeting room/ office. The POD is constructed from a metal structure supporting both the glass walls and ceiling, in a special sound absorbing material. The ceiling can be adapted to include sprinklers and air-conditioning ducts with LEDs lighting in the perimeter that illuminate the POD making it autonomous from lighting point of view. All materials used in the construction of POD are 99% fire retardant.
