Development and study of false ceiling panels using pumice and steel square mesh-case of Ethiopia

Abstract

False slab is the underside of the sloped roof truss, also known as false ceiling (FC), suspended ceiling, grid ceiling, drop ceiling (DC). These FC are used for both public and commercial applications within a room. These FC enhance the aesthetic of the interiors of the building and also reduces the volume of room while in use of air conditioning (AC). The reduction of ceiling height has its advantage with keeping rooms in cooler at the summer up to 16 0 C and saves electric bill up to 13%, but it's not much effective in movement for ventilation system [1−3]. The major challenging in ceiling panel is to reduce the weight and enhance the acoustic effect.
