C Max Direct Fix

C Max

C Max Direct Fix is a white painted, textured glass wool acoustic ceiling tile. Direct fix eliminates the need for an exposed grid and enhances the clean smooth monolithic surface. Designed for direct fix application to new existing gypsum board or other timber/metal battens. This is a high end tile with a high Noise Reduction Coefficient (NRC) to reduce reverberation time. The construction and design of the compounded, high density glass-wool results in a light weight, high performance ceiling tile which is user friendly and ideal for use in classrooms, offices, medical centres, lobbies and other commercial interiors. The glass-wool component also provides high thermal resistance coupled with low thermal conductivity which is excellent in helping maintain indoor temperature and also reducing energy consumption.
