Installation of a stretch ceiling begins with a predetermined corner. With the help of fastening locks, the canvas is fixed 15-20 cm from all sides of the corner. Next, the film is carefully heated and pulled slowly on the fasteners. When heated, the surface area of the canvas expands by ten percent, when cooling, the canvas narrows and the absolute ceiling is obtained. During heating, it is necessary to monitor the elasticity of the canvas and exclude the possibility of overheating.
