The film from which two-level stretch ceilings are made is a PVC film that has certain physical and chemical characteristics. Its thickness is 0.17-0.22mm. This PVC film can be completely different in texture and color shades (matte, semi-water (satin), metallic, glossy, under marble, etc. p.). The beneficial properties of stretch ceiling systems are their fire safety, moisture resistance, speed of installation, the strength of the canvas (up to 100 kg/sq. m), convenience in use (not required special care), the durability of the structure, etc. The canvas over time does not lose its color and other qualities, is easily mounted and dismantled if necessary. Its service life is more than 15 years.
