In the 1970s, a French inventor named Mr. Fernand Scherrer came up with a simple idea that changed the ceiling industry. Today, after more than 50 years, the concept is still the same – two components that transform your ceiling. These components are the track or frame or cornice (which are all different words for the same thing) and the membrane or film or fabric or vinyl (which are also all different words for the same thing). The profile is placed around the walls of the room and has an interior harpoon receiver. The membrane comes with an external female hooking harpoon already installed. To install it, the installer simply hangs the membrane’s harpoon on the profile with a straight spatula.
