Latest Patents

Friedl holds a patent for a foam material element designed for sound-damping cavities. This invention is particularly relevant for light metal extruded profiles used in rail car construction. The foam material element consists of a sandwich structure with at least two layers: a resilient layer made of soft foam polyurethane and a heavy layer formed from a flocculated foam polyurethane compound. Before insertion into a cavity, the foam material element is compressed and sealed in an air-tight film. Once placed in the cavity, the film is opened, allowing the foam to expand and create a broad surface contact with the walls, effectively enhancing sound insulation.
