NORTEC is Lindner’s calcium sulphate raised floor system for standard applications. Panels may be supplied with a steel sheet on the underside and are provided with an edge trim on all edges against impact and humidity. Lindner positions the system for a wide range of building types, from offices and public buildings to education, healthcare and industrial spaces.
