In 1998, Internorm put the first aluminium entrance door with foam insulation core on the market. Next to four aluminium door systems, Internorm also offers two timber/aluminium door systems today. Our customers value the high-quality processing and individual design possibilities. In 2015 therefore, the 500,000th entrance door was produced.
