The NASSAU 9000M door leaf is a combination of foam- and aluminium profile sections. Foamed sections are made of 44 mm thick polyurethane foam, with front and rear panels in either aluminium, hot galvanized or rustproof stucco structure. The rustproof version does however have a smooth inner side. The sections are 675 mm high.

The door leaves are filled with insulating fiber to provide a thermal barrier between front and rear. The foam sections of the leaves are constructed with a profile designed to conceal the section joints and provide extra longitudinal strength. The aluminium profile sections in the NASSAU 9000M are made of extruded of anodized aluminium profiles, with a choice of 15 different filling types. They also come in various heights, between 400 and 675 mm, making it possible to harmonize the door with the lines of the building.
