Glazing is possible within the wall system in various individual sizes and with any preferred placement. The glass may be fitted on request with fire and X-ray protection. The open room arrangement thus generated provides a friendly, pleasant atmosphere. Room-high glass walls in modular form enable optimum observation of patients in intensive care units. Additionally, venetian blinds may be built into the insulating glass wall system. The individual panes are butt-jointed. The insulation glass panes are given a silicone seal.
