Demountable Wall 108 is an architectural wall panel system that can be unmounted, relocated and reinstalled to fit different office layouts. It allows great flexibility for reconfiguring any office suites overnight without any noisy work. The demountable partitions with an easily re-locatable nature minimize the undesirable influents to other offices and save the time cost for the end-users. Unlike generic offices, the panels are set up uniquely to allow flexible seating arrangement which reflects the consumption of space more efficiently.
