Modernfold manufactures operable partitions, glass wall systems and accordion doors for interiors that need to change configuration over time. The Acousti-Clear® Demountable glass wall addresses a different kind of change from the operable configurations in the same family: rather than opening and closing daily, it builds fixed, acoustically separated rooms that can be dismantled and reassembled in a new layout when the plan itself changes.
Demountable construction
Panels are fixed in position rather than suspended for daily movement, and are joined through L, T and X posts, which allows enclosed rooms, corridors and corners to be assembled from the same set of components. Because the whole assembly is demountable, a tenant fit-out can be reconfigured without demolition or wet trades — relevant where lease terms are short, where the occupier expects headcount to change, or where the client wants the partition treated as furniture rather than as construction.
Sealing and acoustics
Top and bottom seals are engaged through a manual crank-activated system once panels are set in place. Acoustic ratings are 51 or 45 STC for glazed panels and 50 STC for solid panels, so glazed and solid panels can be combined within a single run where a room needs partial privacy without giving up daylight along its full length. Panels interconnect through convex and concave aluminum profiles with sealing lips that combine friction with a positive interlock.
Panel construction and dimensions
Panels are 4 inches (100 mm) thick in double-skin tempered glass with a minimum horizontal frame profile of 4.6875 inches (119 mm) and hanging weights of 10 to 11.5 lbs/sq.ft. Maximum height is 12 feet (3,658 mm), and panel widths range from 12 to 48 inches (305 to 1,219 mm) — the narrowest minimum width in the Acousti-Clear® family, which gives more freedom to resolve odd dimensions and close-out conditions against existing walls. Closure is by adjustable jamb, and access is provided through a glass pivot door.
Finishes and integration
Frame finishes include clear anodized, satin stainless anodized, and powder coat in white, black or standard RAL colors, with horizontal mullions and door hardware available as options. Since the Acousti-Clear® products share profiles and finishes, demountable rooms can sit alongside operable Acousti-Clear® runs in the same interior and read as a single system — a common arrangement where fixed offices open onto a divisible meeting or event area.
