Movable Wall Specification Guide for Architects

The first step in specifying a movable acoustic wall is to define the acoustic performance requirement for the space. This should be based on the intended use of the divided spaces, the client brief, and any applicable standards or regulations. For schools, refer to BB93. For offices, consider the level of speech privacy required. For conference and event spaces, consider the noise levels generated by simultaneous events in adjacent spaces.

Measure or calculate the clear opening width and height required. The opening width determines the number of panels required and the overall system weight. The opening height must account for the finished floor level, ceiling height, and the depth of the track housing above the ceiling. Structural limitations, existing services and ceiling construction must all be considered at this stage.

The size of the divided spaces must be considered in relation to the intended use. Meeting rooms should be sized to accommodate the required number of occupants with appropriate furniture. Classrooms must meet BB93 requirements for space per pupil. Conference rooms should allow for the required seating configuration. The stacking space for the panels when open must be incorporated into the floor plan — this is often overlooked at the design stage.

Top-hung operable wall systems require a structural support capable of carrying the combined weight of the track and panels. This is typically provided by a structural steel beam or reinforced concrete beam above the ceiling. The ceiling structure must be assessed by a structural engineer to confirm it can carry the required load. ModernGlide can provide structural loading information for all systems to assist with this assessment.

Choose between solid panel systems (MG100, MG200) for maximum acoustic performance, glazed systems (MG500, MG600, MG700) for light transmission and visual connection, or Crittall-style glazed systems (MG900) for a contemporary aesthetic. Consider whether an electric system (MG100E) is appropriate. The selection should balance acoustic performance, aesthetic requirements, budget and the specific needs of the building type.

Ceiling-mounted services — including lighting, sprinklers, HVAC diffusers and smoke detectors — must be coordinated with the operable wall track position. Services should not obstruct the track or the panel travel path. ModernGlide can provide track details and clearance requirements to assist with services coordination. This coordination should take place during the design development stage, not after services have been installed.

ModernGlide products are available through NBS Chorus, the UK's leading specification platform. Architects can access pre-written NBS specification clauses for all MG Series products through the ModernGlide NBS listing. Our technical team can also prepare bespoke NBS clauses for specific project requirements. Download NBS clauses and supporting documentation from our Architect Resources section.
