Architectural aluminium systems specialist, Technal, has launched MX Acoustic – a new design option for its MX curtain walling range, to help architects and specifiers satisfy more demanding acoustic requirements.


MX Acoustic has been developed as an option for MX Visible Grid and MX Trame Horizontale curtain walling, for applications where additional acoustic performance is required, such as hospitals, hotels, student accommodation, city centre apartments and buildings near airports and railway lines.


The system uses a 32mm to 42mm infill to achieve airborne sound reduction and reduce the impact of external noise pollution. It is available as both a flat façade or faceted up to 20° for the grid curtain walling and a facet of up to 10° for MX Trame Horizontale, which expresses the horizontal profiles.


Structurally bonded top hung concealed vents can also be supplied for MX Acoustic, and the system is fully compatible with Technal’s PXi door system and FXi casement windows.


In rigorous tests in accordance with BS EN 13830 for curtain walling, MX Acoustic Grid achieved 1200Pa for static water tightness, 2400Pa for wind resistance and level A4 for air permeability.


Technal’s MX curtain walling suite is believed to be the first in the UK to offer such a wide range of design options from a single grid system – giving specifiers the benefit of consistent sight lines and interfaces, and simplified specification, fabrication and installation for cost efficiency and reductions in time on site.


Options in the range include low to high rise curtain walling, visible grid, faceted, structural sealant, beaded and sloped glazing, and MX Trame, which allows specifiers to highlight the vertical or horizontal profiles across the building envelope with projecting aerofoil caps.


The MX system has already been used extensively in the UK and internationally since its launch, and offers enhanced thermal performance, consistent quality, concealed vents in a variety of configurations and a choice of depths to meet individual project requirements.
