Curtain Walling

MX – Excellence in Façade Technology

MX is a complete curtain walling suite, offering specifiers enhanced thermal performance to meet the most stringent Building Regulations, and the widest choice of aesthetic options from a single system.

A variety of curtain wall applications are available using the same transom and mullion grid, giving specifiers the opportunity to vary the appearance of the building envelope, with all the design and construction benefits of one fully integrated system.

Combining Aesthetics with Functionality


The MX system successfully balances the aesthetic requirements of architects with the functional needs of contractors, developers and occupiers – simplifying specification, fabrication and installation to ensure the highest quality and cost efficiency.

Designers also have the benefit of consistent sight lines and interfaces across a project – whether the requirement is for low to high rise curtain walling, and ribbon, structural, beaded and sloped glazing.
