Engineering Oversized Glazing Beyond Standard System Limits
Achieving a sliding door height of over 4.5m introduced a significant technical challenge. The required dimensions exceeded the standard tested height of the system, demanding careful engineering to ensure smooth operation, structural integrity and long term performance.
The presence of the mezzanine added further complexity, as the glazing formed a visual backdrop across two storeys and needed to align precisely with floor levels and internal sightlines. Stability, safety and accessibility were key considerations, alongside the requirement for discreet drainage and robust locking suitable for a family home.
How the minimal windows® Sliding Door System Was Integrated to Resolve the Project Challenges
The minimal windows® sliding door system was engineered to accommodate the exceptional height required at Kingston Road. A three track, three panel configuration measuring 4.6m high and 3.8m wide was installed, using reinforced 21mm interlocks to support the increased structural demands while maintaining ultra slim sightlines.
Subtle adaptations were made to the system design to enable reliable performance at this scale, including enhanced reinforcement and an integrated base drainage channel to manage water effectively without disrupting the clean architectural lines of the interior. A type 4 internal key locking system was specified to provide added security while preserving the minimal aesthetic.
Finished in a matt RAL 9004 powder coat, the frames sit comfortably within the restrained interior palette, allowing the double height opening to read as a single, sculptural element within the space rather than a collection of components.
