Highly engineered aluminium sliding doors

With contemporary square edge 83mm profile and extreme panel sizes, SUNFLEX UK SVG83 is a giant amongst aluminium sliding doors and one of the most popular systems in the range.

The highly engineered doors offer the ultimate in smooth, effortless operation and are ideal for creating large glazed openings in any type of project, from extensions and renovations to complete new build homes.

The SVG83 offers the highest levels of manufacturing quality, security and protection from the elements, and can be configured to your exact requirements for aluminium sliding patio doors.

Additional internal reinforcing sections ensure even the largest panels are suitable for the harshest of climates without increasing the sightlines, whilst the fully recessed level (DDA compliant) threshold is achievable without compromising the weatherproofing of the doors.

Every SUNFLEX UK sliding door is manufactured by hand in our own factory, ensuring the performance you would expect of a SUNFLEX UK system.

  • Suited to any location With internal reinforcing, the SVG83 offers the widest range of panel size options in even the most exposed locations.
  • Effortless usability With highly engineered stainless steel running gear and advanced track design, the SVG83 is capable of almost effortless operation, even with oversized panels.
