Unique Features

Our XP Infinite is the ideal solution for projects with demanding requirements, meeting the trend of “transparent” architecture through extensive glass surfaces, with high thermal insulation, safety and modern design.

Its minimal design and its various innovative characteristics include the option of a moving corner post and a unique quadruple outer frame and bottom track that allow the doors to create a 75% clear opening. The XP Infinite is the ideal product for projects requiring wide spans for enhanced daylight, outstanding performance and maximum ease of use.


The system enables you to lock the door in any position when open. As the door lifts onto the ball bearings the quality of the system minimises the weight, meaning a glazed unit weighing in excess of 300kg can easily be slid to one side. The system is severe weather rated and boasts superb thermal performance. A slender 47mm sightline section is available on twin track systems, making it the ideal product for large spans, and ease of use whilst maintaining slender sightlines.

Moving corner post available

Lockable in any position

Unique, Quadruple 4 panel track available

Almost effortless to slide the door


  • Thermally insulated with polyamide thermal breaks, energy bar & insulation foam.
  • Innovative 24mm low threshold option with built-in drainage for non-exposed locations.
  • Twin, triple & unique quadruple outer frame and bottom tracks available.
  • Easy to operate with a lift and slide mechanism, which can be locked in any open position.
  • Reinforced slim-line 47mm interlock boasts unique indented profile internally that can be used as a handle to slide the door.



A twin track system offers two and four panel sliding doors with a 50% clear opening.

  • The quality and strength of our XP Infinite means we can manufacture and install a door well in excess of 5500mm x 2400mm split into just two panels. The door can be manufactured more than three metres in height, and twin track systems are available with a sightline of just 47mm.


Our triple & quadruple systems offer a typical sightline of 106mm and various, flexible configurations.

  • Three panels can create a two-thirds opening, or a middle sliding panel with two fixed.
  • Our unique quadruple track allows for four panels and a 75% clear opening, with all four panels stacking to one side, the perfect for solution for large spans in excess of eight metres.
  • For a wall of glass, six panels with three stacking either side offers both symmetry and a huge opening, the same principles apply to eight panels, which would create a hugely impressive sliding door that will create a huge feature within any property.


Whether you’re thinking a modern grey will complement your stonework nicely, or you want to make a statement with a bold colour, you’re in the right place.

If you’re looking for something secure and reliable as well as stylish, then our XP Infinite glass sliding doors are the perfect choice. The panels are injected with a liquid component, which sets rock-hard, making each panel light but solid as concrete.

Designed with security in mind, our aluminium sliding doors boast features such as:

  • Multiple lock points on the master door
  • Interlocking profiles on sliding panels
  • Anti-lift blocks in the head of all panels
  • The system is glazed from the inside


Our sliding doors are designed to be as safe as possible, so you and your family can use your doors with peace of mind. All of our doors are bespoke, so we can make sure that we install your bottom track as flush as possible. That way, there’s no unsightly upstand and no trip hazards.

Lift and slide patio doors are ideal for family homes as the doors can be locked in an open position so you don’t need to worry about those little fingers, whilst children plan in and around the huge, glass doors.
