What makes our in-line sliding patio doors special

As an authorised PatioMaster fabricator we ensure that every advanced sliding patio door is built to your exact specifications with attention to detail.

Door designs

There's nothing 'off the shelf' about our sliding doors. Each one is built to order, to your exact measurements and choices. Using our online door designer you can build your door with 2, 3 or 4 panes and 1 or 2 sliding panes in your chosen direction. Optionally, you could also have a midrail for a letterbox. Here is our unique on-line sliding patio door designer.

Mechanically joined - new feature

The exterior frame is now mechanically joined instead of welded, which is fantastic if you have limited access during installation as it can be unscrewed and taken apart. The frame will conveniently come fully assembled, as long as it's under 4 meters wide. This applies to all sliding doors ordered after 20th November 2017.

High Security

Our sliding patio doors are built to be strong, safe and secure. Each door is steel reinforced, secured with multipoint locks - six point locking system as standard, and has anti-jacking technology with all panels sliding internally, 28mm toughened glazing and extra reinforcing around the locks.

Ease of use and installation

Even though our doors are strong, robust and secure, they are easy to use. We've put the effort into the engineering so they are lightweight in operation, gliding smoothly and quietly on their tracks. Our doors are suitable for all types of homes from bungalows to high-rise. We've designed them for ease of installation, with slim stepped frames which minimises plaster cutback.


The PatioMaster door system is designed for appearance and for function, but also for durability. The good looks will not fade, they last year after year. Our doors won't split, crack or warp, and they'll stand up to the worst of the weather without issues. Maintenance is minimal and all that is usually needed is a quick wipe with a soft cloth using warm, soapy water.

Energy Efficiency (Approved Document L Compliant)

Our PatioMaster sliding doors have been designed to keep the warmth in and the cold out.
We use the same Argon filled A+ rated glass as we use in our windows.
We include weather-seals that prevent drafts and leaks, a thermally efficient multi-chamber PVCU-U frame for reduced heat transmission & strength and 28mm thermally efficient glass as standard with a special coating that reflects the heat back into the room. Our glass is filled with argon gas which is extremely effective in reducing heat loss as it's denser than air.


When specifying your PatioMaster sliding patio door you can choose a 2, 3 or 4 pane type, in various colours including white, cream, rosewood, light oak, anthracite grey & black. We also have a wide range of handle colours to compliment your new door.

Glass (Approved Document N Compliant)

All glass is toughened as standard in energy efficient sealed glass units with:

  • Inner pane – Pilkington KS
  • Outer pane – Pilkington Optiwhite
  • Gas filling – Argon Gas
  • Spacer bar – SuperSpacer
  • Thickness – 28mm
  • U-value – 1.20 to 1.22  

All toughened glass is approved to Kitemark: BS 12150.
In addition, you may also add Georgian bar, Square lead or Diamond lead decoration to your glass.


We have invested heavily in our machinery to ensure both accuracy and a high quality finish. Our quality control system ensures that each door leaves our factory to the highest standard.


Our sliding doors have reasonably low thresholds of 50mm (42mm to bottom of door sash), not including any cill. Lower thresholds than that have not been proven weather proof.
