What makes our in-line sliding patio doors special

Slider24, a unique sliding patio door that matches to our pretty windows in performance, style and colour.

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 3.5 metres wide.

High Security

Our sliding patio doors are built to be strong, safe and secure. All glazing is 28mm toughened.

Ultion cylinder lock upgrade

A superb 11 pin security cylinder, with a £1000 break-in guarantee from Ultion. More information

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 Slider24 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 Slider24 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 UPVC 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.


Our new Heritage 2800 door frames can be ordered in beautiful authentic 'wood like' finishes in an amazing array of 30 colours and combinations. For zoomed up photos of all colours just choose a door and at the designer click on "Frame colour".

Internal magnetic blinds

Venetian Uni-Blinds are pernantly sealed inside the glass units, so no more cleaning or dangling cords. Operated by a cleverly-designed magnetic slider, at the side of the glass. A narrow rail ensures the linear movement of the slider. The blind is raised and lowered by moving the slider up or down and is tilted by slightly lifting or lowering the same slider.
Available in 10 colours. Anthracite grey and black are exclusive to Uni-Blinds and compliment the bi-fold anthracite grey and black powder coated frames.

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.
