uPVC inline-sliding patio doors

Bespoke made for that perfect fit..

uPVC Patio Doors/Inline Sliding Doors are often chosen as a simple means of accessing your Garden, Patio or Balcony.

The two main distinct advantages of patio doors are the increased glass area which is achievable with a central meeting stile of as little as 30mm and simple sliding operation that does not encroach on either the inside of your home or the external garden area.

The simple operation means you can slide the door open as little or a far as you require with no fear of them blowing shut or being damaged in windy conditions.
