A guide to choosing Sliding Patio Doors

Changing a solid door for one with more glass, or creating a larger opening in your wall to allow for a Sliding Patio Door is a great way of allowing more natural light into your home.


What to look for when buying a Sliding Patio Door

When choosing a Sliding Patio Door, there are many things to consider, such as: Which material to choose, Aluminium or uPVC. Inline or Lift & Slide, dimensions of the sightline, which colour, security and cost.

Which material to choose; Aluminium or uPVC

Due to the strength of aluminium, each door panel can be made wider than a uPVC door and the profiles tend to be slimmer, allowing for more glass and less frame. Excellent U-Values can be achieved with either a twin or triple track. Aluminium Sliding Patio Doors are available in a wide range of RAL colours and require very little maintenance to keep them looking good over a long period of time.uPVC Sliding Doors are energy efficient, offering cost effective thermal efficiency to reduce heating costs. They are very low maintenance and cleaning is simple using soapy warm water. uPVC Sliding Patio Doors tend to have thicker sightlines than Aluminium.

Which is more suitable, Inline Sliding or Lift & Slide Patio Doors?

For door sashes up to 1.5 metres wide, an Inline Sliding Patio Door will be ideal in either Aluminium or uPVC. For sashes over 1.5 metres wide and up to 3 metres wide, we would recommend an Aluminium Lift & Slide Patio Door. Operating Lift & Slide doors is easy, simply turn the handle through 180 degrees to raise the door on its track slightly and the doors then glide smoothly across the track.
