Aluminium glazing
More glass, less frame.
A sliding door runs one or more large panels past a fixed pane, or past each other, on a track. Because nothing folds, the frames can be much slimmer than a bifold's and each pane of glass much bigger — so when the doors are shut, which in a Welsh winter is most of the time, you see the garden rather than the aluminium.
The trade-off is that a slider never opens the full width. A two-part door opens roughly half; three- and four-part layouts open more. If you want the whole back of the house open in summer, a bifold is the better choice. If you want the view all year round, a slider usually is.
We survey the opening, agree the threshold and track detail with you, and fit sliding systems from Origin and Cortizo, made to measure for your opening.
Options
Layouts and details.
Three- and four-part
Wider openings, with panels sliding behind a fixed pane or meeting in the middle. More opening width without losing the slim sightlines.
Slim interlocks
The vertical where the panels meet is the part you look at most. The systems we fit keep it narrow — we can show you sample sections before you order.
Low thresholds
A flush or near-flush track for level access onto the patio, with drainage detailed at survey so rain has somewhere to go.
Glazing
Double or triple glazed, toughened throughout. Large panes are heavy, so delivery and lifting are planned before fitting day.
Colour & finish
Anthracite, black, white or any RAL colour, with dual-colour frames if you want a lighter shade inside.
In detail
Sliders or bifolds, honestly.
- Opening width
- A bifold folds back to open almost the whole width. A slider opens around half with two panels, more with three or four.
- The view when shut
- The slider wins: fewer verticals and larger panes of glass.
- Space
- A slider does not project into the room or onto the patio when open. Bifolds stack to one side and need clear space to fold.
- Everyday use
- A bifold's traffic door works like a normal door. A slider opens with one hand along the track.
- Price
- Depends on sizes and glazing rather than the type. If you are undecided, we will price both for the same opening.

I've had all my windows and doors fitted by Carl he came highly recommended by a family member. The whole process was very easy — Carl helped me through selecting and choosing my windows and doors, him and his team were very meticulous removing and fitting the windows and doors, everything was cleaned up and spotless at end of shift. Highly recommended.

Questions
Sliding doors: your questions.
How wide can aluminium sliding doors be?
Very wide. Individual panels can be well over two metres, and multi-panel systems can run across most extensions. The deciding factors are glass weight, the structure above and access to get the panels in — we tell you what is practical at survey.
Are sliding doors warmer than bifolds?
They tend to be, because there are fewer frame joints and more of the area is high-performance glass. Both are thermally broken and both will meet current Building Regulations.
Can a sliding door replace my French doors?
Usually. If the opening stays the same size it is a straight swap. If it is being widened, the lintel will need assessing and possibly replacing — we flag that at survey.
Do sliding doors need maintenance?
Very little. Keep the track clear of grit and leaves, and rinse the frames a couple of times a year — more often if you live close to the sea.
