Sliding patio doors, supplied and fitted across West Yorkshire
Sliding patio doors
Sliding patio doors are the right choice when you want maximum glass, a clear view of the garden, and no inward or outward swing to worry about. The leaves slide sideways on a track, so the furniture can stay where it is and the door doesn’t take up floor space when open.
Patio doors supplied and fitted in uPVC for standard openings and budgets, and in slim aluminium for contemporary renovations and larger openings where sightlines matter most.
When a sliding patio door is the smart choice
Wider openings than French doors
A typical patio door opening is 1.8 to 3.6 metres wide, sometimes more. French doors work up to about 2.1 metres before they start to feel small for the opening.
Rooms where you can’t spare the swing space
Kitchens with an island, small dining rooms, or any room where patio or French door swing would clash with furniture.
Where you want maximum glass with the door closed
Sliding patio door leaves are large panes of glass. Closed, they give you a floor-to-ceiling view of the garden. The sightlines are cleaner than French doors or even some bifolds.
Lower budget than bifolds
Aluminium bifolds are beautiful but they cost. A sliding patio door gives you similar impact at a lower price point for many openings.
Two-track and three-track options
Two-track sliding doors
Two leaves, one fixed, one sliding. The simplest and most affordable setup. The door slides in front of the fixed panel, so at any time you have half the opening cleared.
Three-track sliding doors
Three leaves, all sliding, stacking behind each other. Gives you a clearing of two-thirds of the opening at once. More expensive but much more impact on a wide opening.
Lift and slide mechanisms
Premium hardware where the door lifts slightly as you slide it, engaging a weatherproof seal when closed and sliding more smoothly when open. Worth specifying on larger doors and higher-end projects.
uPVC vs aluminium patio doors
Pick uPVC if
- Budget matters most
- The opening is standard size (1.8 to 2.4 metres)
- You want matching colour with uPVC windows
- Maximum glass area isn’t critical
Pick aluminium if
- You want the slimmest possible sightlines
- The opening is wider than 2.4 metres
- You’re specifying for a contemporary extension or renovation
- You want a RAL colour or a textured finish
- The door will be a feature of the room
What you get from a Calder patio door fit
Proper tracks and rollers
Cheap sliding doors fail at the track. Rollers wear, tracks deform, and the door jams. We fit ranges with hardened stainless rollers and reinforced tracks. Smooth operation is something you notice every day.
Multi-point locking
Standard on every patio door we fit. Hook locks, anti-lift bars, and internally glazed units.
Weather seals that hold
Brush seals, gasket seals, and proper thresholds that don’t let driving rain across the track.
Big panes, serious glazing
A-rated double glazing as standard. 40mm triple glazing on most ranges. Low-E coated, argon filled, warm-edge spacers.
Threshold options
Low or flush thresholds where level access into the garden matters, or standard thresholds where weather performance is the priority.
Integral blinds
Available on most of our patio door ranges. Sealed inside the glass, no dust, no cords, control via magnetic slider or electronic.
Colours and finishes
- uPVC: white, anthracite grey, black, cream, Irish oak, rosewood, any woodgrain effect
- Aluminium: any RAL colour, anthracite, jet black, textured finishes, dual-colour
- Glass: clear, toughened, acoustic, solar-reflective, integral blinds on request

Patio door FAQs
How wide can a sliding patio door be?
Two-track uPVC patios typically go up to around 3 metres. Aluminium can go wider, with multi-track and oversized leaves making 4 to 5 metre openings possible on the right system.
Are sliding patio doors secure?
Yes, with proper specification. Multi-point hook locks, anti-lift bars, internally glazed panels, and toughened glass are all standard on our ranges.
Can I have integral blinds in a patio door?
Yes, on most ranges. Sealed inside the glass so they don’t gather dust.
Do patio doors slide smoothly?
On quality ranges, yes. We don’t fit cheap ranges that jam or drag. Our rollers and tracks are specified to stay smooth for the life of the do
What’s better, patio doors or bifolds?
Different strengths. Patio doors give cleaner sightlines when closed and cost less. Bifolds give a wider clear opening when fully open but have more frame when closed. Depends on how you’ll use the space.
