Enclose the long side of your pergola in style with the Casa Maria 4m Aluminium Sliding Door. A set of louvred aluminium panels glide along a discreet dual-track top-and-bottom rail — overlapping in two planes as they slide — to form a solid, architectural wall you can open and close at will. It turns the open 4m side of your pergola into a sheltered, private space with the substance and finish of a permanent garden room.
Each panel is powder-coated aluminium in dark grey to match the Casa Maria pergola range. The panels slide along the dual track and overlap one another to open up around half the 4m span, or draw closed to cover the full side. Unlike a fabric screen, the sliding door gives you a rigid, weather-tolerant aluminium wall — ideal for the side that takes the most wind, sun or overlooking, or simply to give your pergola a finished, fully enclosed look.
✅ Will this door fit my pergola?
This aluminium sliding door set fits the 4m side of our manual LuxShade™ 3×4m:
|
✔ LuxShade™ 3×4m (4m side)
|
This door does NOT fit:
✗ The LuxShade™ 4×4m — it also has a 4m side, but it uses a different 4m aluminium door, not this one · ✗ Any 3m side (3×3m, 3×6m or SplitZone™ 3×6m) — use our 3m aluminium sliding door instead · ✗ Any MotaShade™ or EdgeShade™ model · ✗ The original 2.40m mid-beam SplitZone™ 3×4m. These use a different door and rail — please see the matching accessory for your pergola, or ask us.
Also enclosing the 3m sides? Your 3×4m pergola has two 3m sides as well — those take our 3m aluminium sliding door instead.

|
A solid wall when you want one — open when you don't Slide the panels across to close off the side completely, or overlap them to one side to open up around half the span. It's the difference between a breezy open pergola and a sheltered, private garden room — and you choose, moment to moment. |
|
Full privacy and shelter when it's closed Solid louvred aluminium panels screen the side from view and block wind and low sun, giving you genuine privacy and shelter rather than the open sightlines of glass. It's the choice for an overlooked garden or the windward side, where you want a proper enclosing wall. |
|
Smooth, effortless dual-track sliding The panels run on a dual-track top-and-bottom rail that keeps them aligned across two planes and gliding smoothly, so opening and closing the side takes nothing more than a gentle push — no lifting, no awkward handling. |
|
Built to live outdoors Powder-coated aluminium throughout resists corrosion and shrugs off the British weather, with no rust and no special upkeep — just an occasional wipe to keep it looking its best. |
|
A finish that matches your pergola The dark grey frames are designed to match the Casa Maria pergola frames and accessories, so the sliding door reads as part of the original structure rather than an add-on. |
|
Build the enclosure you want Add a sliding door to one side, or combine doors and screens around the structure to create a fully or partially enclosed outdoor room. Start with the side you use most and add more whenever you're ready. |
Closing off the long, most-exposed side of your pergola so you can use it later into the evening and the year, screening a neighbour's line of sight, sheltering the dining area from low sun, or simply giving your outdoor room a finished, architectural look. Because the panels slide and overlap on the dual track, you keep the flexibility to open up around half the side on a still, sunny day — and draw them closed across the full span the moment the weather or the mood changes.

Which pergolas does this 4m aluminium sliding door fit?
It fits the 4m side of the manual LuxShade™ 3×4m only. Importantly, it does not fit the LuxShade™ 4×4m — although the 4×4m also has a 4m side, it uses a different door. It also doesn't fit any 3m side (use our 3m aluminium sliding door), or any MotaShade™, EdgeShade™ or SplitZone™ model — these use a different door and rail. If you're unsure which pergola you own, please contact our team before ordering.
Does it provide full privacy?
Yes — when closed, the louvred aluminium panels screen the side from view, giving strong privacy and shelter from wind and sun. If you'd rather keep the view, our glass sliding door is the alternative; many customers use the aluminium door on overlooked or windward sides and glass where they want to see the garden.
How far does it open — do the panels stack fully away?
This is a dual-track system, so the panels slide and overlap one another across two planes rather than stacking fully out of the way. Closed, they cover the full 4m side; open, they overlap to one side to leave roughly half the span clear. It's designed to give you a solid, enclosing wall when you want it and a generous opening when you don't — rather than disappearing completely.
How many sets do I need?
Each set encloses one 4m side. Many customers start with the side that catches the most wind, sun or overlooking, then add further sets — or combine with our glass doors, windscreens and the 3m door for the shorter sides — to enclose more of the pergola over time.
Is it fully waterproof?
The aluminium door provides strong shelter from wind and rain across the panels under normal outdoor conditions. As a sliding panel system it is not a fully sealed, watertight wall, so some air and water can still pass around the edges where the panels meet and overlap.
