K·LINE Galandage system

Galandage sliding door concealed within the wall

The sliding panels move into the wall cavity, freeing up almost the entire opening and creating a more seamless connection between your home and the terrace, garden or covered outdoor area.

The difference becomes clear when you open it: the panel slides into the wall instead of remaining visible and taking up part of the opening.
What it is

A sliding door with concealed panels

As the door opens, the panels slide into a purpose-designed space within the wall.

Where it works best

Terraces, gardens and wide openings

Particularly useful when you want a stronger sense of continuity between indoors and outdoors.

Before you decide

It must be coordinated with the building work

The area where the panels are concealed needs to be properly planned as part of the construction.

What is a Galandage sliding door?

It is not simply about opening a door. It is about making the barrier disappear.

A Galandage sliding door is designed so that its panels slide into the wall. Unlike a conventional sliding door, the panels do not have to remain visible and occupy part of the opening when the door is open.

It is particularly well suited to living rooms opening onto terraces, homes with gardens, covered outdoor areas and projects where maximising the clear opening really matters.

Put simply: if you are looking for a sliding door that disappears into the wall, you are looking for a Galandage system.
A real Galandage installation

Closed, partially open and fully open

The easiest way to understand the system is to see what happens to the panels. As they open, they slide into the wall and gradually free up the opening.

3. Fully open The panels no longer occupy the visible opening.
How it works behind the wall

This is what eventually disappears behind the finished wall

Before the internal finish is installed, you can see the actual structure of the system. The concealed pocket is part of the overall construction and must be properly coordinated with the building work.

01

We assess the opening

Dimensions, number of panels, configuration and relationship with the building work.

02

We plan the concealed pocket

The wall needs enough space to accommodate the sliding panels.

03

The finish is integrated

The building work conceals the structure, leaving only the finished result visible.

Single-panel Galandage

The same principle also works for simpler openings

Not every Galandage system requires several panels or a large glazed composition. This project shows a single sliding panel in three different positions.

Fully closed single-panel Galandage sliding door
Position 01

Fully closed

The panel closes the opening and separates the two spaces.

Partially open single-panel Galandage sliding door
Position 02

Partially open

The panel begins to slide into the concealed pocket within the wall.

Fully open single-panel Galandage sliding door
Position 03

Fully open

The opening is freed up and the panel no longer occupies the passage.

Benefits of the Galandage system

A wider opening and a cleaner connection between spaces

The main advantage is not purely visual. It changes how much of the opening you can actually use when the door is open.

01

Frees up the opening

The panels can disappear into the wall instead of remaining visible and occupying part of the passage.

02

No swing space required

It does not take up indoor or outdoor space in the way a hinged door does when opening.

03

Greater visual continuity

Particularly effective for connecting a living room with a terrace, covered outdoor area or garden.

04

Made for the project

The configuration is selected around the opening, the construction and the actual requirements of each home.

Opening configurations

There is more than one way to configure a Galandage system

Depending on the project, the system can be designed with different numbers of sliding panels and tracks. The right choice depends on the width, the space available for concealing the panels and the clear opening you want to achieve.

Special projects

Corner Galandage systems for opening up two façades

On suitable projects, a corner solution can be considered to free up the meeting point between two sides and completely transform the relationship between indoors and outdoors.

This type of configuration needs to be considered from the early stages of the project, taking the structure, building work and glazing configuration into account.

Beyond the concept

The final result also comes down to the details

A Galandage system is not simply a sliding panel disappearing into a wall. The configuration, locking detail, finishes and coordination with the building work all contribute to the result.

Before you decide

Does a Galandage sliding door make sense for your project?

It is not the right solution for every opening. We would rather be clear about that before proposing building work that does not make sense for your home.

You want to maximise the connection with a terrace, garden or covered outdoor area.
You are building or renovating and can coordinate the glazing installation with the construction work.
You value a clean, integrated architectural solution.
The wall construction can provide enough space to accommodate the sliding panels.
What about an existing renovation?

It may be feasible, but the wall construction, available space and actual scope of the building work need to be assessed. A Galandage system should not be quoted blindly.

Technical information without losing sight of the project

The final configuration depends on the dimensions, number of panels, glazing, building work and the specific requirements of the property.

Configurations

1, 2 or 4 panels

Different arrangements to suit the opening and the requirements of the project.

Sliding system

1 or 2 tracks

The configuration is selected according to the number and movement of the panels.

Large dimensions

Up to 4,600 × 2,450 mm

Indicative maximum dimensions depending on the exact configuration.

Project

Bespoke assessment

The glazing system, concealed pocket and construction detail must be properly coordinated.

Maximum dimensions, performance and available options must be confirmed for the specific configuration of each project.

Questions about Galandage systems

What you should know before requesting a quotation

What exactly is a Galandage sliding door?
It is a sliding door whose panels move into a purpose-designed concealed area within the wall. When open, the panels can disappear from view and leave a much cleaner, more usable opening.
Is Galandage the same as a sliding door concealed within the wall?
Galandage is the term used for this type of system, where the sliding panels disappear into the wall construction. It may also be described as a concealed sliding door, a pocket sliding system or a sliding door recessed into the wall.
Can a Galandage system be installed as part of a renovation?
It may be possible, but this depends on the wall construction, the available space and the scope of the renovation. The opening should be assessed before a specific solution is proposed.
Does it need space inside the wall?
Yes. The sliding panels need a concealed pocket within the wall. The exact construction depends on the selected configuration and the building work itself.
How is it different from a conventional sliding door?
With a conventional sliding door, the panels still occupy part of the opening when the door is open. With a Galandage system, the panels slide into the wall to create a much wider clear opening.
Can a Galandage system be designed for a corner?
Special corner configurations are possible on suitable projects. The glazing system, structure and building work all need to be considered before feasibility can be confirmed.
Does Alustetic install Galandage systems throughout Spain?
We do not offer installation throughout Spain. We work from Vilanova i la Geltrú and assess projects within our installation area according to location, type of work, access and installation requirements.
What information do you need to assess the project?
The project location, approximate dimensions of the opening, photographs of the space and whether it is a new-build project or a renovation. This information allows us to give much more useful initial guidance.
Tell us about your project
