Sliding Doors

A mini-guide for choosing the sliding pocket doors. How to understand the difference between the different models, to correctly calculate the dimensions of the door opening and the overall dimensions; how to choose and identify the type of frame on the basis of the door, the opening and walls. The box contains detailed information on each topic.

Understanding sliding pocket doors from A to Z

Which is the difference between an external sliding door and a sliding pocket door?

Unlike traditional hinged doors, sliding pocket doors allow to regain the space occupied by the radius of the door opening and help to create a larger and more welcoming environment, offering greater furnishing options. Eliminating the hinged doors, the home regains more space that can be essential for environments of reduced dimensions, benefiting of a more refined interior decoration.

There are two types of sliding doors:

In the former case, the door opens by sliding along the wall, while in the latter case the door opens by sliding inside the wall through an appropriate system commonly known as the ‘frame’. The frame of a sliding pocket door refers to a metal box that allows the door to slide inside the wall concealed from sight. Both solutions solve a space problem but, compared to the external sliding version, the sliding pocket door frees the space on the wall where the door slides, opening up greater furnishing possibilities. Depending on the type of frame adopted, several different opening solutions can be obtained.

A sliding pocket door system: what it is and how it works

The details of the metal structure specially designed for both solid wall and stud wall

The frame for sliding pocket doors is a metal structure enabling the door to disappear inside a wall (both solid and stud wall). The frame is made up of a box inside the wall, a sliding system (track) located in the upper part that allows the door panel to slide inside the wall and a vertical metal door stop that receives the closing door.

To qualify as a premium-quality product, the frame necessarily needs to comply with specific reliability and durability requirements.

  • Sturdiness: the frame must be as sturdy as the wall and it can be inspected to allow its maintenance without knocking the wall down.

  • Smooth and light sliding of the door: the runners and the track ensure smooth and light movements and can be easily replaceable if they get damaged.

  • Guarantee of a sliding internal passage without flexes of the metal sheet making up the frame eliminating problems in the door sliding.

  • Guarantee of a crack-resistant plaster solution: being an integral part of the wall, the counterframe does not alter the appearance and consistency of the wall.

  • Easy installation and maintenance: a frame that is easy to assemble and to install even by non-expert personnel guarantees and safeguards the product over time. This is possible thanks to a maintenance free track fully extractable which enables to retrofit accessories after the installation without having to break into wall.


To this aim, in over 30 years of research ECLISSE has developed a product boasting the following characteristics:

Calculating the dimensions of a sliding pocket door

To properly calculate the sizes of a sliding pocket door, it is first necessary to understand the difference between the terms ‘door opening’ (or passage size) and the ‘maximum overall dimensions’.

The door opening, or passage size, refers to the actual dimensions in height and width between the jambs (if present) and the level of the finished floor. A standard sliding pocket door has the same sizes as a corresponding hinged door. It typically measures 70 cm or 80 cm in width and 210 cm in height. It is also possible to build customized solutions having very large or very small passage sizes. The dimensions for single-leaf doors start from a width of 600 mm up to 2000 mm, and from a height of 500 mm up to 2900 mm.

The maximum overall dimensions instead refers to the total space required to install a sliding pocket door system. In width, this size is given by the sum of the passage size and the counterframe dimensions while in height it is given by the space from the finished floor level to the underside of the supporting architrave.

Types of frames for sliding pocket doors

Choosing the correct counterframe model is not difficult, however, certain key factors must be taken into account.
These include: the type of door, the opening and the construction material of the walls.

  • Regarding the type of door: whether the door is fitted with jambs or not (the so-called flush-with-wall doors). The jambs and architraves refer to all those elements that cover the walls around the door panel, actually called frame. In traditional doors, it normally protrudes from the door and the walls around the door panel. If instead there is no frame, we refer to modern doors without jambs and architraves flush with the wall. In the third case, when all jambs and architraves around the door panel are integrated and flush with the wall, we refer to traditional contemporary doors.
    Each of these solutions requires a specific counterframe.

  • Regarding the type of opening: sliding pocket doors can be suitable for different contexts and, though they are highly appreciated for their space-saving function, are an excellent solution to discretely separate rooms, walk-in wardrobes, storerooms and service rooms. Moreover, especially with the larger-size versions, they add a modern and design concept to the setting, transforming it into a wide open space. Special striking solutions can be combined with sliding pocket door solutions. Some examples include curved doors or telescopic doors, which allow to create an opening up to 4 metres wide. It is also possible to have folding doors or hybrid solutions, where half the door slides away into the wall and the other half is hinged and swings open. Each of these solutions requires the installation of a dedicated sliding pocket door systems

And there was light

If you think that having switches, lights and sockets on the same wall where the door slides is a problem, you’re wrong. ECLISSE has devised a specific frame for this purpose.

  • Regarding the construction material of the walls. ECLISSE has developed specific systems for both solid walls and stud walls. This section introduces the main differences between a frame for solid walls and and a counterframe for stud walls. A frame for solid wall is made up of a metal sheet layer and looks like a metal structure supporting the plaster mesh. On the other hand, the version for stud wall has an open structure, resembling a metal framework (U-shaped guides and C-shaped uprights), on which the plasterboard slabs are placed.

Frames for stud walls

In the case of stud walls, the frames have an open structure similar to a metal framework on which the actual plasterboard slabs will be installed.

The unassembled frame version (KIT) for stud wall has compact overall dimensions that facilitate transport and optimise the storage in warehouses (over 50 pieces fit into one square metre). Moreover, it allows to decide on-site which internal passage to use (58/83 mm) according to the finished wall thickness, since the counterframe can be enlarged during the installation phase. Thanks to the innovative interlocking assembly system, no screws or screwdrivers are required, making the frame assembly process easy and quick.

The open structure is 20% more resistant to lateral bending compared to equivalent products currently available on the market*.
The reinforced vertical bars, together with the horizontal bars, result in a far sturdier structure compared to frames made of a single 5/10 mm metal sheet, normally found in closed structures.

* Based on internal laboratory tests conducted on various equivalent counterframes.

12 horizontal reinforced bars

Made of galvanised metal sheet with 7/10 thickness and dovetail shaped to withstand.


Vertical reinforced bars

They are made from 12/10 galvanized steel with a double reinforcement fold for high resistance to bending.


Metal header

Improves resistance to any pressure coming from above.

Frames for solid walls

A frame, designed to be installed on solid walls, is foreseen with a closed structure. In this case a standard-size (800x2100 mm passage size) ECLISSE frame can weighs up to 40 kilograms.

Protruding knurled plaster mesh

The thick mesh (50x25 mm) and the knurling improve the plaster adhesion to the metal sheet. The protruding mesh joins the counterframe with the wall becoming an integral part of it.

Micro-ribbed filler plate

Embossing is a punching process that creates relief elements on a smooth metal sheet. They are made of 12/10 metal sheet with double reinforcement fold to guarantee high resistance to lateral pressure.

16 horizontal reinforced bars

They bestow considerable resistance and rigidity on the frame so that it can effectively counter the tension generated by the maturation of the plaster.
