Sliding doors

Smoother and larger environments with sliding doors

As an alternative to the classic swing doors, the sliding doors for interiors, they are a particularly effective solution in small apartments but also for a more modern and fluid vision of the use of domestic spaces. This opening system has gradually acquired an aesthetic identity, customizable thanks to a wide range of finishes and materials.

Interior sliding doors have the great advantage of creating continuity between the rooms, allowing greater use and also natural lighting between one room and another.

Furthermore, while a hinged door implies a limitation in the distribution of space and therefore in the furniture, the choice of installing sliding doors with internal track allows greater creativity. In addition to practical advantages, sliding doors are a decorative element, for which the choice of the material is fundamental. Wood, plexiglass and glass are the most used materials to make frames of this type.

Types of sliding doors

The sliding doors they can be of two types:

  1. sliding door external wall
  2. sliding door retractable

In the first case the door opens by sliding along the wall, in the second case the door opens inside the wall using a special system called subframe. The counter frame of a concealed sliding door is made up of a metal cassamatta or box that allows the door to slide inside.

Both solutions solve a space problem but the retractable one, compared to the external wall solution, also allows you to free the sliding wall, providing more furnishing possibilities.

How the counter frame for pocket doors works

The subframe of a concealed sliding door, also called a false frame, false jamb or cassamatta, is a metal structure that allows the sliding door to disappear inside a wall (plastered or plasterboard).

The subframe consists of one inner case to the wall, by a sliding system (binary), placed in the upper part, which allows the door to slide inside the wall and from a vertical upright stop that receives the door when closing.

Sliding door counter frame
A quality subframe must meet certain reliability and durability requirements:

  • Robustness: the counterframe must be as strong as the wall and its maintenance must not damage the wall.
  • Fluidity and lightness: carriages and track must allow a smooth and light movement of the door and must be easy to replace in case of damage.
  • Guarantee of a sliding seat of the door without bending of the subframe sheet.
  • Don’t make cracks: the counterframe, being an integral part of the wall, must not lead to alterations of the wall.
  • Ease of installation e maintenance: the easy-to-install counterframe guarantees and protects the product over time, making maintenance or installation of subsequent accessories possible, without affecting the wall structure.

I controtelai per ECLISSE sliding doors present the extractable track, to ensure the possible replacement of mechanisms subject to wear, the application of accessories and the adjustment of the internal door stop. They also come with alignment bar in galvanized sheet metal, which facilitates installation, allowing the subframe to be aligned with the upright.

How to choose a correct counter frame for sliding casket doors

The choice of the correct model of subframe must take into account some factors such as:

  • The door typology, that is the frame around the door panel: with jambs, without jambs (flush with the wall). Classic doors have the frame protruding from the door; modern doors have no frame; the contemporary classic doors, on the other hand, have all the elements external to the door panel flush with the wall.
    For each of these solutions, a specific subframe must be adopted.
  • The type of opening: door curve or doors telescopic with which you can have an opening up to 4 meters wide, doors to book, or solutions hybrid where half of the door panel opens hinged, while the other half disappears. For each of these it is necessary to install a dedicated subframe.
  • The construction material of the wall. ECLISSE has developed specific counterframes for both plaster walls than for walls in drywall.

Choice of subframe for sliding doors
The counter frame for casket doors on plastered walls has a full structure, which of standard dimensions (80×210 cm) can weigh over 40 kg.

The counter frame for plasterboard walls, on the other hand, has a open structure, similar to the metal frame where the plasterboard panels will be placed. The open structure is able to resist lateral flexion, more than 20% more than other equivalent structures on the market today.

The construction material of the door. There are no particular constraints in the finishes and materials of the disappearing sliding doors and even less in the dimensions. You can choose between wooden sliding doors, glass doors, or mixed solutions that combine wood and glass or aluminum and glass.

Calculate the dimensions of a sliding door

To correctly calculate the size of a pocket sliding door you need to be clear about the difference between door hole The passing light e maximum footprint. The door hole refers to the actual dimensions in height and width between the jambs (if present) and the height of the finished floor.

A standard sliding door has the same measurements as a corresponding hinged door, usually the width is equal to 70-80 cm and the height equal to 210 cm. Customized creations are also possible, the single door dimensions start from 60 cm up to 200 cm in width, and from 50 cm up to 290 cm in height.

Calculate the dimensions of a sliding door counter frame
Per maximum footprint, on the other hand, we mean the total measurement necessary to install a counter frame for retractable sliding doors, which in width is given by the sum of the passage light to the measurement of the counter frame inside the wall.

The height, on the other hand, is given by the measurements from the height of the finished floor to under the supporting architrave.

The firm ECLISSE provides the online configurator Search for Easy ECLISSE, which helps to identify the most suitable counter frame, for sliding doors or hinged doors flush with the wall, with a few simple clicks.

Prices for retractable sliding doors and tax incentives

The cost of a sliding door is determined by the different components and installation costs.

Of course, a sliding door with an external track has a lower cost than a retractable sliding door as there is no recessed counter frame. Typically the price starts from a minimum of € 600 to go up.

In the case of renovations you can benefit from the tax deduction of 50% IRPEF, which is applied for interventions that involve the modification of the door hole. The deduction is valid for all the supply and installation work necessary for the transformation of the door hole for the hinged door and for the adaptation for the installation of the subframe, also including the costs for the demolition of the wall portion of the sliding system.

Models of interior sliding doors, which ones to choose

EclisseThe company ECLISSE since 1989 produces counter frames for retractable sliding doors, which allow the door to slide and disappear inside the wall.

Continuous research has led to the development of specific sliding door frames for any construction material and exclusive patents such as LUCE, an idea that has made it possible to have switches and light points close to the hole in the sliding door.
