More and more manufacturers of interior doors are producing telescopic frames or, as they are also called, Euroblocks, trying to facilitate the installation process in the future. It is also worth noting that such a block looks more civilized compared to a regular one due to the almost complete absence of joints. What is a telescopic interior door frame and how to use it correctly - read on.
What does a telescopic box consist of?
The telescopic door frame consists of slats (two vertical and one or two horizontal) with grooves. The sizes of such elements may vary. The set includes extensions and telescopic trims. The assembly is carried out according to the type of constructor. Each model is supplied with instructions by the manufacturer.
What it is
The term "telescopic" is usually applied to objects consisting of several parts that extend from each other. A door frame of this type, in accordance with the definition, is assembled from several slats, only they do not slide out from each other, but snap into place using a system of grooves, forming a single whole. Thanks to this connection, the parts of the block are easily adjusted, and the end result gives a perfect rectangular shape. Today, two types of telescopic block are produced:
- The design of the box and platband as a single whole;
- Two separate components - a box and a platband, connected by grooves.
Telescopic door frame: pros and cons
Before you order and assemble a telescopic door frame, you need to understand the pros and cons of using this type of frame. This will help you decide whether to choose such a product.
The telescopic box has the following advantages:
- Simple and quick dismantling. What is important for those who often carry out repairs and re-glue wallpaper.
- Possibility of repeated removal and installation.
- Easy installation. The design consists of protrusions and recesses. You can assemble and install the door frame with your own hands. This allows you to save on the services of a specialist.
- Aesthetic appearance. A door frame without nails looks neater.
- The ability to bridge gaps of any size between the wall of the doorway and the door.
- Saving money. The entire doorway is well hidden by the Euroblock. Therefore, you don’t have to spend money on finishing it.
- Long service life.
- Versatility. The telescopic door frame is suitable for different types of interior doors (hinged, accordion, sliding, compartment, etc.).
Among the disadvantages of the telescopic box, one can highlight only the price. The cost of such structures is higher than conventional analogues.
Material of manufacture
The telescopic frame of the interior door is made of solid wood, glued sawdust (MDF) or metal. The bulk of components are sold by linear meters. Therefore, it is recommended to purchase both the box and the canvas in the same place or from the same manufacturer.
There are two options for choosing a color:
- Classical. The block and the canvas are made in the same tone and texture;
- Contrasting. The euroframe and the door are painted in contrasting shades, for example, a light door in a dark frame.
The latter option is increasingly found in the latest issues of interior magazines; it looks quite stylish and fresh.
Selection of telescopic door frame by dimensions
For successful installation of interior doors, it is important to determine the size of the Euroblock. It is necessary to correctly calculate the width, thickness and height of this structure. These parameters depend on the size of the doorway. There should be a gap of 3-3.5 cm between the wall of the opening and the door frame. The planks should completely cover the thickness of the wall.
What is it for?
In houses with thick interior walls, it is quite problematic to aesthetically design the doorway, since additional finishing of the slopes is required. Most often, such passages are decorated with platbands on one side, and painted, covered with wallpaper or covered with plastic or MDF panels on the other.
If the width of the slope is small, then you can install an additional strip and attach the second set of platbands to it. But here comes the difficulty. The additional board is available in standard sizes (from 100 to 250 mm) and does not always correspond to the thickness of the wall.
In this case, you will have to cut along the extension, which requires precision, the presence of special equipment (a jigsaw) and the skills to use it. In the absence of the latter, there is a possibility of damaging the board, which entails the purchase of a new one (accordingly, additional costs) or the loss of the decorative properties of the door block.
This process can be facilitated by installing a telescopic box with the function of adjusting the expansion strip (extension), which allows you to decorate the opening on both sides with platbands.
How to assemble a telescopic door frame
When installing a door, inexperienced home craftsmen may have a question about how to assemble a telescopic door frame with their own hands. The work is not difficult. The main thing is to adhere to the algorithm of actions and some tips.
Here's how to assemble a telescopic box:
- Trim the frame elements to fit the doorway.
- Attach the top bar to the ends of the vertical elements and make cuts.
- Fix the posts and the narthex.
- Insert the assembled frame into the door passage. Secure with wedges and level.
- Secure the box with anchors.
- Install telescopic trims.
How to install a telescopic door frame can be found in the instructions. It is supplied by the manufacturer with the model kit. It describes in detail the entire installation process.
Correct installation
The entire installation process is simple and quick. The presence of a special tool will allow you to set the required box size even for those who do not have experience in construction work. It is important to understand the design features and follow a clear sequence when assembling it. It is necessary to select the size and shape of the frame in advance.
Initial parts for installation:
List of special material and tools:
The assembly process will depend on the type of trim used and the width of the box. For example, for openings of non-standard width, platbands are used that contain an additional strip - it can be hidden.
The process of installing platbands is that they are pushed into the corresponding grooves. They need to be strengthened as accurately as possible. They are fixed firmly, but in some cases craftsmen additionally use liquid nails. It should be noted that such an addition makes the structure one-piece. The result of the work is that each side of the box should be one plane with good platbands and extensions.

Installation of interior doors with telescopic frame
You can install a door block with a telescopic frame in a room yourself. The gaps between the frame inserted into the passage and the wall are filled with foam. Wait a day or more for the sealant to harden. After this, the excess parts of the polyurethane foam are cut off with a knife. The hinges are attached to the box. The door leaf is hung on them. Next, the fittings (handles, locks) are put in place. The work of the canvas is checked.
Installation
The main component of the box and the additional strip are assembled separately; they are connected at the moment when the canvas is installed. The frame is placed first in the opening and fixed in the same way as a conventional block for interior doors is installed. After the canvas with hinges and fittings has been hung on the frame, its operation and the presence of the necessary gaps have been checked, you can begin the final installation of doors with a telescopic frame and blowing in the foam. As soon as the foam has dried and its excess has been cut off, it’s time to install the additional strip and adjust its width.
But it is worth noting that in blocks with an extension and a platband, made of a single design, it will not be possible to blow out the foam after installation. Therefore, first the eurobox is installed, the canvas is hung, the foam is blown in, and only then the adjustable trim is installed.
Manufacturers
Below is a list of the most popular manufacturers of telescopic doors that can be purchased in the Russian Federation:
- Profile Doors.
- "Leroy Merlin".
- TORMAX.
- Dorma.
Different manufacturers package their models differently. You need to check in advance what comes with them in the package (platbands, accessories, fittings).
Experts predict that telescopic doors will soon gain popularity in construction. But it is worth remembering that such a mechanism needs to be looked after so that it lasts as long as possible.
Frame dimensions and shape
To determine the geometric parameters of the door frame, two important points should be taken into account:
- Dimensions of the door leaf for which this frame is made.
- The purpose of the door block, that is, in which room the structure is planned to be installed.
For example, if interior doors with a frame are installed in a steam room, special requirements are imposed on such structures. These doors should not let out warm air and allow cold air into the room.
In the case when you need to create a reliable barrier that prevents the leakage of warm air, to make a door frame you will need four bars, which can be assembled using a hidden method. After connecting the beams, a closed rectangular frame is formed: the frame in this case will be represented by an upper cross member and a threshold connected to each other by vertical elements. A three-millimeter gap must be provided between the sash and the frame: failure to comply with this requirement will lead to problems associated with the movement of the canvas.
Which molding to choose: telescopic or simple?
Moldings are an addition to the door leaf - for fastening the door in the opening and framing the opening itself. Door frames are door frames, platinum strips and additional elements necessary for installing the door leaf in the opening. Door factories produce both universal (regular) and telescopic frames for decorating door openings.
The advantage of telescopic molding is, of course, ease of installation. Most installers prefer to work with telescopic platbands and boxes, because the telescopic box has grooves (grooves) in the boxes and an extension, and the platband has a so-called spout, thanks to which this structure is mounted. During installation, the installer should not resort to nailing.
The disadvantages of telescopic guides are, of course, the cost of this design. Telescopic moldings are more expensive than usual, but at the same time they allow all the elements of the door structure to be neatly joined together.
Advantages of such a system
Telescopic strips have a number of advantages over conventional ones: • The use of “hidden” fasteners allows you to assemble a door block without the use of traditional fasteners such as nails, screws and glue. • Allows the installation of internal frame doors in the opening with a deviation along the vertical axis. • Provides a more attractive door unit appearance due to the absence of adhesive residue and visible nail caps or screws. • Thanks to its special design, this system is able to hide all possible defects around the box with different wall thicknesses. • Provides the opportunity to significantly reduce costs when finishing doors. • Professionally completed installation showcases a unique, exclusive design due to the visual integrity of the telescopic molding system. • Sound insulation can be easily installed in this structure.
• Allows you to identify interior doors with a rather sophisticated design, regardless of the thickness of the walls. • The telescopic forming system can be easily adapted to different hole depths, even for sizes up to 200 mm. • Installation of a special frame into the frame ensures quiet and tight closing of the door. • Allows you to significantly simplify the selection and installation of interior doors.
With so many advantages, telescopic molding has one “minus”. To purchase it you need to spend a little more money compared to the usual one. But the significant reduction in costs and time for its installation more than pays off.
Features of its use
The desire of interior door manufacturers to simplify the installation process has led to the creation of telescopic molded products. This is especially true for holes with non-standard wall thickness. This system makes it possible to minimize the cost of installing a door block. In addition, they managed to enhance their visual aesthetics.
Types of platbands
Based on the installation features, there are overhead and telescopic types of platbands.
Example of a telescopic type box
Modern designs equipped with telescopic platbands have a characteristic protrusion installed in a slot in the frame. This installation method is especially recommended when the box is tilted relative to the plane of the wall. Irregularities will be effectively hidden by telescopic platbands. Fixing with liquid nails will help preserve the appearance.
Installation of platbands does not require strict adherence to the sequence of installation stages of the entire frame. All that is required is to install the projections perpendicular to the platband into the grooves located on the box. The adjustment is made by simply pulling out the groove, and the joint is hidden in any wall, regardless of its thickness.
Design Feature
The box for installing telescopic doors of interior type is provided with special grooves required for installing the extension and trim without the use of additional fasteners .

Thanks to these grooves, there is no need for nails when fixing the platbands. For telescopic extensions, it is required that the wall width be greater than 14.0 cm. Installation of extensions with a thickness of 5-40 mm is allowed. Thanks to such additions, an opening of any thickness is suitable for installing doors.
For installation, most often, ready-made box kits are used, so during installation the time and effort required will be minimal.
