What is a door strip, its main functions and types

• hiding unsightly cracks and gaps between the door leaf and the door frame;
• improved door sound insulation;
• reduction of heat loss;
• preventing drafts;
• protection from foreign odors and dust entering the room;
• hiding defects and shortcomings made during door installation;
• hiding the gap that formed when the hinges were worn out and the fabric was slightly skewed;
• aesthetics and additional decoration of the door.

The hinged strip is installed on an interior door quite simply and quickly.
It can be glued to the door leaf using special glue or liquid nails, or it can be nailed to the surface with nails. If the vestibule is installed on a double door, then the strip should protrude beyond the part of the door leaf that opens first to the exit. If the shutter strip is installed behind the non-working door leaf, it will close the gap between the door leaves and thus serve as a door frame.

Types of hinged strips for interior doors

There are many different types of hinge strips for interior doors.
There are many different types of hinge strips for interior doors: simple, flat, figured, multi-level, corner-shaped. They can also have a matte or glossy surface, any texture and any color shade.

At the same time, the rebates can be additionally equipped with a seal or a special regulator, which ensures a tighter connection of the canvas with the box. There are also anti-vandal door trims, which are characterized by increased thickness. The use of such strips reduces the risk of the door being broken open from the outside mechanically.

Slats have high environmental properties, since they are usually made of solid wood, chipboard or high-density MDF, veneered with valuable wood species. There are also fender strips of a more budget-friendly type - laminated with decorative film. A high-quality, correctly selected door strip will not only reliably perform its functions, but will also become an additional decorative element of the door structure.

Application of a shutter strip for an interior door

The main function of the door strip is to cover the gap that has formed between the door leaf and the frame or two swing door leaves. If the junction of the door leaf and the door frame does not form a gap, then there is no need for a cover strip. The door strip is very often used when reconstructing a wooden interior door, as well as after repairing the ceiling and walls of a room that require replacement or restoration of wooden cladding or wooden surfaces.

Old wooden cladding parts can deteriorate and dry out over time, leading to the formation of gaps and cracks. The use of a cover strip in this case allows you to close the resulting gaps and cracks and at the same time hide the imperfections of the old wooden surface.

The hinged strip is used not only for swinging interior doors, but is also widely used in sliding systems. The hinged strip in a sliding door allows you to carefully adjust the interface between the moving door and the wall, without leaving any noticeable flaws. The door strip should have the optimal width and match the color and texture of the door leaf and other structural elements of the interior door.

What is a pretend bar?

One of these little things will be the pretend bar.
A cover strip is an additional structural element, a small-sized decorative strip, which makes it possible to make joints and cracks on various products made of wood, MDF, and fiberboard invisible. In our case, let's take a closer look at the door trim. Typically, the door leaf fits into the door frame with a gap of 3-4 mm. The narthex rests on the door frame when the door is closed. The thickness of the narthex is usually a quarter of the thickness of the door leaf, which is why the narthex is sometimes called a quarter. The narthex creates an additional abutment area, which improves the quality of the doorway. Without a door strip, it is difficult to arrange a double-leaf doorway. It completely covers the gap between the door panels. Sash strips can be used in other door systems, including sliding door systems. The cover strip eliminates all, even very minor, flaws that may arise during installation; in addition, it improves the soundproofing, thermal conductivity and other qualities of the doors.

Fake slats are carefully selected to match the doors. The color, texture, and tone of the door strip must completely match the door.

False slats are made from both natural wood and chipboard and MDF, veneered or laminated.

The narthex is attached in two versions:

• from the outside of the door;
• from the inside.

The door strip is attached in such a way that it necessarily protrudes beyond the part of the door that will be opened first. The quarter can be attached to liquid nails, nailed with traditional nails, glued - it all depends on your capabilities and preferences.

The vestibule, at first glance, is an insignificant detail, but it has a lot of useful functions. One of which is sound insulation. On one side, the plank improves sound insulation. On the other hand, when using a strip, you can install additional sound-absorbing elements that are hidden under it. The flap also improves thermal insulation. When installing the strip, you can install additional rubber elements for sound and heat insulation. Well, and not the least purpose of the strip is to hide defects in the installation of doors. The vestibules can hide some flaws made during installation.

Classic double doors always have a rebate that serves as part of the interior.

Not every hinge fits a rebated door. Doors with a rebate are compatible with two types of hinges: screw-in and corner. Typically, rebated doors are equipped with screw-in hinges at the manufacturing stage.

We wish you to purchase decent doors with all the necessary accessories, install them correctly, using the maximum of additional and such comfortable elements. Having purchased a narthex, you can always adjust it to the dimensions of a specific door.

A door of a complete design solution with installed decorative elements will make your interior unique. A cozy and comfortable environment will always lift your mood and vitality.

What is a door rebate: design and installation features

Despite the fact that doors are equipped with various elements of fittings and decor, almost each of us at least approximately understands all of this. However, the rather simple question of what a door trim is and whether it is needed will certainly confuse many. But answering it and deciding whether it’s worth purchasing (manufacturing) a model with such a “part” is not at all difficult.

You can say this about the door ledge - a strip made of the same material as the leaf, due to which the width of the latter increases. Sometimes she is an extension of her.

And the meaning of attaching the vestibule to it becomes clear if we recall some of the features of the block. All its structural parts (frame, leaf) have the correct geometry (rectangle), otherwise the door cannot be closed by definition. Consequently, a small gap is formed between them. That's the whole point.

Any gap is a kind of “channel” for the entry of dust from outside, the penetration of extraneous noise and heat loss. It turns out that a door with a rebate provides better sealing of the opening without any additional measures. Of course, some technological operations for insulation and sound insulation are carried out depending on local specifics, but their list is definitely narrowing.

When closing a door with a rebate, the bar is completely superimposed on the side gap, thus blocking the natural circulation of air masses through it. At least, there is no need to additionally seal the block in this part. But that's not all. Even if we are talking about an opening connecting rooms, the false strip on the door is sometimes an additional decoration of the canvas.

Here, a lot determines the style of decoration of the room. For example, for “classics” and “country” such a design solution couldn’t come at a better time. Not a single specialist in this field disputes this fact. But for modern interiors (high-tech, art deco, kitsch, minimalism, and so on), a rebate on the door is hardly appropriate. Although this is a matter of taste, since the issue is quite controversial.

Many models are equipped with these strips, regardless of the base - plastic, metal, solid, paneled. And although they are somewhat more expensive, this is well worth the benefits. Some have been noted but bear repeating.

• Reduced heat loss and drafts.
• Improved sound insulation.
• Preventing dust and foreign odors from entering the room.
• Increased level of protection. This mainly concerns doors installed at the entrance. The narthex reliably covers the “tongue” (crossbars) of the lock, thereby making direct access to them difficult. Therefore, it is much more difficult to remove such a door from its hinges.
• Decorating the block. Small defects at the junction of the canvas and the box are reliably hidden from visual inspection. That is why the vestibule is often called the narthex.

These strips come in several designs. Manufacturers supply the market with simple and multi-level, flat and corner-shaped vestibules. Some of them have an adjuster, which allows for precise adjustment and ensures tighter pressing of the canvas to the box. Doors are also available in anti-vandal versions. In addition to everything else, they also have special porches - with increased thickness. This solution reduces the risk of breaking the door from the outside using hand tools or mechanically.

What you should know about narthexes

• If the door is equipped with a closer, and the bar is not flat, but in the shape of a corner, then the adjustment of the mechanism has a peculiarity. At the last stage of closing the door, its movement should be slowed down as much as possible. This will eliminate the risk of damage to the narthex if it definitely does not fall into the gap; for example, due to thermal deformation of the material.
• Fixing the strip on the canvas is done in two ways - by applying glue or using fasteners. When choosing a door model, it is worth understanding how repairable it is in this regard. In other words, will it be possible to replace a damaged plank yourself without a complete restoration?
• The porch is sometimes attached to the box, and not just to the canvas. Something to consider when purchasing.

Whether or not to install rebated doors in a house is a personal matter for the owner. But the advantages are obvious. In addition, if the hinges are sufficiently worn and the fabric is slightly skewed, the too noticeable gap will be reliably hidden. And if you show your imagination, then a model with a porch can fit into any, most unusual, diverse interior.

The difference between doors with and without rebate

Simple partitions differ from interior doors with a rebate in that they are made in the form of a straight panel without additional elements at the edges. When closed, the sash becomes flush with the wall and completely fits into the pocket. There is a gap between the end of the partition and the box along its entire length.

The door ledge is installed at the end of the leaf on the side opposite the hinges. You should pay attention to the fact that the bar should protrude enough to completely close the gap. The element only partially fits into the box, the rest of the part is adjacent to the chamber and isolates the room - this is the main advantage of the vestibule.

Advantages and disadvantages of products

The need to install a quarter remains a big question. The cost of the door increases due to this component. Therefore, you need to figure out whether such costs will be offset by increased functionality.

Appearance of rebated doors

So, let’s look at the main advantages of using a door strip:

• Increased insulation from noise and sounds. Since the gaps are reduced as much as possible and the density of the door cover increases, this becomes a serious barrier to the penetration of third-party sounds. Thanks to excellent tightness, the comfort of use improves, especially if the room is located in an area with increased noise.
• Thermal insulation. By creating a high degree of tightness, comprehensive protection is guaranteed against cold entering from outside and heat leaving the room. With the help of a quarter, you can get rid of drafts and maintain comfortable temperature conditions in the room. This eliminates the need to insulate the door.
• Small errors during installation of the door structure can cause gaps or deviations to appear between the door and the frame. These aspects together worsen the aesthetic performance of the door. With the help of a strip, these defects are successfully hidden.

Despite such tangible advantages, door shutters also have certain disadvantages, the essence of which should be taken into account before installation. First of all, this concerns the budget, since doors with a strip are more expensive compared to the same models without a quarter panel. In addition, the presence of this component introduces a number of restrictions on the selection of suitable loops.

Loops

Important information! A narthex is a part that increases the functionality of interior or entrance door devices. This is supposed to provide increased protection from noise and cold and impart aesthetic properties. The design of such products is more complex, and installation requires experience and knowledge.

DIY installation

Installing the bar does not take much time and effort. It can be performed by a novice master. The part can be attached using the following materials:

• glue;
• liquid Nails;
• metal nails.

If the rail is installed on a double-leaf interior partition, then it must protrude beyond the part of the sash that opens first to the exit. The strip installed on the back side of the non-working door leaf will act as a box, closing the gap between the leaves.

Application of the cover strip

The door strip looks like a protruding part that can be installed on the outside of the door leaf or on the inside of the door frame. When the door is closed, the shutter will close the gap between the leaf and the door frame. However, a cover strip is not always needed - when the junction of the door leaf and frame does not form a gap, then the need for a cover strip disappears.

Flashing may also be required when remodeling a wood door, as well as when renovating ceilings and walls that require replacement or restoration of wood surfaces and wood siding. Old wooden parts can dry out over time, and a false plank can hide not only the gaps that have formed, but also hide the imperfections of the old wooden surface.

Description of the porch

Not all craftsmen and users know what it is - a hinged strip for interior doors. This issue needs to be dealt with in more detail.

The element is mounted on the other side of the hinges, protruding exactly the amount of the gap. A door with a rebate has a protrusion at the ends, which comes into contact with the door frame at the moment of closing. Its thickness is not chosen arbitrarily, but according to its shape: 25% of the door thickness, which is why the element is popularly called a “quarter”.

Important! The flashing looks like a decorative strip made of the same material as the door leaf. Interior doors are equipped with a vestibule in openings with double doors.

The definition of “rebated door” wanders among buyers. It arose due to the nuances of production, because to make the narthex, the contour of the fold is cut out in the canvas using a milling cutter. The narthex is a continuation of the door leaf, which is in contact with parts of the frame.

Types of porch

To install the plank yourself, you need glue, metal or liquid nails. The insert porch can be ordered from a furniture company. If the flashing is mounted on a double-leaf partition, then it should protrude into the sash area to close the gap. The strip, attached to the back side of the leaf, performs the tasks of the box, hiding the gaps between the sashes.

Article on the topic: The plastic door has settled, what to do

The vestibules are made in several types:

• single-level;
• two-level;
• three-level.

It can have a standard design or additional insulation that increases sound and heat insulation. Installing such a door without a specialist is more difficult, especially if you lack the knowledge and skills. Visually, the structure looks massive, so for modest-sized rooms it is better to choose a different interior door.

Rebated door designs

Installation of such doors requires the selection of special fittings. When choosing, you need to pay attention to the loops, which are:

1. Screw-in. The structural elements are a hinge and two pins.
2. Corner card. It has the appearance of a corner, the model is mounted using the traditional method, like ordinary straight hinges. One part is screwed to the box, and the second to the canvas and the inner area of ​​the vestibule.
3. Hidden. The main mechanism is located in a metal case, which is hidden in the end area of ​​the door. The products are mounted using a milling saw; expensive models are supplemented with a door closer. A positive quality of such hinges is their concealability when closed.

Screw-in hinges are installed in durable doors, since there is a chance of compromising the integrity of the structure. When using a closer, additional adjustments must be made. It is important to consider that the canvas will touch the box from the outside, so at the final stage of closing the movement should be smooth.

Screw-in hinges are installed at the factory, which means you can order a design with ready-made fittings in the store. This fact simplifies the installation process, although for some buyers who want to maintain a single style of fittings, this is a serious drawback.

Features of fittings

An additional feature of designs with a rebate is that they are not compatible with all hinges. The design of special hinges differs from conventional doors, since in this case the axis moves in the direction of the bar. If you understand how these fittings work, you can always make the right choice.

Accessories

Among the available elements are:

• card loops like corners - fasteners that bend at right angles; when installed, one part is fixed at the edge of the hole, and the second is attached directly to the canvas;
• screw-in - their design contains hinged components on which pins are attached; they are attached to the canvas along an oblique path;
• hidden - a more complex design with hinges hidden under a metal body; there is also a screw that connects the moving parts.

The insertion of loops must be done as carefully as possible; a router is used for this. Hidden hinges are sometimes equipped with a closer, which also facilitates the operation of the structure.

Differences between doors with and without rebate

The standard door leaf is placed in the door frame with a gap of several millimeters. The narthex closes the gaps, which provides additional heat and sound insulation.

Due to their design, doors with a “quarter” have several features:

1. They belong to the classics. They are suitable for rooms with a characteristic interior. Models without a rebate are classified as modern style.
2. Main materials: plastic, metal, wood, solid MDF. Armored and metal-plastic doors in 90% of cases are made with a strip.
3. Additional insulation and protection against heat loss is provided by a seal in the rebates, which is a special rubber band.

There are models on sale in which the cover strip is located only at the vertical ends. Such structures do not provide complete tightness, although they are equipped with a seal.

Installation of interior doors

Beautiful and convenient interior doors provide comfort and coziness, allowing you to decorate the interior of the premises in the chosen style. But the final result depends not only on the correct choice of doors, but also on the quality of their installation. Door installation has many subtleties and nuances known only to specialists. It is very difficult to do this work yourself, without the experience and necessary tools.

Professional installation of interior doors involves performing many operations, including:

• dismantling the old door and door frame;
• installation of a new door frame;
• insertion of door hinges;
• inserting a lock into the door leaf;
• hanging the door;
• installation of accessories (if necessary);
• installation of platbands.
