What is a door rebate: features of rebated doors, advantages, how to choose

In the design of some door panels there is such an element as a narthex, but what is it? At its core, the door ledge is a kind of continuation of the door leaf, a thin strip that extends a short distance directly onto the door frame. Let's figure out the purpose for which this is done and what the features of such models are.

The rebate improves the characteristics of the door

What is a door rebate, quarter doors and rebated doors?

There are various designs of interior doors - panel type, arched, with double-glazed windows and many others.
But all design options can be divided into two types: with or without a vestibule. When choosing doors for interior spaces, you should have an idea about this feature, which we will consider in this article. So, what is a door vestibule ? This term refers to the design of the ends of the door leaf, in which part of it covers (covers) part of the door frame. Sketches will help you understand the definition, one of which shows a door with a vestibule, the other without it.

Very often the vestibule is called a “quarter”, since the thickness of the vestibule is equal to a quarter of the thickness of the door leaf. And since the milling cutter, making a rebate, cuts a rebate in the wood, another name was generated - doors with a rebate. Thus, a door with a quarter, a door with a rebate and a door with a rebate are three synonymous terms that mean one constructive solution, colloquially used in most cases in relation to wooden interior doors.

Wooden doors with rebate

Armored doors with a quarter

But the rebate technology is used not only in wooden doors - all metal-plastic doors are made with a quarter, in almost all armored doors you can find a rebate (of course, conditional) - it is on this that the sealing rubber is attached.

Which doors are better: with or without a rebate?

The inevitable question that arises after the definition: which door is better - with or without a “quarter”

. Let's start with the most important thing - the price. Obviously, an interior door with a rebate will cost more, since the manufacture of the latter requires large technological operations. Is it worth shelling out money for this? There is no definite answer - it all depends on the interior of the room and the tastes of the homeowner.

Interior doors with a rebate are considered a classic option, while doors without a “quarter” are considered more modern, in the “modern” style, so to speak. For this reason, it becomes clear that in rooms with classic furniture, doors without a rebate may look somewhat out of place. Classic doors may look even more inappropriate in modern interiors. The above lines reflect the generally accepted point of view, nothing more. And there is another point of view - stereotypes are created in order to destroy them. So it all depends on your taste and financial capabilities.

An important criterion determining the choice of interior doors is ease of use. In this regard, no particular differences can be found, with the exception of one rather important feature. A door without a rebate must be made of very high quality in terms of matching its geometric dimensions with the dimensions of the frame. Otherwise, different gaps between the door leaf and the frame can reduce the aesthetic effect to a minimum even in the most expensive doors. Agree, it's just ugly. The narthex closes the above-mentioned gaps, so even a door that is not entirely straight will look very decent.

Another feature of rebated doors is the hinges - their design is different from that of conventional doors: the axis is shifted to the side behind the rebate. Sketches will give you an understanding of how such loops work.

If you order ready-made interior doors, then the structure of the hinges is probably not of particular interest to you. If you are planning to install rebated doors yourself, then it may be worth finding the hinges first, buying one and checking how well it fits the doors. The issue of hinges is discussed in more detail in the article “Structure of hinges for interior doors.”

Door with a rebate: features of doors with a quarter

Choosing an interior door is a responsible task, because the door not only fulfills its intended purpose, but also decorates the room. When purchasing, you need to take into account not only the material and appearance of the product, but also the design features. When purchasing a door with or without a rebate, you should not rely only on your desires. When making such a decision, you need to know what a vestibule is, what it is intended for, and in what cases a door with it would be appropriate.

Features of rebated doors

An ordinary door is a leaf that fits completely into the door frame so that there is a gap of 3-4 millimeters between them. A door with a rebate has a protrusion along its entire perimeter at the end, which rests on the door frame when closing. Its thickness is one fourth of the thickness of the door leaf, so another name for the vestibule is a quarter. You can also hear the term “rebated doors,” because the milling cutter, when making a rebate, cuts a rebate in the door leaf.

Quarter doors have a number of features:

Interior doors with a rebate are classified as classic. They will fit into a room with the appropriate interior design style and furniture. A door without a rebate is considered a more modern style.
A door with a rebate can be made of different materials: wood, plastic, metal. Almost all plastic doors are made with a quarter. The same can be said about armored ones.
Another distinctive feature of a quarter door is its seal. The protruding strip is excellent for attaching a special rubber band, whereas sealing a regular door is very difficult.

It is interesting to note that some manufacturers produce quarter doors, in which only the vertical ends of the leaf have a hinged strip.

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.

Advantages and disadvantages of rebated doors

Rebated doors have a number of advantages over more modern options.

Noise insulation. Due to the fact that the strip fits tightly to the door frame, the absence of gaps is ensured and the sound insulation qualities of the door are improved. Sealing with a special tape will further help absorb noise.
Thermal insulation. Better heat retention is due to the same reasons as noise absorption.
Hiding defects during installation. A door without a rebate must be installed as accurately as possible so that the gaps on all sides are the same width. This requires certain skills. A door with a rebate is easier to install; the strip will hide all the shortcomings made during installation.
Aesthetics. A classic door with a rebate will highlight the interior of the room.

Speaking of disadvantages, it is worth noting the higher cost. This is explained by the fact that the manufacture of a door with a quarter requires greater technological costs compared to a regular one.

Hinges for interior doors with rebate

When choosing a door with a rebate, you need to take into account its design features, which are reflected in the type of hinges used. Conventional overhead fittings will not work here, since the strip must fit tightly onto the door frame. Therefore, for doors with a quarter, only two types of hinges are used:

Corner hinges are attached in the same way as simple straight ones. They differ in the mounting plate, which is bent at an angle of 90 degrees.

Screw-in hinges are twisted into the box and the canvas using pins. In this case, the fastening to the canvas is made obliquely, touching the vestibule.

For rebated doors, screw-in hinges are most often used. Moreover, their installation is carried out at the enterprise during the manufacture of the structure. That is, in the store you will have the opportunity to buy an already assembled door with a frame. Unlike regular doors, which can be fitted with a variety of hinges of your choice, quarter doors do not offer this option. Therefore, manufacturers often take on this task themselves, making the installation process easier.

Knowing what role the door ledge plays, it will be easier to make a choice. A well-chosen door will highlight the interior, placing all the necessary accents.

Features of the fittings used

Due to the design features of such doors, it is necessary to select special fittings. First of all, we are talking about loops. Since their axis moves slightly outside the vestibule, the following models would be appropriate here:

Corner card hinges - they look like corners attached to a hinge element; they are attached in the same way as simple straight hinges: one part is fixed on the edge of the door, and the second is screwed to the edge of the canvas and the inside of the vestibule.
Screw-in hinges are a good alternative to card hinges; they consist of two screw-in pins and a hinge, one part is screwed directly into the box between the rebate and the platbands, the second pin is inserted obliquely into the canvas, touching the rebate.

Screw-in and corner card hinges are well suited for rebated doors

Screw-in hinges are only suitable for durable materials that will not crack under such load.

If a door closer is used, special settings should be made for rebated doors. It must be taken into account that part of the leaf will touch the frame from the outside, so the movement of the door should be smoother at the end of closing.

Rebated doors are an excellent solution for the home, not only from a decorative point of view, but also in terms of useful functionality.

What are interior doors with a rebate?

The modern assortment of interior doors allows the consumer to choose a door design based on different considerations: for some, the aesthetic component is more important, for others, it is important to have increased strength characteristics, and for others, the most important thing is that as little extraneous sounds as possible penetrate through the installed doors.

Choosing interior doors with a rebate

But did you know that there is a type of door design that combines all of the above qualities? This device is called interior doors with a rebate. We will tell you in detail and clearly about how such doors differ from other subtypes, what features they have, how they are installed and what their advantages are.

How to attach the false strip

When choosing a new door, many people have a question - what is a false strip, why nail it, and what is the specific advantage of an opening decorated with strips. A flashing or rebate is a thin decorative strip made of wood material, with which you can hide all the gaps between the door and the frame. It is located in the area where the functioning part adjoins the pillars of the door structure.

This element is not considered mandatory, but it can provide an attractive and complete look to the entire installation. But if the design of interior doors is purely a matter of taste, then for the entrance such strips are necessary - they block access to cold air.

What is the fundamental difference between interior doors with a rebate?

A buyer who has little knowledge of door structures will not be able to distinguish a door with a rebate from a door product without it at first glance: visually they are not much different, they may be made of the same material, have the same locking device, etc. To notice the difference, you will need to take a good look at the design, and then you will notice that one part of the canvas protrudes slightly and, when closed, tightly overlaps one or three parts of the box (photo).

If we talk specifically about the design of the narthex, then the narthex of the door is a special thin strip of wood, the thickness of which is always equal to ¼ of the total thickness of the door leaf. Therefore, such interior structures are often also called quarter doors or rebated doors, but if you compare the door vestibule in the photo, it becomes clear that these are all different designations for the same design.

In the assortment of stores selling door products, you can also find a door with a double sash - in this case, the ends on the canvas will be located in two places of the structure at once - at the top and at the bottom (photo).

Features of the fittings used

Due to certain design features of doors with a rebate, it is necessary to select special fittings . First of all, you need special loops. The need for their use is due to the fact that in such door structures their axis moves slightly beyond the narthex. Therefore, it is appropriate to use the following models:

Corner card. They look like corners that are attached to the hinge element. They are fastened in the same way as from straight hinges. One part is fixed on the edge of the hole, and the second is screwed to the edge of the canvas and the inside of the vestibule.
Reversible - they are a good alternative for the former. Their design includes screw-in pins and hinges. The first part is screwed directly into the box between the vestibule and the platbands. The second pin is set obliquely to the canvas, slightly touching the rebate.

It is necessary to set different settings if a door closer . It is necessary to take into account the fact that part of the canvas will touch the box from the outside, so the movement of the structure at the end of closing should be smoother.

A few words about the advantages and disadvantages of products

A quarter door is a special design with an almost complete absence of cracks and gaps between the door leaf and the frame. It is the vestibule that makes it possible to achieve such an ideal fit, and therefore interior doors of this type have remained a relevant product in apartment design for several decades in a row.

The obvious advantages of interior doors with a rebate include:

High soundproofing qualities. A door leaf with a hinged strip allows you to achieve perfect tightness when closing, and therefore no extraneous noise will penetrate into the room. Doors with a quarter rebate are the optimal solution for children's rooms and work spaces - after all, in both cases, noise is a strong hindrance to the child's rest or normal work process.
Structures with a rebate ideally retain heat in the room; the protruding part of the canvas reliably insulates the living space from drafts and cold air. The pretend part of the product will perfectly protect against the spread of moisture, which is why doors of this type are often installed in kitchens and bathrooms (photo).

Additional sealing in the door ledges, which is especially important for use in cold or drafty rooms, helps to enhance the useful qualities of structures. A special rubber with a porous structure is used as a seal.

However, interior doors with a hinged strip also have disadvantages that you should learn about before purchasing and installing the product:

Designs of this type are somewhat more expensive in terms of price than other types of door products. This is due to the special manufacturing technology and the complexity of installation. By the way, it is best to entrust the installation of the product to professionals, because installing the product is quite difficult, and not everyone can independently install the structure in the interior space.
Products with a rebate look more massive than conventional doors and can visually conceal the volume of space, so their installation is preferable in rooms with sufficient square footage.
The fittings for such products are produced in a special screw-in design: they are installed on the end of the sash vertically and, when the lever is pressed, they are tightly connected to the frame of the structure. Screw-in hinges for doors with a rebate complicate the installation process of the product, but are absolutely invisible and allow you to adjust the opening process in three directions at once.

Useful purchasing tips

When choosing a design with a vestibule for your apartment, home or office, be sure to pay attention to the following design characteristics:

Visually evaluate the cover strip itself - it should be perfectly smooth, without the slightest defects or damage.
Pay attention to the seal. Its quality can easily be checked by trying to open and close the box - if during this process you hear a creaking or grinding sound, the product is not of good quality and you should refuse to purchase it.

The most common and popular type of door structure with a rebated element is swing doors. Products of this type can be single-leaf or double-leaf, solid or “glass-like”. Hinged doors with a rebate are often used in the interior of residential premises, as they have the most attractive appearance and are quite affordable.

What is the sash rebate size?

I ordered the installation of plastic windows, but they tell me that they will need a rebated sash size.
I'm wondering what this means? This is the first time I’ve encountered this. It is extremely necessary for the competent selection of fittings.

To determine it, use the calculation FFB=RB-(2·RPB)-(2·FL).

The concept (word) “rebate” implies the surface (from the inside) of the frame, or the sash itself along the perimeter.

The fold (its shape) can be beveled or straight, and this must be taken into account when taking dimensions.

And the size of the sash (the sash is an opening one, or the blind part of the window is attached to the frame) along the rebate is the size of that same window sash (see above what a sash is) to the same plane along the perimeter of the frame (see above what a rebate is).

Also keep in mind that the overall size of the window sash is larger than the rebate size of the sash.

The fold contains grooves for mounting accessories.

I ordered the installation of plastic windows, but they tell me that they will need a rebated sash size.

It is better to take all measurements by professionals; if you have a beveled rebate shape, then you need to take into account that the dimensions on the outside and outside will be different.

And in general, when ordering windows, the craftsmen do not burden users with professional terminology, but take all the necessary dimensions themselves, and this is free.

To make a window, you need to know the size of the window opening first.

sash rebate size. I'm wondering what this means?

The rebate size of the sash is a technical characteristic of the method of opening the window.

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.

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.

Types of porch

To install a plank with your own hands, you will need special adhesives, liquid nails and ordinary fasteners. Separately, the porch can be made in a furniture company. If the quarter is installed on a partition with two sashes, then it must extend beyond the sashes so that the gap closes tightly. The strip attached to the back of the door structure acts as a box, eliminating the gaps between the door leaves.

There are several types of vestibules by level:

with one;
with two;
with three levels.

Attention! The design can be conventional or equipped with insulating materials that increase insulating capabilities. It will be more difficult to install such doors without specialists, especially in the absence of knowledge and experience.

Levels
Externally, the doors look massive, so if the room is small, then it is better to give preference to other models of interior structures.
