What are extensions for interior doors and how to install them correctly

The door structure plays a significant role in the interior. This is the entrance to the room, which sets the tone for the rest of the space. It is for this reason that it must not only be functional and reliable, but also have a beautiful appearance. Not only the main fabric and fittings are responsible for aesthetics, but also the additions to the interior door - what they are, we present photos in our article.

Why are the products needed?

These are horizontal and vertical strips with a special shape, which are classified as finishing building materials and serve to mask visual defects in the entrance group. The panel is installed between the platband and the box. It does not interfere with the opening and closing process.

There is a second reason, the main one, why installation of extensions is necessary. Manufacturers mainly complete their collection with standard models according to the width of the trim and main elements. They adapt to developers of apartment buildings, GOST standards and other regulatory documents. On average, the wall thickness does not exceed 7-8 cm.

But in the case of old buildings, as well as private houses and country cottages, there is a possibility that this parameter does not match; it is often a couple of centimeters less or more. In such cases, the voids are filled with plasterboard and a large layer of plaster. But this is quite expensive and, at the same time, not aesthetically pleasing. In addition, it takes a lot of time from the installer. It is in such situations that it is much more expedient to establish additional fees.

The standard set consists of three strips - two vertical and one horizontal. The first two will be installed at the edges of the doorway, and the second at the top. In this regard, their length will correspond to the platband, and their width will correspond to the distance that needs to be “reached” - this is where the word came from, by the way.

Trim material can usually be purchased at the store where your door was sold. There they select the optimal sizes, and most importantly, the color scheme. Most finishes have a standard texture and color, so you can purchase additional panels elsewhere. Well, if you have a working tool, free time and golden hands, then you can make the plates yourself.

Types of paintings

The main thing when choosing is to take into account the convenience and capacity in the room, that is, the functionality of the door and its combination with the bedroom.

There are several design options:

Swing door. This is the most popular door model because it saves space if its location is well chosen. Such doors can be made of any material, which helps control the sound insulation in the room. There are solid and glazed ones, with and without a threshold.

Double-leaf swing. This type has similar characteristics to a regular swing door, but requires a slightly larger opening.

Sliding. It is a wonderful design element and very easy to use. With its help, you can increase the area, especially if it concerns small-sized apartments. However, such doors are more expensive than swing doors and have a low degree of sound insulation.

Foldable. The book model is also very beneficial in terms of space saving. It makes it possible to vary the width of the opening and not go beyond it.

A folding door allows for a ton of design options and is very easy to install. However, this model is quite fragile and, if used carelessly, wears out quickly, and jamming and jamming may also occur. It is worth noting that such doors have poor sound insulation systems.

Reasons for installing planks

The main reason is purely aesthetic - to make the door structure ideal, complete, without hollow space. In addition, this allows you to protect the corners and make them less traumatic for children. In short, extensions are needed where the walls at the opening site are too wide.

It should be noted that if there were distortions, which usually form over time, then the panels will not correct the problem; you will have to first align the structure, and only then deal with the aesthetic issue.

So, to fully understand the situation, let's give an example from life. In an old private house we have very strong load-bearing walls. They have a width of 190 millimeters. And this despite the fact that the platband can cover a maximum of 80 mm. The remaining 11 centimeters need to be covered with additional strips.

This method is relatively innovative, but it is developing so rapidly that almost all stores offer such a part during installation. In particular, the company luxfold.ru offers a wide range of doors along with extensions that are ideal in color and texture.

The second option when panels are needed is when you need to widen the doorway. This is how you close the free space.

The advantages of this type of finishing include:

• The installation speed increases; installation is even possible on your own.
• When using wet wallpaper on walls or when plastering, there is no need to “climb” onto the wooden panel, as this has a very negative effect on it.
• Additional elements lead to the greatest stability of the entire structure.
• Great appearance.

Sliding or compartment doors to the bedroom

A popular option for rooms with small space. They are one or two canvases that are located on guides.

When opened, the canvas moves to the side and either connects with the second one or goes into the wall opening.

The variety of products is numerous. The first thing to note is the dimensions. In terms of width, you should choose from a wide variety - from 50 mm to 56 cm. And in length, almost all are standard - 2.1 m or 2.2 m. But if you have non-standard doors in height, you can order a longer one or make it shorter with your own hands . Width is the last important parameter, which is 10 mm.

We recommend choosing a panel based on the material that matches the door leaf. We will talk about this in more detail below. It is important that the building material is chosen correctly, as well as the texture and color.

Classification. What does the accessory look like for different types of interior doors:

• Regular.

They look like standard MDF planks with a top coating. They are usually laminated and covered with veneer on top. Externally, they differ only in color and size, but the style and dimensions are the same. They have grooves along the edges to aid installation.

• Telescopic.

The second name is typesetting. They are designed to “gain” extra centimeters, that is, to widen the doorway. Externally, they look like a carriage rail, that is, there is a ridge on one edge and a groove on the other, so you can mount the products without nails or other hardware, but only with the use of glue. They have a higher cost, but also collect more positive reviews.

• Combined.

This is a kit that combines both the platband and the regular extension, so they look very laconic, always match in color and are a ready-to-install corner. They are best suited for doorways with deep recesses - products are installed there well. Their peculiarity is that they are not suitable for very large walls, but are intended only to increase the opening by 2-5 cm.

What is the door for in the bedroom?

There are several reasons why an interior door to the bedroom is a necessary measure.

First of all, your vacation becomes more comfortable, even if there are a lot of people in the house or apartment. Household members, just as they need to, continue to actively go about their business, and no one will stop you from resting and getting a good night’s sleep.

The second reason for installing such equipment is the soundproofing function. While you sleep, if there is a door, you will not be able to be disturbed by loud sounds coming from the kitchen, bathroom, nursery or any other room.

Another reason is the need for romance for a young married couple. With such a protective measure in place, no one will interfere with the young, even if they do not live alone.

A correctly selected door does not allow light to penetrate, which can come from any source. For example, when family members return home late or leave early for errands, the lights turn on in the hallway, living room and other rooms.

To ensure that sleep is not interrupted as a result of this, dark doors to the bedroom are the most convenient option.

Materials

Various raw materials are used in production. Each product has pros and cons and different costs. They should be selected based on what type of door. The better the style, color and texture match. Below we suggest what types there are:

• Solid wood from different types of wood. This is an expensive material that is installed in luxury premises. The advantages are a high aesthetic appearance and a long service life. In addition, natural wood has health benefits. Ash, beech, oak and coniferous species are used.
• MDF. The advantage is that it is used most often when creating interior cladding. In this regard, it is most in demand. A number of other advantages: light weight; resistance to external damage (temperature changes, chemical detergents, shocks); ease of installation. Manufacturing method: pressing from fine-fiber wood and plastic material coated with laminated film or natural veneer.
• PVC. Simply put, it is plastic, like, for example, plastic windows. Sometimes PVC is also used for interior doors. Some users combine such extensions with MDF trim. This option is budget friendly. The panels are lightweight, easy to install, and do not require additional maintenance. They are very often used for entrance structures.
• Laminate. The base is wood fiber board, which has high strength. In addition to reliability, wear resistance can be noted.

Let's compare the qualities:

Choosing the right door frame: what is it, photo

The most important thing to pay attention to is how compatible the materials are with the door in terms of color and texture. Ideally, they should be made from the same type of raw material. We recommend purchasing the entrance interior structure together with additional plates at the same time, because this guarantees a complete match, as well as ease of installation. You can place an order in the vufold online store. The website offers a wide range of quality products at affordable prices. High quality, stylish appearance, quick installation are some of the few positive qualities of the company.

Additional rules for selection:

• A perfectly flat surface without defects: there should be no pimples, cracks or other externally unsightly elements. Each microcrack can eventually lead to a split.
• Make sure there are fastening parts (grooves and tongues) if you choose the telescopic type. The connectors must match each other as well as the factory doors. We recommend purchasing this type of extension together with the entire door structure.
• Look at the sizes. It is better to take completely suitable elements than to cut something yourself, since an unsightly unprocessed cut will be noticeable in some places. In addition, cutting will take additional time. What if the cut is not made correctly from the start?
• Pay attention to value for money. Don't just look for low cost. It is better to order products from trusted manufacturers who have many positive reviews of their work.

Various installation options

Installation, as well as choice, depends on the door frame itself. If there is a groove in the end part, then you will need to insert one edge of the additional panel into it so as not to catch and damage the box itself. For tight installation, strong adhesive is used. It is very important that it does not start to leave the designated place, leak out and stain the canvas. Sometimes you even have to use polyurethane foam, but only in cases where there is a large hollow space between the paneling and the wall itself.

If this built-in groove is not there, then you will have to make it yourself. To do this, use a milling machine. The main thing is to maintain a straight line.

The peculiarity is that despite the various methods, installation is quite simple even for yourself.

We only note that the element must be installed as level as possible, because there will be a platband on top. It may squint due to unevenness.

Do you need extras?

We think it would be logical to start with the simplest. Do I need to use extensions during work? Many people don't even know what it is. The board for interior doors is a special board, the width of which is at least 5 cm . It usually reaches 215 cm in length. The need for such planks may arise for the owner of an apartment if, in terms of width, the door frame turns out to be smaller than the thickness of the wall in which the door structure is installed. It must be said that the installation of the extension is carried out directly in the frame of the interior doors.

How to install

Let's give an example of installation on the classic version without special ends, grooves and other elements. When purchasing planks, you should remember that an average of 2.5 pieces are needed per door. If the dimensions exceed the necessary ones, you will have to use improvised tools. Any one that copes with its purpose and leaves fairly smooth edges will be useful. By the way, you can use grinding to process joints. So, let's go through the main stages.

We take measurements and make blanks

The first point, that is, measurements, can be done even before the material is ordered. If you use the service of a company, the measurer usually works for free, he has professional tools and skill. When installing it yourself, you should take a tape measure and walk with it on all sides. The main thing is not to reduce the result, since you can always cut it down, but you can’t increase it.

We recommend measuring the width (depth of the doorway) at two or three points on one side, since there may be minor or, on the contrary, quite significant curvatures. To do this, you need to insert the measuring tape all the way into the groove (if there is one) or attach it to the edge, and then add 1-2 cm to the future cut, and keep the other end at the end of the wall.

Next we make the blanks. Everything is simple here. Using the measured parameters, we measure the distances, and then use a regular pencil or a sharp knife to make marks/notches. Then, using a tool, we cut off the remainder.

We collect

First, prepare an incomplete box on the floor. That is, you need to put all the elements on the surface, using a carpenter's square, draw lines on the top crossbar where the structure will be assembled. Make several holes there. Then the screws will be screwed into it. Please note that if there is an uneven (sawed-off) edge, then the straight side should be placed side by side.

We assemble the letter “G” and insert the grooves (for fitting) into the door. Then we apply the third die and screw it on. Here we have a finished “P”.

Installation in a door frame

We look at the prepared opening. If there is foam inside, you should carefully cut it along the contour to easily place the decorative panel. Now we carefully insert our structure into the grooves. In this case, you first need to lean the top, then both sides. When installing, gently tap the wood with your palm. Now you need to achieve perfect evenness (we measure this indicator). Using mounting tape, which does not leave marks, we attach the extensions to the box. If there is space left between them and the walls, then it should be closed for tightness. The ideal option is to do this using special wedges. But if they are not there, then use pieces of foam.

Fastening the additional box

When all the parameters have been aligned using a level or level and wedges, you can, without removing the mounting tape yet, proceed to filling the openings with foam. Before starting the procedure, it may be worth moistening the surfaces - this information can be read on the bottle. You need to foam gradually - one layer at a time. When the material has hardened, you can get rid of the “tacks”. Now you can install the platbands - they will hide small defects and mistakes, but do not count too much on this, since they may stand crooked if errors were made in the calculations.

How to attach the product to the box if it is thicker than the selected quarter

In such a situation, you should do this:

1. drill holes obliquely;
2. use self-tapping screws instead of glue and foam;
3. Cover the metal caps with caps - be sure to choose them of the same shade.

You can also use plasterboard hangers, but this is much more complicated and requires the work of craftsmen.

In the article we talked about additional strips (extensions) for interior doors with photos - what they are, how to work with them and why they are needed. The advantages of the interior depend mainly on the little things, so you shouldn’t neglect them if you want to receive admiring assessments of your efforts.

What is a supplement and why is it needed?

Many doors produced by factories are designed for standard city apartments. Installation difficulties usually arise in old buildings or country houses. The thickness of the walls in these rooms may differ from the standard one, which is usually 7-8 cm. The places in the opening that remain unblocked by the door frame are often finished with plastic, plasterboard or plaster. However, a much more convenient way out of the situation is to install a kind of expander - an extension.

Scheme: extension for interior door

This element consists of 3 strips - 2 vertical and 1 horizontal. With their help, it is quite easy to enlarge the area that covers the door frame - i.e. “get” the required centimeters. The part you need can be purchased together with the entire structure or separately. If you have the necessary tools and materials, make the additional strips yourself.

Advice. One of the main criteria for selecting a product is its similarity with other details of the interior design. To make the addition look organic and not stand out from the general background, carefully select it, focusing on the color and texture of the door and frame.

It is difficult to highlight the pros or cons of this part - this is just one of the possible options that allows you to fill the width of the box. Those who chose this method note the following features of the extras:

• due to its use, you can install the door quite quickly;
• using a strip allows you to avoid wet finishing of the door, which is not very beneficial for wood (using wallpaper or plaster);
• thanks to this detail, the stability of the entire structure increases;
• an interior door with an installed extension looks much more attractive and has a finished, presentable appearance.

Attention! In cases where the door jamb is severely skewed, and the door leaf was adjusted to fit the deformed frame, additional adjustment will not help. First you need to redo the structure itself.
