It often happens that the floor in the neighboring rooms is different in height. This phenomenon is often not only due to oversight and miscalculation of the builders (in this case it is necessary to level the floors themselves). We are talking about cases where, for example, linoleum is laid in the hall, and laminate in the corridor. The same problem is typical for a shower room or a bathroom when tiles are laid as a floor covering. To solve this problem are capable of thresholds intended for sex with a difference.
Since there are quite a lot of varieties of them, it is worthwhile to learn about the pros and cons of each model, determine what sizes are needed in each case.
Aluminum rails of different levels
Products of any configuration and complexity are easily manufactured from aluminum. Why for the floor is often chosen precisely the metal interior thresholds, can be explained simply:
- light, but strong products will last long;
- can be used both in residential and non-residential premises, as they are not afraid of changes in temperature, load and humidity;
- aluminum pores are narrow and wide, and the oxide film applied over the docking profile allows imitating various coatings - gilding, bronze, silver;
- you can find any size, and if the doorway is non-standard, then the length of the threshold is easily shortened with a hacksaw for metal or a Bulgarian.
Metal interior threshold - the best choice
Smooth surface allows you to create a smooth transition in the interior gap, this decision makes the height difference visually less noticeable. But it is worth considering that it is easy to slip on this door. If the house has small children, it is better to choose a similar product, but with a fluted strip in the middle. Such models are relevant for the bathroom.
Installation is simple: a screw is screwed into the existing fixing holes, ensuring a tight fit to the floor surface.
Among the shortcomings, one can note the limitation in height. Aluminum products, if they do not have a special shape, are able to hide the difference in the floor no more than 10 mm. In addition, not everyone likes that hardware is visible against the background of the door. In this case, manufacturers offer docking profiles with concealed fastening.
How to hide screws?
To equalize the difference in the height of the floor in the neighboring rooms, you can choose a threshold with a hidden anchorage. Installation will be simple, the essence is this: first to the floor screws are attached to the lower bar, and on top of it is put on the second part with a decorative pattern.
Aluminum docking profiles are easily seated on the hardware, unless the floor is not concrete. Otherwise, the installation will take place in the following order:
- The cut-off threshold should be disassembled and the bottom part applied to the base.
- On the available holes for self-tapping marks mark or pencil.
- In the places of marking, the holes for the dowels are drilled with a perforator.
- The installation is completed by fastening the door with screws that will firmly fit into the special socket of the dowel.
The interior threshold can be fixed independently
Now you can put on a decorative bar, and the height differences are eliminated.
Flexible interior thresholds
Flexible joining profiles allow you to realize bold design ideas when the place of joining different coatings is not in a straight line, but, for example, bends in a circle or a wave. In this case, the turning radius can be quite steep. Due to which such a threshold removes the height differences on the floor?
Thermoplastic, from which the profile is made, plastic, but durable and durable. The lower part has incisions on the ribs, which allows you to bend it, achieving the desired shape. The upper decorative strip, due to the flexibility of the material, conceals a slight difference between the coatings. Use this threshold is appropriate for switching from tiles to laminate and from carpet to parquet board.
Among the advantages of the product can be called:
- a wide range of colors;
- installation, accessible to any domestic craftsman;
- possibility to create a bend in the range of 30-60 °;
- the profile does not creak when it is attacked, but the metal pins have such an unpleasant property.
Do not run to the store for such a wonderful invention, if the height difference is more than 20 mm, the flexible profile with it simply can not cope.
Alternative options for padding
Variety of assortment of decorative thresholds allows you to choose the best option
The store can offer other types of docking profiles, differing in price and material from which they are made. Their brief characteristics are given in the table.
| Profile type | Nuances of use | Note | Evaluation |
| Rubber floor pads. There are two types: completely made of rubber or an aluminum profile with a rubberized coating. | Ideal for the bathroom, often used at the entrance to the house, preventing slipping. Mounting is carried out on the dowels, if the base is made of aluminum, or on a special glue, if this profile is entirely made of rubber. | Rubber bends, bent at right angles, are designed to decorate the steps. They have a different shape, if used to level the level of floor coverings. | They can hide minor differences, are practical, but do not have special aesthetic properties. More appropriate in swimming pools, baths or utility rooms. |
| Wooden transitional profiles for the floor | For installation, you must first install the mounting rails and already on them to install decorative nails. | The sizes and colors can be various, that is caused by rich color scale of floors from natural wood. | The price for such products is quite high, but they are mandatory if the floor covering uses an expensive parquet board. Wooden thresholds are whimsical, will require additional care and will not hide the big differences (maximum is the transition of the parquet - carpet). For a bathroom, they, naturally, will not work. |
| Plastic pins | Polyvinyl chloride is a fairly flexible material, so plinths from it are purchased for the design of curvilinear curves with a small radius. | The color palette is diverse and easily selected for laminate, linoleum or carpet. | A small cost justifies an insignificant service life. PVC is not afraid of water, so it can be used in the bathroom. The only nuance - you can slip on it. |
What other transition profile is suitable for a bathroom
The most common solution, if the floor level in the bathroom is higher than in the corridor, is the installation of a door with a door, which is purchased immediately with a door frame.
If the difference in height is not too large, you can choose an angled aluminum profile.
- Due to the polymer coating, it is not afraid of moisture, which is an integral companion of the bathroom.
- You can find different sizes that will make it possible to smooth the difference from 5 to 15 mm.
- Installation is carried out by open method on self-tapping screws.
Special profiles for tiles are arranged so that it is filled in them. As a result, a neat edge is obtained, but the transition to a different type of coating remains visible.
Using decorative padding allows you to hide the difference in height of the flooring
Against the background of the foregoing, aluminum and flexible transition profiles are a good way to decorate the differences between the coatings with aesthetic and neat. And if the difference in height is significant, then you need to forget about interior decorative planks - the problem will be solved only with the installation of a door frame with a high wooden threshold.
The flooring will not look as attractive and elegant as it was planned, without such an obligatory decoration element as the floor pads. You can draw an analogy with a woman who is dressed stylishly and expensively, but picks up cheap and unattractive accessories for her. Therefore, to buy the threshold should be treated no less deliberately than to the choice of flooring.
Choosing this product, the buyer, as a rule, evaluates many factors - design, structural strength, as well as texture and material used for manufacturing. But in fact, it is necessary to pay attention to the purpose of the nail, as well as the way it is fastened and many other points.
Variation of thresholds
During the installation of a different type of floor covering, gaps and gaps remain between the opening and along the walls of the room. With the temperature expansion of materials over time, such floor imperfections change their geometric dimensions. Therefore, to remove slots and make the junction more attractive, plinths are installed between the cover and the wall, and decorative doorways are installed in the doorways.
They can be represented by several varieties:
- Single-level thresholds are designed for the design of joints of surfaces of the same level. That is, the difference in heights between the coverings of the rooms is minimal or completely absent.
- Various levels are used to make the joint of floor coverings with a significant difference in heights. For example, when the thickness of the linoleum is 2.5 cm, and the thickness of the floor covering from ceramic granite or wooden board is about 6 cm, the paddles allow to compensate for this difference.
- Angular threshold - a convenient element for finishing the corners of the steps both inside the house or apartment, and outside.
Considering all this, when choosing a decorative threshold, it is necessary to remember the thickness of the floor covering, which will need to be covered by this element. The multi-leveled pushers are more complex in configuration. It provides smooth smoothing of the height difference during installation and operation, excluding the inconvenience of walking.
About the materials of manufacture
The threshold can be represented by slats of various sizes, produced from a variety of materials. The choice of a particular product depends largely on the type of flooring used, as well as on the owner's material capabilities.
Aluminum products
Assortment of doorsteps
Naturally, the metal decorative thresholds will be the most durable, as they withstand any temperature fluctuations and loads. The most popular of them today are aluminum sacks.
This is explained by the strength of the material - such elements are able to withstand significant daily mechanical loads in places with high traffic intensity. In addition, they are not susceptible to corrosion in comparison with other metal structures. In addition, the aluminum threshold in the production is covered with an oxide film simulating gold, silver, marble or natural wood. They are lightweight and can be mounted simply by means of existing mounting holes.
Rubber tongs
Not less popular are rubber products, which have proven themselves only on the positive side. They can be completely made of rubber or have the appearance of an aluminum product with a rubber insert.
This is used as an anti-slip coating, as a rule, for surfaces finished with ceramic tiles and steps. Mounted rubber nails with dowels, if it is made on an aluminum base, or with a special glue.
Cork products
Smooth transition from one floor covering to another
Cork pins are made in the form of a cork slip, which has excellent damping qualities. Therefore very often similar elements of a covering for a floor name compensatory rejki.
They can be represented by a variety of forms, for example, zigzag or semicircular. The cork threshold is glued to the floor at the joints of the finish coat, without protruding above it. As a rule, it is used as a single-level padding for the parquet.
Thresholds from MDF
MDF products are mainly used to hide laminate joints. They are laminated in the tone of wood profiles, which are subject to humidity.
They are characterized by low cost and a short period of operation - much less than wooden or plastic doors.
Thresholds made of wood
Wooden thresholds are produced from a natural massif and are perfect for decorating a parquet floor. In this case, the thresholds should be selected in the tone of the coating and from wood, similar to the basic finish.
To install such a product, you should use special rails, which are attached to the floor at the junction points, and only then the nails themselves are fixed to them. The only nuance that must be taken into account when buying such an element of decor is that the wooden product requires constant care - polishing, varnishing or special coating. The price, which has a threshold of wood, is high enough, provided that you will be offered quality material.
Plastic pins
Bending radius up to 60 cm
Plastic pushers are made of polyvinyl chloride, have an extensive color gamut and are used to mask the joints of laminate, linoleum and carpet.
The advantage of this product is its flexibility, which allows the use of plastic thresholds for the decoration of curvilinear connections. One-level and multi-level PVC padding is inferior to other products for floor decoration.
Fineness of installation
For mounting decorative thresholds, fixing elements and glue are used. The threshold before installation should be cut off on length which should correspond to distance between casing doors.
Products can be attached in the following ways.
With open mounting
With this way of installing the paddle, the fastening elements remain visible. This is an option for mounting aluminum products, because they already have holes for fixing in production.
The upper part of the screws that come complete with the door are painted in the tone of the decorative element. For the installation in the installation site, drill the holes, then clog the dowels, into which the screws are screwed and the threshold is fixed.
With concealed fastening
Slides in the bathroom
With concealed installation, the lower profile (fixing nut) is initially fastened to the screws or glue, and then the upper bar snaps into place. The height of the fastening element should be the same as the thickness of the floor covering.
There are several ways to achieve this:
- application of a paddle with a metal zigzag profile;
- select the fastening profile of the desired height.
In addition, you can glue the lower profile to a self-adhesive tape or glue, but this is not entirely convenient. After all, soon you will have to re-install, since such a fastener is weakening after a certain period of time.
Stages of installation:
- with the edge of one floor covering, the lower profile is fixed;
- a second coating is applied;
- the decorative rod is mounted in the guide rail;
- through the bar with the help of a hammer, the whole structure of the door is snapped.
Conclusion
Attractive external design of joints, joints, corners and vertical swings - this is an indicator of the quality of the work done.
The purchase of the padding and its installation allow not only to solve the problem of combining different in the texture and color of the floor coverings, but also to prolong their service life, and also to facilitate their care.

The final touch in the laying of the flooring will be the floor pads, which securely fix the edges, close the joints, crevices from debris and moisture.
The overhead bar will harmoniously arrange the transition from room to room or combine in a successful composition the combined design of floor coverings from different materials.
The threshold configuration depends on its function
The variety of thresholds for sex is due to the combination of those complex functions that it must simultaneously perform. Depending on the installation site, not all the properties enclosed by the manufacturer can be constantly in demand, but, nevertheless, when choosing to take them into account.
Important features on which are selected in the interior of the apartment, such elements as the floor thresholds, are reduced to several main groups:
- the size of the closed slot (wide clamping part or narrow);
- profile, flat or under the level difference (the edges of the adjacent floor coverings can form a step);
- combination with the main tone of the floor (the top of the bar can also contrast the materials, emphasize the doorway);
- intensity of the load (service in the places of the main passages or especially unloaded parts of the room);
- appearance (the same materials have a different pattern open surface view, can be performed with hidden fastening, anti-slip overlays).
Each manufacturer declares a long life of its product. It should be remembered that plastic, aluminum, wood and brass floor rapids will look different if the next repair takes place not soon.
Plastic
Each material has its advantages in certain operating conditions. Polymeric compositions have proved themselves in rooms with high humidity (kitchen, bath, bathroom). To this category can be attributed and a more flexible variety - rubber frames.
Curvilinear boundaries create a special flexible edge, evenly lying on the complex shaped edges of the flooring. Reflected from its figured line, the light will not show signs of violence when mounted by oneself.
Additional options of plastic threshold models - option with a cable channel. The insulator protects the host from accidental exposure to electric current, dense polymer - wiring from mechanical damage.
Tree
Wooden thresholds non-budget option Wooden interior thresholds can harmoniously complete the rectangle of the doorway in one piece or merge with the textured tone of the laminated flooring.
This type of padding is quite expensive and is often used to complete the design of the wooden floor in the country residence. If a flexible connection is required, the plugs are made of cork.
For a laminate under a tree, the MDF components that match the color and pattern are taken.
Metal
Metal bars well press the linoleum and close the joints The most popular threshold for the floor is because of its strength, reliability in operation, durability and pleasant appearance.
Metal thresholds made of brass and aluminum are produced, more rarely stainless steel (the hardest version). More flexible aluminum floor strips at installation easily will close insignificant roughnesses, tightly press a linoleum, a carpet, a tile. It is essential that a sufficiently soft metal, pressing, does not damage the base material.
To give a diverse and noble appearance, the aluminum alloy is anodized for bronze, gold or silver. Such colors are suitable for almost every floor material, advantageously emphasize by their framing the basic tone of the floor, give the situation completeness.
The deposited layer reliably protects the aluminum threshold formed by the film from aggressive chemical influences.
Level difference
Brass and aluminum thresholds for the floor for different tasks make of a profile of 3 types:
- flat (the upper side can have a convex shape);
- angular (transition step, difference in thickness of adjacent decks);
- T-shaped (for installation on joints of materials of different structure, for example, tile / laminate / parquet).
Where the level difference forms a pronounced step, to maintain the integrity of the edge and protect the legs put an angular profile.
The design for multi-level transitions can be combined or integral (with a given angle of inclination and width of the closing surface).
Significantly more versatile in the possibility of using aluminum prefabricated thresholds. They can be adjusted in the range of 3 - 15 mm.
Some installation moments
A rigid threshold profile is produced in standard sizes along the length. In each individual case the material is cut to size by a manual or circular saw. With visible screws of screws cut the bar for the doorway is desirable so that it looked symmetrical - in equal parts from each edge. For more information on how to set up different types of thresholds, see this video:
Flexible thresholds, some manufacturers produce in rolls, so they can be purchased at a common footage, cutting into place yourself.
Simple flat thresholds are mounted without technical difficulties for liquid nails.
The sales package may include screws for surface mounting. They are screwed through right up to the full immersion of the cap into the countersunk hole. In some modifications, the hats can be hidden under the overlays, including non-slip composites.
Another type of attachment - locks for hidden fixation. In this case, the hollow part of the lock is fixed firmly on the base, and the protruding element of the covering strip is enough to be combined with the groove and press it until it clicks. For more information about flat flap, see this video:
In any method of installation, the tightness at the edges should reliably prevent water from penetrating the enclosed space. This can provoke the development of putrefactive processes under the materials of sex.
To hide the junction between different floor coverings , as well as possible differences in the unequal level of the floor, it is customary to use a functional design - the interior threshold. This small part is mounted between the rooms, in the corridor, bathroom , as well as near the front door. At first glance, it may seem that setting the threshold of the interior door is a simple matter. Somewhere it is, but if you do not take into account some of the nuances, then you can experience small difficulties. If you want to understand this issue in more detail, then to your attention this article.
Interior threshold - a detail of the interior, which is subjected to high loads and constant mechanical impact. This is due to the fact that it protrudes from the general level of the floor by a few millimeters. Given this, it is important to pay special attention to the choice of this detail. To begin with, consider its features:
Pluses:
- Not only a massive wooden door absorbs noise, the nails also copes with this task.
- With the installation of the threshold, less dust and drafts enter the room.
- If there was a flood in the bathroom, the threshold can prevent flooding of neighboring rooms. However, with significant flooding, this construction will be useless.
- When food is cooked in the kitchen, the threshold does not allow smoke and garbage into the living rooms.
Disadvantages:
- Often, because of the rapids, especially children, fall, as it protrudes above the floor.
- If self-tapping screws are badly screwed into the threshold, this can be the cause of leg injuries.
As can be seen along with the merits, there are not that many shortcomings in this subject. Now you need to decide which material is best to purchase the threshold.
Today, the market is flooded with a lot of building materials, this also concerns the doorsteps. To your attention, we suggest you familiarize yourself with thresholds made of different materials:
- Stainless steel.
- Bronze.
- Brass.
- Aluminum.
- Plastic.
- From the laminate.
The most popular material, from which the most frequently made interior thresholds are metal. In this category, stainless steel, aluminum, bronze, etc. Due to the resistance to weathering, they can be installed on the street.
The thresholds of this material are resistant to mechanical stresses. On sale you can find both painted products, and anodized.
Stainless steel
Due to a matte or glossy finish and silvery color, stainless steel sashes are rarely installed on the floor. Most often they are used in furniture or for finishing walls.
Bronze
This type of material will be very expensive. Plus, on sale it is difficult to meet the threshold of bronze. Therefore it is worth ordering. But there is a good alternative. "Under the bronze" an aluminum threshold is made. In the price it is more affordable.
Brass
If you want to have a beautiful threshold of golden color, then brass is an excellent material. This valuable material will be quite expensive, but the appearance will pay for all costs.
Aluminum
Lightweight and reliable paddles are made of an alloy of various metals that are in aluminum. Their affordable price is in perfect harmony with continued operation.
The thresholds of aluminum or steel are often covered with monochrome paint or a successful imitation of a tree. Also, the aluminum profile is laminated with a strong film. Due to this, the type of tree, stone, etc. is copied.
This is one of the common materials that is used to install the interior doors . If you want to have a durable threshold, then it is recommended to purchase an oak threshold.
Oak pills are expensive, plus they need systematic care, namely painting and varnishing.
Plastic
Between metal and wood, the plastic threshold is average in terms of durability. This element has a large range of colors. But its main drawback manifests itself under intense loads, as a result it can burst.
From laminate
If laminate flooring , then it is advisable to use the threshold from the laminate. However, in conditions of high humidity, it can deform with time.
This material is usually used on the threshold of the balcony. It has no shrinkage and is durable.
In addition to the material used, this object also differs in appearance. This is very practical, because due to the variety of forms it is possible to cover the thresholds of different complexities. Below are the main types of constructions of this element.
Overhead or flat
They are plastic or metal plates having different shapes. They can be successfully used for coating of all kinds, for example, laminate, carpet and linoleum.
Such a threshold is called an invoice, since its fastening is carried out from above.
Transitional or multilevel
If you want to hide the transition from different floor coverings, then this type of threshold will properly perform the task. Transitional thresholds will block the difference in height from 3 to 15 mm.
In shape, they are most often rounded or in the form of a developed angle.
Corner
In this category, aluminum thresholds are most commonly used. Often there is a difference between the room, forming a small step. In such cases, such a threshold will be an excellent solution. The surface of the corner element is usually perforated.
Angle thresholds are also installed on the steps. A perforated surface prevents the sliding of shoes.
This type of threshold is made of safe and hypoallergenic plastic. Under the influence of high temperature, it becomes elastic, due to which it acquires the desired configuration. This material is sufficiently resistant to mechanical influences. Most often they are used to hide the thresholds, finishing columns, podiums and pedestals.
T-shaped
These products have a different width and color. Under their feet they are almost imperceptible, since they are absolutely smooth. They can hide the radial transitions between this or that coating.
This type of threshold is predominantly made of metal, and sometimes of plastic. They are equipped with holes for fastening to the floor. To make the hats of the screws self-hiding, the holes are fitted with a conical shape. The holes themselves are arranged in 15 cm steps. This is the simplest type of paddle, with the installation of which everyone can handle.
This element has no holes for fastening. The fastening element is hidden under the bottom of the structure itself. If the threshold difference does not exceed 15 mm, then this type of profile can be safely installed.
This is one of the latest developments, which in form resembles the letter P. It is made of aluminum with a spring device and a rubber seal. Installation is carried out in the end of the door unit, so that when the door is open such a ridge is not visible. When the door closes the guillotine automatically falls down and completely closes the gap between the door and the floor.
This structure organizes high-quality thermal insulation and noise insulation. The main advantage is the complete absence of drafts. Plus, the threshold does not interfere with the movement. A clever threshold can be combined absolutely with any door.
This type of padding is not suitable for hollow doors, since its tie occurs at a depth of at least 2 cm. Additional carpentry will also be required.
So, we decided on the types and materials from which the pills are made. Now consider the methods of their installation. It should be noted that there are several technologies for their fastening. It depends more on the type of product design. The only thing that unites the beginning of installation works is the measuring process. You should make precise measurements of the opening and cut the threshold with a hacksaw or a Bulgarian.
This method is very simple. The bar is equipped with mounting holes. To fix it, you need to mark with a pencil the marks for drilling in the floor of the holes. Do not make too deep holes. Otherwise, the screw with dowel may later loosen. You still have to tighten the screws and put on decorative hats.
Most often preference is given to rapids with a hidden fastening system, and in most cases from aesthetic considerations. In this case, the slats with floating holes for the fastening cap are used, which consist of a rails and a T-shaped flange. The method of attachment is as follows:
- First of all, drill holes in the floor. In them you insert plastic dowels. Then gently string the screws for the hat on the bar. After that, you need to send the screws into the plugs. In conclusion, you can slightly tap on the bar by laying several layers of paper or thick cardboard.
- If the threshold has the shape of the letter T, then drill the required number of holes in the floor. Then fix the bar to the floor with screws, and the top decorative part of the door is snapped on or fixed on top.
In this case, extreme attention is required. In this room most often on the floor is ceramic tiles. Therefore, you will have to purchase a threshold that will not allow moisture to pass through. Just in this case, the ideal option would be a system - a smart threshold.
So, as you can see, the technique of setting the threshold with your own hands is quite simple. In addition to the functional load, it will give the floor a complete appearance. Therefore, you should not postpone its installation for later, but better immediately perform this work. If you know other important subtleties of doing this work, then leave feedback and comments at the end of this article.

Rarely where you can find floor coverings without a threshold connection. This device has a small area. It is based on the technical features of the finishing finishes.
To qualitatively and under one style to make out the floor, rapids are required. The color palette, the size range and various materials allow you to dock any floor coverings. Consider what they are for, what options exist and how to install them.
There are three main areas of use:
- Application in design. New styles, technologies, materials sometimes form unique interiors where several floor coverings can be combined on the area of one room. Gently close the border between them are allowed just paddles.
- Joints between rooms. Such places are most vulnerable to mechanical impact. Especially if they are mating materials or overlapping the difference in the level of the height of the floor between the rooms. In addition, manufacturers of flooring put a restriction on the area of installation without a threshold. This is due to technical features. Any material can change its linear dimensions under the temperature drop. In such cases, thresholds are needed.
- Anti-slip angle profiles. Used for stairs lined with tiles or natural stone.
The patterns perform the following functions:
- Aesthetics. Close the technical gaps and the boundaries between materials.
- Security. If the docking is not covered with a protective bar, then eventually the edges of the material will bend. About them you can stumble and fall, getting serious injuries. Security is provided by angled anti-slip profiles. Their use on marble or tiled stairs is more than justified.
- Fixation. With the help of thresholds, the edges of the floor coverings are firmly fixed and hidden, which ensures their long service life.
Given the scope of application and functions that bear the thresholds, it is impossible to overestimate their importance for high-quality finishing of the floor.
Varieties
Several classifications are distinguished. The first of them is based on the material of manufacture:
- Wood. Depending on the method of attachment can be completed with a special mounting profile.
- Metal. In turn, they differ in the way they apply the decorative layer: anodized, laminated, dyed, polished, chrome.
- Aluminum. Can be attributed to a metal or a separate group. They have a natural design or with imitation for any kind of natural finish. The most popular and sought-after species.
- Flexible plastic or rubber. This view is the most flexible.
- Plastic. Have found their application in docking the laminate. The quality of such compounds is considered to be weak.
- Cork. Such products have a damping property. Over time, they can get out.
By design, there are several more types:
- Direct. They are used for fastening in the open way, when the jointing takes place on one level.
- Corner. Are applied on the steps, high thresholds. Can be used as a final profile when docking high levels of floor differences.
- Leveling. Used on coatings with a drop. In such a profile, one side lies in a straight line, the second is at an angle with respect to the first.
- Curvilinear. Have a good plasticity, which allows you to make a unique design with a combination of different materials.
There is another classification according to the section of the profile: T-shaped, U-shaped, L-shaped, C-shaped, Z-shaped. The abundance of assortment allows to give an aesthetic appearance to any connection of floor coverings.
Dimensions and other characteristics
With regard to the dimensions in which the pores are represented, the width lies in the range from 20 to 150 mm. Length - from 900 to 2700 mm.
Another important factor is the method of attachment. Total allocate two:
- Open. Such panels have prepared technical holes for fastening. Comes with dowels.
- Closed. This method is carried out by gluing a nail or fixing it to a dowel through a special profile. It can be removable or integral with the main decorative part. There are some nuances for editing, but the result is worth the time.
Therefore, when choosing thresholds, a number of conditions should be envisaged. First of all, to connect which materials they will be used.
For what coatings are suitable?
Each flooring requires its own kind of padding:
- Linoleum. For him, the usual straight profile of metal, wood, plastic, cork.
- Laminate, parquet board. The whole spectrum of thresholds from direct to angular is used. The material is also not limited - metal, plastic, cork, wood, rubber. When choosing, you should pay attention to how organically it fits into the design.
- Tile. Usually connect with other types of coatings. The most successful is the use of rubber padding. It will hide the boundary between the surfaces. The design is selected according to the type of connection.
When buying, it is important to pay attention to several points. This will help to avoid difficulties in further installation. 
How to choose the right one?
Before starting the selection, a number of questions should be identified:
- Lenght and width. For non-standard sizes, you may need to order the bar. The width of the threshold should overlap both sides of the docking material.
- The profile and design are selected depending on the type of joint and coating. For example, with strong floor changes, you can apply an angled bar, and with an even surface - a T-shaped straight door.
- Material. The most popular type is metal profiles with a laminated surface for natural fibers. The versatility of this fasteners and assortment allows you to use it with any kind of coating.
- Colour. There may be several options. Classical is considered the choice of a color plinth, door or floor covering. But there are other options, which are tied to the stylistic design. For example, in a hi-tech style, the chrome profile will fit organically. And if you want to emphasize the transition from one material to another, you can play in contrast and choose a darker or lighter shade.
The choice of the threshold also depends on the technical requirements, the design, the size of the budget.
Ways of installation
The installation of the door is not very complicated, but it has its own peculiarities.
The length is measured and cut off at the installation site. The line on which the fixation will be made is determined in the middle of the joint. And the width of the bar should overlap the edge of the material on both sides so that the gap is not visually visible.
Allocate the following installation options:
- Open method. The trimmed profile is applied to the fixation point. The building pencil marks the drilling points for dowels through the factory holes on the bar. Sweeps are removed, holes are drilled, plastic parts of fasteners are inserted. The strip is re-applied so that the holes coincide with the dowels, the self-tapping screws are inserted and tightened.
- Closed way. Mounting with glue is a thing of the past. The following methods of fixation are considered popular:
- Through the bar. Take the sill, insert the necessary number of screws into the special guide. In the middle of the joint between the floor coverings mark the dowel points. Drill, install the plastic fastener parts. Take the bar. The location of the screws is adjusted to the dowels, they are inserted. On the thresholds press, fix. The work is carried out with a hammer. It is important to put a bar or log on the panel to avoid scratching.
- Through the profile. This method is characteristic for T-shaped thresholds. The fixing rail is fixed and fixed with dowels. The facial profile is inserted and carefully pushed through the bar or other material to avoid scratching the outer part.
