Plastic corner - not too noticeable, but extremely important element when decorating walls and slopes. The many advantages of this material have made it popular among private craftsmen and construction and commercial organizations. Affordable price Compared to metal products, it will allow you to buy a polymer corner element, saving your budget.
Products made of polyvinyl chloride have a number of advantages:

• Light weight allows installation on all types of walls.
• A variety of shades makes it possible to choose a color for any situation.
• Does not absorb water and does not form dampness.
• They are easy to install and can be quickly dismantled if necessary.
• Variability of sizes is a significant plus for rooms of different sizes.
• The polymer is resistant to deformation, does not wear out, has a service life of correct installation at least 50 years old.

Performs both aesthetic and technical functions. The variety of options allows you to realize any design idea.

Variety of colors

The color palette includes more than 70 shades. There are positions with imitation wood and metal, so the plastic corner is suitable for both high-tech and classic design. Most often, for standard rooms they try to purchase a bar white, it is universal in its own way. Despite the fact that the white corner perfectly performs its main functions, masking construction errors in joints, it is also invisible after installation due to its neutral shade. Plain profiles are an indispensable attribute in office and large production premises, used to hide defects and protect the corners of walls, the planks are attached to liquid nails and blend in with the shade of the walls.
Designers advise choosing a shade that is a shade darker or that matches the color of the wall, but in modern styles, playing with contrasts often turns out to be advantageous, so the scope for choice is another advantage of plastic corners; moreover, if installed correctly, it will last for decades.

Types of plastic corners

Protruding elements are the most fragile parts in the room, often subject to accidental mechanical influences, therefore it is important to promptly and correctly select and install the frame, focusing on color scheme interior interior.
Polyvinyl chloride corners can be divided into several types according to the place of application:

• External - masks the outer edges of the protruding elements of the room. Copes well with the mechanical effects of accidental impacts, especially when furnishing the interior with furniture.
• Internal - used at the joints of walls or floors, serves mostly a decorative function.
• An arched corner is indispensable when framing curved joints. Due to its properties, the flexible element is popular in non-standard design solutions. Which in turn has an undeniable advantage over metal products.
• Self-adhesive universal - based on the name, it is suitable for framing any junctions. Due to its flexibility, it can be given any degree. Takes properties at room temperature, so in winter period After transporting the material, we recommend waiting at least two hours before installation.

This page presents positions from world leaders in the production of decorative plastic corners. Polish Cezar and Lemal and a German manufacturer of universal self-adhesive corners.
No installation required special skills, produced for liquid nails. In the case of self-adhesive elements, you need to tear off the tape and place the profile on the joint of the walls. You yourself regulate the installation location by bending the element; due to its versatility, it is suitable for all types of connections of load-bearing structures.

Newly installed PVC window with beautiful window sill looks stylish and neat. But this composition lacks aesthetic completeness: the outer edges of the slopes and the joints with the frames do not look very presentable. To bring the appearance of windows to the ideal, plastic

Features of corners

Decorative corners for slopes are made of rigid polyvinyl chloride using a thermal method, with the help of which the sheet bends without cracks. Application – masking the gap between the window and the quarter, protection polyurethane foam from moisture, ultraviolet radiation, etc.

You can process any slopes: window slopes, doorways, incl. non-standard (arched, etc.) Corner is not only a decorative element, but also protects the corner/joint from any external influences. Its advantages:

Hygienic, easy to clean;

PVC corner for slopes does not require any additional processing;

Durable (up to 100 years of service);

Cheaper than similar profile products made of metal and wood;

You can buy plastic corners for slopes at any hardware store;

Protects foam and other materials (edges of wallpaper, etc.) from destruction;

Hides uneven corners and joints;

Has a lot color solutions. Thanks to lamination, the surface can imitate the texture of other materials;

Corners for doorways easy to install with glue, liquid nails, silicone;

Goes great with plastic panels, plasterboard shelves and arches, ceramic tiles, siding and even wooden clapboard.

Types and sizes

Plastic corners for slopes vary:

Profile shape – L, F, P, T-shaped;

The width of the shelves is symmetrical and asymmetrical;

The shape of the opening is straight and arched;

According to the installation location - for interiors and facades.

Plastic corners for slopes have standard sizes symmetrical L-shaped corners - from 1 by 1 to 10 by 10 cm, the length of one part is two to three meters. Asymmetrical - 2.5 by 1 cm, etc. The arched corners are bent strictly 90 degrees, the length is 2.5-3 meters.

In addition to decorative ones, there are perforated plaster corners for window slopes with a sickle mesh. They are designed to strengthen corners for sealing with putty or plaster.

Facade corners, like similar elements for interiors, can be external and internal. External facades can be curved:

Under 90º. One shelf of this element remains outside, the second is inserted into the gap between the frame and the quarter;

Under 105º. They are placed with both shelves facing out. Disadvantage: with this finishing method it is impossible to install a mosquito net on the window.

How to attach corners to slopes

Before gluing the corners to the slopes, it is necessary to clean the narrow strip along the corner/joint on the working surface from anything unnecessary: ​​dirt, cement and putty blots, wallpaper, etc. The corner must be glued directly to the base; fixation to the finishing material will be less reliable. The corner shelves should overlap the stripped strip by at least a couple of millimeters.

1. Apply a dotted strip of glue to both corner shelves.

2. Press firmly to the place of gluing.

3. Secure with masking tape while it hardens.

Price

The price for a plastic corner for slopes is more than affordable:

3 meters, 1 by 1 cm – from 25 rubles;

2 by 2 – from 40;

Plastic corners for slopes 7 by 7 - from 150, etc.

To make the inner corners of the window opening smooth and beautiful, a special plastic corner for slopes is used, as well as similar profiles from other materials.

What is a plastic corner for slopes?

Internal surfaces window openings today they are often finished with plastic, since it is the most affordable and cheap material even in comparison with drywall. However, the ends of the plastic strips with partitions look unpresentable, and to decorate the finish, experts use plastic corners for window slopes. In fact, these are profiles included in the set of facing panels and having an L and F-shape in cross-section. They are made by hot bending a rigid sheet of polyvinyl chloride.

The profile shelves have different sizes, the angle between them is usually 90 degrees. As for the dimensions, with a length of 2 meters or more, the width of the shelves can be 10x10, 15x15, 20x20, 25x25, 30x30, as well as 35x35 and 40x40 millimeters. Less common are corners with asymmetrical shelves, such as 25x10. It’s worth remembering the profile for finishing arched openings. It is a flexible corner with a single standard for the width of shelves converging at an angle of 90 degrees, the length of which can be 2.5-3 meters.

L-profile is usually used to complete the surface cladding with plastic strips, installed on the inside corner with a butt joint. The F-shaped angle is mounted on PVC ends panels, masking their uneven cuts with clearly visible stiffening ribs; it is for this purpose that the profile has an additional jumper. Often, a plastic corner for slopes has a shallow flow groove along the fold line, thanks to which the angle between the shelves can be changed without the risk of breaking.

Where are aluminum slope angles used?

Very often, increased rigidity overlays are required on internal and external corners. For this purpose, aluminum profiles are used, which are a narrow long corner, in the range of 2.5–3 meters, with a shelf width of 2.5 centimeters. There are two types this profile: decorative and perforated, the first has smooth surface shelves, the second - perforation along the entire length. Holes with a diameter of 2.5 millimeters are drilled, as a rule, into checkerboard pattern, they are necessary for firmly fixing the corner in a layer of putty or plaster when forming wall corners.

Aluminum corners are used as furniture trim, for leveling the edges of tiles, and, of course, for finishing the slopes of windows and doors. This decorative profile can be used for various needs; lightweight structures are assembled from it, in particular for false ceilings. Particularly convenient aluminum corner with a reinforcing fiberglass mesh attached to one of the shelves, which can significantly strengthen the layer of glue or plaster. However, only perforated corner elements are equipped with such an addition, while decorative ones are simply mounted with glue or silicone.

Aluminum profiles have straight or rounded corners, and are also supplied with paint, powder polymer or anodic oxide coating to increase wear resistance.

How to choose a decorative corner for slopes

Carefully executed finishing of windows and door slopes, outlined by the straight lines of the opening, will decorate any room, regardless of the design style. However, for this you need to choose the right decorative corners, necessary for framing the lining of the internal surfaces of window openings. Any corner profile is suitable as such: plastic, aluminum or brass (with the exception of the perforated version). The most accessible, due to their low cost, are polymer corners, but special beauty cannot be achieved with their help.

Smooth aluminum profiles with a shiny or matte surface they look more aesthetically pleasing, but are not suitable for every interior. In particular, they don’t go well with everyone classic styles (baroque, rococo, empire style), as well as with a country style design. Aluminum corners will fit better into a room where minimalism, modern, hi-tech or, as a last resort, gothic interior. Fans of the direction techno will also find special charm in finishing window and door openings with aluminum.

And without any doubt, an expensive brass decorative corner for slopes will fit into any setting. The copper-zinc alloy may also contain lead, nickel, aluminum and other additives, which determine the type of profile coating. This can be blackening, silvering, gilding or patina. Almost any corner option from those listed will be appropriate in a classic or modern style interior for decorating window and door openings. Patination looks especially beautiful, that is artificial aging profile surface. You can purchase uncoated brass corners that have a natural clean finish. yellow or with a grayish tint.

Installing corners on window slopes

When the lining of the inner surface of the opening is finished, all that remains is to refine the resulting result with the finishing touches. It is precisely for this purpose that decorative corners on the window slopes are needed. When purchasing them, you should make sure that the profiles are absolutely flat, with symmetrical sides, without deformations. Before gluing a plastic, aluminum or brass profile, you should carefully align a narrow strip of wall around the perimeter of the window opening. To do this, the screws of the curtain cornice are removed, and any silicone or plaster deposits or glue deposits remaining after finishing the slopes are cleaned.

Next, you should take a corner and measure a segment for gluing the upper part of the opening so that the ends protrude on both sides of the slope to the width of the profile. This is necessary for cutting at 45 degrees the joints with the side stripes, which are marked secondarily, also with the protrusion upward. The lower corner is cut off after all the previous ones have been measured, and only if there is no window sill inside the room. Then you should saw off the internal shelves of the profiles at 90 degrees, and the external ones, for end-to-end connections, at 45 degrees, of course, if the geometry of the openings is correct. To do this, it is most convenient to use a carpenter's miter box, placing a corner in it with the outer shelf facing up.

If finishing the slopes is carried out in an already renovated apartment, and there is wallpaper or other covering on the walls, you should clean a narrow strip along the perimeter of the window opening. Otherwise you will paste the corner on top wall decoration, which will reduce the reliability of fixation. However, wallpaper or other covering should be cleaned exactly to the width of the profile, or even a little less, so that the corner slightly overlaps the border of the cleaned strip. When everything is ready, apply glue with a dotted line on inner surface decorative element and press it tightly against the corner of the opening. To prevent the profile from separating, we fix it while the glue is curing with several pieces of masking tape.

In this photo blog we will talk about installing plastic corners between the wall and the window slopes. I did not clutter up the article “Installing slopes with your own hands”, since it turned out to be too big. Therefore, I made a separate article. So, let's move on to the instructions.

I bought a white plastic corner 15 mm wide and 2.7 m long (22 rubles). I would like to note right away that this width is optimal. It is large enough to hide some inaccuracies in wallpaper joints and uneven slope angles and not so large as to spoil appearance the angles of our slopes. It’s just that wide corners don’t look very nice against the overall background of the entire window (door).

This is what the slopes looked like without a corner.

The first operation is to cut the corner to the length we need. The main thing is not to forget the overlap on the wall is about 2 cm (depending on the width of our corner, that is, 0.5-1 cm more than the width of the corner). This is necessary to make an angle at the junction of two corners. For a better understanding of what we are talking about, you can look at the photo.

We move on to the next operation - gluing the corner. Apply glue to the corner. I used white silicone for these purposes (90 rubles).

It is enough to apply silicone on one side. Since the silicone is white, so as not to stain the wallpaper, it can be applied to the side where the corner adjoins the slopes (the slopes are also white, so the silicone will not be noticeable on them). In my case, the walls are not very smooth, so I applied a little silicone to the other side as well.

To fix the corner to the slopes I used masking tape. It is very important to use masking tape, since part of the tape is glued to the wallpaper. What is good about painting is that it has low adhesiveness and therefore if you carefully remove it later, it will not tear the wallpaper. Of course, if you have the opportunity to stick the tape not on the wallpaper, but on something else that cannot be damaged, then this is of course better. For example, batteries or something else. More details in the photo.

Now we wait for the silicone to set and proceed directly to forming the angle between the two corners. First remove the tape very carefully.

Plastic corners are specially designed for finishing the corners of any door, window or arched openings. There is a huge variety of such accessories, differing from each other not only in shape, but also in color.

Preserving heat in every home includes not only installing good plastic windows, but also of high quality. At the final stage of window installation, there is always a gap on their sides, which can be up to 20 centimeters wide, and this is a problem, since in winter in this place cold air may enter the house.

In this case, simple decorative plastering will not provide bonuses to insulation, and regular ventilation of the room, especially in winter, when the temperature difference is especially large, can cause cracks, which will lead to even greater heat loss.

The most the right way out installation of slopes based on polyvinyl chloride becomes possible, since they are capable of performing not only an ennobling, but also an insulating function. After all, their installation in combination with insulation will ensure the safety home warmth and comfort, and besides, this operation takes much less time than the same plastering.

Finishing work will look seamless if corner profiles are used to decorate window and door openings. Using them, you can hide minor imperfections in plastering and wallpapering, and also provide the appearance of a smooth transition.

They can be used in any finishing and construction work in the house, and are indispensable in cases where the following is required:

1. Change windows.
2. Make an edging in doorways and arches.
3. Protect glued or plastered corners.
4. During installation ceramic tiles.

As you can see, the scope of their application is very wide. They can also act as finishing material internal and external joints panels made of plastic, wood, lining or simply painted, papered walls. They perform not only an aesthetic, but also a conservation function, protecting the corners of the house from deformation.

Advantages and Disadvantages

Most decorative attributes for finishing openings in rooms are made on the basis of polyvinyl chloride, that is, polymers from which most plastic products are made today.

Due to the versatility of this material, any corner profile made from it has standard advantages over analogues made from other materials:

1. Low weight.
2. Widest variety of shapes, colors and sizes.
3. Easy to install, in any way, even with nails, even with screws, and even just with glue.
4. Long service life without changing the basic properties.
5. Relatively low cost.
6. Service, which does not require any costs.

Thanks to the ability to choose material of any color, they fit perfectly into any interior, without contradicting the overall decor of the room and adding completeness to the entire design of the room.

They don't even have any influence ultraviolet rays, therefore, even if constantly exposed to the sun, they do not fade for many years. They are sold in standard sizes, so purchasing material of the required sizes will not be a problem.

Types, sizes

Plastic corners are produced different types and sizes, each of which is designed for installation in a specific location:

Corner L

Has more than others wide application, thanks to its two subtypes: starter and universal. Such a profile is usually designed to hide gaps where different materials join together, as well as to create an edge when using sheet materials finishing and in corner joints.

U-profile

It makes sense to install on initial stage fastening slopes. It is intended for framing and decorating slopes, protecting external corners from deformation and hiding gaps between loosely fastened panels.

F-profile

Due to the special jumper, it can be easily attached to the end sides of PVC panels, even without glue. Its functionality lies in the fact that it can be easily dismantled temporarily, for example, to re-glue wallpaper. His main role– closing the joint between the panels and the wall, as well as – decorating openings and acting as a platband framing a window or door around the perimeter.

T-shaped corner profile

Is the best option to create the effect of a uniform transition between two different materials finishing. It is easy to attach to any material. For example, they are used to simplify the process of laying ceramic tiles on the floor, where they perform the function of improving the unevenness of the tile when it comes into contact with flat surface floor or wall.

Often, the angle between the sides of products, which are produced in size increments of 5 millimeters and the length of these sides from 10x10 to 50x50 mm, is 90 degrees. They are usually used in the design of door and window slopes.

To install a finishing element in an area with aggressive influence of external factors, it is recommended to use elements with a standard size greater than 20 mm. And small corners fit discreetly and ergonomically into the interior of the room.

Varieties by type of finish

Self-adhesive corner

PVC corners differ from each other and the type of finishing work for which they are intended. They are internal and external. The angle for external ones can be 90 or 105 degrees.

The one that is 90 degrees is mounted in such a way that only one bar is visible from the outside, and the second is recessed into the gap of the window frame. And the version with a 105-fold turn is attached with both shelves outward.

The self-adhesive version has exceptional success. It is versatile, since there is no need to buy glue separately for it. They are also flexible, making installation as easy as possible.

Another advantage of such a product is that they are sold in roll-type packaging up to 50 meters long, which means you can purchase almost any length required in each specific case to avoid any joints.

Installation

Installation of plastic corners does not require deep knowledge in the field of construction and can be done independently.

For this, the following materials and tools are used:

1. Sharpened stationery knife or scissors for cutting metal.
2. Specialist. glue or liquid nails.
3. Silicone.
4. The angle profile itself made of plastic.

Before purchasing tools and materials, it is strongly recommended to measure all slopes and openings where it is planned to install finishing elements.

It is better to calculate separately. This will give two advantages: there will certainly be no unnecessary joints and you can select materials of different colors and sizes for a specific place in the interior.

Step by step guide:

1. First of all, prepare the surface of the opening, and you should start by cutting off excess, protruding and protruding parts of wallpaper, plaster or polyurethane foam that interfere with fixing the decorative element.
2. When the surface is ready, the corner itself is covered with an optimal layer of glue, sufficient? so that it sticks, but don't overdo it? otherwise the glue will come out from under it and stain the surrounding surface. Another thing is the self-adhesive version, from which you just need to remove the film and it is immediately ready for installation.
3. It is important to immediately apply the material absolutely correctly, so that you don’t have to adjust its position by smearing glue on the working surface, and self-adhesive products only have one attempt to high-quality installation. In this matter, the main thing is to join the corners clearly, with minimal gaps, or better yet flush, and cut them very accurately. An unsuccessful joint can be easily disguised by filling it with silicone.

As a result, you can easily decorate any window or door opening. The plastic corner profile is made in compliance with all environmental standards, has a permanent color and does not emit odors, and is easy to clean with any damp cloth or napkin.

Price

The price of such plastic products is several times less than similar ones made from other materials, and this is the main advantage of this material, which, combined with an almost eternal service life, makes PVC corner the most popular option for finishing slopes and openings.

What does it depend on:

1. Firstly, depending on the type and shape of the section, as well as the size of the shelves, the larger they are, the more spent on making the plastic corner and the more expensive the product.
2. Secondly, depending on the method of fastening, the self-adhesive corners are already coated with glue, which is included in their price.

Examples of prices:

For example, white self-adhesive corners are sold in rolls, each containing 50 linear meters. The cost of such corners varies depending on the width of the material, so a roll with a 15×15 corner will cost 59 rubles, and 35×35 will cost 72 rubles.

Regular options are presented for sale in 2.7 m lengths and are sold in packs of 100 pieces inside, the price of one piece varies depending on the width, so a product measuring 10×10 costs about 20 rubles, and a version with a width of 50×50 is sold for 90 rubles per piece .

1. The dimensions of the initial profile are determined in accordance with the existing panel. Correctly measured windows and doors and selection of the appropriate length of the corner profile for them make it possible to effectively save money when purchasing it.
2. It is recommended to select materials for decoration already installed window , since in practice it is much easier and more accurate to understand the condition of the openings during dismantling. This approach makes it possible to accurately select the type and characteristics of the profile for decoration.
3. Choosing between materials different sizes , you should be guided by what this particular room where the opening is framed is intended for.
4. If this is a window in kitchen area or the door on the balcony, which requires increased wear resistance due to frequent manipulations, practical option There will be installation of a wide corner profile. It is characterized by increased strength, which means it will correspond to the proper aesthetic appearance of the room for the maximum time.
5. It is not recommended to install elements of maximum width for narrow windows of small size, in this case, for decoration you should choose a thinner profile, for example − 15x15mm, it goes well with the elegant and light interior rooms.
