Do-it-yourself finishing of external slopes of PVC windows. Correction of the situation - external slopes. Slopes for plastic windows. Choosing a method for finishing window slopes: my practical experience

As a rule, replacing any windows leads to the destruction of the adjacent section of the wall. The question arises: what should be done to make the window structure look beautiful and reliably protect from noise, wind and other troubles of the street? The answer is simple: in this case, without repair work not enough. There are various options for sealing slopes, but to choose the right option, it is necessary to consider them in more detail.

About slopes

The sections of the wall adjacent to the window block are called slopes. They are internal and external. Strict requirements apply to internal areas.

The following functions are assigned to the slopes:

• giving window design aesthetic and attractive looking. Can you imagine quality window, which is docked with a broken wall;

• improvement of sound and thermal insulation. Window structures that do not have high-quality slopes do not have sufficient tightness;

• protection of mounting elements and seams from environmental influences. A high-quality slope not only protects fasteners from corrosion, but also reduces the likelihood of windows fogging and freezing.

Thus, slope repair is a list of works aimed not only at restoring damaged sections of the wall, but also at creating additional insulation.

Basically, one of the following repair options is selected:

For any repair of slopes, first of all, high-quality surface preparation is necessary.

Preparing the window opening

Restoration of slopes begins after their surface has been prepared. Preparation is performed in the following sequence:

In order not to destroy the restored slopes, the window sill is installed before the repair begins.

To protect against dirt and broken elements, the window and window sill are protected with paper or polyethylene. It also wouldn’t hurt to protect the window handle and battery under the windowsill.

The protective film on the window is removed only after all work is completed.

1. The surfaces of the slopes are thoroughly cleaned. Large dangling fragments are attached to the mortar.

Plastering slopes

This option for repairing slopes is low cost. For sealing it is enough to have: finishing mixture, a set simple tools and water-based paint.

This option also has disadvantages:

• to get very flat surface, it requires a lot of effort and a lot of time. An experienced installer performs this work much faster;

• Cracks often appear after plastering. This may be due to a single-layer surface coating, when a thick layer slides down. In addition, cracks appear due to changes in humidity or poor quality of the mixture;

• low thermal insulation window designs;

• lack of adhesion to the plastic from which the window is made.

It is believed that for internal slopes plaster looks more aesthetically pleasing than plastic and drywall.

Plastering begins with the right choice and preparing the mixture. In this case, it is necessary to take into account the location of the slope.

• External slopes are subject to special conditions: precipitation, wind, temperature fluctuations. It is recommended to use cement and heat-insulating mixtures with a water-repellent effect. This can be Knauf products or a regular mixture of cement and sand.

• Internal slopes - must have aesthetic appearance. To ensure a smooth surface, use gypsum mixtures. Very common starting and finishing putties company "Ceresit".

In any option, the drying time of the solution is taken into account, since further work decoration continues after it dries.

1. Do not breed a large number of solution. This is due to savings - the unused solution dries quickly.

2. The solution is applied in several layers. The next layer is laid after the previous one has dried.

The repair sequence is as follows:

Covering slopes with plastic

As noted earlier, plastic is in demand due to easy installation and low cost. Besides this, there are other advantages:

• The material goes well with the window profile. The slope and profile have the same expansion, so there is no tension between them;
• are saved performance up to 20 years;
• withstands temperature changes;
• There is protective layer, which does not burn or melt;
• easy care. Dust and dirt are removed with a damp cloth.

The following sequence is selected for work:

Sandwich paneling

When choosing this option, it must be taken into account that the minimum panel thickness is 20 mm.

Without auxiliary profiles, the slope is sewn up within a few hours. The order of plating is as follows:

1. The panels are cut to fit the dimensions of the slope.

1. “Liquid nails” are applied to the panel and it is pressed tightly against the surface of the slope.

1. The gaps between the frame and the panels are sealed.

1. The corners are installed on the outside with glue.

Lining and sandwich panels cannot be repaired. As a rule, they change when damaged. In this case great importance has a choice of shade, as it differs in different batches of material.

Drywall installation

A sheet of plasterboard is a building material in which gypsum is placed between layers of cardboard. An indispensable material for hiding various defects walls, so it is recommended for slopes.

Its advantages include:

• wide range of uses. Suitable for all types of windows;
• can be used to finish slopes of any size;
• low price;
• quick installation;
• environmental Safety;
• painted in different colors.

There are also disadvantages:

• low strength. From anyone mechanical impact traces remain;
• destruction at high humidity;
• rapid wear, requiring additional painting;
• inconvenient installation. When cutting you must use protective equipment, since gypsum dust is harmful to health.

Important!

1. Drywall is the base that requires finishing.

2. It is better to choose a moisture-resistant version of the material that is not afraid of condensation on the windows.

There are several ways to cover slopes with plasterboard, but the simplest is considered to be the following installation using putty.

1. The slope is measured from the wall to the frame. If the wall is uneven, then it is necessary to take measurements in several places.
2. The measurements are transferred to the drywall. For convenience, a pattern is made.
3. The future slope is cut out of the sheet. The material is cut with a knife or sawn.
4. Putty is applied along the edges and in the center of the workpiece.
5. The workpiece is pressed tightly against the slope, and a spacer is installed. It takes a day for good adhesion.
6. Very often, aluminum corners are installed to align corners.
7. The surface of the slope is puttied and, after drying, treated with sandpaper.
8. The cladding is completed with two layers of painting. Wherein window profile and the window sill are protected with masking tape.

In general, everyone independently chooses the method of repairing slopes. If the technology of the work is not violated, then it will be beautiful and reliable.

After installing windows, there are always unsightly slopes that must be masked. This is necessary not only to ensure that there are no drafts and extraneous noise in the house, but also for aesthetic purposes.

Even the most expensive window will look unfinished if you don’t give it a decent finish. If you have only a vague idea of ​​how to install slopes on a plastic window, be sure to read this article.

On this moment Three finishing methods are considered the most popular.

1. Finishing with plastering.
2. Use of plastic.
3. Application of drywall.

Plaster finishing

This is the most common and simplest method as the starting materials are inexpensive and easily available. During the work, mixtures of cement and sand, gypsum or alabaster are used.

They can be purchased at your nearest hardware store, or in a specialized market.

1. All working surfaces are cleaned of dirt, remnants of old cladding, dust. If there are strong protrusions or bumps, then they need to be knocked down using a chisel and hammer.

1. When the solution hardens, smooth out the unevenness with emery cloth, then level the corners.
2. After drying for several days, the slopes are ready for painting. If you want to achieve a perfectly even, almost mirror surface, buy a special primer. Be sure to read the tips for use that the instructions will tell you.

Plastic cladding

PVC sheet trim is a more effective option.

Note!
Plastic is not susceptible to cracking due to changes in temperature and humidity, unlike plaster.
It is not cheap to use, but it is reliable and practical.
And the end result looks aesthetically pleasing.

What do you need for work?

Before installing plastic slopes on plastic windows, you will have to visit a building materials store and purchase:

• plastic in the right quantity;
• slats 1.5 cm thick;
• P-i F-shaped profiles;
• mineral wool;
• staples and stapler;
• drill and self-tapping screws in the required quantity;
• level, marker.

Slope installation

The work is performed in the following sequence.

1. Along the perimeter window frame fix the wooden slats and fix the profiles. Make sure that the rail does not protrude.
2. It is recommended to insulate the gaps. The ideal material is mineral wool, scraps of which are inserted between the frame and finishing.
3. Cover the perimeter of the window with plastic. A window sill (if one was not provided) can be made from scrap materials with your own hands, and then painted in desired color. (See also article.)
4. Decorate outer corners plastic ends between the slope and the wall.

How to finish slopes with plasterboard

Gypsum-based material is well suited for finishing. It has a low price, the sheets are easy to cut and bend if necessary. Drywall will be indispensable if you have installed windows of complex design. In this case, making a vaulted top will be quite easy.

Note!
The disadvantages of the material include the ability to absorb moisture and collect on itself.
To prevent unwanted deformations, you should use special putties and primers for painting.
Then the finish will not lose its given shape even if water enters or changes in temperature.

You will need:

• drywall strips;
• smooth slats;
• polyurethane foam;
• drill with self-tapping screws;
• sharp knife, hacksaw.

Installation of gypsum boards

When you have prepared everything you need, you can get to work.

1. Carefully measure the distance from the edge of the wall to the frame. Take measurements in several places. Walls are often uneven and the distance may vary one way or the other.
2. Make a pattern based on the results and transfer the outline to a sheet of drywall.
3. Now you need to cut out the future slope. The material is cut along the contour with a sharp knife, then carefully broken. You can saw it, but it will take a little longer.
4. Try on the blanks, then fasten the wooden slats of the frame to the edges of the window around the perimeter. Next, screw the blanks to the sheathing with screws. Keep in mind that crooked slats will lead to distortions in the plasterboard strips.
5. Fill the gaps between the strips and window frame polyurethane foam and, after waiting for it to dry, carefully remove all excess by cutting it off with a knife or sanding it off.
6. Often, to make the corners between the wall and the window perfectly even, plaster aluminum corners are used.
7. Now you can putty the finished surfaces and sand them thoroughly after complete drying.
8. Drywall can be painted. It is recommended to apply two layers of the composition, first covering the areas that you are afraid to get dirty with masking tape.

Conclusion

Now you know how to install slopes on plastic windows yourself. Do not put off the work until later; polyurethane foam, which must be used to fill all the cracks when installing a window, is susceptible to negative factors from the outside. Moisture, draft, heat or cold, ultraviolet radiation will lead to its deformation, and even to falling off. Therefore, try to arrange the slopes immediately after installing the window unit.

The video below in this article will help you get the job done in the shortest possible time.

Each of us sooner or later faces the installation of new beautiful windows. As a rule, old windows made of dried wood are replaced by modern ones. plastic structures. At the same time, along the perimeter of the window with inside after dismantling the dilapidated wooden frames and the installation of new Euro-windows, an untreated strip remains, which has a width of 5-15 centimeters, depending on the design of the building. This strip is called a slope; it must be covered. Today we will talk about why this is needed and how to finish the slopes plastic windows with your own hands.

The need to finish window slopes

Cladding the slopes (the inside of a window or door opening) is the final stage when installing new doors and windows. First of all, this procedure is considered necessary from the point of view of aesthetics and completeness. created interior: old slopes are destroyed after removal old window, and you need something to cover the foam assembly seam that is formed when installing new window blocks. But also finishing the slopes allows you to improve the thermal insulation of the entire opening and get rid of many problems with windows.

High-quality finished slopes are not afraid of temperature changes, condensation does not occur on them, and sound and thermal insulation properties the openings are only increasing. But often the window owner refuses to finish the slopes or puts this work aside. Many people have the following thoughts: after all, the window is securely foamed, then nothing will happen to it if it remains without slopes for a while. But, as a rule, this drags on for a long time, and the windows remain in this form for years.

1. The gaps between the double-glazed windows are most often sealed with polyurethane foam, which is an excellent sound-proofing material. The sun's rays have a destructive effect on this foam, and it quickly becomes unusable.
2. Foam in a hardened state increases its volume and “crushes” itself, so after a while a gap may appear between the frame and the layer of foam, which will nullify all efforts to install a window or door.
3. Open foam is not waterproofing material and tends to absorb moisture, which destroys the material when it freezes.
4. Foam that long time, is in open form, loses its thermal insulation properties very quickly: an increase in humidity by only 5% leads to a decrease in the thermal insulation of the foam by 50%.

You can wait to finish the slopes yourself if your house or apartment is going to undergo renovations and redevelopment. In any case, you will have to start with installing new windows. If you have installed windows, cover them with polyethylene film and continue repairs. And the openings can be finished with final stage repair work.

Plastering and painting slopes

The undoubted advantage of finishing slopes with plaster is its low cost. Before work, the dry mixture based on gypsum or cement just needs to be diluted with water. Thoroughly clean the surface around the glass unit, removing all dirt, dust and bitumen stains, and cut off the concrete beads in the corners. For good wall adhesion ( brickwork) and plaster, it is recommended to expand the seams of slopes and corners by 10 millimeters.

After you have plastered the walls adjacent to the window, you can plaster the slopes. Cover the walls with plaster, then level the corners of the slope. We remember that new layer can be laid only after the previous ones have dried, so this method can be called very long, because the entire plastering procedure takes 2-3 days. Often the layer of plaster turns out to be too thick, which is caused by the features and unevenness of the walls.

Apply a small amount of mortar into the groove of the slope, leveling it. Let this piece dry a little. Apply a little more plaster, level it, and continue until the grooves of the slope are completely filled. At one time it is allowed to apply a layer with a thickness of approximately 5-7 millimeters. Level the layer from bottom to top, moving to the sides. Use a trowel to straighten the joining lines.

When finishing window slopes save with plaster small angle between the box and the wall. Make sure that the angles are the same. Before plastering, you can fix a wooden strip with a perfectly horizontal, even edge on the top of the slope. You can fix it with gypsum plaster or nails. You can also install slats on the sides of the slope.

It is recommended to level the plaster using a wooden spreader with a rounded handle. The width of the slope tells you what length to take the fry. One end of the fry is installed on the box, the other on a wooden strip. You can begin leveling the edge of the corner between the slope and the wall only after the mortar has begun to set. Then a top layer of plaster is applied and rubbed.

To maintain the integrity of the earrings at the proper level, flat fissures or roundings are used. After the layers of plaster have dried, the slats are removed. Process the remaining sides in the same way. The plastered corner should ideally be ground into the surface of the walls without any rubbing, and the covering layer should have the same thickness of 22 millimeters along all slopes.

Remember that when working with plaster it is strictly forbidden to open the window. If the mixture gets into the fittings, it can damage them, as a result of which the window will not perform its functions properly. And an even layer of plaster allows the window to open and close normally throughout its entire operation.

However, finishing slopes the old fashioned way with plaster has a whole list of serious disadvantages. The plaster mixture does not connect securely enough to the PVC frame, which ultimately leads to the appearance of cracks between the surfaces of the frame and the slope. Due to seasonal temperature changes and insufficient elasticity of the plaster, cracks form on the surface of the slopes. In addition, the heat-insulating properties of plaster are weak, which leads to the formation of mold and condensation.

Finishing window slopes with plasterboard

Slopes made of plasterboard are already considered traditional. As a rule, preference is given to moisture-resistant plasterboard, which is resistant to condensation occurring on the window. Or ordinary drywall is treated with several layers of primer or a moisture-proofing compound. Moisture-resistant drywall has high level rigidity, good thermal insulation and increased thermal resistance.

The advantages of openings lined with plasterboard over their plastic counterparts are the low cost of the material and the possibility quick repair damage: you just need to putty the damaged area and paint it again. In addition, drywall can support indoor optimal humidity, absorbing excess moisture and back releasing it when the humidity level is at environment insufficient.

However, if the humidity in the room exceeds 75%, then the drywall may swell, losing its original characteristics. In addition, when choosing plasterboard for finishing slopes on windows, prepare for such negative aspects. This material has relatively low strength, and the created slope can be damaged as a result of mechanical stress. The slopes created require over time additional repairs, or rather, painting, as stains appear on the drywall.

Fixation of sheets of material is carried out on wooden or metal sheathing(if the wall on which the window is located will be covered with plasterboard), with mounting foam (if the putty does not adhere well), with appropriate glue or putty. The last method is the most common.

After installing the window, you need to cut off the excess foam and remove the old trim. Don't forget to also prime the surface. If large potholes and cracks are present, they should be leveled plaster mortar. To avoid penetration of moisture into the drywall and prevent the occurrence of mold, it is recommended to impregnate it with a moisture-resistant compound before assembling the slope.

Then cut the drywall. The sheet is clearly marked taken sizes from a window or door opening, which are removed according to the width of the part that will be sheathed and the height of the opening. A correctly marked sheet of drywall is cut with a special knife, then the finished panels are tried on in size, the entrance to starting line and slope from frame to wall.

The slope is assembled starting from the top panel. First of all, glue is applied to the edge of the panel. The glue is applied in a single strip, a couple of centimeters wide. Next, the panel is installed in the starting strip, pushed in more tightly, and the second edge of the drywall sheet is pressed against the wall. The same is done with the side panels, which are inserted into the grooves and pressed against the wall with glue. All joints must be treated with a neutral sealant.

To prevent premature wear of the corner when finishing door slopes, you can use painting corners made of galvanized steel or aluminum. In places where the drywall fits into the window profiles, it is recommended to stick mesh tape to prevent cracks from forming there. After this, the surface is prepared for painting: apply 2-3 layers of putty and rub it last layer. Drywall can be painted with oil or acrylic paint any color.

Installation of plastic slopes

The most universal type of slopes are plastic ones, the structures of which use mineral wool, which gives the slope hydro- and thermal insulation. Plastic is very durable material, which can last approximately 15-20 years. Now it’s worth considering the reasons why it is rational to install plastic slopes:

1. Plastic slopes can be installed on the same day when you installed new doors and windows, and lining openings with plaster, drying it and painting it takes several days.
2. PVC slopes additionally act as a heat-insulating barrier between the street and the room.
3. Plastic openings have high moisture resistance, great strength and rigidity, they do not fade, do not fog, and are also easy to clean.
4. The material of such panels corresponds to the material from which the double-glazed window is made, so they expand at the same temperature changes, and excessive stress does not occur in the slopes.
5. Plastic slopes do not require extra work by color.
6. Door and window openings get an attractive finished look because they fit well with modern door and window designs.

Sandwich panels

Currently, when finishing slopes with plastic with your own hands, two products have become widespread: plastic Wall panels and sandwich panels. Sandwich panels consist of 2 sheets of plastic, between them there is a layer of foamed or extruded polystyrene. Available in thicknesses of about 8 - 36 millimeters. When facing a window slope, it is best to use panels that are 1 centimeter thick.

Sandwich panels can be used to cover wooden or plastic doors and windows whose width is 5 - 150 centimeters. The advantage of such panels is obvious: in principle, the slopes do not need to be insulated, since the thermal insulation material is incorporated into the panel design. The disadvantage is that the sandwich panel may delaminate when exposed to moisture.

It is recommended to postpone the installation of such slopes until the next day so that the mounting foam has time to dry completely. To provide the best insulation characteristics, slopes must be installed simultaneously with window sills. There are several methods for fixing sandwich panels to the wall, but it is recommended to use the most common and practical of them.

The ends of the panels are secured with dowels to the base of the slope, then fasteners and plastic decorative corners are installed. All seams connecting sandwich panels to window sills, windows and door frames should be treated with PVC-based glue or neutral sealant. Unlike silicone sealants They do not have a sticky consistency; as a result, they do not become dirty or turn yellow.

Wall panels

Plastic wall panels are a less expensive facing material than their sandwich counterparts. Plastic panels are colored or white hollow panels, inside of which there are stiffening ribs located across the sheet. The thickness of such wall panels is approximately 1 centimeter, width - 25, 39 and 37.5 centimeters, length - 3 or 2.7 meters.

It is recommended to use such wall panels when the depth of slopes in houses is up to 25 centimeters, because with wider openings it will be difficult to achieve sufficient rigidity and strength of the coating. When facing slopes with such panels, it is imperative to create insulation from polyurethane foam or basalt wool. Don't forget to cover the joints with a decorative corner.

Plastic wall panels come in glossy and matte finishes. Matte products are used more often, as they do not glare in the sun and look less pompous. It is also possible to find slabs in a “wood-like” version in various shades, which allows you to finish slopes in wooden house in full accordance with the interior design.

Finishing slopes with decorative stone

In the interior, natural stone, be it granite, marble or onyx, is used quite rarely, since it is expensive and weighs a lot, which causes problems with transportation and installation, because not every wall can withstand the weight of such cladding. Therefore, its place is gradually being replaced by light and inexpensive decorative (artificial) stone. This material goes well with wood, so it is often used for finishing windows and door slopes.

The composition of decorative stone for cladding includes cement or gypsum, various dyes and fillers. Perlite, expanded clay and pumice are used as fillers, so the weight of decorative stone is approximately 2 times less than the weight of natural stone. And if you compare it with granite, the difference will be even more significant: artificial stone is 3-4 times lighter than natural stone.

But at the same time, decorative stone is practically no different in appearance from natural stone, successfully imitating it. It can look like a brick, it can be “chipped” - one that has a knocked down texture and uneven edges, as if finished with a jackhammer. Sawn decorative stone with smooth, even edges is also on sale. Rubble stones resemble natural boulders of different shapes and sizes.

Finishing door slopes with stone can be done independently, since for cladding there is no need to perfectly level the surface, which means there will be no labor-intensive work. For interior decoration it is recommended to choose decorative tiles, which have a thickness of 1.5 - 2 centimeters, and which are painted over the entire thickness, since in the event of a chip the defects will not be noticeable.

The presence of a textured side on the tile allows it to be attached to any surface, and special rounded and corner elements allow you to create complex designs on slopes and openings. Therefore, preparing the surface for installation of decorative stone will not take much of your time. Do on smooth surface notches to ensure high adhesion of the stone plates to the glue, and then prime the surface of the slope. After this, glue is applied to the surface of the walls or the adhesive base using a spatula-comb.

Decorative stone is laid in even horizontal rows and adheres perfectly to the surface liquid nails. Align the plates using a level. If you need to trim platinum, you should do this: when the main component of the material is gypsum, you can use a hacksaw for trimming, and if the base is cement, you should use an electric circular saw.

The last stage of finishing the slopes decorative stone is the grouting of the joints when the glue has finally set. It is customary to seal the seams the next day, filling them special solution and smoothing with a rubber spatula. You can also lay artificial stone end-to-end without seams.

Metal finishing of external slopes

External slopes perform several functions. The very first consists of decorative concealment of UV-sensitive polyurethane foam. Properly finished external slopes of window structures reliably protect assembly seams from the harmful effects of moisture. Water that gets into the polyurethane foam worsens its thermal insulation qualities and causes destruction of the material due to constant freezing and thawing, as well as expansion during freezing.

There are a lot of technologies for finishing external window slopes. The most popular option is plastering, but this method has many disadvantages. No matter what you do, a crack will inevitably appear between the window frame and the slope. Usage plastic slopes not practical for exterior decoration: plastic when low temperatures becomes fragile, and this is completely unsuitable for our conditions.

Therefore it is worth paying attention to metal slopes, which were invented back in Soviet times. The main advantages of external slopes made of metal with a polymer coating are as follows. They increase the thermal insulation properties of the window seam, perfectly protect houses and apartments from freezing and blowing, do not rust, do not change their shape over time, and retain their color.

The only significant drawback of finishing external slopes with polymer-coated metal is the high cost. However, this is more than compensated for by the long-term operation of the products without the need for repairs. You do not need to plaster, whitewash, paint or finish metal slopes yourself every year, which allows you to significantly save on finishing materials.

Thus, it becomes clear that slopes need to be made immediately after installing the window structure. At most, you can postpone this activity until the renovation of the apartment is completed. Much will depend on the selected materials and the quality of the installation of the double-glazed window. Properly lined window openings will not freeze and get wet, as a result of which they collapse, peel off and become covered with cracks.

Hide

After installing plastic windows, the question always arises about the design of the slopes. After all, they perform not only an aesthetic function, but also provide additional heat, sound and moisture insulation. Experts say that designing slopes is a complex and expensive process. In this regard, many are interested in interesting ways and options for slopes on plastic windows.

There are several technologies for installing slopes on windows or the so-called<окосячки>. This includes plasterboard covering, installation of sandwich panels, plastering and finishing with PVC panels. Let's take a closer look at these types.

Sheath better than plasterboard With increased stability to moisture - gypsum plasterboard. There are two ways to cover window slopes with plasterboard yourself: framed and frameless.

Moisture-resistant drywall.

Frame installation method

At the line where the plasterboard joins, a profile is screwed into the groove using self-tapping screws. The frame is ready, installation can begin. The design of window slopes has such a feature that there is empty space between the gypsum board sheet and the wall, this will worsen the thermal insulation qualities of the opening. Therefore, the space is filled with mineral wool or polyurethane foam.

When using polyurethane foam, you should fill the space carefully, because... When drying, the foam tends to increase in volume and can damage drywall.

At the junction plasterboard sheets install a perforated corner and putty on top of it.

Frameless installation method

Basically, the frameless method is used for covering old plasterboards. Before starting work, the surfaces must be cleaned of finishing materials and primed. The plasterboard is cut and prepared in advance, then glue is applied pointwise to the blanks and they are attached to the guide.

For fixing drywall and uniform distribution glue, you should press it with a wooden block, this will give the structure evenness

For additional fixation, use spacers installed to. Complete fixation of the gypsum solution (Rovband or similar) occurs within an hour. Once the covering is complete, they begin to putty and paint; you can also paste over wallpaper.

This is the most common and quite practical method for do-it-yourself windows. Typically, sandwich panels with a thickness of 10 mm are used. They are distinguished by their budget cost, along with high moisture resistance. The surface can be glossy, matte, or stylized as wood. They have a spongy structure, which provides thermal insulation.

Sandwich panels

Another technology for installing slopes is to install wooden block and secure it using self-tapping screws.

Advantage of this method is that using wooden slats it’s faster and easier to align crooked corners, and uneven areas between the rail and the wall are filled with mounting foam or gypsum mortar. This method allows you to quickly install window slopes with curvature walls

Minus visual, then even with small sizes the bar will have to use a corner of at least 30mm. In addition, when attaching the rail, the corner breaks off.

Fastening is carried out on polyurethane foam. Sandwich panels are placed tightly on the box from the window and foamed, and the other edge is attached to a wooden sheathing. The outer edges of the sandwich panels are secured with screws. The edges where the screws are screwed in will close.

Treat joints and cracks with sealant.

Plastering window openings

This method is the most labor-intensive and requires extreme accuracy, but the least expensive. Mixtures for plaster are based on gypsum and cement. Before use dilute with water.

Technology of work execution

Before starting plastering, all working surface carefully prepared. If there are strong unevennesses, then the entire wall is knocked down and primed. First they plaster the walls, and only then they start working with. This is a very long process, because one layer must dry before the second can be applied. The gaps are filled with polyurethane foam, this provides additional sound insulation. Each layer of coating - base must be primed. Corners are finished with special plaster corners, which ensure the evenness of the corner.

In order to avoid cracks in the future where the plastic comes into contact with the plaster, acrylic sealant is applied to the corners of the box joints, which can be easily painted.

How to make slopes on plastic windows

To install you will need:

• Plastic panel, they come in three and six meters;
• Starting profile, the same dimensions as the panel;
• Profile F – shaped, for edging a window opening;
• Mineral wool, for insulation;
• "Liquid nails" with a gun,
• Metal screws for attaching profiles to the frame and window sill.

The work is performed in several stages:

1. All cracks are sealed with white silicone sealant.

Warm slopes on the windows in winter will prevent the formation of condensation and, accordingly, the appearance of harmful fungi.

Installing slopes for plastic windows with your own hands is the right way save. Because sometimes in companies this process is expensive and not every company undertakes to carry it out.

If you take the correct measurements and select all the necessary components, making slopes on the windows with your own hands will not be a difficult task for you.

The design of PVC windows after their installation includes finishing of the slopes. After completion of this work, the corners are drawn up decorative corners or install internal slopes on windows.

Why do you need window treatments?

The interior decoration of plastic windows has not only a decorative function, but also a protective one. The installation seam must be reliably protected from the influences exerted on it so that the window system as a whole functions correctly: the glass does not fog up or freeze, and condensation does not accumulate on the slopes.

The installation seam on the outside must also be reliably protected from the effects of precipitation, wind and sun rays, under the influence of which expanded polystyrene is destroyed. You can effectively protect it by installing metal slopes and trims on plastic windows for exterior decoration, which will give the window a neat, finished look.

Material used for interior decoration of window openings in a house different types. This could be decorative plaster, do-it-yourself installation of PVC panels or drywall on the slopes of plastic windows. The decoration of internal slopes with decorative looks impressive artificial stone. To understand which of these methods is better, it is worth considering each of them separately.

Decorative plaster

When carrying out renovations in a house, interior decorative plaster is often used as a finishing material for walls. This material will make the slopes on the windows unusual and spectacular.

Decorative plaster is often used for interior decoration of slopes

Part decorative plaster may contain fillers of various fractions and origins - these can be natural fibers wood or stone chips or artificial granules of various sizes. Decorative plaster is used as a finishing layer, creating an unusual textured surface or an intricate design, like Venetian plaster.

As a material for interior finishing of slopes, decorative plaster has the following characteristics:

• effectively masks base unevenness;
• it can be applied to any base material: brick, concrete, plasterboard, wood;
• this material does not absorb odors;
• safe, non-flammable and environmentally friendly composite;
• has soundproofing qualities;
• in case of minor defects in the base, preliminary repairs are not required;
• when waxing or painting plaster layer becomes water-repellent;
• has breathability;
• Repairing the plaster layer is very simple, there is no need to remove all the finishing;
  finishing of arched window structures is possible.

Types of decorative plasters

Depending on the type of filler and main substance, decorative plasters are:

Surface preparation

The durability of the plaster layer depends on a well-prepared surface.. Therefore, finishing window slopes inside with decorative plaster should begin with preparing the base.

Drywall slopes

Finishing slopes with plasterboard is quick and does not require special construction skills. Installation is possible using polyurethane foam or putty as an adhesive or on metal carcass . Drywall for windows must be marked GKLV.

Drywall on slopes can be mounted on a metal frame

It is characterized by the following positive qualities:

• environmental friendliness;
• affordable price;
• simple installation;
• decorative effect when finishing with any materials;
• smooth, durable surface;
• durability;
• possibility of designing arched openings.

Preparatory work

Surface preparation consists of the following steps:

Using polyurethane foam, you can finish a window opening without having any construction skills. It is important to remember that drywall is fragile material, therefore, the necessary parts must be cut out of it carefully, without any effort.

To get smooth edges at the cut points, you need to follow the drawn line on a sheet of drywall, applying a ruler, using a sharp construction knife make the cut. You need to cut the top paper layer and a little inside. Then you can lightly tap along the cut - the drywall will break itself along the intended line.

Foam mounting

Finishing slopes with plastic panels

Finishing of window slopes inside can be done using ceiling plastic panels or multilayer sandwich panels. The installation of this material is so simple that it is possible to finish the inside of plastic windows with your own hands. How to make slopes for plastic windows in a house will be described below.

PVC panels are most often used to finish slopes from the inside.

Sandwich panels are better than ceiling panels due to the presence of a layer of insulation inside. However, ceilings also have thermal insulation properties due to air chambers between internal stiffeners.

Installation and repair of slopes inside a building using these finishing materials is possible due to their qualities:

• PVC slopes are durable;
• the use of panels for finishing window slopes gives them an attractive, neat appearance;
• finishing options can be very diverse thanks to a wide range of colors,
• which have external surfaces of panels;
• it is possible to install plastic on arched structures;
• Repairing plastic slopes is not difficult;
• ease of installation - window openings are finished with your own hands, and installation does not take much time;
• PVC is easy to process;
• slopes lined with plastic on the inside are easy to maintain;
• finishing window openings this material increases the energy efficiency of the window system;
• The interior decoration of windows prevents them from fogging and freezing.

Installation

How to install internal slopes for windows made of PVC panels is shown below.

• remove excess polyurethane foam using a stationery or construction knife;

  To remove residual foam, use a stationery or construction knife

• We fix a wooden block along the perimeter of the window opening near the frame using self-tapping screws;

  Secure a wooden block around the perimeter of the frame

• We attach the starting profile to the block;

  The starting profile is attached to the block

• We install a strip along the outer perimeter of the window;

  The rail is fixed along the outer perimeter of the frame

• It’s better to insert the side elements first;

  Side panels install first

• then insert the top panel, bend it, foam it a little and fix it in the required position;

  A small layer of foam is blown between the upper slope and the PVC panel

• fix the side parts in the same way;
• After the structure has dried, the corner parts are decorated with decorative elements - corners or platbands.

  Corners are covered with platbands

Sandwich panels can be installed in the same way or without starting profile. In this case, the panel is placed in a groove cut in the mounting foam. This installation method is relevant when it is not possible to place the block around the perimeter of the window frame.

Platbands

Platbands or casing for internal slopes for PVC windows can be executed from different materials, but her functional purpose one thing - protecting the installation seam from destruction and giving the window opening an aesthetic appearance.

Types of platbands

Platbands differ from each other appearance and functionality:

Flat platbands. This is the easiest to perform and inexpensive type cashing out.
Profiled platbands have a convex surface different profiles aimed at strengthening decorative function cashing out.
Shaped platbands can have a complex relief and imitate natural wood.
Carved platband is the most expensive type of cash, made to order according to individual sizes.

Materials for production

The most common material for making cash is sheet plastic. It is used for the manufacture of budget flat platbands, which can be used for finishing windows indoors and outdoors.

This material is not afraid of temperature changes, exposure to moisture or sunlight. Its surface can be laminated and take on any color or imitate various types of natural wood. Therefore, choosing cash to match the color of the window facade will not be difficult.

Plastic cash can be made to match any façade

Plastic platbands are not prone to deformation due to temperature changes and exposure to moisture.

Profiled PVC trims have the same properties, but may have a shaped surface. They are also used for interior and exterior window decoration.

MDF trim can also be flat or profiled, but they are used exclusively indoors, since the properties of MDF do not allow their use on outdoors under the influence of surrounding natural phenomena.

For external use, dense foam casing can be used. This material is easy to process and install. You can cut out the most intricate and intricate designs from polystyrene foam. complex shapes. It can be decorated with any finishing materials. It has negligible weight, so it does not put any load on the wall.

Foam trim can be used for exterior window decoration

The most expensive window design option is the installation of wooden carved cash. Carving can be done manually or mechanized. Handmade is very expensive due to its individuality and exclusivity.

Profiled and shaped frames made of natural wood, made on a machine, will cost less.

Behind wooden platbands careful care is required, since wood, when used in conditions of exposure external environment, there are some disadvantages:

• wood can become deformed when absorbing moisture or crack as a result of drying out;
• Such cashing looks harmonious on wooden windows or on timber facades. On modern facades Such cashing out will look ridiculous.

Fastening

Most often, when installing platbands on a plastic window, mounting elements are used that are fixed to the frame or wall.
