Installation plastic windows this is not always accompanied by finishing of the slopes by representatives of the window company. However, this is understandable - if you do it wisely, the process may take several days. So it will be much better if you do this work yourself. Don't know how to properly make slopes on windows? No problem, let's learn together.
How to choose material for window slopes - looking for options
The functions of window slopes are reduced to protecting the window opening from moisture, as well as providing insulation and noise reduction. Without slopes even the most best windows will not be able to perform their functions efficiently; their absence may lead to serious problems in the future. Therefore, when choosing windows, think in advance about how to properly make slopes and what material to choose for this.
The general requirements are:
- Durability and reliability;
- Resistance to weather conditions, typical for your region;
- Sealing and environmental friendliness;
- Thermal insulation and sound insulation of premises;
- Ease of cleaning.
Wood finishing is very effective way, which goes well with wooden windows. However, such products require considerable costs and very careful care. The question of how to properly make slopes on wooden windows should only be dealt with by specialists, but it’s worth it - this is an elite slope covering.
Plastic slopes have become widespread along with plastic windows. In many ways this is the most best option: you get a neat, clean surface, which is quickly installed, easy to clean and retains heat very well. Even at frosty temperatures outside the window correct installation slopes, condensation on the elements themselves and on the adjacent section of the wall is eliminated. However, the impact of moisture on the plastic slopes themselves does not threaten them. Over time, plastic parts may turn yellow - this is perhaps the only drawback of the material.
Plastering slopes - how is it done?
It is worth using this method of finishing a window opening only during overhaul when the wall covering changes. In progress cosmetic repairs It is better to change the plaster for something less easily soiled - you will definitely ruin the wallpaper. It should be noted that this method is the most time-consuming.
Before making slopes on the windows, it is necessary to clean the surface of the old coating and install beacons - wooden or metal. There are also ready-made plaster beacons, which are ideal for beginners. So, the first mark is placed in close proximity to the window block, indicating a layer of plaster of at least 5 cm. Then the beacons are placed at the corners of the opening frame and leveled using a level.
For internal window slopes, dry is best suited. cement-gypsum plaster. This solution dries faster, which is important for saving time; moreover, it can be applied in a thicker layer than the same cement-sand composition. It is necessary to mix the solution construction mixer, or use a hammer drill or drill with a special attachment at low speeds.
For external slopes nessesary to use cement mixture or special façade putty– both materials adequately withstand exposure to moisture and other atmospheric phenomena. Before plastering, it would not hurt to carry out thermal insulation, especially if the windows are plastic - this will avoid fogging of the windows in cold seasons.
The plaster is applied in several passes - each layer requires drying. The first step is to spray - dilute the plaster with a large amount of water and spray the area to be finished with an ordinary broom soaked in the solution. This allows you to get good adhesion between the base and the plaster layer. The second layer should rid the surface of minor irregularities, no more - it is strictly forbidden to apply a thick layer of plaster.
The next layer is applied after the first has dried and primed. The last layer Apply finishing putty, which is sanded after drying. The gaps remaining at the junction of the window block and the putty should be sealed with a special sealant that can be painted. For high-quality sealing, the joint is cut at an angle of 45° by 2-3 mm, the resulting recess is primed and after a few hours is filled with a sealing compound.
The finished surface should be primed to prevent the appearance of small cracks and prepare it for painting. Usually enamel or acrylic paint, which are applied in two layers. In total, it will take about a week to complete this set of works from the beginning until the last layer of paint dries.
How to make window slopes from plasterboard - instructions for beginners
Drywall has one significant advantage over the same plastic - it can be repaired with minor damage and return a clean, aesthetic appearance. No special skills are required to create a slope from plasterboard. First you need to create a frame from a galvanized profile - some window companies They supply these complete with their products. In any case, a special groove must be provided in the window block, and the profile can be purchased separately.
The installation of slopes should begin no earlier than one day after installing the windows - during this time the polyurethane foam will completely polymerize, and its excess can be cut off and the spacers removed. The guide profile is screwed along the line where the drywall joins window block self-tapping screws.
Insulation is laid between the profiles, and then drywall is mounted to the frame. When it is installed, it is sanded and the gaps and irregularities are smoothed out with putty, and only after that they begin to treat with primer. The corners of the drywall should be protected with a galvanized metal profile, which will protect them from delamination. As with plastering, joints window frame and the finished slope is sealed with acrylic putty. It will harden in no less than 12 hours, and only after that the slopes can be painted.
After you have your windows installed, finishing the slopes becomes a necessary and final step. For new windows, I want to choose the most practical and durable type of finishing for the window opening, namely. And this is not surprising, since correct installation, window profile and the slopes are continuously interconnected. And if any of this component is not performed correctly, then the problem can spread to both the window and the slopes. For example: you have installed quality windows, good manufacturer, but the slopes were made of poor quality. As a result, you get condensation on the windows, blowing and other unpleasant consequences. Therefore, carefully select the material for the slopes and a qualified installation team.
The Teplovik company produces slope finishing using materials such as plastic sandwich panels and plasterboard. If you choose between these completely different types window trim, then it is difficult to get a clear answer as to whether plastic or plasterboard slopes are better. Each of these types of slopes has its own advantages.
Plastic slopes made of sandwich panels have the following properties:
Visual similarity with PVC windows - they are often called logical conclusion plastic windows, as they consist of a plastic sheet.
Insulation is the only material that has in its structure a layer of extruded polystyrene foam insulation.
They do not require modification - they do not need to be tinted over time; the service life of such slopes can be compared with the service life of plastic windows.
Easy to use - this type of slopes can be washed with any detergent.
Installed only at slope depths up to 500 mm.
Have the following characteristics:
Versatility - this type of slopes is suitable for any windows (wooden, plastic, aluminum).
Installed at any depth of the slope - the only type of slopes that has no size restrictions; it can be installed at any depth of the window opening.
Painting – require updating the paint over time.
They do not have an insulation layer - the plasterboard for the slopes itself is 12 mm wide, but if necessary, the window opening can be insulated.
As you can see, these slopes are completely different in their characteristics, they have a number of advantages that play a significant role when choosing finishing material. But when it comes to plastic windows, it is better to opt for a plastic sandwich panel. were created for PVC windows and, due to related material, are their continuation. Pay attention to the insulation layer, which has thermal insulation characteristics, i.e. it does not release heat. If you have wooden windows, then . This type of finishing will highlight the beauty of a wooden window frame and give the window opening a classic look. It is worth noting that with proper installation, plasterboard slopes can be quite warm; the main thing is to entrust this process to professionals.
So which is better? Plastic slopes or plasterboard? There is no definite answer, but if we consider it from the point of view of ease of installation, warmth and practicality, then of course slopes and plastic sandwich panels are better than slopes made of plasterboard. But if we take into account the slopes custom size and shapes, wooden or laminated window profile, then here the advantages can be given to plasterboard slopes.
The Teplovik company offers to install plastic slopes and plasterboard the next day after placing your order. Call the numbers listed on our website.
In this article we propose to talk about what exist methods of finishing slopes for plastic windows. Let's look at the pros and cons of one method or another and analyze which finishing method is best to choose.
Installation of slopes is a complex of construction and finishing works, without which the window will be able to perform the functions prescribed by the manufacturers. Slopes are finished using various technologies, characterized by quality, durability and price.
In order to do suitable choice, you need to consider a few tips
- The slope must be reliable and durable;
- Resistance to weather influences - moisture, heat, temperature changes is very important;
- You should pay attention to the tightness and environmental friendliness of window frames and slopes;
- Windows with slopes must successfully cope with the thermal insulation of the room and sound insulation;
- Slopes must have long term service commensurate with the window profile, and be resistant to wet cleaning.
Let's look at what slopes there are and what are their differences:
- a widely used method suitable for both internal and external slopes in houses of any type. Plaster is the simplest and most cheap option. At low temperatures, there is a possibility of the slope freezing due to the weak thermal insulating properties of the plaster, which leads to the formation of condensation and mold.

smooth and strong slopes, can be repainted
—
you need to have certain skills in working with plaster, there is a possibility of the slope freezing
. Drywall is an excellent thermal insulator and rigid material. It costs more than plaster, but cheaper than plastic. However, after installing the drywall, the window opening must be properly treated with a primer and then painted.
+
you can make the slopes smooth without having the skills, you can repaint
—
not very durable; if wet for a long time, drywall can swell
Wooden slopes go well with wooden windows; both are quite expensive and require special care. Install wooden slopes only professionals should, it is extremely difficult, but appearance The windows with them become simply royal.
+
beautiful appearance, environmentally friendly materials
—
you need to have certain skills in working with plaster, high cost
Plastic window slope Its characteristics best match a plastic window. Plastic slopes are used indoors various types. They have a neat and pleasant appearance and are quickly installed. The main advantage of this solution is that plastic slopes, due to the closed porous structure of the inner layer, have a low heat transfer coefficient. Therefore, at low outside temperatures, condensation on slopes and on adjacent window elements, where the wall cross-section is minimal, is excluded.
+
decorative properties, moisture resistant
—
almost irreparable if damaged, may turn yellow over time
Thanks to the above criteria and having additionally decided on the budget allocated for the installation of windows and slopes, you can choose the optimal window finishing option.
The installation of practical and beautiful plastic windows is accompanied by the need to finish the slopes, which provide the window opening with better thermal insulation and give a complete look. The choice of building materials and technology for finishing slopes depends on a number of factors: the tightness of the material, resistance to moisture and temperature changes, appearance (compatibility with the interior of the room), cost.
The most practical and popular materials for finishing the slopes of plastic windows today are plasterboard and plastic sandwich panels. Let's look at the positive and negative aspects of using each of them.
Drywall slope
Drywall, consisting of two sheets of cardboard with gypsum filler inside, is an environmentally friendly safe material. To install window slopes, moisture-resistant plasterboard is used.
Mounted in two ways: framed and frameless. Frameless method used on smooth slopes and involves installing the material using mounting adhesive. Frame method used on uneven surfaces of slopes.
Drywall is attached to wooden beam or on a structure made of metal profiles (pre-installed with dowels). To improve thermal insulation, it is advisable to insulate plasterboard slopes polyurethane foam or mineral wool. After installing the slopes, the seams and surface irregularities are sanded and treated with sealant, and the outer end part along the perimeter is closed with a corner. Final stage- painting or wallpapering.
Advantages of plasterboard slopes:
1. The material is durable and, with proper care, can last up to 20-25 years.
2. A slope made of plasterboard has good thermal insulation qualities (especially in combination with foam or mineral wool).
3. Unlike other materials, all kinds of defects (scratches, dents from impact and any surface contamination) can be easily eliminated on plasterboard.
4. Relatively not high price.
Disadvantages of plasterboard slopes:
1. Low moisture resistance of the material. Using drywall in areas with high humidity will result in the need to periodically repair and paint the surface.
2. Difficulty in installation. Installing plasterboard slopes takes a lot of time. In addition, cutting and adjusting the material will lead to the formation large quantity dust and debris in the apartment.
Slope made of plastic sandwich panels
The sandwich panel, due to its structure (plastic, polystyrene foam insulation and moisture-resistant PVC), is an excellent thermal insulation material. It has a quality certificate and is safe for human health.
Most often, the installation of panels is carried out simultaneously with the installation of the window. To do this, it is enough to precisely cut the material and insert it inside a pre-established starting profile. The sandwich panels are attached to the slopes using mounting adhesive. The end part around the perimeter is closed at the top F-shaped profile. Thus, the installation procedure is completed.
Advantages of slopes made of sandwich panels:
1. Specifications the panels provide the slopes with durability and excellent thermal insulation; there is no need for additional insulation.
2. Unlike other materials, sandwich panels do not require processing or painting after installation. The color matches the color of the window frame.
3. The panels are resistant to temperature changes and high humidity, making them easy to care for (for example, wash with detergents).
4. Fast and clean (compared to plasterboard) installation.
Disadvantages of slopes made of sandwich panels:
1. The main disadvantage of the material is that if the panel surface is damaged, the defect (pothole, deep scratch) cannot be quietly eliminated. As a result, the entire panel will have to be replaced.
In addition, these panels are quite soft and are easily pressed, for example, by blinds fittings when opening a window.
2. The price of some models of sandwich panels can significantly exceed the cost of other materials (for example, drywall).
Which slope finish should I choose?
We usually make our choice taking into account proposals from professionals who will supply and install windows, including price proposals. For example, you can find out about plastic windows from a manufacturer in St. Petersburg from representatives of the StroyKomfort company. But in principle, you can decide on the option for finishing the slopes even before calling the experts, taking into account the above-mentioned properties of the materials. First of all, for this you need to know:
Type of premises (residential, commercial, special purpose). So, in a room exposed to large differences temperatures and high humidity, drywall should not be installed.
Dimensions and characteristics of the window opening. Usually in heavily damaged window opening do plasterboard finishing slopes.
Contamination of the premises, i.e. the possibility of wet cleaning slopes.
In any case, no matter what material you choose, the main thing is to produce high-quality installation the slopes themselves. Not only the appearance of the room, but also the tightness of the window opening and the thermal insulation of the entire room will depend on this.
The final stage of the installation process of modern double-glazed windows is the finishing of the slopes. They are needed not only for decorating a window opening. Thick double-glazed windows and reliable fittings provide excellent thermal insulation, but the interface between the window frame and the apartment wall remains the weak point of the structure. This problem area needs to be covered. Let's find out which slopes are best suited for plastic windows.
Before considering window framing options, their advantages and disadvantages, let’s determine what is required of these elements.
- Not inferior to the durability of the window design. Modern double-glazed windows are designed for a minimum of 15–20 years of operation. Slopes must withstand no less time without loss of basic qualities. Few people would like to redo them every two or three years.
- Comply with the general style of the window, forming a single whole with it.
- Maintain or even improve the performance characteristics of plastic windows.
When renovating an apartment in a new building or replacing windows, you will have to choose how to finish the openings after installation modern designs with double glazed windows.
Window slopes can be finished using the following materials:
The manufacturing technology consists of sequential application of several layers of plaster and putty mortar. Layer finishing putty painted.
Finishing a window opening with plaster has the following advantages:
- Versatility. This material is used in rooms with different humidity and temperature levels.
- Reasonable price. Plaster – inexpensive material Moreover, it is possible to save money by doing the work yourself.
- Strength. Plaster slopes more resistant to mechanical stress compared to other types of finishes.
- No seams. Perhaps the main argument of supporters of such a coating is that there is no need to additionally process the joints and interfaces of the opening planes.
- Possibility of updating and repair.
But a number of serious shortcomings have led to the fact that plaster is used less and less for work of this kind:
- Duration and complexity of the process. Finishing takes considerable time: each layer plaster mixture need to dry out.
- A large amount of dust and dirt, risk of scratching the window.
- Low thermal insulation properties of plaster. Such slopes are prone to freezing in winter and condensation. In addition, when installing them, you have to cut the foam one or two centimeters inward, weakening the thermal insulation seam.
- Detachment from frame. It is impossible to firmly connect the plaster and the PVC frame. There are no sealants with equally good adhesion to both materials. This leads to the formation of cracks between the window block and the plaster layer.
The last two drawbacks can be eliminated by insulating the opening with penoplex before plastering and using an adjacent window profile with reinforcing mesh.
Pieces of gypsum plasterboard are used for their manufacture. the right size, which are screwed to the profile frame or glued to the sides of the opening. Then the surface of the drywall is primed, puttied and painted. The space between the wall and the new slopes is insulated with polyurethane foam.
Attaching gypsum boards is easier and faster than creating a flat surface with plaster. But we must not forget that after installation, finishing is required, which will take several days.
Advantages of using drywall:
- Low cost.
- Easy to install. Requires very basic construction skills.
- The ability to easily create perfectly smooth surfaces.
- Additional insulation.
- Simple repair, suitable for repeated repainting.
- Inability to firmly bind the slope material and the PVC frame (as with the plaster version). This leads to the appearance of cracks at the joints.
- Fear of moisture. If the windows “cry”, under the influence of condensation the drywall, even moisture-resistant, gradually collapses and swells near the frame. Judging by the reviews, this main reason refusal to use gypsum boards in the manufacture of slopes.
- Risk of sagging and squeezing. Still, drywall is a fairly fragile material.
To avoid the stage finishing, you can take laminated gypsum board instead of the usual one. But in this case, you will have to use special corners to cover the ends of the sheets.
The technology for installing slopes made of gypsum fiber boards is practically no different from attaching plasterboard; the advantages will be the same. At the same time, GVL does not have the disadvantages of GCR: it is much stronger and stiffer, and its moisture-resistant version is not at all afraid of a wet environment.
Mr. Build believes that when correct installation GVL slopes are superior to other options in terms of performance and appearance.
Advantages of gypsum fiber slopes:
- Fairly simple installation.
- High strength and rigidity.
- Possibility of high-quality insulation.
- Ideal design geometry.
- Long service life - at least 10 years.
- Maintainability: a damaged element can be easily puttied and tinted.
- Moisture resistance.
- Relatively high price (compared to gypsum board and plastic).
- The need for finishing.
- Cutting gypsum fiber is somewhat more difficult than cutting drywall.
If, after priming and puttying, you paint slopes made of high-quality gypsum plasterboard latex paint, then they can be washed without fear. And repainting will be required no earlier than after 5–8 years.
Another way to get aesthetic and reliable slopes is to cover the opening with double-sided sandwich panels. They not only have good thermal insulation properties, but also with sufficient rigidity.
It is not recommended to use one-sided sandwich panels and decorative panels for finishing a window opening. Wall panels made of thin cellular plastic. They do not have the necessary strength, wear resistance and thermal insulation qualities.
Plastic finishing is gaining increasing popularity. The material of the slopes not only visually harmonizes with window frame made of PVC, but is also securely fastened to it using special sealants. This method of finishing the opening has other advantages:
- Low price.
- Smooth surface that retains its properties on long years and does not require additional finishing or regular maintenance.
- No cracks or temperature changes due to the use of the same material from which the frame is made.
- Additional thermal insulation, enhancing weakness window opening - a seam between the frame and the wall of the room.
- Fast installation. Plastic slopes are installed faster than plasterboard and especially plaster ones.
- Minimum amount of dirt and dust when facing with plastic.
- 100% moisture resistant.
- It is possible to replace part of the slope if damaged.
- The frame covering the outer contour reliably protects the junction of the wallpaper and the window opening.
- Susceptibility to mechanical damage.
- Impossibility of local repairs. If it breaks, you will have to replace the entire panel.
- Low quality of additional elements, such as corners. Often these small parts are made from recycled plastic, which turns yellow over time and stands out unattractively against the background of snow-white slopes.
- Incompatible with interior. Glossy plastic will look unnatural in a room decorated in classic style, as well as in any other direction of design where natural materials are used.
To avoid adding others to these disadvantages of plastic slopes, you need to choose the material wisely, guided by two main rules:
- Panels must be made from virgin plastic. Only such products are absolutely harmless even when heated in the sun and will not turn yellow after a year.
- The PVC layer must be thick enough. This will help avoid damage to the slopes.
When choosing between matte and glossy plastic, you need to take into account that stains and fingerprints are more visible on a glossy surface. Matte panels look more natural and are similar to classic painted slopes.
All slope finishing options have pros and cons. No ideal material, which would be better than the others in every respect. Therefore, when choosing, you need to decide which properties and characteristics are more important in a particular case.
