A sandwich panel is increasingly used, since the material is light in weight, easy to maintain and resistant to stress.
Sandwich panels for the slopes of plastic windows - finishing material, which includes three layers.
Characteristics and features of the material
A pair of layers consists of plastic, the third, the inner layer is insulation. Such panels are used in construction almost everywhere, any work can be done, but there are some differences in the insulation used.
Panel insulation is most often mineral wool. The sandwich structure is ideal to install it on the slope of the window, the material does not allow extraneous noise and cold to pass through, due to which the window will retain heat in the house. The characteristics of the panels do not end there, because mold, fungus does not appear on them, they do not undergo temperature changes. A sandwich panel can be made of different materials, which stands on the outside, for more details in the table:
| Material: | Description: |
|---|---|
| Cink Steel: | Installation of panels is easy, operation is simple. Not used for windows. |
| Aluzinc: | It is extremely rarely used for windows, due to the fact that the view of the window will be spoiled. |
| Drywall: | Suitable for creating panels on slopes. Easy to use, the slopes will look beautiful. |
| Plastisol: | Durable material, since the panels contain special additives that make the panel stronger. Not subject to destruction due to weather conditions, resistant to mechanical damage. The composition is free of toxins, which means that sandwich panels of this type can be installed for window slopes, both inside and outside. |
| Polyvinyl chloride or polypropylene: | Most often used to create a sandwich panel, ideal for window slopes. |
Important! It is convenient to sheathe a window with such material, because PVC panels are produced in different colors, white material or wood imitation is used.
Pros of plastic sandwich panels for window slopes
The main advantage of the panels is 100% moisture resistance, which means that there will be no mold and mildew on the slopes, condensation will not appear on the window. Comparing drywall and a sandwich panel, the plastic sheets are easier to install, the installation process is easy, in addition, there is almost no debris during operation.
The cladding does not require special care, it will be enough to rinse the surface when needed and that's it. Installation work does not require a special tool, a standard set and a knife or jigsaw, which can be used to cut and saw the material, are enough. The expense of funds for the slope is minimal, the cost of the panels is acceptable, given the advantages of the material.

Preparatory work
After dismantling wooden windows and installing metal-plastic ones, it is necessary to prepare the surface for the device of a slope made of sandwich panels. You need to do the work step by step, the instructions for preparation are as follows:
- The wall is coated with an anti-fungal agent.
- The polyurethane foam, which interferes, is cut off; if necessary, the slots can be foamed and then the remaining foam can be cut off.
- The frame is measured, points must be put along the perimeter, retreating from the edge by 5 mm. 2-3 points are drawn on each side. After that, a level is put to them and everything is connected. The lines must be flat.
- The dimensions of the opening at the top and bottom are removed. By the way, during the preparation, you can also insulate the window sill. Insulation will make the house warm and cozy.
The preparation of the slopes from the sandwich panels with your own hands is completed, now you need to install the system on the window.
Installation of slopes from sandwich panels
The installation of window slopes from sandwich panels is correctly carried out as follows:
- A material is being prepared that needs to be lined with a window. In the course of work, the application will require: starting profile, finishing profile, platband, foam, silicone or sealant.
- Further, everything is carefully measured again, the data is transferred to the mount (profile). The profile should be cut to size and then installed along the perimeter of the window with self-tapping screws. The step width is 15-20 cm.
- Now the depth of the slope and other parameters of the elements are taken in order to transfer the data to the panel. The sheathing is cut by the cutting tools.
- All the cracks on the slope must be filled with foam, only after that the installation of the slopes from the sandwich panels begins.
- The panel is placed in the starting profile, it will guide the rest of the slicing. The material is leveled.
- The trim should be fixed with tape or with a support rail.
- Similarly, you should fix the panels around the entire window and stick adhesive tape on them.
- If the gap between the panel and the wall is large, the thickness allows, then the technology provides for the insertion of mineral wool.
- The outer casing is cut to the height of the window and is made slightly longer than the opening, by the width of the casing.
- The plastic casing is put on the panel, in accordance with the dimensions.
- Making the correct angles, for them you will need to cut the upper part of the casing at 45 degrees, and then fasten it at the top. The plastic corner should line up around the edges. The vertical side is made in the same way.
- At the end, the seams are sealed, which will keep street noise and cold, preventing them from entering the house. Silicone is used for this. The platbands themselves should be smeared around the perimeter and glued to the slope.
This completes the finishing of the slopes with sandwich panels. The technical process is presented in detail in the video at the end of the article. A sample of how to trim a window can be found on the Internet in the photo. Installation of PVC sandwich panels for slopes is a simple process, the most convenient and good for people without plastering experience. Knowing the peculiarity of the material and the rules for how to install the slope, you can revet everything yourself.

Now technologies do not stand still and are constantly being improved. One of these innovations is the installation of sandwich panels. Having a sufficient number of advantages, panels are becoming more and more in demand every day, and even an inexperienced beginner can install them.
Material properties
The device of standard panels looks like a sheet, the outer side of which is a one-piece pvc sheet, the inner side is polystyrene sheet, and there is a heater in the middle. That is why this finishing option was called the American word - sandwich panel. They differ only in the material of the facing side, and the installation remains the same for any type.
Important! The people call sandwich slopes - warm slopes. This is due to the insulation that is present in the panel.
When you have already imagined what it is, I will tell you about their advantages:
- Despite their popularity, they remain affordable for everyone due to their reasonable price.
- This is not just a building element, it is also an independent device that has its own complete set.
- The internal space is filled with mineral wool or expanded polystyrene - this indicates the non-combustibility of the structure.
- Excellent performance of thermal insulation, as well as additional sound insulation is achieved with their help.
- This finishing method is durable and durable.
- If you are doing the installation yourself, then you must follow the installation technology exactly. In this case, the resistance to moisture and mold will be at a high level.
For those who decide to change the windows in their house or apartment, and install the slopes with their own hands, I will give advice: you need to wait at least 24 hours after installing the windows and only then finish the slopes with sandwich panels. The advantage of installing a sandwich over plastering is that self-assembly does not require painting skills and is a clean method.
It is important not only to correctly install the slopes, but also how to cut the panels. It is better to cut plastic elements with a circular saw on plastic or aluminum. At the same time, the fine pitch of the teeth is able to cope with the task perfectly. In addition, it is necessary to cut the material at a temperature of +5 degrees Celsius - if you do not observe the temperature regime, then due to a decrease in toughness, chips may appear on the cut line. If there is a finishing of the slopes with pvc panels, then you can cut it with many tools. But the most optimal is a hacksaw for metal, it is possible for wood. You need to cut it face up and with a slight angular slope. At your own peril and risk, you can cut with a grinder, but overdoing it a little with pressure, the panel may break.
Getting started with the installation
It will be quite easy to make the slopes of sandwich panels if you adhere to the rules and sequence of actions. Even if there is no experience in finishing the slopes with your own hands, then there is no need to be afraid of this work. Before starting installation, you need to prepare tools and materials, you will need:
- Sandwich panel - what material to buy, you choose yourself
- Start profile
- F profile
- Liquid plastic - used as desired
- Roulette and knife
- A screwdriver with self-tapping screws, a screwdriver and a drill - the latter are probably in every home.
I have already said that installation should be done at least one day after the installation of new windows. Using a tape measure, you need to take measurements and cut out panels for the side and top slopes. Unnecessary pieces of polyurethane foam are removed with a knife and the installation of the starting P profile begins using self-tapping screws for fasteners. They need to be screwed in with a gap of 10-15 cm. Do not forget that the upper profile is attached first, and only then the side ones should be tightly joined with the upper one. Next, we proceed to the installation of the slopes with a sandwich panel, it is inserted into the grooves of the profile. In the same way, we start from the upper slope.
- First - from above and below we insert pieces of the starting profile into the vertical strip, and then the side panels enter these grooves.
- The second - the panel is simply attached end-to-end with the window sill and the upper slope, after which the gaps are closed with the help of liquid plastic.
When this stage is completed, it remains to give the slopes a finished look. To do this, use the f profile, it must be fixed at the edges of the sandwich canvas. For additional thermal insulation, the voids between the sandwich sheet and the wall are filled with polyurethane foam - this process does not bring any inconvenience, since it is very easy to dismantle the profile. After filling the voids f, the bar is returned to its place.
The final stage after the installation of metal-plastic windows is the internal and external finishing of the window slopes. For interior work, various materials can be used, but slopes for windows made of sandwich panels have proven themselves best. This is due to the technical characteristics of the material used and the ease of installation. How to make slopes from sandwich panels will be described below.
What are slopes
This is a structural element of a window opening niche in the form of side inner walls. Window decoration is mandatory, since the functioning of the window structure depends on it. Filling the assembly seam with foam requires its protection from the external environment.
The slope protects the polyurethane foam from destruction
Polyurethane foam is a porous material that insulates the seam, but at the same time is able to absorb moisture and collapse under its influence. If the foam is closed reliably, then you don't have to worry that over time the windows will fog up or freeze through in winter.
Due to the aesthetic appearance of the material, the finishing of the slopes with sandwich panels has a neat appearance.
Composition of sandwich panels
PVC sandwich panels for slopes are of two types: two and three-layer. Two-layer products consist of a decorative outer plastic layer and expanded polystyrene on the back. The three-layer product has a decorative layer on both sides, which provides a more rigid structure that retains its shape well.
The decorative plastic layer can be made in any color scheme, and can also imitate various textures, therefore, finishing windows with sandwich panels of this type is possible in any interiors.
Three-layer structure provides a more rigid structure Thanks to the use of extruded polystyrene foam as the main material of the product, the maximum energy-saving effect is achieved. And thanks to the zero thermal conductivity of the products, you don't have to worry about fogging up the windows and frames.
For finishing slopes, it is recommended to use two-layer panels. Positive traits
The sandwich is used in the manufacture of blind elements for balcony and street doors, as well as balcony enclosing structures. The doors, with sandwich panels at the bottom, prevent heat from escaping. This is due to the fact that the panels for the slopes of windows and doors have the following positive qualities:
Material features
It is important to purchase high-quality material, since otherwise, under the influence of direct sunlight, the panels may lose their shape and turn yellow.
When working with this material, care should be taken with mechanical stress, such as cutting. The material is quite fragile and the sheet can be damaged if the forces are not calculated.
Sandwich panels should be handled with care to avoid material damage. If there is not enough space between the window hinge and the wall, it will not work to install this material. It is important to take into account that the window opening when using this material will decrease on both sides by the thickness of the panels.
Transportation of products can be difficult as the sheets are large. However, in some stores, they are cut into smaller pieces.
Advantages over other finishes
If you are thinking of finishing the slopes of plastic windows with your own hands, then insulated panels are the best option.
When using drywall, you will have to purchase more material than is required for one window. Working with this material is considered time consuming and requires certain skills.
Decorating slopes with sandwich panels is the least labor-intensive in comparison with other methods Plastering will take a lot of time and effort. If you have no experience with plaster, it will be very difficult to create a flat surface. It will take time for the plaster layer to dry. The process of work itself is associated with significant pollution of the surrounding space.
The use of other materials, such as MDF, will look strange. A trim element made of the same material will look more harmonious with a plastic window frame.
Preparation for work
To install the slopes from the sandwich panels with your own hands, you will need the following tools and fixtures:
- Several spatulas of various sizes and a miter box, so that the slab can be cut at the required angle;
- Jigsaw or hacksaw for working with metal;
- Screwdrivers or screwdriver;
- Measuring instruments in the form of a level and tape measure;
- "Liquid nails" and a gun for them;
- Furniture stapler.
Before installing warm slopes, you need to prepare a number of tools Before installing a sandwich panel for slopes, it is necessary to prepare:
Installation of slopes from sandwich panels will be done with high quality with correct measurement of the opening.
Installation
The device of slopes from sandwich panels with your own hands on plastic windows is carried out in three ways: using foam, liquid nails or slats.
Installation of a slope using construction foam is the easiest Whoever made the installation on foam knows that this method is the simplest. The slope for a window made of sandwich panels is assembled in several stages:
It is important to know that the finishing of the slopes should not be postponed indefinitely, but should be carried out immediately after the polyurethane foam dries.
As a rule, repairs in an apartment begin with replacing old ones and then arranging slopes for new plastic windows. There are several options. In this article, we will consider how to make do-it-yourself slopes from sandwich panels. The photos in the article clearly reflect the course of action.
Preparation for work
To install plastic slopes from sandwich panels, you will need:
- sandwich panel;
- "P" profile (starting);
- "F" profile (slope cover);
- liquid plastic (optional);
- roulette;
- sharp knife;
- self-tapping screws 2.5x7mm;
- screwdriver, drill or screwdriver.
Using a tape measure, you need to measure the length and width of the slopes. Taking into account these data, three stripes are cut out of the sandwich panel: the upper one (parallel to the window sill) and two lateral ones.
One caveat: if you plan to finish just one slope in a panel house, then in order to reduce costs, strips of the required size can be purchased from the seller. This saves you the trouble of buying a whole sandwich panel sheet.
With a sharp knife, the excess layer of polyurethane foam is carefully cut off along the perimeter of the plastic window block. It should be borne in mind that work is carried out after the foam has completely dried. It must take at least a day from the moment of replacement of the window, before installing the window slopes from the sandwich panels.
Fasteners "P" profile
According to the size of the slopes, a starting profile is cut, in section resembling the letter P. It is fastened with self-tapping screws exactly along the edge of the window profile. The distance between the screws is about 10-15 cm. In this case, first of all, the profile should be installed at the top. Then the side elements are brought close to the upper profile, leaving no gaps.
Nuance: it is possible to install slopes using a sandwich panel without using a starting profile. In this case, the strips of sandwich panels are inserted close to the window profile 1 cm deep. This is done with step-by-step foaming of the niche to fix the slope. The process is more laborious than using the "P" profile, but the result is more aesthetic.
Installation of sandwich panel strips
The top panel is inserted into the starting profile already fixed with self-tapping screws.
After that, 4 more parts of the starting profile are cut off. Its length is determined by the width of the slopes. The segments are inserted into the side starting profile at the top and bottom on both sides. Then they are fixed with self-tapping screws to the upper part of the sandwich panel and to the window sill.
Nuance: most of the masters specializing in these types of finishing work exclude this stage. In this case, the sandwich panel strips simply adhere to the top strip and to the window sill. The gap at the joints is closed with a special tool - liquid plastic. It, in turn, hardening, acquires the same characteristics as ordinary plastic. There are also negligent workers who use ordinary sealant, and after a short time the slopes lose their appearance: joints treated with sealant darken and become dirty. Either method cuts down on work time and material consumption, and has its supporters and opponents. Therefore, the choice of option is a matter of taste.
Further, a sandwich panel strip is installed from the starting profile, fixed on three sides (along the window opening, at the top on the sandwich panel and at the bottom on the window sill), a kind of structure, from the starting profile. The process of working with the panel from the other side is completed in the same way. As a result, the plastic slope is almost complete. It remains only to give the appearance of the outer cuts.
The last stage of installation of slopes from sandwich panels
To give a finished look to the plastic slope, use the "F" profile, or as it is also called, the slope cover. The profile is cut into strips of the required length, based on the following calculations:
slope length + profile width for side parts and slope length + 2 profile widths for upper slope.
It is advisable to leave the length longer than required. Since in the end the surplus will still be cut off, but the lack of even one centimeter will require a complete rework.
With the help of a ruler and a pencil, a cut line is marked along which the excess edging is cut off. The result is neat right angles.
If desired, the joints are processed with liquid plastic. But you can do without it. The plastic slope from the sandwich panels is ready!
Nuance: for many slope installers, this is the final stage. However, it is preferable to fill the niches between the sandwich panels and the wall with polyurethane foam. For this, the "F" profile, prepared for installation, is temporarily dismantled. The voids are filled with foam, the next day the excess is carefully cut off, and the slope covers ("F" profile) are returned to their places. Thus, additional heat and sound insulation is created in the apartment.

How to make slopes from sandwich panels with your own hands
Decorating slopes is a procedure that is the final touch in the process of installing plastic windows. It not only gives the entire structure an aesthetic appearance, but also with the right choice of material provides protection against mold formation and freezing in the cold winter season.
Those who want the windows in their house to have the above qualities should give preference to finishing with sandwich panels - a material that will help to achieve an effective result when installing slopes.
What is a sandwich panel?
This material is a lightweight slab, multi-layer, where the two outer layers are rigid canvases that can be made from various materials. Insulation (polyurethane foam, expanded polystyrene, mineral wool) is located between the canvases.
Bonding of all elements of sandwich panels performed in two ways- cold or hot pressing. The material itself is of two types - wall and roofing. Most often, sandwich panels are used in the construction of prefabricated buildings.
Standard sizes of sandwich panels in terms of length, width, thickness are:
- 300x115x3.2 cm;
- 300x115x2.4 cm;
- 300x115x1 cm.
Largest sizes have roofing slabs, the parameters of which are 12x1.2x0.3 m.For the construction of internal partitions, slabs with a length of 1.5 m and a width of 1 m are most often used.
For the installation of slopes, use special sandwich panels, 10x1500x3000 mm in size, consisting of the following materials:
- PVC - the outer side of the panel is made from it;
- the back side is made of polystyrene sheet;
- foamed polystyrene foam or mineral wool is used as an internal insulation layer.

Advantages and disadvantages
Positive material specifications:
Disadvantages for sandwich panels it is mainly associated with the quality of the material itself:
- Poor quality panels can deform and become deformed as a result of high temperatures, usually caused by direct sunlight. acquire a yellow tint.
- In addition, poor quality also affects the strength of the products, which in case of unscrupulous manufacture leaves much to be desired.
When buying, it will not be superfluous pay attention to the manufacturer and make sure that the seller has certification of the goods.
How to make slopes on the windows with your own hands?
After installing windows you should wait at least 24 hours... During this time, the polyurethane foam will completely dry, after which it can be cut with a knife flush from the surface of the frame.
Before installing the slopes, you need prepare the working area, remove dirt and treat with an antiseptic.
