How to make warm slopes for windows with your own hands - Review How to make warm slopes for windows with your own hands ... Owners of houses or apartments who have installed new windows often have a desire to put everything in order, namely the surface around. Often this is required not only to create an aesthetic appearance of the walls, but also because when installing a new window system, old slopes are badly damaged, and they cannot be restored, or they come close to the canopy of the window sash, and this makes opening difficult.

Moreover, if you make warm slopes, it will be possible to strengthen the sound and thermal insulation of the window opening, cover the mounting foam, which can be used to fill the gaps between the window block and the wall during installation. Very often, for this, a layer of insulation is laid between the wall and the finishing material.

Slopes for windows with your own hands can be made functional and neat using several popular methods, as well as using different insulation, finishing materials (or those that combine both qualities). To figure out which of the options is best suited for your conditions, you should consider them in more detail.

What materials are usually used for mounting slopes

There are three most popular ways to give the slopes an aesthetic look, each of them is good in its own way, and you can use them in combination with insulation material.

So, on the slopes of the windows, you can install PVC panels, attach a lathing to the or glue a drywall sheet, or level the surface with plaster and putty mixture.

Slopes from PVC panels

How to make warm slopes for windows with your own hands - Review For finishing using a similar technology, you will need to use plastic lining and other fittings that will be auxiliary. They will help to hide the edges of the panels at the junction of the vertical and horizontal surfaces, as well as on the lines of their abutment to the window frame and outer corners of the slopes. In addition to the standard PVC lining, special sandwich panels should be used for cladding, which are made of layers of plastic, as well as expanded polystyrene. Such material will help make installation easier, since you do not need to adjust and install the insulated material.

In addition, in this case, it will be possible not to use some of the accessories.

Like the standard type of lining, sandwich panels are perfect for making out slopes around plastic windows, in addition, if you wish, you can choose the required shade of PVC, which will perfectly harmonize with the shade of the window frame and the interior of the room ... Plastic slopes can be installed with your own hands, without the help of masters - you just need to study the instructions for performing installation work, and then strictly adhere to it during the work.

Plastering of slopes

How to make warm slopes for windows with your own hands - Review This finishing method considered traditional, as it is many years old and is still often used. A well-finished surface can last for a long time, and at the same time it will not lose its beautiful appearance. However, it would be unfair not to note that without the use of an interlayer in the form of a material for insulation, plaster cannot provide an effective barrier to the cold that will come from the window opening. The disadvantages of the method include its laboriousness and the duration of the arrangement, because the solution will need to be applied in several layers, and each must dry well before applying the next one. Moreover, plastering work requires some experience in their implementation, and if there is none, you can simply ruin the surface, and waste time and money.

The process of finishing slopes with mixtures for plastering is rather "dirty", and it will still take a lot of time (sometimes up to 14 days), and in the room where such work will be performed, it will be necessary to carry out wet cleaning every day or not at all to use him.

Plasterboard slopes

Often, apartment owners prefer to use an equally reliable option in order to make warm slopes for windows - decoration with plasterboard sheets. Such material is easy to install, it can be used in tandem with insulation material, the sheathing is durable and helps to level the surface quickly and without nerves. In essence, it is like dry plaster, but installation is much faster than in the "dirty" version. This method does not heavily pollute the room during work and does not require a lot of experience to perform.

It will be enough just to follow the detailed instructions in order to correctly and accurately carry out the finishing work.

At the moment, there are several varieties of drywall, and one of their gypsum plasterboard has a green color, as it can withstand high levels of humidity, and it should be used to decorate slopes. Difficulties in the installation process can be caused not by the material itself, but by its further finishing for applying a decorative type coating - a primer mixture and putty. Without such work, the design of the slopes will quickly become unsuitable, since it has a rather fragile structural structure and it can be used for a long time only for closing the cuts and finishing the surface.

Materials and accessories for the installation of slopes

In order to put in order the window slopes, depending on the option that you have chosen, you will need different materials.

The list of tools will not vary so much - they will be required not only for installation work, but also in order to perform further surface preparation.

Tools to get the job done

For erection work from the selected materials, you need some construction tools.

If you have to do plastering work, then prepare the following:

  • How to make warm slopes for windows with your own hands - Review Spatulas for applying and leveling mortars.
  • Plastering trowel or trowel - these can also be used to apply putty or plaster to wall surfaces.
  • The Corner Aligner is a great tool to accurately and quickly correct the outer and inner corners, which constantly confuses craftsmen during processing.

  • Grater - required to level and smooth plastered / putty surfaces.
  • Falcon - it will be convenient to use when you will bring the solution to the surfaces to be trimmed during work.
  • Plastering trowel is a professional tool, and is required in order to apply and level the mixture.
  • Electric drill and mixer attachment - needed to mix the solution.
  • The container in which the solution will be mixed.

  • Wooden lath or metal profile - required to make guides.

If you need to install PVC panels, you must have at hand:

  • Construction sharp knife.
  • Ruler, angle, tape measure for measuring and adjusting workpieces in the form of panels.
  • A construction gun that can be used with sealant or a construction gun that is suitable for polyurethane foam.

Some tools will be required for all types of installations from the materials listed above:

  • Wide brush to apply the primer mixture.

  • Construction level, since it is with the help of it that you can control the removal of the surface to the ideal plane vertically and horizontally.

Separately, it is required to talk about the tools that will be needed to prepare the surface of the slopes.

  1. Hatchet (a special nozzle-chisel for a perforator) - such tools are needed if the slopes were made inaccurately or located so that they do not make it possible to open the window sashes completely, and therefore you just need to fight them off.
  2. Building Hair Dryer - will be required if you can restrict yourself to removing the old paint coating.
  3. Spatula - is needed if you just need to remove the old layer of plaster, wallpaper, paint from the surface of the slopes.

Now let's look at how to make warm slopes using different materials.

Finishing materials

For the installation of plastic slopes, you will need to buy the following materials:

  • Molding (plastic panels), the number of which will be calculated according to the slope parameters. The panels will be required in order to install them on the sides and the ceiling of the pit, and it turns out that in order to find out the exact amount of required materials, you need to measure the width and height of the slopes, as well as the thickness of the walls.As a rule, an additional 15% must be added to the calculated quantity for the reserve.
  • How to make warm slopes for windows with your own hands - Review The starting rail is made of plastic, which has a U-shape.

  • A rail that has an F-shape (profile).
  • Profiles for internal corners, which are installed at the joints of panels.
  • Material for thermal insulation - expanded polystyrene and mineral wool of the required size and thickness. If you use ready-made sandwich panels with insulation, then you do not need to use additional thermal insulation.
  • Plywood or wood strip with a thickness of 10 to 12 cm.

  • Self-tapping screws.
  • White silicone so that gaps can be bridged between panels.
  • Polyurethane foam - we recommend using professional foam, which is sold in tubes, and not cheap, which is in aerosol cans.
  • Staple staples.
  • Priming compound.

To install PVC sandwich panels, you will need similar materials, except for the corner rail and U-shaped rail. The F-type strip can be useful for decorating outside corners, but you can not use it and replace it with a putty mixture. Which of the finishing options to choose for the corner will depend solely on your preferences.

In order to make warm slopes for windows with your own hands with plaster, you will need the following:

  • Plaster and putty mixture.
  • Finishing putty.

  • Antifungal primer mixture.
  • Painting perforated profile (needed to reinforce the outer corners).
  • Decorative finishing material - water-based paint, ceramic tiles or wallpaper - it all depends on your preference.

When the materials are ready, it is worth learning how to prepare the surface of the slopes for further finishing.

Surface preparation

After everything you need is purchased and prepared, you can start preparing the surface for installing finishing materials.

This process can be done in several ways.

  • If the window is installed in such a way that there is a lot of space around it on the slopes for the installation of finishing with a layer of insulation, then it is often enough just to remove the old layer of paint, whitewash or wallpaper from the surface.

It is easy to remove whitewash or wallpaper from the surface of the walls around the window if everything is soaked in advance, and for this you need to soak with water. Organic or oil based paint is usually removed with a spatula and the surface must be heated with a hot air gun. The cleaned slope should be primed with an antiseptic primer mixture so that there are no mildew spots under the finish, which can not only spoil the wall and finish, but also create an unpleasant odor in the room and an overall unhealthy atmosphere.

The problem is that fungus is often dangerous to human health, so this step should not be neglected.

Most often, the primer is applied in several layers, and each time after the previous layer has dried.You should work not only on surfaces, but even on corners that seem difficult to reach - for this use a narrower brush.

  • The second, slightly more complicated preparation option is the complete dismantling of the plaster layer applied to the slopes.

It is used only if there is a small distance between the slope and the window frame, which does not allow the window to be completely closed.

The second situation, when this method cannot be dispensed with, is the impossibility of installing slope insulation or even using standard PVC panels. To quickly remove a layer of plaster, use a hammer drill with a special attachment called a "chisel-shovel". It perfectly helps to pry off all the layers that are applied to the surface of the wall, and they are removed in large pieces. After that, particles of plaster and dust should be swept off the cleaned slopes - this process is carried out with a wide brush or soft brush. Next, prime the wall with the same anti-fungal primer mixture.


To easily perform the installation and make warm slopes on the windows with your own hands, you need to consider all the options step by step. You can proceed to finishing work after the primer, which is applied to the wall, is completely absorbed and dried.

Plastering without insulation

The process of plastering the surface of the walls around the windows is simple. For clarity, we have found a video instruction for you.

Finishing with plaster with insulation

With this finishing option, many stages are very similar to each other, but there are some features, so it is worth considering it separately .

.. To make it clearer, watch the second video tutorial.

Installation of PVC slopes

PVC panels can be divided into two types - ordinary and sandwich panels, which have insulation in their multi-layer structure. Their installation is most often similar and is carried out using fittings, but sandwich panels can sometimes be joined with a sealant, and they can be glued to the wall on mounting foam or liquid nails.

Sandwich panels can be installed on the surface of slopes and in other ways, without using profiles for accessories, but using polyurethane foam, liquid nails and sealant. The gaps between the planes in this version will need to be sealed with white silicone. The installation work of sandwich panels on the walls of the slopes is much easier, but a relatively flat surface will be an extremely important condition, therefore, before installing the finishing material, it should be leveled and dried.

Further work is carried out in this way:

  • Remove the dimensions from the slopes and cut the panels along them.
  • How to make warm slopes for windows with your own hands - Review Next, apply one of the adhesives to them, and press the panel to the surface.

Please note that if foam is used for installation, then first you need to glue the panel to the ceiling of the window opening.Next, spray the ceiling surface with water in the spray bottle to increase the adhesion of the surface. Next, the foam should be applied around the perimeter of the part to be glued in a thin strip, since the foam often expands, and if there is a lot of it, it can squeeze the material for decoration from the walls.

  • Press the material to the surface, hold it for 7 minutes, and then install the props and leave until the foam dries completely and expands. The support can be made of curved boards, which are pressed against the panel, which should be supported by bars, and install them on the windowsill.

  • Then install the side panels in the same way.
  • Further, if there are unfilled gaps between the trim and the sloping wall, they should be additionally foamed. When it dries and expands, its protruding excess should be cut off with a sharp clerical knife.
  • Next, close the joints between the finishing material and the wall with a special profile, platbands. It is made in the form of a corner and can be of different widths, which makes it possible to close an unsightly joint, even of a large width.

    It is glued to liquid nails and tacked while drying with masking tape.

  • If for some reason there are small gaps between the panels, then carefully fill them with white silicone, which will be almost invisible after drying.

Note that there are other ways to carry out work on finishing slopes, which are slightly different from those described above, but their principle of operation is unchanged. So, you will need to choose a finishing method in advance, whether the main material will be insulated or whether you will be insulating during installation. Next, select a material for warming and fixing parts.

In the end, you will need to decide which finishing method is preferable - with or without a hardware profile.

When you have decided on all the criteria, you can take measurements and buy everything you need for work. making slopes with your own hands for windows is not so difficult if you approach this with care, make accurate measurements and choose the right components.
