Window slopes in a wooden house. Installation: preparation and stages

What tasks do slopes perform?

Slope - the inner or outer part of a window opening. Performs decorative, masking and protective functions. It is an element of window insulation and waterproofing.

Different types of wood are used to install slopes. Coniferous species are most often used. Wooden slopes are used in country houses and cottages. They are quite massive and heavy, so they are only suitable for a private home. The slopes cover micro-cracks and joints, performing the function of insulation. The main tasks of wooden slopes include:

• protect from freezing;
• perform the function of thermal insulation, reduce the degree of heat transfer;
• prevent the appearance of condensation on windows;
• protect against drafts and penetration of cold air through gaps;
• protect polyurethane foam from external influences and destruction;
• maintain a comfortable indoor microclimate;
• prevent the development of fungus;
• perform the function of decorative design of a window opening.

Using wooden slopes you can solve several problems at the same time:

• additionally insulate the window opening;
• provide waterproofing;
• arrange decoratively.

The slopes smoothly transition into the window sill. These structural elements are interconnected. They perform the task of a protective frame. Prevent cold air or rain from entering the room.

Cork slopes

The most rare of all types of slopes are cork slopes

. As the name suggests, they are made from the best natural sound and heat insulator - cork oak bark. The advantages of cork slopes include, first of all, environmental friendliness and a variety of colors. The main disadvantages of manufacturing this kind of slopes include their high cost, susceptibility to mechanical stress and the softness of this material. The technology for making slopes from cork is similar to making slopes from plasterboard.

As you can see, there are quite a lot of options for making slopes. They all have their pros and cons. Therefore, you have to make a rather difficult choice. However, you should not put off resolving this issue indefinitely, as this may lead to damage to the materials used to install the windows. Let your new wooden windows take on a finished look, and the sooner you do this, the better.

Required tools and materials

Installation of wooden slopes is possible with your own hands. In principle, you can use the same materials and tools that were left over from installing a wooden window. You can also buy everything you need at any hardware store. Everything should be prepared in advance. During the work you will need:

• plywood or sandwich panels;
• jointer;
• hand jigsaw;
• corners;
• polyurethane foam or mineral wool;
• level;
• sandpaper;
• a circular saw;
• drill;
• primer;
• screwdriver;
• self-tapping screws;
• thicknesser;
• silicone sealant.

Installation of wooden slopes is carried out at the finishing stage. It is first necessary to prime and putty the inside of the window opening in order to secure the panels to it. For finishing work you will need:

• putty knife,
• putty,
• falcon,
• metallic profile,
• trowel, etc.

You will also need material for finishing and painting wood. Varnish is often used to preserve the appearance of the wood. Tools and materials depend on the installation method and technology used.

Types of slopes for windows

The materials used for slopes are: wood, plastic, plaster, plasterboard. For a wooden window, wooden slopes are also most suitable. Therefore, it is probably logical to start with them.

Wooden slopes

In the manufacture of wooden slopes, glued panels are used. To protect them from moisture and environmental influences, they are treated with a special compound. It is advisable to choose a wooden slope from the same wood from which the window is made; for a window made of pine and buy slopes from pine.

For what? It’s just that in this case, both the pattern and color of the slope and the window block will match. Pine, oak, and larch differ markedly from each other in texture and color, so even if the same varnish is used for different species, the color will be different.

Wooden slopes, like all others, are installed the day after the window is installed. It is not advisable to do this before because in order for the polyurethane foam used to install windows to gain strength, it must take 10 to 12 hours. It’s also not worth delaying the installation of slopes, since moisture and temperature changes can destroy the foam.

The advantage of wooden slopes is that it is a natural material and environmentally friendly, has a fairly long service life, a large selection of colors, beautiful appearance, and is resistant to damage and deformation. The main disadvantage is the high price of wooden slopes, but it is in this frame that your windows will become real diamonds in the house.

Cork slopes

Another type of slopes is ideal for wooden windows. It is made from plasterboard, which is covered with cork oak bark, after which the bark is coated with varnish, oil or wax. Now cork slopes are not used often, but they already have good reviews and recommendations.

They are installed in three stages - installing sheets of the required size, foaming the gap between the wall and the slope, then the joints are treated with silicone sealant. Advantages of cork slopes: environmental friendliness; can be painted in any color; the highest noise and thermal insulation rates among its slope brothers. The quick installation of cork slopes is also a big plus.

Ready-made panels are used; you just need to cut them to size. Disadvantages - the cost is very high and the material is soft. Cork is highly susceptible to mechanical damage.

Plaster slopes

The most common and traditional type of slopes. Suitable for both plastic and wooden windows. Finishing window slopes with plaster is a rather labor-intensive task.

Plaster slopes are made in this way: first the surface is primed, then several layers of mortar are applied using mesh and insulation. The joints between the window and the window block are sealed with silicone sealant, sanded and painted.

The process is not easy, and if you decide to make plaster slopes, it is better to contact professionals. The advantage of such slopes is their low price and the possibility of updating them. Among the disadvantages it is worth noting: low thermal insulation, during installation the window can be damaged or stained, lengthy installation.

Another important point is that if plaster slopes are made in a new building, then during the shrinkage of the house they may crack. Low thermal insulation of plaster slopes can lead to condensation on the windows.

Drywall slopes

Their properties are the same as the previous ones. Inexpensive, easy to renew, just like plaster, plasterboard slopes have poor thermal insulation and the possibility of damaging the window during installation. Installation is similar to cork slopes.

What type of wood to choose for window slopes?

For the installation of wooden slopes, the same material is used as for the window frame. That is, if the entire window structure is made of oak, then oak should be used for the slopes. This is necessary so that the color and shade of the opening matches everywhere. For slopes, hardwood trees are usually used, more often coniferous. They have increased strength. They are resistant to environmental influences. They have a long service life.

A good solution for slopes is to use:

• pine trees,
• larches,
• oak,
• linden trees, etc.

If the frame and slopes are made of oak, then the same wood should be used for the window sill. In fact, you can make slopes from any type of wood. But then you will have to treat it well with a protective varnish to protect it from the sun and rain.

You can use natural wood to design slopes or sandwich panels. FSF is often used - plywood with increased moisture-resistant properties. The top layer is covered with natural wood veneer. The surface is varnished to highlight the type and pattern of the wood. Sandwich panels are used:

• one-sided - from 1200 rubles;
• double-sided – from 1450 rub.

Wooden slopes from manufacturers are practical designs. They have grooves that make installation easier. The convenient connection of the slope elements allows you to install the structure yourself without any problems.

Choosing wood for window slopes

Choosing a material for making window frames is a responsible matter. Many experts recommend making wooden window slopes from the same type of wood from which the main frames are made. And it’s not just a matter of possible aesthetic inconsistency, especially since the combination of several types of wood in one product may well become an interesting design solution. The point is that a window is a rather complex structure, which is located in a border zone with a significant difference in temperature and humidity. And to minimize loads, it is desirable that the materials used in the structure have the same expansion and compression coefficients depending on changing weather conditions. In this case, when changing heat to cold, drought to a period of precipitation, the risk of cracks and warping is lower.

The ideal material for making slopes, and indeed the entire window as a whole, is larch. This is a type of wood with unique properties, which is almost as hard as oak, and only gains strength over time; moreover, it has a magnificent golden-red hue, which over the years acquires a noble grayish tint. In addition, being a conifer, larch is rich in resin containing gum, which prevents infestation by bugs and microorganisms. This hard, durable tree practically does not rot (it’s not for nothing that Venice stands on larch stilts). Interestingly, larch is one of the few wood species that is highly stable and can be used even in its raw form. At the same time, a material with such unique properties costs much less than oak with similar characteristics.

A window with wooden slopes and an oak window sill is an excellent, but very expensive solution. However, it is worth noting that the service life of such products is more than half a century. With this in mind, installing oak windows can be seen as a long-term investment that will pay off over time. When choosing this material for framing windows, you should remember that oak wood is very dense and heavy, therefore, it is necessary to select the same durable fittings for it.

If you decide to use different types of wood to frame a window, then for external slopes for windows in a wooden house we recommend choosing hard, elastic, waterproof and durable varieties. In this case, larch is the best choice. And for interior design, you can choose a different wood that meets the design intent, although the best option is to make all the elements of the window structure from the same type of wood.

Wooden slopes for plastic windows can be designed in the same style. In this case, plastic often imitates one or another type of wood.

Advantages of wooden slopes for windows

Wood is a practical, attractive and environmentally friendly material. It is often used for decorative purposes. Wooden slopes are hygienic, safe, reliable and practical structures. They can make a window opening much more attractive. They do not require special care. Wooden slopes have a long service life. The advantages of wooden slopes are as follows:

• wood is an environmentally friendly material;
• natural wood is not susceptible to fungal development;
• the material has an aesthetically attractive appearance and can complement any design;
• wood “breathes”, promoting air circulation in the room;
• wood does not accumulate moisture;
• wooden slopes prevent the formation of condensation.

The advantages of wooden slopes make them practical. The tree is not exposed to temperatures. Has increased hardness. Can be coated with a protective varnish to prolong operation.

Environmental friendliness of wooden slopes

Undoubtedly, wood is an environmentally friendly material. Wooden slopes are made from natural wood. No formaldehyde is used. The material does not have a negative impact on the indoor microclimate. The window is the only source of air. The use of environmentally friendly materials is mandatory.

The environmental friendliness of wooden slopes allows you to install them in any room, even a child’s room. A wooden structure is much safer than a plastic one. Wood paints dry quickly. There is odorless varnish, for example:

• Tikkurila – from 680 rub.;
• Kompozit – from 470 rub.;
• Alpina – from 530 rub.

Hygiene of wooden slopes

Wooden slopes are hygienic. The material is not susceptible to fungal development or rotting. To achieve hygiene of wooden slopes, antiseptics are used. They prevent the development of bacteria, mold and mildew. The tree does not require special care. It is enough to regularly wipe the slopes from dust. The coating of wooden slopes makes them resistant to moisture, ultraviolet radiation and pollution. To maintain hygiene, the wood should be coated with Senezh, NPO NORTH, and Olvia antiseptics.

Practicality of wooden slopes

Wooden slopes can withstand almost any impact. They withstand the sun, rain, snow, frost, loads, etc. This material can last up to 25 years. The tree has:

• high heat and sound insulation,
• maintains a comfortable indoor microclimate,
• provides an optimal level of humidity,
• prevents the formation of condensation;
• prevents drafts.

The practicality of wooden slopes makes them the best solution for installation in residential buildings.

Availability of wooden slopes

The availability of wooden slopes should be understood as the ability to buy ready-made structures everywhere. You can make your own wooden slopes with your own hands. Wood is an affordable material and affordable. Unlike plastic or plasterboard, you can use wood, MDF, or sandwich panels for slopes.

Any installation technology will do. You can use available tools and materials. Wooden slopes will be cheap. They look attractive and cozy.

Preparatory work

Before making wooden slopes on windows with your own hands, you need to make sure that the window is installed correctly and firmly. If during the inspection it is determined that the block profile of the window has deviations vertically or horizontally, has even the slightest curvature and other defects, all this must be corrected or minimized so that subsequent cladding does not focus attention on the shortcomings. For such purposes, you can use plumb lines, installing them one by one above vertical surfaces.

Preparing the base for the window sill

Next, you need to check with a tape measure whether the sides match. If everything is normal, you can move on to another job. Check for scratches and chips on the profile; the surface should be as even and smooth as possible. Please note that you can install wooden slopes on windows yourself only after dismantling the old parts. The work is performed in the following sequence:

• Old slopes are removed.
• Excess foam is trimmed off.
• The protective coating is removed from the frame.
• Make holes.

Manufacturing of wooden slopes

Wooden slopes for windows can be purchased ready-made. It's cheaper to make them yourself. To do this, you need to prepare wooden boards and process the material. To make wooden slopes you need to perform step-by-step processing of the material:

• it is necessary to level the surface of the board. To do this, it is better to use a jointing machine, which allows you to rid the surface of unevenness and roughness and turn it into an ideal base for wooden slopes;
• then you should remove the excess part of the board and make it the desired thickness. For this purpose, it is better to use a machine that will symmetrically align the planes and make all the boards the same thickness;
• you need to wane one rib. To do this, use a circular saw to cut the angle at 90⁰. To do this, press one edge against the guide and make an edge on the jointing wall;
• now you need to cut the board to the required width of the slope;
• Next, you need to make transverse sections so that the slope turns out to be inclined.

One edge should be rounded. You should get a smooth angle of repose. After this, you can proceed to installation. Wooden slopes can be installed both on the inside and outside of the window opening.

Plaster slopes

Plaster slopes are the traditional and most common option for window design; fortunately, the modern construction market has a wide selection of the latest plaster mixtures, and the main costs are associated with paying for the work of specialists who guarantee an attractive appearance and good quality. Plaster slopes are used for interior and exterior decoration in any buildings with completely different windows. Just like plastic windows, wooden ones also go well with plaster.

Making plaster slopes is the most labor-intensive way to finish windows. Installation of plaster slopes is carried out in the following order: first, the walls are treated with a primer, then several layers of plaster are applied with an insulation device and using a mesh, the joint between the wall and the window block is treated with silicone, after which the surface is sanded and then paint is applied to it. Since making slopes from plaster is a very difficult task, it is not recommended to do it yourself - it is better to entrust this task to professionals.

The advantages of plaster slopes include reasonable cost, as well as the possibility of updating them. The downside of this type of finishing is the rather lengthy installation, the high probability of contaminating or damaging the windows during installation, as well as the lack of proper thermal insulation. Due to the low thermal insulation of plaster slopes, condensation may form on the surfaces of windows and glass. In addition, the house, especially if it is recently built, may shrink, which will lead to cracking of the plaster.

Installation of wooden slopes on wooden windows

Wooden windows look harmonious with slopes made of the same material, so wooden slopes are often used to frame wooden windows. This design looks solid. Installation of wooden slopes on wooden windows is carried out in several stages:

• the finished panels must be sanded and the ends made smooth. To do this, use a square;
• Next, you should make holes in the slope. To do this, use a drill and a wood drill and then insert self-tapping screws into these holes;
• then you need to place the slope to its location. If there is a distance between the slope and the box, then you need to block the ledge with wooden blocks. Then you need to insert the screws and screw the panels;
• The screws need to be screwed in with a screwdriver so that they go slightly into the wood. The places where the screw caps are located must be treated with putty;
• vertical slopes are made in the same way as horizontal ones. After installing the wooden slopes around the perimeter of the window, it is necessary to attach the platbands.

Wooden slopes must have the width of the window opening, not protrude or sink into it, therefore, before installation, be sure to take all the necessary measurements.

Installing slopes in a wooden house

To make high-quality external slopes for windows, the material must be very resistant to moisture. For interior decoration, you can omit the requirements and choose any desired material. Window frames can be finished with plastic, wood or clapboard. Slopes made of lining are considered to be the most universal of the listed materials, since the material is perfect for finishing a house both inside and outside .

Moisture-resistant material is used for exterior finishing

To install window slopes you will need:

• wood panels;
• corners;
• set of self-tapping screws;
• polyurethane foam;
• screwdriver

Work area:

1. If the walls in the house are not even, it is necessary to install lathing, the slats for which must be selected in proportion to the thickness of the panel for finishing. When preparing the bars, consider not only the size of the slopes, but also the installation method. The sheathing should be attached with self-tapping screws around the perimeter of the window frame using a screwdriver or drill. Carefully fill the vacated space with material with a thermal insulation function. If the walls in the house are smooth and beautiful, you can safely skip the first step of lathing and go straight to the slopes of the window frame.

   
   For interior finishing work, lining is most often used

2. Next, we fasten the paneling with a screwdriver onto the screws. When installing vertically, we fix the slopes on windows from the outside or inside according to the area of ​​the frame where the grooves should lie. Using fasteners, secure the panel to the body. When installing horizontally, start work from the bottom side, having previously mounted the starting strip on the frame. We fix the window slopes first in the strip openings, then with each other.

   
   When installing the lining horizontally, installation begins from the bottom side

3. We provide installed slopes with corners that will help hide minor errors and defects, and also contribute to high tightness.

Installation of wooden slopes on plastic windows

There are two ways to install wooden slopes on plastic windows. Plastic double-glazed windows and wooden slopes look harmonious, so these materials combine perfectly. To make the structure look attractive and reliable, you can use two installation technologies:

• on polyurethane foam. This method is quite simple and requires preliminary preparation of the slopes and the presence of polyurethane foam. Each panel is attached separately. Be sure to trim the corners so that they match perfectly. Then you need to apply polyurethane foam over the window wound. It will quickly increase in size, so do not overuse it. Then the slopes are assembled and connected to the opening. The foam will provide insulation, and the slope will protect it from the external environment. You can additionally treat the joints with silicone sealant, which will prevent moisture from getting under the slopes.
• on fasteners. This method is a little more complicated, since it requires the preliminary installation of special fasteners that will hold the panels. After the slopes are leveled and have suitable parameters, mineral wool is inserted into the gap between the frame and the opening, which acts as insulation. The cotton wool is covered with a film, for which you can use masking tape. Then a frame of panels is attached, which is connected with self-tapping screws. They need to be twisted very carefully so as not to damage the panel. Then the entire structure is attached to the frame and fixed with fasteners.

If you are not sure that you can install wooden slopes yourself, then contact the professionals. This work has a lot of specific nuances. It depends on them how well the slopes will perform their functions.

Features of slopes: summing up

Slopes for windows made from different types of wood are a modern, aesthetic and functional style solution, the only disadvantage of which can be considered the high cost compared to plastic. But if we take into account the expected service life of wooden products, and this is more than a dozen years, even if we are talking about parts made of pine or spruce, then the price is not so high. But throughout the entire period of operation, the window will look noble and perform its functions properly.

The price of slopes depends on several factors - the size of the windows, their number, the complexity of the configuration, as well as the selected material. But whatever you choose, you will be offered competitive prices and extensive experience in the production and installation of window and door structures. To find out how much it costs to install slopes on windows, contact our experts by phone or fill out an application on the website, and we will soon contact you.

Features of wooden slopes

Wooden slopes are made from well-dried wood sandwich panels. If the wood is wet, it may chip. It is better to install slopes the next day after installing the double-glazed window. By this time, the polyurethane foam should be completely dry.

After installing the slopes, the wood must be varnished. This will emphasize the naturalness of the material. You can also paint the slopes with paint. It is better to use oil or acrylic.

The main features of wooden slopes are their practicality and aesthetics. They look very elegant and attractive. They have many protective properties that other materials do not have. Wooden slopes can completely change the appearance of a window. They do not require special care and additionally insulate the window opening. They are more practical and faster to install.

Features of operation

Wooden surfaces are durable and wear-resistant. These indicators for wood are much higher than for plastered and plasterboard surfaces. In addition to these properties, wood is very decorative in itself. In order to highlight the beauty of this natural material, there are special translucent protective compounds that give the wood a certain tone without overlapping the pattern.

In addition, wooden slopes can be completely painted - natural acrylic paints are best suited for these purposes, which, in addition to their protective qualities, can give the slopes any desired color. In addition, wood is durable and, under favorable environmental conditions, does not require any strict care rules.

To summarize, I would like to note that wooden slopes are an excellent material for framing windows. They are very easy to install compared to their plastered and plasterboard counterparts, because in this case you can get completely finished panels for finishing without resorting to subsequent processing. By the way, processing wood and installing slopes is not at all troublesome and is done quite quickly.

In addition, wood is an excellent material for bringing design ideas to life. It is beautiful and environmentally friendly, gives the space a complete and aesthetic look, and if you approach the installation of slopes responsibly, they will delight their owner for a long time.

Insulation of slopes

Insulation of slopes with penoplex
Finishing slopes with wood in itself significantly insulates the room, but the effect can be increased by using the following materials:

• Styrofoam. One of the most affordable materials, it has good thermal insulation characteristics. When insulating with foam plastic, it is better to install wooden trim on the frame. Options with gluing are also possible, but the fixation in this case will not be as rigid, although quite sufficient as for slopes.
• Penoplex . A more expensive analogue of polystyrene foam, superior in energy-saving characteristics. In addition, penoplex is denser and does not accumulate moisture. The installation methods are in all respects similar to those described above for foam plastic.
• Mineral wool . Used in a frame version (simply placed between the mounting rail). When choosing such insulation, you should use mineral wool varieties that are not prone to absorbing moisture.

Getting to know the finishing

Types of slopes

Explanation. A window or door slope is the smooth (external or internal) finishing of the remaining section of the opening, which is adjacent to the window frame. Such a device is needed not only for decoration, but also to cover all the gaps between the frame and the opening, as required by the instructions. Window sills and door thresholds serve the same purpose.

In the photo: option with putty

• Most often, such finishing is carried out with cement-sand mortar and/or putty - this option is quite labor-intensive, but it results in the lowest price for materials in relation to the quality of the finished product. First, as a rough surface, the opening is plastered with cement-sand mortar (if necessary, additionally bricked), and then, after drying, external or regular putty (depending on the side) is applied to the slope, which is the final finish for painting. In some cases, especially on the street side, special external plasters are used or limited to cement-sand mortar.
