Solid oak window sills in a modern interior

Wooden window sills go well with windows made of laminated timber or laminated profiles, which is why many customers prefer these products. Models made using modern technologies differ from basic analogues that can still be found in old buildings. Today, such window sills are made in different ways from several types of wood, thanks to which you can choose a decor that goes well not only with the window frame, but also with the flooring and other interior items. At the same time, some buyers who want to install wooden models are worried that they will not last long enough and various problems will arise during operation. Find out how justified their fears are from this article.

DIY dyeing process

Before you start painting, you must thoroughly clean it from dirt using detergent.
If there are cracks or dents, they must be sanded with sandpaper. Next, degrease, putty and sand after drying. If necessary, you need to remove the old paint. To do this, you need to treat with coarse-grained sandpaper, at the end of the work they work with fine-grained sandpaper. But it is important to work very carefully so as not to damage the window sill. Next, remove dust from the windowsill. You can purchase a special remover for plastic at construction stores.

The remover contains toxic substances, so when using the product, it is important to ventilate the room

You can purchase a special remover for plastic at construction stores. The remover contains toxic substances, so when using the product, it is important to ventilate the room.

Masking tape is used to cover all joints with windows and slopes to protect against accidental paint. Next, use a degreaser and primer. Coating with primer will allow the paint to be evenly distributed over the surface and maintain its updated appearance for many years. The soil should dry well.

The paint is applied in several layers

It is important to ensure that there are no drips and that the product is applied evenly. You can use the coloring agent using an aerosol

The coating dries in several ways:

• Natural method at room temperature and humidity not more than 70%. As a rule, the window sill is ready within 9 hours.
• Forced method - hot air from a hair dryer. The air temperature should be no more than 80 0C. Drying time up to 2 hours.

The top is treated with a high-gloss varnish, which is water-based. Varnish allows you to create a protective layer and increase the optical effect, enhancing the brightness of the selected paint color. If you add metallized decorative paste to the varnish, the resulting coating will have a metallic, mother-of-pearl or gold effect, and the window sill will be unusual. To restore the aesthetic appearance of a plastic window sill, you can paint it

It is important to keep the steps consistent and allow enough time for each step to dry. Applying paint will avoid wasting money on replacement.

Materials and designs

Wood is one of the building materials that is sensitive to moisture and sudden temperature changes. In this regard, it is often susceptible to deformation and cracking, which are associated with the heating system located below the window sill block. To prevent this from happening, it is necessary to choose an option made from laminated, tongue-and-groove or milled wood with a moisture content of less than 10%.

Let's consider the design features of each type:

• One-piece design. One board was used to make the window sill block. Depending on the environment, the product undergoes shape changes (warping).
• Milled design. This type of structure consists of solid elements with grooves on one side and ridges on the other. The underside of the board has one or a pair of grooves necessary to eliminate the possibility of deformation of the wood.
• Tongue-and-groove design. It is characterized by the presence of a tongue-and-groove connection. The lower surface assumes the presence of recesses for free air circulation.
• Glued lamella. Various-sized wooden blocks glued together under high pressure.

The wood lends itself well to processing. The highest quality, attractive in appearance and expensive product is a window sill block made of oak or beech. Window sills made from pine or larch, due to their natural soft texture, are much cheaper.

First of all, the wood is thoroughly dried. The moisture content of the wood structure should be less than ten percent. After which the polishing and impregnation procedure is carried out using mastic, which consists of oil and wax. This reduces the moisture permeability of wood. The final stage is the application of a decorative coating. The coating used is a special paint intended for wood, stain or wax.

The most budget-friendly options include window sill blocks made from sanded chipboard and MDF. They have different densities and are pressed wood materials that are covered with a decorative polymer film. In addition to the inexpensive price, the material will amaze you with a diverse palette of color shades. The edges of a window sill block made of chipboard are often curved downwards.

Materials for making window sills

Several decades ago, there were no questions even about what material was used to make the window block; everyone understood that we were talking about wood.

Now the choice has expanded significantly:

Solid wood window sills as a work area

1. Plastic is available and inexpensive. The most common color is white, but you can choose an option that imitates marble or wood. Plastic is an artificial material with its inherent disadvantages. Products made of plastic, especially white, quickly lose their original color. There is a risk of release of harmful substances under the influence of heat.
2. Chipboard and MDF are rarely used for making window sills. The slabs are inexpensive, but short-lived; under the influence of moisture, the entire top layer rises.
3. Natural or artificial stone is a durable, expensive, heavy material. This fully applies to concrete. Disadvantages include the complexity of installation and problems with repairs.
4. The most popular material is still wood. Familiar wooden white window sills can be found in old houses. The array has proven its practicality and reliability.

Modern wooden window sills come in a variety of sizes, shapes, and colors. Companies engaged in the manufacture of custom-made wood products will develop a unique design project and produce a window sill that can be used as an additional workplace, recreation area, computer or kitchen table.

Operation of wooden window sills

Rice. 15. worn wooden window sill

Caring for wooden products is divided into 2 main stages:

Constant inspection of the surface and elimination of resulting defects

It is necessary to pay attention to cracks or other defects in a timely manner. They are easy to remove at the very beginning, but if you leave everything to chance, then the service life of even a reliable object made of oak from several centuries will be reduced to a couple of decades. Preventative work

Even if there are no cracks, chips or mold on the product, it is necessary to periodically clean the surface from dirt and dust. And also carry out preventive painting or varnishing.

The main enemy of timber is moisture, so during daily cleaning you should not use abrasive cleaning agents. They leave microcracks and require a lot of water to wash off. It is best to use a damp cloth and then wipe the surface dry.

If there are flowers on the window, it is necessary to periodically check the condition of the window “visor” under the pots. Plants that require constant care and watering often leave rusty circles that are difficult to get rid of.

It is best to install the frame at the end of all repair work to avoid frequent wet cleaning. If dusty work after installing the window sill is unavoidable, it is recommended to wrap it in film and secure it with nails. The stove itself does not attract dust, but in case of repairs it is advisable to protect an important part of the interior of the room.

Re-varnishing or painting a window sill does not have a clear time frame. This is set by the user himself. This could be once a year or once every few years. It is best to apply a new coat of paint to a sanded slab. This way you can avoid cracks in the paint that may form when the new layer dries.

Features of wooden window sills

Natural wood has a lot of positive qualities; each type of wood has unique properties. If it is necessary to preserve the material pattern of the cut, the surface can be varnished. If you want to choose a color to match the interior, you can give it the desired shade using stain or paint. The modern construction market offers products that protect the surface of wood without imparting an unwanted shine.

The popularity of wood products can be explained by the following reasons:

1. Environmental cleanliness, safety. Natural material does not emit harmful substances, such as plastic. There is no need to be afraid of radiation, as is the case with a window sill made of natural stone.
2. Durability. Stone and concrete can last just as long, but they cannot be restored on your own. Repairing a wooden surface is not difficult; just remove the damaged layer, sand it, and varnish it.
3. If you use ordinary wood species, the manufacturing price is affordable for all segments of the population. The cheapest options are pine and larch.
4. Wood provides reliable thermal insulation.

The material is well processed, you can make a window sill of any shape - rectangular, oval, curved.

When choosing a material, it is necessary to take into account the disadvantages.

• Wood actively absorbs moisture; regular treatment with protective agents is necessary.
• Do not allow puddles to form on the windowsill from condensation or after watering flowers.
• A window sill made of valuable wood, made according to an individual design project, is more expensive than a plastic one, offered complete with a window block.

But with proper care of a wooden window sill, that piece of furniture will become its decoration, making the life of family members more comfortable and cozy.

The FogWood company produces window sills - oak, ash, larch, elm and others. The master will come to your home or office, take measurements, bring samples of material, and accept your order. In a few days you will become the owner of an elite product, the shape and size of which you will choose yourself. The products are made of high-quality material, which will retain its beautiful appearance, strength and reliability for many decades.

When is restoration necessary?

Plastic is a relatively practical material. Elements made from it are easy to maintain, easy to install, have a wide range of colors and are low in price. But at the same time, they are susceptible to mechanical damage and sensitive to elevated temperatures (they swell and can crack).

What to do if the following appears on the windowsill:

1. Chips, cracks and scratches.
2. Traces from flower pots and hot objects.
3. Spots faded by sunlight.
4. Damage caused by chemical surface cleaning agents.

The plastic surface of the window sill is subject to mechanical damage. In this case, repairs of plastic window sills are carried out depending on the degree of damage. There are special restorative agents for these purposes. If these are minor damages, the repair is done using putty; for multiple chips and cracks, a laminated film is used, and for serious problems, a special overlay is used.

Preparing the base of the wall

The polyurethane foam must come into direct contact with the wall material. Therefore, the base of the opening is cleared of construction debris and foam that has excessively protruded when foaming the space between the frame and the walls. The foam is also cut out from under the lower window profile to a depth of 2-3 cm to partially pinch the window sill fabric by the window structure.

If the distance between the lower plane of the installed window sill and the base of the wall is less than 1 cm, a recess up to 70 mm wide and 20-30 mm deep is cut into the wall to form a foam seam on which the plastic panel will lie.

Manufacturing technology for wooden window sills

There are two technologies for manufacturing window sill countertops:

• Array;
• Plywood.

To make an array, one solid board is taken. Most often, such products are not very wide and quite expensive, especially if the choice falls on valuable varieties of wood.

Rice. 2. example of making plywood

A glued window sill board is several narrow slats that are glued together under pressure and temperature using a press. The slats are glued together in two layers, but each layer consists of several narrow slats. Due to this, the tabletop loses its appearance due to noticeable joints. Manufacturers can remove this defect by gluing with veneer.

Plywood and solid wood require drying. Poorly dried timber, even with proper use, will quickly reveal defects. The wood begins to deform and crack. The first signs of improper drying after installation will appear within a month.

Drying is followed by polishing, which grinds off excess parts. The tabletop is polished almost smooth

In this case, special attention is paid to the upper side. Plywood also goes through this stage, but if the product will be covered with veneer, such attention to detail during sanding is not required

When making plywood, different types of wood are usually used. The most valuable ones are taken for the top layer, as well as for the “visor”. In the middle, pine slats are usually used as the optimal material.

The treated tabletop is cut to fit the window. In this case, the corner should go into the grooves in the walls, and the “visor” itself should stick out at least 6 cm further than the window slope.

REFERENCE! Measurements for the window sill play an important role. An array that is too thick can cause poor heating of the window glass and condensation. For reliability

Window sill treatment

Rice. 3. varnishing the boards

After the grinding stage, part of the future window structure is treated with various liquids. The antiseptic prevents the appearance of mold and mildew, so the underside is painted with special care, since it comes into contact with the battery and is poorly ventilated. If there is high humidity in the room, the area under the window is an ideal place for mold to grow.

Depending on production regulations, the slab can be covered with mastic, wax, or varnish. These substances are designed to extend the life of the countertop and give it a beautiful appearance. Another reason to use wax and varnish is for added moisture protection. The log reacts rather poorly to high humidity, so impregnation and polishing are needed to “keep” the wood in its original state without increasing in size and deforming the structure.

Paint or tinting compounds are often used to change the color of the countertop. This treatment depends on the wishes of the client, if the special color is in harmony with the interior of the room. However, more and more often, the most natural colors are used, which are intended to indicate unity with nature and the overall environmental friendliness of the set item.

Which window sill to choose?

Window sills are now made from different materials, but will all of them be equally appropriate for a wooden window? It is relevant to install a Euro window sill; is this solution applicable to a wooden window? These questions need to be sorted out now, before you have yet purchased a window design element. We will definitely tell you about the materials, but for now you need to understand the main requirements that the window sill must meet.

• The structure can hang no more than 10 cm above the wall.
• The heating element should not be blocked by more than 2/3. But you can make holes in the window sill and cover them with bars. In this case, you will get a really wide window sill that will not interfere with the circulation of warm air.

​Wooden elements

First of all, wooden window sills are considered; for plastic windows they are also attached, but in the case of wooden windows this option is the most advantageous. Window sills are covered with antiseptic substances and varnish/primer. If you order a window and a window sill at the same time, their shades will not differ. Otherwise, achieving full compliance will be difficult.

Different types of wood are used in production. It is not necessary to choose one wood for the window and window sill; you can combine, for example, oak and larch.

Stone elements

Wood and stone are a luxurious combination that looks noble and rich. Stone is the strongest and most durable material used in the production of window sills. Granite and marble are most often used. Products made from such materials do not scratch, are not exposed to moisture, look great in any interior, and do not require complex care.

Such window sills are cold and can freeze, have a high cost and require careful selection of shade so that it looks harmonious with the wood.

Verzalite elements

This material was specially developed for such structures. Verzalit is a slab that is created under pressure using high temperature from wood chips. This composition is impregnated with resin, which makes the finished element even more durable.

On top of the monolithic slab there is a plastic continuous lamination. This decorative coating provides reliable protection against mechanical damage, chemicals, thermal and solar exposure. Such window sills are safe for people; during operation they do not emit harmful substances.

Plastic elements

How to install a plastic window sill on a wooden window is a question that interests many. We ask you to take your time and consider the following points. Such designs are attractive due to their low cost, immunity to moisture and temperature changes. You can order a plastic window in any color, including a finish similar to the wood from which the window is made.

We will tell you how to attach a plastic window sill to a wooden window, but first think carefully about your choice. No matter how good plastic structures are, you should not combine them with wooden windows. This combination is losing in several respects. But if you really want it or simply have no choice, then you can put a plastic window sill on a wooden window; no one forbids this.

Chipboard

Window sills from such material are being created less and less often. The reason is the harmful effects of moisture on such an element. If you ordered wooden windows, then let their framing be appropriate.

Technologies for manufacturing wooden window sills

Currently, several methods are actively used for the manufacture of these elements of window structures. Both the cost and characteristics of products largely depend on technology. Today, manufacturers offer customers the following types of window sills:

1. From solid wood
   - products made using traditional methods, which, if technology is violated, can turn out to be very capricious during operation. After all, an insufficiently dried and poorly treated solid board with a high degree of probability can become deformed even under normal conditions. This technology is used for products of all price categories, but premium products have the highest quality.
2. Spliced ​​(plywood)
   - products from many individual bars connected to each other. These window sills are less susceptible to deformation. This type of combined board can also be called “joined array” and this can be seen from its heterogeneous structure - the boundaries between the bars are clearly visible on the surface of the window sill. Plywood is perfect for modern interiors with an extraordinary design.
3. Veneered
   - spectacular window sills, the base of which can be either plywood or a board made of spliced ​​solid wood. The advantage of such models is that at minimal cost it is possible to create an imitation of products made from elite wood species. However, during operation, if production technologies are violated, the veneer may begin to peel off or crack. When choosing such a modification, you need to pay special attention to the quality of the products.

Regardless of the type of window sill, ventilation grilles must be cut into wide products. Otherwise, condensation flowing down will accumulate on the windows, which will lead to deformation of the board.

DIY window sill installation

You will need tools:

• tape measure for taking measurements of products and materials
• level to determine the degree of inclination of the window sill
• square for precise cutting of workpieces
• brush for treating wood with antiseptics and anti-rotting agents
• spatula to remove excess fixing mixture
• polyurethane foam for filling voids and cracks
• cement, sand for fixing mixture
• antiseptic agents for wood (if the window sill is installed in a wooden house)
• cutting tool: saw, machine, etc.

Having decided on the type of wood and the product itself, proceed to trimming. Leave about 10-15 cm above the length of the window. The window sill should protrude 7-10 cm in width. It is advisable to sand and polish the workpiece so that it takes on an attractive appearance.

Attention: at a distance of 2-3 cm from the outer edge of the board on the bottom side you need to make a wedge - a groove for draining water. Condensation will flow down it

The window sill can be made not only from solid material. It can be made from several parts. In this case, you will need wood glue, dowels (wooden nails) and dowels. Connect the parts of the product together using glue and dowels. The material must fit tightly together to prevent the possibility of subsequent disintegration into its component parts. Such a structural element is less reliable, but if approached correctly it can be an original decoration for a plastic window.

An important point in installing a wooden window sill with your own hands is to process the material efficiently. Any varnish for wood treatment is suitable, choose the one you like based on color and features. The coverage should be uniform and without streaks.

Window sill installation: stage 1

First you need to clean the installation site. To do this, remove all construction debris, dust and dirt. Using a level, determine the curvature of the surface, and if the result is unsatisfactory, proceed with leveling. Wedges can be used to correct minor unevenness.

If the window sill is installed on a concrete or brick surface, a fastening solution is applied to it. If you are installing a window sill in a wooden house, then it is enough to treat the working surface with antiseptic agents. This will prevent rotting and mold formation.

Window sill installation: stage 2

After preparing the surface, it's time to start installing the wooden window sill itself. Cement mortar is used to secure the structure. The bonding mixture is applied until the leveling wedges are hidden. If they are absent, the amount of cement is adjusted at your discretion.

After applying the solution, a wooden window sill is placed on top. When pressing, some of the cement mixture may come out; remove the excess with a spatula. An important point is to install this element level; it would be ideal to use a laser.

Tip: check the slope of the window sill with a level before the cement hardens. Adjust or remove it if necessary. To make the window sill more secure, you can use self-tapping screws. This method is suitable only for those who are going to install a window sill in a wooden house. From the outside of the frame you need to screw in the screws so that they go into the installed product by 4-6 cm.

Window sill installation: completion

After the solution has dried, cosmetic operations are performed. All remaining cracks and holes must be filled with polyurethane foam and its excess must be trimmed after hardening. Remove drops of solution and stains from the window sill itself. Installing a wooden window sill with your own hands can be considered complete.

How to install plastic window sills and slopes with your own hands

Modern construction trends involve the use of the most ergonomic materials. The requirements of the average buyer are as follows: the material must be light, durable and inexpensive. Previously, wood was used almost everywhere, but now it is considered a premium material. It was replaced by plastic - it is more durable, cheaper and has almost unlimited decorating properties. Most often, plastic is used in metal-plastic windows, which are now installed almost everywhere. In addition to them, it is necessary to install a window sill and slopes. Each element plays an important role in everyday life, and their selection and installation must be approached with particular care.

No. 4. Wooden window sill: pros and cons

A wooden window sill is an integral addition to a wooden window. Previously, only such products were used in residential buildings, but today they are being replaced by cheaper plastic. Nevertheless, there are still many fans of wooden window sills, since they have many advantages:

• highest strength, especially when it comes to oak, beech or larch wood;
• naturalness and environmental friendliness;
• beautiful appearance, pleasant to the touch surface;
• excellent thermal insulation qualities.

There are many disadvantages to a wooden window sill: price, sensitivity to temperature changes, high humidity, low resistance to ultraviolet radiation, fire, microorganisms and insects. It is better not to spill water on it or place hot dishes.

Manufacturers are trying in every possible way to improve the performance of wooden window sills and extend their service life. The wood must be well dried and treated with antiseptics, then covered with paints, varnishes or enamels, which protect the material from moisture, pests and temperature changes, and at the same time help to emphasize the unique structure of the tree. No matter how hard modern industry tries, wood still remains quite demanding to maintain, and every few years such a window sill will have to be coated with special wax or parquet varnish.

The most commonly used window sills are from the following species:

• coniferous species, with larch having excellent strength characteristics, and pine, spruce and cedar are very beautiful, but soft wood, especially susceptible to changes in humidity and temperature, so you should be extremely careful with such products;
• deciduous species, including oak, hornbeam, cherry, beech, ash, are more expensive, but in terms of strength they are much better than most coniferous species;
• mahogany and ebony are exclusive, which cost a lot of money and will complement a luxurious interior in a classic style.

Window sills are rarely made from solid wood - glued panels are more often used. Those who are ready to choose a window sill from an array should prepare for big expenses. Thin layers of wood are glued together under the influence of high pressure and temperature, and the result is a product that is almost as strong as solid wood, but at the same time acquires additional useful qualities, for example, less susceptibility to deformation. The thickness of the wooden window sill in any case should not be less than 28 mm.

What types of wood are window sills made from?

For the production of wooden window sills, pine, cherry, hornbeam, oak, beech and other species are used. For premium products, mahogany or ebony is used. In this case, most often the window sills are made of the same type as the window sashes. Among the products in an affordable price category, window sills made of oak, hornbeam and ash should be highlighted. They are more beautiful and durable than products made from soft pine or larch. Read more about the properties of the most popular types of wood used for the manufacture of window structures on OknaTrade.

The best types of wood for making window sills

Rice. 6. wooden window sills from different types of wood

You can order a window sill from almost any type of wood. The more rare the breed, the higher the cost will be. Also, the rather high price is due to the good properties of a particular breed. For example, hardwood is more resistant to moisture and temperature, and the cost will be higher.

The most popular varieties that are used to create any part of the window are:

• Pine;
• Larch;
• Oak.

You can also find good reviews for ash or spruce. Some experts prefer cherries, but this opinion is controversial among professionals. Some clients prefer exotic species: merbau or ebony. Most of these varieties have special features that make buyers choose one or another variety.

Pine

Rice. 7. pine plywood

Pine is a budget variety and is usually used as a “filler” for plywood. In this case, the outer layer is used more expensive, due to which an unscrupulous seller can easily deceive the buyer and charge a higher price than the product is really worth.

Pine is quite light; when installing it, you do not need to worry about the weight that the supporting concrete pads will have to bear. Lightness also has negative sides, because “airy” pine is easily deformed by external damage. For example, a dent may be left by an accidentally thrown hammer or flowerpots with flowers constantly standing in one place.

The advantages of the raw material include its natural resistance to insects and mold. It contains enough resin that antiseptic treatment becomes only a pro forma, not a mandatory stage of production. But, despite its resistance to parasites, pine is not chosen so often, as there is a strong opinion about its “cheap” appearance. This can be corrected by painting it to resemble oak or other valuable species.

Larch

Rice. 8. larch board

In terms of its “technical” characteristics, larch is close to conifers, but has a higher cost. First of all, this is due to its beautiful appearance. If spruce and pine have a light shade, then larch is darker, due to which it is considered more beautiful.

It is more difficult to work with larch at the harvesting stage. A large amount of resin will subsequently prevent rotting of the interior item, its deformation, and the formation of mold or mildew, but it is difficult to process a resinous surface. Grinding requires significant effort, and artistic carving is practically not used.

Sometimes you can find cheap larch. This is due to product defects at the drying stage, when microcracks form inside. Such defects significantly reduce the service life of the window part.

Oak

Rice. 9. oak window sill

Oak is one of the most presentable types of raw materials, which has a very long service life. With proper care, an oak product will outlive even the buyer’s grandchildren. The advantages include not only a noble appearance, but also good resistance to moisture and heat, which is why it is easier to care for than other types of wood.

Oak is very hard, which means that the buyer should not be afraid of marks from flowerpots and other objects. The corner will become an additional place for relaxation, which will calmly endure all adversity.

However, oak boards are expensive. The high cost is obtained not only due to the good properties of the rock, but also due to the complexity of its processing. Solid oak does not lend itself well to sanding, so it must undergo several labor-intensive sanding processes before it reaches the customer’s apartment.

A tree for all times

Despite the difficulties in operation and high cost, wooden window sills are still popular. Firstly, they look harmonious with wooden frames; secondly, natural wood, with its natural palette and natural warmth, simply has many fans. Wooden window sills are made from solid wood or from lamellas glued together under pressure. The raw material used is wood from both valuable species (oak, beech, ash, cherry, maple, etc.) and cheaper conifers (pine, spruce, Siberian larch). There is also a veneered version, and under the thin “valuable” layer there can be hidden not only a cheaper solid mass, but also a chipboard.

Molding technology allows you to embody original ideas

Installation stages

Regardless of what material the window sill is installed on a plastic window, the installation process is carried out using identical technology. The main feature of this method is its simplicity and the lack of special skills. How to install a plastic window sill correctly or how to install a wooden one? The choice of material is directly influenced by the strength indicator, since this indicator is different for PVC and wood products. You can achieve high strength and reliability of wooden and plastic window sills during the installation process. Correct and competent installation of the window sill with your own hands will prevent its subsequent sagging and deformation.

Structure of a plastic window structure

Installation of different types of window sills on plastic windows

You should understand in more detail how to install window sills on plastic windows, and a step-by-step description of the work will help with this:

• The first and mandatory step is to thoroughly clean the working surface on which the workpiece will be mounted from construction debris and dust.
  The surface on which the window sill will be installed must be clear of debris
• To perform further actions, you will need a building level to help determine how level the surface is. If there are irregularities, the workpiece is aligned using wedges and beacons. In order to install a wooden or plastic window sill, special glue or mortar is used, which is laid out on the work surface immediately after preparation. The board is placed on fresh mortar and pressed down firmly. In order to secure a large-width window sill, mechanical supports are used - brackets screwed with screws. The number of elements securing the board depends on its length and the strength of the material.
• In order for the workpiece to be installed correctly, recesses (grooves) to the thickness of the panel are made in the lower part of the slopes on both sides along the entire length. Marks are made on the slopes, and rectangles are cut out on the workpiece on the left and right sides. Work on creating grooves is carried out using a hammer drill, grinder and chisel. The depth of the recesses depends on the material from which the slopes are finished - it can be a layer of plaster, putty or drywall. Advice! After installation, cracks and holes are carefully sealed with an appropriate composition, which makes it possible to achieve solidity between the surface of the window sill and the finishing of the slope.
• The free space under the plastic panel is filled with polyurethane foam. The foaming mixture increases in volume and can move the workpiece placed in place, so a load is placed on its surface. These could be bottles filled with water, bricks, blocks, even books. The frozen excess foam is carefully cut off with a sharp construction knife.
• At the final stage, the ends of the plastic window sill are closed with plugs, adding completeness and aesthetics. The protective film is removed from the surface of the panel.

Important! Window sills on a plastic window should be fixed horizontally; it is better to take measurements using a building level or square

Decking will help us

A relatively new material for window sills is wood-polymer composite (WPC). Due to its strength and water resistance, it is widely used for the manufacture of outdoor flooring: terraces, balconies, sidewalks (known as decking, or decking board). WPC is produced by pressing wood chips at high temperatures and adding polymer resins. This method allows you to obtain a “board” that is very dense, resistant to moisture and can withstand temperature changes from –50 to +90 °C. And covering the slab with several layers of protective films gives it additional strength and the desired design (there are decors like stone, wood, colored and neutral).

How to level the surface?

Due to improper installation or violation of operating rules, the window sill may become warped. Alignment may be required during installation. You can level it with the following tools:

• perforator;
• polyurethane foam;
• level;
• hammer;
• wooden wedges.

The alignment process consists of several steps:

1. It is necessary to break the wall under the window sill and where it adjoins the slopes - the entire structure must move freely up/down.
2. To level the wedges, you need to place them near the slopes and in the middle of the window. You need to start selecting the size of the wedges from the edges, and at the end move to the middle of the structure. All deviations must be eliminated by checking with a level.
3. The gap between the wedges is filled with mounting foam or cement mortar. There is no need to save on foam so that the structure does not sag in the future.
4. After 12 hours, the remaining foam is cut off, the bottom of the slopes is plastered and puttied.

What determines the price of oak window sills?

The cost of the product is affected by:

• manufacturing technology;
• thickness and length of lamellas;
• window sill configuration (rectangular, corner, with rounded corners);
• brushing (aging effect).

Window sill panels can be spliced ​​or solid-laminated. In the first case, short lamellas are glued together on four sides. The shield looks like parquet, since the timber has a different color.

The second option consists of long slats equal to the length of the shield. Docking is carried out only on the right and left. The wider the beam, the more expensive the product. Standard - from 40-50 mm, wide - from 60-120mm. On average, a high-quality finished product will cost from 16,000 rubles per m2.

If you give preference to a slab, then everything is individual, because there are no identical cuts.
