The interior of the room depends on many little things that must be assembled in one style. This also applies to the window sill, since its presence will give the room a complete look.

In addition to the aesthetic role, a high-quality window sill increases the thermal insulation of the room, and also adds useful space in the house where you can place flowers and other interior items. In this article we will describe in detail the types of wooden window sills and do-it-yourself installation technology.

Purpose of wooden window sills

To more accurately answer the question posed, you first need to determine its main functions:

It protects from cold and wind, but only when the installation is carried out in compliance with all requirements;

The design can serve as an additional space for relaxation, where, sitting comfortably, you can read a book, or contemplate the view from the window, if you make it large enough;

A wooden window sill can be used as an auxiliary workplace by installing a laptop, lamp and other things on it;

It simply creates a cozy and comfortable environment in the room.

Types and sizes of wooden window sills

There are a considerable number of types of window sills. According to the installation method, they are divided into the following designs:

Wide - more than 40 cm. A similar look can be installed if there are massive main walls. Subsequently, it will help save the practical part of the house’s space and skillfully design the radiator;

Narrow in shape, 10 cm wide. Usually done when the type of structure and its specific characteristics do not allow the installation of a window sill of a different size;

Formal look - when there is no window sill as a current one, and instead of it a small segment stands out window slope, not playing an important role;

Launched onto the wall is a common system for installing a window sill, the launch area of ​​which is on average 15 - 20 cm;

Those not mounted on the wall are the most profitable in terms of finances due to the reduction in the length of the window sill.

Shapes and materials for making window sills

There are several forms of wooden window sills:

Traditional or straight;

Having the form of an arc - are original solution to add zest and freshness to the interior.

According to the type of raw materials chosen for the production of window sills, they are divided into the following types:

Low-density wood-fiber panels made from finely dispersed fractions are cheaper than wooden structures and are significantly inferior in quality parameters;

Plastered or made of plasterboard - it is assumed to be finished with tiles or other material;

A wooden window sill is an environmentally friendly option, characterized by durability and versatility. Its production requires observation when selecting raw materials, following installation and maintenance methods, since wood is negatively affected by moisture. To do this, it is recommended to treat it with special impregnations, which allow the wood to remain in good condition for a long time. good condition. That is, it will not lead to cracks, swelling and deformation.

Wooden window sill installation technology

Necessary tools for installing a window sill

To install a wooden window sill you will need the following tools:

Construction level;

Square;

Tape measure for measurements;

Container for soil;

Gun for polyurethane foam.

Step-by-step algorithm for installing a wooden window sill with your own hands

Initially, the dimensions of the planned window sill are determined in order to find out the option and method of its installation.

First, treatment is carried out with moisture-protective substances to prevent early deterioration and increase service life. It is worth paying special attention to the contact points between the wall and the window sill.

The part on which the window sill will be installed must be cleaned of debris, dust, and a primer must be applied. A level is used to position it correctly. The ideal option would be installation on a pre-prepared, leveled surface.

When the material for building a house is brick or panels, the window sill is attached to them using foam. Self-tapping screws are used as auxiliary material for connection. Their length makes it possible to connect the entire area of ​​the window frame and window sill.

When the window sill is wider and protrudes significantly beyond the edge of the window, you will also need to secure it with reliable metal corners or pins inserted directly into the wall. Later it is fixed with polyurethane foam.

If you plan to make a window sill in wooden house, then all actions are carried out during the construction of the window opening itself. Here, if you have a good woodworking machine, it is possible to build a window sill from the opening itself. Otherwise, it is attached using glue or self-tapping screws, the length of which is selected based on the width of the window sill.

Production of wooden window sills

In order to make a high-quality window sill, you need to take the choice of wood seriously. The material must be dried and meet certain standards, have a uniform structure and strength. There should be no presence of blackening or knots.

A pine window sill will be distinguished by such characteristics as durability and reliability due to the presence in it of an impressive proportion of resin that has a disinfecting effect. The most affordable option in terms of cost.

Oak is also a quality type of wood for their production. Its strength properties affect the service life of the product, increasing it. It perfectly resists temperature changes, as a result of which it will not be afraid of a nearby radiator.

Features of installing wooden window sills

Depending on the size of the product, grooves are made from the bottom, and the end parts are carefully polished and ground.

When calculating the size of the window sill, you need to keep in mind that the two sides and the front side are placed in the wall with a recess of at least 4 cm, and on the opposite side it should extend beyond the boundaries of the wall by 6 cm.

To increase the service life, wood material should be painted or varnished. To prevent the appearance of mold, fungi and insects, treat the bottom with a disinfectant.

To minimize heat loss in the future, it is worth insulating the lower part with felt. They need to be secured with nails. Pre-prepared boards are placed on a brick surface filled with a mixture of gypsum and lime. At the window, recesses are made in the wall where these boards are installed.

First, the window sill is installed sequentially under the lower surface of the beam, and secured with ten-centimeter nails without heads. To make it easier, you can first drive in a nail and then place the window sill on it.

When installing it, no tilt is expected. If this happens, then using several wedges mounted in the appropriate place, they are filled with cement mortar. After fixing the window sill, excess mortar is removed and the cracks are filled with foam. After some time, the slopes and scars are plastered, and the window sill is prepared for installation, which can be done immediately after the cement has dried.

Installation of wooden window sills in a wooden house

To install a window sill in a wooden house, it is better to use harder wood species, such as beech or oak, because this type of wood is less susceptible to physical impact.

Unlike other operations required for installing windows, installing a window sill in a wooden house is often considered as an operation performed as part of an interior design project.

This fact determines quite a large number of installation options, as well as an extensive list of materials from which the window sill can be made.

Considering the high versatility of this window frame element, the building materials market offers several dozen alternative solutions, making a choice among which is quite difficult.

In this review, we will look at the most popular models of window sills, their installation technology, as well as the main criteria used to select materials and installation methods.

It is impossible to unequivocally recommend one or another type of material for the manufacture of window sills for windows in a wooden house, since its choice is influenced by various factors, including those determined by the characteristics of the wooden structures.

Let us recall that a tree is such construction material, which, for all its advantages, has one significant drawback - susceptibility to moisture and variability in size.

To compensate for this design flaw wooden house an element such as a casing frame is provided, the task of which is to ensure constant dimensions inside the frame when the size of the window opening changes.

Difficulty of manufacturing finished product depends on the type of workpiece material, as well as on the configuration of the window sill.

Let us remind you that in the manufacture of window sills the following modifications of their design are used:

  • with launch on the wall;
  • without launching onto the wall;
  • with a simple edge;
  • with a curved edge;
  • wide;
  • narrow.

The easiest to manufacture is the option without launching onto the wall, which is most often used in cases where the window sill is made of a plastic profile.

In general, the manufacturing cycle of window sill boards consists of the following stages:

  • determining the type and drawing the outline;
  • cutting out the mounted block;
  • edge formation (for wood)
  • grinding and polishing (for wood);
  • preparing fittings for sealing ends (for plastic ones)

note that wiring diagram PVC window sill can differ significantly from the same operation for a wooden window sill board. This is due to the fact that the preferred method of installing the bottom casing strip is on a tenon, so in some cases, when making a wooden window sill, provision should be made for milling a groove on the bottom plane.

Installation technology

When considering methods for installing window sills, it should be noted that there are two different approaches to solving this problem.

Installing a window sill as a casing element

As mentioned above, in this case the window sill board is in direct contact with external environment(we do not take into account the thermal insulation created by the platbands). Therefore, planting the window sill on the log house is carried out according to the same scheme as vertical racks– “tenon – groove – jute seal”.

Please note that in this case the window sill is installed before the window is installed.

Installation begins by checking the compatibility of the groove and tenon.

Next, insulation is laid on the lower end of the frame, after which the window sill board is laid. Fixation with self-tapping screws in this case is not needed, since the lower casing strip will be pressed by vertical posts.

Separately, we note that the operation of installing a window sill should be considered in conjunction with installing window sills, since without drainage the outer end of a wooden window sill will quickly collapse.

Installing a window sill in a casing with a straight quarter

In cases where the window sill is not part of the casing (for example, when installed on windows in a T-shaped frame with a straight quarter), the window sill is installed after the window is installed.

The board or profile is cut so as to fit closely with window frame. At the same time, the height of the window sill must be sufficient to close the compensation gap (if installation is carried out on plastic windows).

Before securing the board, you must carefully check its position in the horizontal plane. If necessary, the position of the board is adjusted using wedge-shaped pegs.

For fixation, you can use self-tapping screws, the length of which should be such as not to fit into the logs of the log house.

To conclude the review, we will list some features of the window sill installation process, knowledge of which will help you avoid mistakes and unexpected expenses.

Slope

Traditional technology for installing window sill panels suggests that the board being installed should be slightly tilted towards the room. When installing window sills in wooden houses, this rule must be ignored, since mounting on a tenon assumes only the horizontal position of the board being mounted.

Antiseptic protection

If you are installing a wooden window sill, you must remember that of all the elements of the casing, it is the bottom strip that is most exposed to external factors (moisture during cleaning, condensation flowing from windows, etc.). Therefore, thoroughness in this case is not just desirable, but necessary.

Drying degree

Even narrow window sill- This is enough wide board, which is always at risk of warping due to changes in its internal humidity.

To prevent this from happening, lumber used for the installation of wooden structures in contact with the internal environment of the room must be dried to a level of 12% residual moisture.

The Master Srubov company will provide professional finishing of log or timber log house to a state of complete readiness for finishing, including installation of window sills and slopes. You can clarify the details of cooperation and order a visit from a specialist via e-mail or by phone numbers posted in the section.

Installing a wooden window sill is important not only from an aesthetic point of view, but also from a functional one. Products are made from various types of wood and its derivatives, different sizes and depending on the purpose of the room. Self-installation will not be a problem if you know the main stages and treat the work with full responsibility.

You can make a window sill from any type of wood, the main thing is to decide for what purpose and where this interior detail will be installed. Hard wood, such as oak, is resistant to moisture and temperature changes and has a long service life, but the cost of such a product will cost a pretty penny. This material is suitable for window sills that will be used as working area or stands for heavy flower pots.

A budget option would be pine or spruce. Window sills made from these species are easy to install and do not require antiseptic treatment due to their increased resin content. You can install a larch board. It is not as expensive as oak, but has the properties coniferous trees. The shade of a larch window sill turns out to be more noble, which determines its demand among buyers. There are several criteria for choosing wood for installing a wooden window sill with your own hands:

  • integrity of the board. There should be no defects (chips, cracks, knots, etc.) at its ends, as well as inside the wood structure itself;
  • The type of wood must be strong. It is better to choose oak, beech, hornbeam. Less strong are larch, pine, chestnut, cedar, but they have a beautiful pattern;
  • texture and color of the board. There are so many species, so many shades and patterns of wood you can find. The choice depends on individual preferences and interior design.

In addition to solid wood, laminated wood, chipboard and MDF are used. Unlike solid wood, glued boards do not deform from moisture, are much cheaper, but look no worse. If you want to save even more, it is better to give preference to MDF or laminated chipboard. The raw material is pressed wood shavings, covered with laminate on top. The material is also good because it has many options for textures and shades. With its help, you can give the window sill the look of marble, stone, with a matte or glossy surface.

If you approach the choice of material for the window sill with all responsibility, then in addition to the functional element, you can get a real decoration for the room. Already on sale finished products, or you can try and do it, and then install the wooden window sills yourself.

Necessary tools and materials for installing a wooden window sill

Before installing a wooden window sill, you should preparatory activities. First of all, you need to prepare the tools and materials:

  • window sill board (finished or made yourself);
  • building level;
  • square and ruler;
  • measuring tape;
  • polyurethane foam and a gun for it;
  • marker;
  • solution container;
  • brushes and rollers;
  • pegs or bars to regulate the installation of the window sill.

Check that you have all the accessories so that you don’t have to look for them while working.

Preparing walls before installation

Installation of wooden window sills begins with preparation. The surface on which the window sill board will be laid requires special attention. Surely, after installing the window structure, there was excess cement, dust, and other construction debris left behind. The surface must be thoroughly cleaned from them. The side parts are tapped. This is necessary to ensure that the board is firmly fixed in the wall. For better retention, it is better to “recess” the window sill into the slopes to a depth of 1-2 cm. If metal corners are encountered when making recesses, they must be carefully cut with a grinder and removed with a chisel.

Primer and water are applied to the cleaned wall. If there is a recess under the base in which communications pass, then horizontal supports made of metal or wood are placed on top of it to hold the window sill.

Window sill leveling

According to the construction rules, 2/3 of the window sill plane is located on a hard surface, and the rest is left in the form of a canopy. The maximum protrusion beyond the wall should not exceed 7-8 cm. If this point is violated, then subsequently the heat exchange in the house will be disrupted, and condensation will form on the glass.

Most homes aren't perfect. smooth walls. The base for the window sill is no exception. The surface is leveled and checked using a level. If there are even small errors and distortions, they are eliminated using wedges. The window sill may not be installed perfectly level. The standards allow a slight tilt, just a few millimeters, of the boards forward. After the window sill board is placed on the wedges, the angle of inclination is checked again with a level. It should be the same over the entire area. After this, the board is removed and the wedges are fixed on the surface using cement mortar.

Window sill fastening

Before installing a wooden window sill, you need to treat its surface, especially at the point of contact with the wall, with a moisture-proof compound. This will prevent its premature deterioration and rotting. A cement mortar of such thickness is applied to the base that it rises 5-8 mm above the level of the wedges. In addition to cement, you can use putty or gypsum, but traditional mortar will hold the structure more firmly. The window sill is laid on cement and pressed against wedges. Excess mortar that appears is removed with a spatula, but before it sets. If there are doubts about the quality of impregnation of the window sill with a moisture-repellent agent, a polyethylene film.


You can install a wooden window sill not only if the window structure is also made of wood, but also in combination with plastic. The market offers big choice shades and with the right approach to choosing colors, a wooden window sill board will harmoniously combine with plastic window. In addition, a wooden element will add zest to faceless plastic and create individuality in the room.

Reinforcement and sealing

If laying a wooden window sill with your own hands is carried out in a panel or brick house, then it can be laid on polyurethane foam. After it hardens, the protruding residues are cut off. For additional strengthening, with outside window sill and window frame secured with self-tapping screws. At the same time, it must penetrate through the entire window structure and enter the rear edge of the window sill by no less than 4 cm. Thus, both vertical and horizontal stability are achieved.

A wide window sill, which protrudes significantly beyond the lower window slope, also needs to be additionally secured. To do this, metal corners or wooden blocks, secured with self-tapping screws. You can use pins that are mounted into the wall under a slope. First, holes are drilled for the pins in the window sill board itself. Only after these manipulations carry out installation wooden element on foam. Keep in mind that the installation of a window sill in a wooden house should be carried out at the stage of installation of the window block itself.

At the end of the installation process, you need to seal all joints and small cracks at the point of contact between the frame and the window sill. This is done using acrylic. It is more plastic and resistant to negative influences.

Installing a wooden window sill with your own hands is not as difficult as it seems at first glance, but still requires some experience. If you are not confident in your abilities, and there is an opportunity to ask for help, it is better to leave this matter to professionals.

The peak of fashion plastic window sills passed unnoticed. The needles of the barometer called “Fashion Trend” moved towards Natural Wood window sills and froze. It’s a pleasure to install ready-made window sills from the manufacturer: sprinkle with polyurethane foam, lay down the window sill board, and now the installation is almost complete. However, it is necessary to skillfully work with polyurethane foam and install the window sill.

Choosing a wooden window sill

Comfortable and practical wooden window sills give a finished look to the interior of the room and the window. By installing a solid laminated wooden window sill, you can create cozy atmosphere bedroom, living room or office.

In addition, skillful installation of a window sill according to all the rules will improve the functionality of the structure when glazing, for example, a loggia.

window sill view

As part of a window block, a window sill board can be:

Wide or narrow

With or without wall launch

Rectangular in shape or have rounded (radius) corners.

But the main selection criterion is still the quality of the wood.

wood

When choosing a wooden window sill, you need to pay attention to the type of wood, correct installation And daily care behind the surface.

The most preferred choice is oak window sills. Pine and beech wood is also suitable for window sill boards. It is preferable to choose glued pine window sills, which are least susceptible to warping due to temperature changes.

dimensions

According to the technology for installing window sills, only 1/3 of the board should protrude beyond the wall. Therefore, the conditionally recommended width can be 20-25 cm. No one can prohibit the installation of a wide window sill. However, this will require additional strengthening of the structure and, accordingly, fastening. Classic sizes window sill made of wood is: length 1.50 m, width 250 mm, thickness 40 mm.

Methods for mounting and installing a wooden window sill

There are several ways to install wooden window sills:

On a cement screed

Using special glue

On two-component polyurethane foam.

The installation technology and installation methods are identical. The difference lies in the use of mounting solution. The choice of installation method depends on the working base of the window and the material of the window.

There is no single standard for the installation of wooden window sills, but the recommended standard 30971-2002 assumes resistance to heat transfer, sound insulation and resistance to deformation of mounting and expansion joints relative to the window opening and walls.

Naturally, before starting the installation and installation of the window sill, it will be necessary to carry out a number of preparatory measures.

We carry out step-by-step installation

Step-by-step instructions for installing wooden window sills will consist of the following steps:

Preparing window sill boards for installation

Preparing the installation base

Laying and aligning support strips

Marking the board for fastening

Application of mounting mortar (cement screed, glue or foam)

Installing a window sill on a mounting solution

Creating a compensation gap between the window sill board and the wall

Installing spacers between the installed window sill and the top of the window

Applying sealant to the expansion gap

Removing the spacers.

preparing the window sill for installation

Before installing the window sill, it is necessary to treat it with a moisture-proofing compound. The window sill board and areas adjacent to the window opening and walls are subject to treatment.

preparing the base for installation

Before installation, the surfaces of the base and window opening are dust-free and primed. Window seams are foamed.

The installation of wooden window sills is carried out on a dry, rigid base, filled with screed or on bars in increments of 80 cm. A prerequisite is that the window sill is inserted into the wall 2-3 cm on both sides. Therefore, it will be necessary to perform wall gating.

laying and aligning support strips

The recommended height of the screed or supports made of bars should ensure that the edge of the window sill fits into the profile without a gap. For example: for a window sill with a thickness of 40 mm, the permissible gap from the screed to the support profile should be about 50 mm.

applying mounting solution

For the mounting solution for installing a wooden window sill, you can use: cement screed, adhesive mortar and two-component polyurethane foam.

Wooden window sill panel or brick house It is recommended to lay on foam. For concrete base use dry mixtures cement screed And adhesive solution.

laying cement screed and adhesive mortar

The preparation of cement mortar or adhesive mixture is carried out traditional way. The solution is applied to the base using a spatula.

The height of the applied solution should be higher than the level of the laid out bars. After pressing down with a window sill board, the solution is distributed under the weight of the window sill. When installing, you must remember that the window sill has a slight slope (3 degrees) into the room.

applying polyurethane foam

Installation on two-component foam is a simple process that can be mastered in a few minutes. Shake the foam container for 2 minutes before applying, then use special devices The socket of the balloon is directed to the application site.

The distribution of the released foam is controlled using nozzles. You can apply the foam using a zigzag motion. After applying the foam, it is necessary to quickly install the window sill in place, because the hardening time of the foam is minimal.

creating an expansion gap

Wood has the properties of changing volume under the influence of temperature and humidity changes. Therefore, when applying the mounting solution, it is necessary to remember the need to create an expansion gap.

To do this, install a damper plate 3-5 mm thick between the window sill board and the wall. After the installation solution has completely dried, it is removed and the seam is protected using sealant.

During the hardening process of the mounting foam, adhesive mortar or cement screed, the position of the installed window sill can be changed. It is possible to eliminate the occurrence of deformation between the window sill board and the top of the window block by installing special spacers.

The resistance of the spacer area to the forces of swelling of the foam or screed ensures perfect option window sill installation.
