The window is flush with the wall. Correct installation of window sills. Recessed structures

A plastic window provides high-quality isolation of the interior space from the street, but only if installed correctly. Errors when installing plastic windows negate the efforts made and money spent.

The production and installation of plastic window openings is a complex technological operation; it can only be performed by experienced specialist. However construction market filled with fly-by-night companies and unprofessional workers. It’s good if a window manufacturer was recommended to you by friends.

It's good when you are confident in the quality of the work being performed. But what to do if you found the manufacturer of double-glazed windows through an advertisement or were recommended to you by people you don’t know? Here is a list of criteria that will help you evaluate the quality of window installation and promptly detect mistakes made.

Error in matching geometric dimensions

The most common mistake made when installing plastic windows is incorrect measurements. Ideal window opening measurements are made during the construction process by measuring empty window openings.

In reality, plastic windows are often used to replace old (wooden) frames. In this case, measuring the opening becomes more difficult, since old frames take up space and make it difficult to estimate the dimensions accurately. Incorrect measurements will lead to incorrect geometry of the finished frame and glass unit. How to evaluate this at the stage of installing plastic windows?

The gaps between the plastic frame and the wall should be 3-4 cm. At the bottom, the gap may be larger, taking into account the required slope of the external ebb. Gaps that are too narrow will not cope with thermal expansion (with a plus, the plastic expands, with a minus, it contracts).

The frame rests against the wall, causing curvature. This will affect the decrease in durability, and possibly the appearance of cracks in the glass unit. In addition, the narrow gap is difficult to fill with foam. Because of this, unfilled holes remain, which will disrupt the tightness of the seam.

Too large gaps will not provide sufficient fastening of the frame to the wall; the structure will be shaky and unsafe.

Is it possible to fix the error? Sometimes yes, more often no. If deviations from the required dimensions are small and are directed towards reducing the width or height by a few centimeters, they can be compensated for with polyurethane foam. In all other cases, it is necessary to manufacture new plastic windows.

Errors in the slopes of frames and double-glazed windows

Window measurement - typical diagram.

The frame and glass unit must be installed strictly vertically. The correspondence of the frame position to the verticals and horizontals is difficult to assess visually. Only significant tilts or shifts are visible to the naked eye. Small slopes (1-2º) are unacceptable in the installation of plastic windows, as well as significant deviations.

To evaluate horizontals or verticals, a building level is used. This tool looks like a large ruler. There are capsules with air bubbles on the side and in the middle of the ruler. The ruler is applied to the surface of the frame, and the location of the air bubble is visually assessed. When the surface is horizontal, the bubble of the side capsule is located exactly in the middle. The displacement of the bubble in any direction indicates that the frame is tilting to the right or left.

To assess the vertical, look at the capsule located in the middle of the ruler. It also has an air bubble, and it should also be in the middle.

Measurements are performed for three levels:

• horizontal frame (a level is applied to one of the horizontal parts of the frame);
• verticality of the frame in the plane of installation of the double-glazed window (the level is applied to the vertical part of the frame);
• no tilt of the frame inward or outward (the level is applied to inner surface vertical frame element).

Another way to visually assess the vertical installation of plastic windows is as follows. You need to open the window various options(open from the side or open with a window at the top) and leave, without holding it, in the open position. If there are no installation errors, the sash should not change its position and be in the same place where you left it. A persistent movement of the sash towards closing or, conversely, towards opening indicates an existing misalignment.

All of the above measurements are performed by the worker. The owner (customer of the work) only needs to come up and make sure correct position air bubble in the capsule.

What is the danger of non-compliance with spatial geometry? Even small deviations (1-2º) lead to a shift in the center of gravity and improper distribution of load in the structure. As a result, after some time the frame will warp. A sign of a misalignment is that the window is difficult to open (or it is not possible to open it at all).

Error - insufficient installation depth

Insufficient distance between the double-glazed window and the outer surface of the wall will result in the windows getting wet in winter. This occurs due to the condensation of warm air on the cold glass of the window. If plastic construction located close to the line outer wall(at the same time, the outer window sill is narrow), the glass from the outside is exposed to sub-zero street air.

The outer glass is cooling. The cold is transferred to the inner glass. Following it, the warm air of the interior cools down. When warm air cools, moisture drops out of it. Drops of water condense on the cold surface of the glass and frame, flow down, collect in puddles on the windowsill, or are absorbed into things near the window (books, toys, phones). Similar processes occur when brought into the house from the street. glass jar. It quickly fogs up (becomes covered with small drops of water).

Condensation, or wetting, of windows does not occur if the glass unit is correctly positioned from the line of the outer wall. Installing a window in a recess of at least 1/3 of the wall thickness significantly limits the entry of cold air into the glass and frame. There is no cooling of the air layer along the glass unit - no condensation drops.

Some owners mistakenly believe that the process of condensation and wetting of windows occurs only in household premises. This is wrong. In domestic rooms (kitchen, bathroom), moisture condenses much faster and windows get wet more often. Window getting wet living rooms appears more slowly because the air contains less water vapor.

You need to know that any air contains a certain amount of water vapor. Thus, in the space of a residential apartment, the air humidity is 30-60%; with an increase in the number of people in the room, the humidity increases (a person constantly exhales carbon dioxide and water vapor). There is no absolutely dry air in rooms, therefore, wetting of windows is determined not only by the humidity of the room, it occurs when wrong depth installation and lack of ventilation.

Errors in frame fastening

The frame is attached to the wall using special mounting plates. Their number on each of the four sides should be at least two, with a total of eight on one window. The lack of fastenings impairs the stability of the window structure and increases the possibility of it falling out in emergency situations: there is a strong hurricane wind or a child leans his back on the window. Even in the absence of force majeure, the lack of fastenings will affect their warping. Over time, the window will sag, become warped, and stop opening.

The lower window frame is installed on so-called stops or lower blocks. After filling the gap with foam, the pads are not removed. They bear the main weight of the structure.

And now the most the hard part checks. You need to look at what is used to secure your windows to the wall. Possible options- using a plate or using a bolt. Both methods of fastening window frame in the opening is used in the installation of swing structures. But with reservations.

Bolt (called anchor bolt) drills the profile completely, this happens with any rod fastening. The plate (called an anchor plate) is attached to the end with a galvanized self-tapping screw. In this case, the closed space inside the profile is not disturbed, the frame is not drilled, and the strength and durability of the profile are not reduced.

The length of the anchor bolt should ensure the strength of the installation of the structure. The rod is recessed into the wall by 4 cm, plus the width of the frame is 4 cm, plus the distance between the frame and the wall is 4-7 cm.

In what cases is it important to check how the window is attached to the wall:

• if you are installing aluminum warm profiles;
• if your wall contains internal insulation.

Inside aluminum profile There is a layer of thermal insulation. Drilling such a frame will lead to loss of thermal insulation properties. An experienced master should know this feature.

In a multilayer wall, the heat insulator can be inside (between the inner and external masonry) or outside (on a supporting wall, covered protective layer). The internal location of the insulation does not allow screwing in the anchor bolt, since there is low-strength insulation in the middle of the wall. Attaching plastic windows to the opening of a multilayer wall is done only with anchor plates.

Invisible doors are successfully used in any type of interior, in particular in offices and apartments in a minimalist style.

Design solutions

It's no secret that technical excellence modern materials and fittings allows you to create any engineering solutions. One such product that can literally take you back to childhood is invisible doors. This is a sash installed flush with the wall. When applied to the surface with a finish similar to the walls, interior passages literally disappear, and the use of hidden handles enhances the effect.

In addition to the fact that such doors return the atmosphere of childhood with hidden rooms, secret passages, and so on, they are capable of completely solving specific tasks on space manipulation and more.

Changing the layout in a small apartment area. In this case, quite often there is a need to form clearly defined thematic zones. Then the presence of a doorway can spoil the picture and prevent you from creating a space with the desired design. An invisible door solves this problem by hiding interior passages, making the visual perception of a solid wall.

Fans of minimalism will also find invisible doors a successful element for interior design. Such interior designs are distinguished mainly by their compliance with style. Commonly used smooth canvases made from various materials.

To create a bright and modern design rooms even in abstract style invisible doors are very useful. Here the factor of their installation comes first. The canvas is flush with the wall, the box is completely hidden, the surface can be painted in any color or covered with any finish. There are ideal opportunities to incorporate such an element, to make it part of any abstract painting or neat geometric design of a wall area.

Interior products of this type are useful in offices. This is very convenient way change the space, get rid of the clutter of entrances or hide unexpected interior passages, storage rooms and other service areas.

There are other, more unexpected uses. It all depends on the designer’s imagination. You can place shelves on the canvas, hang pictures to completely hide the entrance to the dressing room, or create a separate work area, completely isolated from the rest of the environment.

Design solution

One of the structural installations

If you look at the market offers, you can see that the price of ready-made engineering solutions is quite high. This is explained quite simply.

Modern serial invisible cameras are made of metal. This is the easiest way to make a durable solution that meets any requirement. If we consider a short list of wishes for which users choose such designs, it will look something like this:

• Possibility of installation flush with the wall;
• perfect closure, the structure should be invisible on both sides;
• the canvas must have high strength so that any finishing can be applied to it, for example, pasted over with decorative stone;
• the fittings must be hidden and ensure reliable long-term operation even in conditions of strong changes in the mass of the sash.

Such rather stringent requirements form the picture of the market. The price is high, since solutions are used that provide a margin of safety, reliability, and also guarantee long service life:

• load-bearing structural elements are made of metal, most often a lightweight and durable aluminum profile is used;
• the elements of the box, which are responsible for rigidity, are moved beyond the plane of the opening;
• the door leaf is also formed according to the rules for the manufacture of steel products; it is taken into account that exterior finishing cannot be responsible for strength, since it can be any;
• fittings are used, in particular, hidden hinges, designed to control a sash that weighs much more than the actual weight of the finished leaf;
• serial solutions are immediately designed for invisibility on both sides, so the concept of a cover strip almost disappears, it is replaced by a metal corner.

All finished products are calculated for a certain wall thickness. A structure of any thickness can be made to order, and the price increases accordingly. But for the money the user gets a truly high-quality solution.

Finishing methods

Painted and decorated to match the wall

You can use any materials to decorate the door leaf. Ready-made solutions are typically offered in adhesive finishes for subsequent paint and adhesive coatings. The following materials are common among production models:

• veneer;
• acrylate, a thick, highly durable plastic that is scratch and abrasion resistant;
• glass;
• thin overlays made of wood or MDF, often pre-primed, intended for subsequent painting or wallpapering.

In cases where glass and acrylate are used, there can be any colors, as well as light refraction effects. Coatings intended for subsequent finishing allow the application of decorative plaster.

Simple solutions

Price ready-made solutions raises the question of creating an invisible door with your own hands. Despite the apparent complexity of the task, it is quite doable if certain conditions are met.

Interior doors, invisible on one side. The finished design can be easily modified with your own hands. It all depends on the thickness of the box and the location of the door in it. In the case when the canvas is closed state is located flush with the power beam of the box, the amount of work is minimal. You need to replace the hinges with hidden ones, which will require a little work with a milling cutter. After this, the box is installed in such a way that the right side the door was flush with the wall. Platbands are not installed.

When the canvas goes deep into the box when closing, the amount of work done by hand increases. The easiest way is to disassemble the box - you will need a little patience and accuracy. After this, on a carpentry machine or using a plane, the excess thickness of the power beam is removed so that the canvas is flush when closing. This can be done with your own hands, if you have free space - even at home. After this, the box is assembled, and the procedure is similar to that described above.

If you don’t want to reduce the thickness of the box, you can move the canvas, but you will have to increase the width of the cover strip.

Invisibility on both sides. If you want to get a door that is invisible from both sides, the task will become much more difficult. There will be two obstacles on the way:

• the thickness of the canvas will never be equal to the thickness of the wall;
• the door frame is not made of metal, so a door strip is necessary, in addition, it must be strong enough.

To make a door invisible on both sides with your own hands, you will need to change the thickness door leaf. If the door frame structure and it is possible to remake the frame; you can remove the overlays, assemble a new base and glue the removed parts onto it.

You only need to make recesses around the perimeter into which the counter strip will fit. After which the box and the canvas (after replacing the hinges) can be mounted in the opening.

If the door is not of a frame structure or inserts are used, the complexity of the work increases by an order of magnitude. In fact, we are talking about making a new door leaf. You can do it yourself, but you need skills, equipment, and materials.

Invisibility products – popular and convenient solution. If you don’t have enough financial resources, but want to get such an interior detail, you can make a one-sided invisible structure with your own hands. In other cases, it is better to use ready-made engineering solutions. They are easy to install and look great.

PVC windows are much cheaper than wooden euro-windows. But in the current time of total price increases, even this amount seems unaffordable to many. Do-it-yourself installation allows you to save on replacing windows. How to install plastic window yourself?

When to bet

When choosing the time to install a plastic window, you should pay attention to:

If you order installation from a construction company, it is better to do it in winter. Firstly, prices are lower (the peak of orders occurs in autumn and summer). Secondly, the quality of installation is immediately obvious: it blows or it doesn’t blow.

If you decide to install a window yourself in winter, be careful when choosing polyurethane foam. It must be designed to operate at sub-zero temperatures.

Measurements and model selection

How to measure a standard window without quarters: the width is measured along the inside of the opening between the slopes, the height is measured from the top slope to the window sill.

When calculating dimensions, you need to add the value to the width installation gap on both sides, to the height - twice the size of the gap and the height of the stand profile. Measurements should be taken in two or three places for both width and height, and in both cases choose the smaller number.

Quarter window (these are often found in brick houses). Measurement is made according to outside window. Width is defined as the distance between the quarters plus twice the overlap of the quarter on the window (up to 4 cm), height - the distance from the top quarter to the low tide plus the overlap of the quarter (up to 4 cm). Under the window sill and ebb there is usually cement strainer, due to it you can increase the glazing.

The optimal window installation depth is approximately a third of the width of the opening wall from façade wall. This distance should not be shortened. Moreover, it is not recommended to place the window flush with the facade: it is coldest here, in winter period Condensation on the glass is guaranteed.

Installation technology

Before installing a plastic window yourself (a day before), it is recommended to fill the internal space of the stand profile with polyurethane foam to eliminate the possibility of a cold bridge forming along this line.

Installation diagram of a plastic window

The old window is dismantled on the day of installation. All opening sashes are removed, the frame is sawed through in several places and torn off using a crowbar. Remove the ebb and window sill. It is also advisable to break up the old plaster slopes and redo them after installation.

Before starting installation, it is recommended to remove the sashes from the new window and remove the double-glazed windows so as not to damage them during the installation process and to make the window structure extremely light. To do this, you must first pry up the glazing beads with a thin spatula, remove them, then remove the bag itself.

Attention: it is advisable to mark the removed glazing beads, because... they may vary in size.

How to install a plastic window yourself:

1. Drill with inside frame holes for mounting anchors. At least three points on the sidewall, at least two on each horizontal line. You need to drill with a metal drill, because... metal reinforcement is located under the plastic profile cladding. The hole diameter is 8-10 millimeters (in accordance with the size of the anchor).

2. Place several backing bars on the lower slope of the opening and install the frame on them. Align horizontally and vertically by driving bars between the frame and the walls.

3. Drill holes in the walls of the opening through the holes drilled in the frame.

4. First, attach the frame from below. Check the location again with a level and plumb line.

5. Insert the side and top anchors and tighten the fasteners.

In a similar way, you can install windows yourself and use mounting plates that have holes for fastening. First, the plates are attached to the frame. Next, install and align the frame as described above. Unfold the plate so that part of it rests on the frame, and part on the slope. Attach screws, check once again for correct installation and tighten the screws.

Once the frame is fastened, the gaps are foamed. After the foam has hardened, trim off the excess. Be sure to seal the seams on both sides with waterproofing tape to prevent the foam from being destroyed by moisture and ultraviolet radiation.

The window is installed. All that remains is to design the internal slopes, install the platbands and the window sill.

Features of installation in timber

Peculiarity wooden houses– shrinkage. Shrinkage wooden structures give throughout life, and not just in the first year, like concrete ones. As the walls shrink, they exert uneven pressure on the plastic window structures and deform them.

To prevent this from happening, install windows (see photo) in wooden houses made using a frame - an additional wooden frame with movable vertical posts. It protects not only the windows from deformation, but also the facade beams themselves from horizontal displacement.

Installing windows in a timber house is done as follows:

1. From wooden beam make two blanks according to the height of the opening.

2. A tongue-and-groove fastening is cut out in the workpieces and slopes. Typically, a groove is selected in a wooden beam, and a ridge is cut out in the wall of the opening.

3. Cover the ridges with a layer of felt. Put on the stands. Their location must be strictly vertical; this should be taken into account when preparing the tongue-and-groove lock.

4. Two horizontal blanks are made along the width of the window. Grooves are selected at their ends to align with the racks.

5. Lay the lower part of the frame. Combine with racks, measure horizontally. If necessary, place wedges.

6. Install the upper vertical in the same way, leaving a gap between the frame beam and the wall.

7. The gaps are filled with tow or felt (not polyurethane foam!).

8. A window is placed in the resulting frame as described above.

Now when shrinking vertical bars will slide along the slopes, and she wooden frame it will retain its rectangular shape.

Features of installation in aerated concrete

Installing windows in aerated concrete has its own characteristics, which are determined by the specifics cellular concrete. Additional designs not required, installation sequence is standard. There are several nuances:

1. Fastening is carried out with dowels for aerated concrete. Nails and other similar fasteners are excluded.

2. A hammerless drill should be used to make holes. The holes are slightly larger than the immersed part of the dowel. The distance from the edge of the opening is at least twice the depth of the holes.

3. Three-layer sealing of the installation gap: on the outside there is a waterproofing tape placed on an adhesive-sealant, in the middle - polyurethane foam, on the inside of the seam - vapor barrier tape.

Now you know how to install a plastic window yourself. If it seems difficult, hire professionals; if not, feel free to proceed and do it conscientiously.

Covering a house with siding yourself is quite simple. For such work you will not need to master any special skills. It is necessary to prepare thoroughly in advance. The quality of the result depends on how well all the subtleties of the process are thought out. The work includes not only the installation of panels, but also cladding ground floor and windows. That is why a beginner, when faced with the need to perform such work, often finds himself in a dead end. To understand the cladding process, you will need to read the step-by-step instructions for finishing a window with siding yourself.

Methods for finishing openings

When creating an attractive window treatment, the type of window installed makes a huge difference. It depends on what technology will be chosen for installing siding panels. There are several types of installation of double-glazed windows:

In each of these cases, finishing is carried out even before fixing wall panels, which will be located around the window. In this case, the edges of these elements simply need to be inserted into the groove on the edge of the profile. When performing finishing after installing the panels, the work will cause certain difficulties.

The installation technology is common to all siding panels. The screws should be tightened in the center of the mounting holes. In this case, a gap of 1 mm should be left for cases where thermal expansion will occur. This way the panels will move freely without deforming. If you follow this rule, installing siding panels on the window will be much easier.

Features of window siding finishing can be found in the video:

Attention! According to the instructions, during installation you can fix the elements in arbitrary places.

The sheathing bars must be fastened around the perimeter of the window. Small planks are installed on the slope. This will make it easier to install the finishing profile. The bars must be the same size. This will make the wall surface more even. All work is carried out with a level.

Preparatory stage

High-quality window finishing from the outside requires certain preparation. Such work includes:

• removal of decorative elements;
• cleaning the surface from old plaster;
• removal of old wooden parts;
• dismantling of communications.

In addition, technical devices and fixtures - antennas and air conditioners - are also removed. The surface is cleaned and dried. It is better to carry out such preparation if it is planned to cladding the entire façade of the building.

Frame installation

When deciding to decorate a window opening with siding, it is worth considering that before such work, lathing should be done. It will be needed for the following reasons:

• so that the material is securely fastened;
• it will be much easier to perform cladding;
• to level the surface of the wall.

The following options are suitable for lathing:

• wooden beam with a cross-section of 4x6 cm.
• metallic profile.

Advice! When using wooden beams, before starting cladding, it is necessary to treat the elements with an antiseptic. This will help prevent the wood from rotting and being damaged by insects.

The frame parts are attached at a distance of 20 cm from each other. This step is optimal. If it is larger or smaller, the strength or aesthetics of the structure will decrease.

Insulation

Finishing windows during siding installation involves creating an insulating layer that will protect the window frame and the room behind it from the effects of cold. It is better to perform insulation polystyrene foam boards. It is mounted on dowels with wide heads.

Advice! To protect the insulation from moisture, a film should be laid on top.

Since cracks cannot be avoided during installation of the window frame, it is necessary to prepare the sealant in advance. Thanks to the use of this material, it is possible to increase the hydro- and thermal insulation properties of the structure as a whole.

Window finishing technology

For each of similar cases actions may have different orders. Separately, you should familiarize yourself with the decoration of windows without slopes. Siding in this case includes the use of special platbands.

Advice! For greater reliability, the elements are sealed with sealant.

The panels are cut at the top and bottom of the window structure. The slot should be slightly narrower than the width of the window strip. Learn more about siding technology window designs from the video:

Recessed structures

Window trims are great in cases where the window is not very deeply recessed into the wall. Thanks to the use of planks, the slopes are closed.

Then the window strip is placed in the hole finishing profile. When joining the planks on the vertical elements that connect to the slope, it is necessary to make special cutouts. Horizontal elements are cut and bent.

If the window is recessed quite deeply, the use of window strips is not required. For such structures, small pieces of wall panels are used. During the installation process, a corner is used.

Installation can be carried out using a special ebb. Its edges must be trimmed and folded under the vertical elements. To increase the reliability of fastening the ebb, a sealant is used.

Installation of siding on windows is carried out in the following order:

• first, a J-profile is attached around the perimeter of the structure;
• then the installation of pre-prepared elements of the frame panels is carried out;
• At the final stage, the corner profile is installed.

During installation, you must follow the same rules as for the general installation of siding panels. Each connection should be created with a gap of 5 mm.

Attention! When performing work in autumn or winter, the gaps should be increased to 10-12 mm.

Arched windows

Such designs look great, but finishing them is fraught with some difficulties. Installing siding on arched windows is complicated by the presence of a curved part in the upper part of the structure.

For finishing, a J-profile is usually chosen, which is quite flexible. However, its cost is significantly higher than that of a regular one. For this reason, its standard counterpart is often chosen. To do this, several cuts should be made in a regular profile, which are made on the mounting part. It is then bent to give the required radius of curvature.

Attention! In some cases, cuts are created with front side products. If carried out carefully, this solution will become an effective design technique.

An alternative option is to replace the arched opening with a polygonal opening. The design of such a window is performed using the same technology. However, the profile cutting will be large.

The ease of bending a regular J-profile will depend on the material from which it is made. In the case of metal, it will yield much harder than plastic. To create an arc of the required radius of curvature, select vinyl siding. To make bending easier, it should be warmed up well. However, do not overuse this - the plastic can easily melt.

conclusions

The overall impression of the facade of the house depends on how well the windows are finished. That is why such work should be treated with the utmost caution. The installation technology is determined by the shape of the window, as well as the degree of its recess into the wall. Such work will be simple even for a novice builder.

If you follow the suggested tips, finishing a window with siding will not be difficult, and the result will be pleasing to the eye.

Before facing it is better to take care of proper preparation opening. It should be cleaned thoroughly. For guard interior spaces from the cold it is necessary to create a thermal insulation layer. It is made from polystyrene foam boards.

At correct execution When covering windows with siding, decorative elements will not be deformed under the influence of temperature changes and weather conditions. The process of finishing a window with siding can be learned from the video:

The role of the window sill cannot be overestimated. After all, this is not only decorative element windows and rooms. The window sill participates in thermal insulation, preventing the penetration of cold air from the street. Therefore, installing this window element is a process that requires accuracy and strict adherence to the rules. This article is devoted to the installation of window sills.

What is window sill board made of?

The materials from which window sills are made today can be different. The type of window sill board determines the method of its installation.

Wood, such as oak, cherry, pine, for a long time was the most common material from which window sill boards were made. Wooden window sills do not lose their connoisseurs to this day. The wood is pre-dried and treated with antiseptic solutions and varnish.

The main advantage of a wooden window sill board is its natural origin and noble appearance. But such material is expensive, and solid wood products are subject to deformation. To preserve the window sill, you need to protect it from exposure to abrasives, water and aggressive chemical reagents, and also periodically update the coverage.

Boards made of laminated veneer lumber are less expensive and more resistant to external influences if they are made in compliance with the technology.

Chipboard and MDF

As a cheaper alternative to wood, many companies produce window sill boards made from chipboard or fibreboard. The products are covered with a special film on top. MDF is a more durable and moisture-resistant material compared to chipboard. If the integrity of the film is damaged, water that gets onto the slab from chips can lead to swelling and significant deformation. MDF is more expensive, but more stable.

Window sills made from wood chips or fiber are very easy to clean. The main thing is not to use abrasives.

Stone products

Connoisseurs natural materials stone window sill boards are often preferred. Most often it is granite or marble. Stone products are beautiful, each window sill has a unique pattern. But this pleasure is not cheap.

Moreover, on polished surfaces natural stone easy to leave a scratch. Stone window sills easily absorb dirt, such as coffee, wine or tea stains. And their thermal insulation is weak. Due to high cost and heavy weight, it is better to invite professionals to install a stone window sill.

An alternative to a natural stone window sill is a board made of artificial stone acrylic based. Such products are not inferior in strength, heat resistance and beauty, but at the same time they are cheaper and do not scratch.

PVC products in construction are becoming increasingly popular every year. This also applies to plastic window sills, which have a whole list of advantages.

PVC window sills also have disadvantages:

• non-natural origin of the material;
• laminating film that performs decorative role, may peel off and be easily scratched;
• High temperatures, such as a hot pan, can cause the window sill to warp.

Nevertheless, plastic window sills Most often used for installation on your own.

How to mount a window sill

All window sills are installed according to general principle. Since plastic window sill boards are often preferred for DIY installation, we will describe in detail step by step instructions specifically for PVC window sills, noting at the end the features of installing structures made of other materials.

Before buying materials, it is necessary to correctly measure the place where the window sill will stand. The length of the window sill is determined as follows:

To determine the width of the window sill, you need to measure the width of the wall to the window. To the result obtained, add 1.5 - 2 cm to deepen the board into the window groove. This width is sufficient if you plan to install flush with the wall, which is feasible for smooth walls.

Note! When the walls are uneven, it is recommended to measure them on both sides of the window. This will allow you to adjust the window sill and install it evenly.

You can provide a protrusion, the size of which should not exceed 8 cm, so as not to interfere with the convection of air from the battery. After all, this will not only disrupt the uniform distribution of heat in the room, but also in cold weather will lead to damage to the window as a result of the formation of ice.

In accordance with the measurements obtained, the window sill is adjusted according to required length and width. Now you can begin installation.

Window sill installation

Step 1. Try on the future window sill at the installation site. Trim the board if necessary.

Note! It is recommended to cut plastic and stone with a grinder; a jigsaw is more suitable for wood, MDF and chipboard.

Step 2. Use a hammer drill to make grooves in the walls if necessary. The edges of the window sill will go into these recesses.

Step 3: Clean the installation surface from dust and debris.

Step 4. Into the groove window profile insert the window sill, having first removed it from the inserted edge protective film.

Step 5. Wooden wedges are placed under the window sill, starting from the outer ones and ending with the central ones. The substrates should not protrude beyond the walls and the inner edge of the window sill. The maximum distance between wedges should be 40 cm.

Step 6. Align the window sill with the spirit level. If there are deviations from the horizon, then correct with the help of additional wedges.

Note! The board should have a slope from the window to the inner edge of approximately 0.2 cm. This measure will prevent the accumulation of liquid near the window: the water will simply drain.

Step 7. Place a weight on the windowsill. Total load should be 10-20 kg.

Step 8. After we have additionally checked the horizontal position of the window sill board, we begin to secure it. For this purpose they use polyurethane foam. It is better to take professional foam and a special spray gun. Additional fixation to the window profile is carried out from the outside using self-tapping screws.

Note! When foam gets where it shouldn’t be, it is removed immediately with a cloth. If it has already hardened, you can wipe off the foam using special solvents.

Step 9. After 24 hours, remove the weight and trim off excess foam.

Now you can install the plugs at the ends and remove the protective film.

If you decide to install a wooden window sill, then on the inside of the board it is necessary to attach felt that has undergone antiseptic treatment using shingles. The ends of stone window sills are also protected with a felt layer before installation. Otherwise, the installation follows the same principle as for plastic products.

Thus, installing a window sill is not difficult, especially if we are talking about a plastic board. The main thing is to maintain precision in alignment when working and not to overdo it with polyurethane foam.
