Window sill extension. How to make a wide window sill

So, in order, the information is confirmed by the test reports of the leading manufacturers of polystyrene concrete, I made a conclusion for myself and wrote at the end of the commentary. MOISTURE RESISTANCE and HYGROSCOPICITY This is the most important property of any building material, especially in areas with high humidity. The higher the moisture resistance of the material, the more durable, stable and warmer it is. Polystyrene concrete absorbs no more than 6% of moisture from the atmosphere, it can be in the open air for almost unlimited time. STRENGTH Due to the super-strong cement-polystyrene matrix, polystyrene concrete has unique strength characteristics. This material is so durable that a fall from the height of a five-story building will not cause significant damage to the block. FIRE RESISTANCE Polystyrene concrete does not burn, it is able to withstand the enormous temperatures caused by fire, due to its unique thermal conductivity coefficient, it does not allow heat to penetrate deep into the wall. Flammability class NG. Fire resistance class EI180. DURABILITY The service life of a house made of polystyrene concrete is at least 100 years. Over the years, the strength of polystyrene concrete only increases. FROST RESISTANCE Tests for frost resistance and the amplitude of temperature fluctuations from + 75°С to - 30°С were carried out on 150 freeze-thaw cycles without loss of integrity and heat-insulating ability. THERMAL INSULATION It has long been recognized that polystyrene (styrofoam) is the best heat insulator in the world, it is even warmer than wood! A house made of polystyrene concrete does not require insulation: it is cool in summer and warm in winter. NOISE INSULATION Polystyrene concrete provides the best noise absorption rate, 18-20 cm dampens sound from 70 decibels. Consequently, there is special comfort in the house made of polystyrene concrete: noise from the street and inside from neighboring rooms and bathrooms does not disturb. ECONOMY The cost per square meter of a finished wall is cheaper than other materials. Due to the high level of heat retention, walls made of polystyrene concrete can be built 25% thinner than from alternative materials (aerated concrete and foam concrete) and 4 times thinner than brick. Savings on wall thickness lead to overall savings in the construction of the box (foundation, roof and walls) up to 50%. At the same time, the quality of the house will be even higher, and the house itself will be warmer. SEISMIC RESISTANCE Seismic resistance 9-12 points. Polystyrene concrete has not only compressive strength, but also the highest tensile and bending strength. Therefore, polystyrene concrete is considered the most reliable and earthquake-resistant material. LIGHTNESS A large-sized block 200x300x600 mm does not exceed the weight of 17 kg, which facilitates the work of a bricklayer and reduces the time for laying walls: it replaces 20 bricks in volume, and almost three times lighter in weight. ANTISEPTICITY The additive used in the manufacture of polystyrene concrete does not allow insects, rodents to start up in the walls, prevents the formation of mold and fungus that have a negative impact on health. VAPOR PERMEABILITY Polystyrene concrete walls “breathe” similarly to wood walls, and there is no danger from condensation and waterlogging for them. This provides a comfortable environment in houses made of polystyrene concrete. PLASTICITY Plasticity is the only material made of cellular concrete that makes it possible to produce window and door lintels, its bending strength is 50-60% of the compressive strength, for concrete this parameter is 9-11%. CRACK RESISTANCE Polystyrene concrete, due to its elasticity, is incredibly resistant to cracking. And this guarantees a long period of preservation of interior decoration and durability of the whole house. MANUFACTURING High speed of erection of wall structures due to the lightness and convenient geometry of the blocks. Easily sawn and chiseled, the ability to give the building material any geometric shape. ENVIRONMENTAL The International Building Code (IRC) classifies polystyrene as one of the most energy efficient and environmentally friendly insulation materials. Thus, polystyrene concrete has a lot of undeniable advantages over materials such as expanded clay concrete, autoclaved and non-autoclaved aerated concrete, foam concrete, wood concrete, etc. The disadvantages of polystyrene concrete appear only if its brand is chosen incorrectly and the masonry technology and preparation for interior decoration are violated. It can be said with absolute certainty that there is not a single significant advantage for materials such as aerated concrete and foam concrete over polystyrene concrete. At the same time, polystyrene concrete significantly surpasses them in key characteristics.

Very often in life there is a need to increase the window sill. The reason for the need to increase the window sill very often becomes an increase in the width of the bearing walls.

In order to save money, you can perform this action yourself.

How wide should the window sill be??

When installing a plastic window sill, it must be remembered that it should not interfere with the rise of warm air. That is why it is necessary to correctly calculate its width.

The permissible protrusion of the window sill should not exceed 50-70 millimeters. If the protrusion of the window sill is larger, then it will overlap the window sill, which will negatively affect air circulation.

Under the window itself, it is necessary to bring approximately 20 millimeters of the window sill. This fact must also be taken into account when calculating its length.

The width of the window sill directly depends on the width of the load-bearing wall. For example, if the width of the load-bearing wall is 50 centimeters, then it is necessary to add its plant under the window and ledge to the width of the window sill.

That is, with a bearing wall width of 50 centimeters, the width of the plastic window sill will be 57-59 centimeters.

Flowers are an original design solution for any room. Most often they are placed on the windowsills.

If the window sill is narrow and it is impossible to place flowers on it, then it is necessary to expand it. It is quite simple to do this, which allows the user to perform this action independently.

To expand the window sill, it is necessary to make a wooden beam, the width of which will be equal to 100 millimeters.

Four holes must be drilled in the front edge of the window sill, the diameter of which will be 12 millimeters. It is also necessary to drill appropriate holes in the beam at the same distance.

This requires pre-drilling 2mm holes. At the same time, the nail heads should be hidden under the window sill so as not to spoil the aesthetic appearance of the window.

In order to simplify the task of mounting the beam on metal rods, it is necessary to clean the holes from dust. For this purpose, a special brush is used.

In order to save space in the room, you can make a countertop from the windowsill. This countertop can be widely used in the kitchen, bedroom or office.

Initially, it is necessary to make measurements of the window sill, which will be used to make the countertop. In this case, the height of the countertop must fully correspond to the height of the window sill.

The far edge of the tabletop must be attached to the support profile, and the near one will rest against two specially made cabinets.

When installing the cabinet, it is imperative to align it vertically. It must completely coincide with the plane of the window sill. It is best to order cabinets for this, which will have adjustable legs.

After installing the cabinets, it is necessary to make a base for the countertop. For this purpose, you can use plywood, the thickness of which is at least 12 millimeters.

To protect the countertop from swelling, it is necessary to choose moisture-resistant plywood. The base for the future countertop is cut out in accordance with its configuration. For this purpose, a jigsaw.

The final step in installing the countertop is placing the plywood on the cabinets. Other materials can be used as countertops, but they will be much more difficult to process to the shape of the countertop.

At the same time, they are much stronger and more reliable than plywood.

How to enlarge the window sill? We have so little space in our apartments that it is a crime not to use a place that will be wasted in our conditions! Therefore, I decided to increase the window sill with my own hands!

The frame of the enlarged window sill was made in 1998 and has already passed

Continuing the review of our repair.

The first photo of an enlarged window sill with your own hands. Filmed on a phone, so the quality is not very good.

The quality of the photo, of course, leaves much to be desired, but this is the only and first photo of the enlarged window sill.

If you could turn left, you would see, which I also already wrote about

What we have? A small window sill, a small apartment, and a small kitchen!

Required: A large window sill, simply because the space is so small, and when it is not used, then those things that could be there take other places.

And the place above the battery is a dead place - there is just emptiness. So I decided to make such a window sill. I didn’t want to break the old window sill and start a major overhaul, so the decision came like this:

You need a piece of chipboard that will increase the window sill itself. So that it does not fall under any load, we put vertical racks, which will be the supporting structures for the elongated window sill.

We fasten a board 5 cm wide along the entire length of the concrete window sill. In order to attach a new window sill from above.

Vertical posts are fixed on the corners, holes are drilled in the concrete wall. And fixed to simple dowels 6 mm by 40 mm. Each post has 2 corners.

When you get a stable structure, the reliability of which you have no doubt, you need to combine a concrete window sill and its extension.

I took an ordinary fiberboard, and put a concrete window sill on top. Fill with titanium glue. We do not wish!

We drill carefully, because there are no reinforcements in the concrete window sills, so it can easily crack!

From the side of the chipboard, we nail the fiberboard with small carnations.

I made a rounding on the right, because I have a door there on

Well, there was a little space left to the right of the battery, I made two shelves, the width of the shelf turned out to be 17 cm.

I had leftovers from a roll of wood effect wallpaper that I bought for the balcony ceiling.

Cut out a strip for the end, leaving at least 1 cm to overlap. And glue the main piece on top.

I used ordinary wallpaper paste.

We varnish at least 3 times. It was nitro lacquer for me.

The second photo of the enlarged window sill with your own hands.

Since there is no photograph of the enlarged window sill in its original form in more or less decent quality, here is our photo before the next repair, around 2007 ...

Since I have a lot of materials, it is impossible to calculate the cost of manufacturing a window sill!

How much does it cost to enlarge a window sill?

Everything is made from leftovers. The only thing that was bought was white paint.

Total spent on materials:

A piece of chipboard - 0.00 rubles.

A piece of fiberboard - 0.00 rubles.

Glue Titanium - 0.00 rubles.

Wallpaper glue - 0.00 rubles

Lacquer - 0.00 rub.

Paint 1.0 liter - 150 rubles.

The amount of time spent on making a wide window sill.

Approximately 7 - 8 days.

Extended window sill version 1.1

And as they say in some films ... our days, well, or almost our days .. I already did this in 2010. The task was not to make a major overhaul, but only to build a marafet. That is a quick painting + skinned texture paper. Slightly sanded and needed to be trimmed a bit. And from above, I just decided to glue the facing film under the tree.

At the bottom of the shelves, I also decided not to paint, but to glue the facing film. In my opinion it worked out well.

Certainly! And here the quality of the photo is lame, then I didn’t have such

Moving to a new apartment, we were glad to increase our residential meters. But there is much less space for flowers. The window sills were so narrow that even a saucer could not hold on them, not to mention flower pots. The problem had to be solved urgently before we lost half of the collection. It was especially important to solve the problem of a narrow window sill in the kitchen.

Options

The first option that comes to mind is a plastic window with a plastic window sill. True, the window sill increases by only 10 centimeters. Not as big a gain as we would like. In addition, if the kitchen is small, the desktop (wherever it stands) makes the kitchen cramped and uncomfortable.

The decision came by itself. It is necessary to make a full-fledged work surface from the window sill - from wall to wall. In this case, the window sill will have a length of 2 m, a width of 45 cm (near the wall) and 60 cm (in the window opening).

Window sill installation

For the manufacture of a wide window sill, we used 2 simple narrow kitchen cabinets without a "top" and facades. These cabinets are easy to purchase at a home improvement store or ordered from a kitchen furniture company.

The bedside tables were placed sideways against the outer wall, opposite each other. Thus, they have become a reliable support for the countertop. Adjustable legs made it possible to adjust the height of the bedside tables and the level of the window sill.

For the countertop, we took a large sheet of plywood (12 mm). According to the plan, the tabletop is slightly wider than the bedside tables standing sideways, and goes into the window opening. Given the uneven geometry of the walls, the base for the countertop had to be cut out according to a pre-made pattern. For curly carving, an electric jigsaw was needed.

The next stage is facing the countertop with ceramic tiles. We used medium-sized tiles: with a small kitchen, large tiles visually reduce the free space, and laying very small tiles is a rather tedious task. As a result, the choice fell on the tile with which the wall was finished. The total size is 20x20 cm, while each one consists of four small "tiles" (10x10 cm).

To avoid wet processes, tiles were attached to plywood with glue, which is popularly called "liquid nails".

The seams were covered with white grout. The end was closed with an aluminum threshold. By the way, window slopes were made last, when the wide window sill was already completely ready.

Impressions from the operation of the window sill(after five years)

No need:

Making wide seams between tiles - the designer's desire to keep the size of the cells and lines, as on the wall, played a cruel joke. Rough seams 5 mm wide turned out to be "dirt accumulators". At first they were intensively cleaned and washed. However, from constant cleaning, the grout began to crack. Hence the moral: on the countertop (window sill), lay the tiles close, with minimal gaps.

Use embossed tiles, even if one has already been used for walls. From an aesthetic point of view, it is beautiful, but from a household one ... Embossed tiles have to be cleaned regularly with a brush (a rag is enough for a smooth surface).

In order not to block the gas valve, a large hatch (15x15 cm) is made in plywood, one whole tile serves as a cover for it. If necessary, the tiles are easy to remove. You can install a furniture handle on it. True, experience shows that even without a handle, such a hatch is quite convenient to use.

Today there is in every house and in every apartment. A modern window sill is a multifunctional device that, firstly, pleases the owners with the aesthetic appearance of the window, and secondly, plays the role of an additional place where you can store a variety of items. The second function is especially popular among modern consumers, because if you leave your car keys, wallet or any other important thing on the windowsill, you can easily find it there. However, most people, and especially housewives, use window sills as a breeding space. indoor plants and flowers. This process implies window sills considerable width, however, even the widest window sills may sometimes not be enough for a large number of flower pots. How to enlarge the window sill with your own hands, described below.

Extension wooden window sill

If the window sills in your home are made of wood, they can be expanded to the desired size using the materials at hand and our advice.

First you need to prepare a hardwood board. The board must be completely dry and free of cracks. If necessary, the board is adjusted to the desired size using a jigsaw or an ordinary saw. The edges of the board should be sanded and leveled.

Next, stock up on metal parts in the form of corners that will be used as brackets. The thickness of the board must match the thickness of the wooden window sill. The dimensions of the brackets should be selected in accordance with the parameters of the window sill, while taking into account that several screws or self-tapping screws will be screwed into the board. You should mark the place of the bend in advance and drill holes in the corners in the appropriate places. Of course, the joint of the bracket would be best welded together using a welding machine, but not every amateur craftsman has one with him. After the board and brackets are ready, you should firmly and securely fasten them. The bracket is screwed to the window sill and the wall, and the board, in turn, to the bracket. All parts of the new design must be perfectly matched to each other. Only in this case, the new window sill will be really reliable and able to withstand significant loads.

If you are not sure if the support that the bracket can provide is enough, you should modify the board. A special comb is cut out on its end side, and a corresponding groove is cut at the junction with the window sill. When assembling the structure, the comb is inserted into the groove, which makes it possible to give the window sill additional rigidity and strength. Also in this assembly option, you can use wood glue.

How enlarge stone window sill, concrete or plastic

If the extension wood window sill possible with only an additional board, then in the case of stone window sills, concrete or plastic It is not that simple.

Here the option with an additional element is not very suitable. If the width stone or plastic window sill It is not enough for you, it is recommended to simply replace it with a wider one. To do this, you need to remove the old window sill, prepare a place for installation and fix the new one.

Plastic slopes are easy to disassemble, after which it is easy to get access to pvc window sill. If the slopes are plastered, the window sill will have to be knocked out. Especially if it is made of stone or concrete.

Next, you should clean and prepare the place for installing the future window sill: remove the protruding parts, get rid of debris and prepare a new window sill. Do not forget about the accuracy and clarity in the markup. If at the time of installation it suddenly turns out that the new window sill does not quite fit, the work may be delayed. If the dimensions are exactly the same, you should install a new window sill in an empty place, and then fix it from below with wooden blocks. This option is well suited for plastic window sills. Any load is placed on top, after which all the free space under the window sill is filled with mounting foam.

In the case of window sills made of natural or artificial stone, as well as concrete, installation work becomes more complicated, since such window sills are of considerable weight. To install them, it is necessary to use a cement mortar, and in some cases, metal supports with a special fastening system.

It is worth remembering another small detail related to the expansion of window sills. Do not forget that after the above steps, the edge of the window sill will protrude much more forward from the side of the window. And therefore, the curtains and curtains hanging in the room will begin to touch him. To remedy this situation, it is necessary to replace the cornice or lengthen it so that the distance from the curtains to the wall becomes greater.
