Wide window sill: alternative installation. Plastic window sills (PVC window sill) How to make a large window sill in a panel house

A window sill in the traditional sense is boring and unflattering. Its narrow surface, at best, is perceived as a stand for house plants, at worst - as an annoying misunderstanding that hides precious “squares”. And rarely does anyone think that by increasing its size, you can make a window sill a multifunctional item for improving your home space.

In the West, they have long learned to transform ordinary window sills into sofas, tables and other interior elements. You just need to use your imagination, and the boring continuation of the window from a useless piece of plastic turns into a cozy corner for tea drinking - when the window sill expands and becomes a table, or into a compact library - when it continues bookshelves, or a stylish podium, or... We will talk about these very “or” in this article.

From the living space of tiny, small-sized apartments, in which literally every centimeter is precious, it is so pathetic and painful to throw out an entire wall dedicated to a window. Meanwhile, it is quite possible to make this space useful and functional. Narrow partitions can be equipped with bookshelves, and the window sill itself can be turned into a cozy philosophical corner.

A window sill belonging to a panoramic window may well become the main space-forming element of the interior design. In this option, it is he who will act as a trendsetter of fashion and style in the premises under his control.

A standard plastic extension of the window would look wild and incomprehensible here, like an aborigine in a loincloth under a snow-covered tree. The forms flow from one to another so naturally that they form a single whole, competent and complete.

Unfortunately, not everyone has a country house where it is so pleasant and joyful to spend weekends. So why not create at least the illusion of warmth and color outside the window?

IN Lately, it is the plastic options that are incredibly popular. First of all, their practicality, durability and ease of installation are taken into account.

They perform not only a practical role, but also an important aesthetic function: they decorate the room and make it more complete. decoratively. The interior space of the room looks organic and complete.

There are both standard models with certain dimensions, and plastic sheets that allow you to model a window sill according to your own sketch. A wide range of colors realizes any design solutions. Using plastic, imitations of the structure of wood, stone, and granite are created. Outwardly it looks attractive and very unusual.

Measurements and calculations

To measure right size window sill board, it is necessary to take into account the recesses that remained after dismantling the old structure. As a rule, the length of a new plastic window sill is 50-150 mm longer than the old one.

The width, in turn, is 30-40 mm, since, unlike a plastic frame of 60-70 mm, wooden frames are 100 m thick. The overhang of the window sill should be at least 10 mm, but not overlap the heating devices.

Standard parameters of window sills:

1. Length standard plastic panels – 4500-6000 mm. As a rule, six-meter strips are supplied to stores and markets, which are cut to the required size on site.
2. Width– 100-1000 mm in increments of 50 mm, which allows the use of plastic window sills with different thicknesses of wall partitions. Thanks to this property, the installation depth and further operational characteristics vary.
3. Thickness– 18-22 mm, on which the strength of the product depends, the functional loads and service life are determined.

Subtleties of choice

Very important nuance is the quality of the product. Despite the fact that plastic window sill boards may look the same, however, in terms of their content and conscientious execution, they are completely different. How to distinguish a good manufacturer from an outright hack?

All types are divided into premium, middle and economy classes:

Economy options

These include window sill blocks made in Russia and China. They have low cost, small assortment of colors, smaller guarantee period and are lighter compared to their German counterparts.

Such manufacturers include window sill blocks NikoPlast, Montblanc, Bauset. This does not mean that the window sills of these companies are not suitable for use. Not at all. They are simply not designed for heavy loads; they have thinner ribs and an imperfect surface.

There are cases when thin PVC boards develop characteristic black spots over time that cannot be removed.

Middle class

Characterized by reinforced ribs and increased strength properties. Covered with protective polymer film and have enough wide choose colors. Produced in Belgium, Ukraine and Russia. These include companies Vitrage, FineDek. The sizes are selected individually, and the window sill board itself has high wear resistance.

Premium class

An ideal option, the service life of which can reach 70 years. The peculiarity of one of the elite German designs is the monolithic fusion of crushed wood and polymer resins.

The company Werzalit uses a similar production method. Such window sills are heavier than standard ones, but are durable and have high strength. Premium manufacturers cover window sill blocks with acrylic protective film, which makes them resistant to thermal and mechanical influences.

The following companies are noted: Moeller, Danke, Melenger and Crystalit.

Application area

The main feature of a plastic window sill– possibility of use in residential premises, offices, hotel complexes, educational, medical and some industrial institutions. Such a wide range of distribution is explained by high performance characteristics, beautiful color scheme and excellent strength properties.

Depending on the size, there are two types of window sill blocks that are used in apartments:

1. For panel structures use window sills 200-300 mm wide.
2. For brick– 500-600 mm wide.

A more unique area of ​​application are plastic bar counters and tabletops.

3. With imitation marble, granite and stone coating.
4. Bright creative colors.

They also differ depending on the type of coating:

1. Using melamine as surface, you can achieve high temperature characteristics, moisture resistance and any shape. The technology consists of applying 7 various types coatings based on polymer resins.
2. The second more popular type is PVC film, which has low cost, is resistant to open fire and ultraviolet radiation.
3. Acrylic coating – an achievement of modern industry, which allows the implementation of the most sophisticated color solutions. Acrylic film can withstand mechanical loads, serious temperature changes, does not scratch, and always remains smooth and uniform.

Main characteristics:

1. Racks for loads from 5 to 10 kg per square meter.
2. Have a wide temperature Range – 30-60 degrees.
3. Weight from 7 kg per 1 square meter.
4. Various stiffeners: diagonal and vertical, on which the strength of the window sill blocks depends.

Advantages and disadvantages

When choosing one or another type of window sill design, the buyer relies on advantages that will help him cope with various purposes.

It is very important to know what advantages plastic window sills have:

1. Appearance of window sill slabs. They look beautiful, fit into any interior and have a classic feel. white look, and other color options.
2. High strength qualities. Achieved through stiffening ribs, increased thickness of the surface fabric and solidity of the structure.

Do you want to carve out at least a little usable space on your small kitchen? This is possible if you use the window sill - replace it with a tabletop and integrate it into the work or dining area. From this article you will learn how to do this as efficiently as possible, what technical nuances need to be taken into account when remodeling and what variations of the window sill-countertop there are.

General rules for remodeling a window sill-table top and practical tips

1. The main condition for arranging a window sill-tabletop of any configuration is that air must circulate freely around the radiator.

The heat from the battery should rise unhindered to the window, and cold air from the window - go down. Otherwise, the kitchen will become cold and damp and, what is even more dangerous, the kitchen windows will begin to constantly fog up. If the latter happens, then the window slopes, and then the kitchen walls, will become covered with mold.

What to do? If you plan to use the tabletop-window sill as a table or cabinet with open shelves, then for normal air exchange it is enough to make several holes in it or build in a ventilation grille as shown in these photo examples.

If you plan to equip the underframe of the window sill-countertop with cabinets, then their doors should have perforations or lattice inserts, as, for example, in this photo.

An example of arranging a cabinet with lattice doors under a window sill-countertop

1. Keep in mind that a window sill-countertop and, especially, a cabinet built above the radiator (even with lattice doors) will worsen the heating of the kitchen (by 2-3 degrees). Heat loss can be compensated by installing an additional radiator or underfloor heating systems. In addition, the battery from under the window sill can be moved to another location along the same wall or to an adjacent wall. Relocating a radiator ideally requires a coordinated design and thermal calculation, however, in practice agreement is often sufficient Management company Houses. And one more nuance - since moving/replacing the battery requires turning off the riser and draining the water, this should be done during the non-heating season.
2. The window must be at least 1.5 cm higher than the window sill-table top.
3. To avoid the formation of mold on window slopes, do not forget to treat them with an antiseptic primer. And so that the slopes can be frequently cleaned from accidental stains and splashes, they should be painted with moisture-resistant paint.
4. Under no circumstances should you install a stove on a windowsill-tabletop. Firstly, this is prohibited by sanitary and building codes, and secondly, it is simply impractical, because splashes of oil during cooking will certainly end up on the windows.
5. When planning to leave the battery under the windowsill-countertop in plain sight, it is highly advisable cover it with a decorative screen, paint in bright color or to match the wall. However, sometimes it is enough to replace a large and outdated radiator with a more compact and modern one.

Radiator with perforated screen under the window sill-table top

1. Due to the proximity of the window and adjoining external wall The window sill-tabletop must be made of super-wear-resistant material. Perfect option – fake diamond, which is not afraid of either moisture or culinary work and, moreover, allows you to create a seamless surface. If outer wall If the kitchen freezes and leaks, the windows are prone to fogging, and mold once “bloomed” in the room, then you should play it safe and choose artificial stone for arranging the window sill-countertop.

1. No matter how you arrange the space under the window, it should be well lit. For this you can use wall sconces or pendant lamps. If the window sill-tabletop serves as a bar counter, then hanging lamp can be hung at a height of 70 cm from its surface. Lamps above work area they can hang higher, the main thing is to place them directly above or in front of the workplace, and not behind it (otherwise the person standing behind the tabletop will simply block the light from the lamp with his back).

1. It is most practical to decorate the window above the window sill-tabletop with cassette roller blinds, attached directly to the sash. Also, all types of short curtains are suitable for window decoration: Roman curtains, standard “rolls”, horizontal blinds, cafe curtains or classic curtains.

1. Sometimes, to get the most out of a kitchenette, you need a window sill-countertop with an irregularly shaped canopy. So, for example, it can narrow in an area of ​​high traffic (say, near the refrigerator) and expand where there is more space.

It is also very good when the corners of the window sill tabletop are not sharp, but rounded.

1. When arranging a working window sill-table top it can become a problem search for built-in dishwasher suitable height, because Most PMM models are designed for a height of the lower tier of the kitchen of 82 cm.
2. If the window sill has very wide slopes, then it is advisable to make its new countertop (and the cabinets and possibly the sink that go with it) narrower. After all, if you add up the depth of a wide window sill with the depth of a standard 60-centimeter tabletop, it turns out too long distance from the window to the edge of the table.

Options for arranging a window sill-countertop

The window sill-tabletop can be equipped and used as:

• Work area with sink under the window;
• A work surface for preparing food (without washing);
• Dining area or bar counter for breakfasts and snacks;
• Additional storage space for equipment, food and utensils.

Let's look at each of these options in more detail.

Window sill-tabletop as a work surface (without sink)

Converting a window sill into a countertop allows you to increase the working surface with minimal clutter in the kitchen, making it possible to cook under a pleasant daylight and with a view out the window. Also, the window sill-tabletop offers a bonus - the ability to use it as a bar table or equip the underframe with additional storage space. However, at the window sill work surface there are also disadvantages:

Since most often a window sill-countertop involves combining it with a suite, the question arises - what to do if the height of the window sill and the kitchen floor cabinets do not match? Here are some solutions:

• If the window sill is higher than the cabinets, the headset, then everything is simple: kitchen countertop and cabinets line up under the window. In this case, the gap between the window sill and the tabletop is protected with the same material that is used to decorate the apron or is covered with a ventilation grille. In this case, the canopy of the window sill table top can be cut off, the window sill can be replaced with a panel to match the table top and used as a shelf.

• If the difference between the window sill and the cabinets is small, then the kitchen furniture is adjusted to the window sill due to the base and legs, less often due to the height of the cabinets themselves and increasing the height of the floor. Here are some useful numbers:

• The standard height of the cabinets (without table top and base) is 72 cm.
• The base has two sizes - 10 cm and 15 cm.
• The height of the kitchen window sill in a city apartment can vary from 72 to 90 cm (excluding the countertop).
• The standard thickness of a kitchen worktop (it must be taken into account when calculating the final height of the kitchen) is 4 cm or 2.5 cm (less often).
• Ideally, the height of the working surface should be 15 cm lower than the bent elbow of the owner/hostess of the kitchen.

• If the window sill is lower kitchen furniture , then converting it into a countertop is more difficult. The most radical method is the following: the window sill is increased to match the height of the furniture, and the window is installed smaller. However, this is only possible in a private house, and in a city apartment such interference load-bearing wall and the front of the building is prohibited. However, if the window faces the loggia, then it is theoretically possible to “raise” it legally. The second method: the size of the window opening does not change, but the design of the window changes - it is supplemented with a horizontal impost (an additional frame profile). As a result Bottom part it turns out to be blank and is closed by a cabinet, while the shutters above the window sill open as usual. From the outside, the blind part of the window can be hidden behind a balcony flower “pot”.

This window sill tabletop could look even better if the window mullion ran directly above the table

The third and easiest way: the kitchen is simply installed on top of the window sill (see photo below), and the niche formed behind it is used for storing household chemicals or indoor plants. Unfortunately, this solution is not ideal: you will no longer be able to open the window wide open, the niche will not be so easy to tidy up, the insolation of the room will worsen, and from the point of view of fire safety the idea is not very successful. However, these inconveniences are not so critical.

And finally, the fourth method: the window sill and furniture are combined, but are not adjusted to each other in height, but the kitchen countertop is adjusted to them. You can beat the difference between surfaces different ways. For example, different levels of the kitchen can simply be lined with the same countertops. As a result, the interior will turn out, although not so harmonious, but overall it will look good.

Also, different levels of the kitchen can be united by a single tabletop with invisible seams (in this case it should be made of wood, or better yet, artificial stone of a contrasting color).

Window sill-tabletop with sink

A window sill-countertop with a sink is the most desirable, complex and costly remodeling project to implement. Indeed, in addition to the problems described in the previous chapter, there is also the issue of connecting water supply and drainage pipes to the window. In addition, washing in the windowsill, although it brightens up the home routine with pleasant lighting and a view of the surrounding area, in practice it is not always convenient. Firstly, if window slopes not too wide, the window will often get splashed. Secondly, the sink faucet will prevent the windows from opening.

How to move the sink to the window and connect water communications to it?

With pipe supply for hot and cold water As a rule, no problems arise, but you will have to worry about connecting the drain pipe from the sink to the riser - install it at an angle of 2-3 cm for each meter of length. In this case, all communications need to be hidden, for example, inside kitchen set, V plasterboard box go to the podium.

Now a little about coordinating the transfer of the sink. If you are moving the sink along the “native” wall, then developing a project is not required. Moving the sink to the opposite or adjacent walls already requires the development of a project and its legalization in housing authorities.

Here are other useful tips for arranging a window sill-countertop with a sink:

• It is advisable that at least one casement opened 90 degrees, then you can wash the window completely without any problems. To do this, you need to place the sink not in the center of the opening, but closer to the edge.

The exception is three-leaf windows - in this case the sink is placed opposite the central blind sash.

• To window glass avoid splashes of water as little as possible, choose a deep sink, and it is better to choose a faucet with a medium or deep spout.
• If possible, it is worth installing a folding faucet (with a bayonet mount) instead of a conventional faucet. Such models are more expensive, but they allow you to open the windowsill-tabletop windows wide open without any problems.
• Since there cannot be a cabinet for storing dishes above the sink near the window, it should be provided on the side of the sink or under it. For the same reason, you should choose a sink with a wing for drying dishes.

Window sill-tabletop as a dining area or snack area

Convert a window sill into a bar counter or dinner table The easiest way is to just replace the tabletop, add one or two supports or a table (if necessary) and select suitable chairs. As a result, the dining area turns out to be compact, well-lit and very cozy.

• Keep in mind that there must be a distance of at least 25 cm from the front edge of the window sill-bar counter to the radiator/wall, otherwise the feet of those sitting will rest against them.

• The shape of the window sill table can be irregular shape as shown in the photo below.

C-shaped kitchen with window sill-bar counter

• How to make a dining table-window sill with your own hands? Just install a folding wall table at the same level as in the photo below.

The balcony has long ceased to exist utility room and container unnecessary trash. Today it's stylish extra room or a landscaped space for a recreation area, workshop, or office. Glazing and insulation are the basis of a future comfortable balcony or loggia. Plastic windows and balcony glazing frames look complete thanks to installed window sills. We will talk about choosing and installing a window sill.

Plastic window sills

PVC products are perfectly combined and matched when installed with any window profiles made of metal-plastic. Their popularity depends on the following properties and performance characteristics:

• The ability to laminate with durable decorative film of various colors and textures, which retains its presentable appearance for decades, and minor mechanical impacts do not leave scratches or chips on it.
• The material does not rot, does not fade in the sun, is resistant to temperature changes, low temperatures and high humidity.
• Plastic window sills are easy to maintain, do not require periodic painting and are durable under normal operating conditions.
• Internal stiffening ribs provide a fairly light product with high strength.
• Dividing the internal volume into cavities increases thermal insulation properties window sill.
• The material of the product does not support combustion and is highly flammable.
• Dismantling and installation is carried out without special tools.
• Environmental friendliness.

When choosing a window sill made of plastic, you need to remember that it is impossible to repair it once a dent or hole has been punched on the surface. The issue is resolved by completely replacing the product.

Wooden window sills

Wood products always look natural, stylish and cozy. The type of wood and the degree of drying are the main indicators that influence the quality of the resulting window sill. Hardwood - oak, beech, larch and others - is used to create a solid window sill. Its luxurious texture will be emphasized special wax, and oils and impregnations will protect against moisture, microorganisms, and the possibility of fire.

The technology for producing finger-joined laminated panels from bars (lamellas) of cheaper species allows products to be made cheaper. Window sills are made this way various forms and sizes. Their strength is almost twice that of solid ones. wooden products from the same breed.

Flaws wooden window sills – the possibility of swelling, cracking, exposure to temperature changes, fear of direct sunlight, fading of coatings in the sun, the need for careful constant care.

Window sills made of chipboard and MDF

The material of the products is wood chips, which are compressed and covered with a reliable layer of laminate. Window sills of this type can be classified as wooden products, but they differ significantly in the following characteristics:

• more rigid and durable;
• retain their shape and original dimensions under the influence of external factors;
• resistant to heat and moisture;
• wide selection of texture and color options;
• ease of maintenance (it is advisable to exclude the use of abrasive cleaning products);
• lower cost.

Marble and granite window sills

These are the most common breeds natural stone, used for the manufacture of window sills. They always look rich, solid, textured. The main advantages of stone products:

• durability while maintaining a beautiful original appearance;
• homogeneity of the material;
• environmental friendliness;
• increased strength;
• organic compatibility with various finishing materials;
• resistance to peak temperatures and sudden changes;
• hygiene;
• variety of textures of different colors and shades;
• practicality in care.

Of the minuses, we note the following:

• Heavy weight, which limits its use on external balconies and balconies with lightweight parapets.
• High price.

Window sills made of artificial stone

The basis of the material is mineral fillers, bound into a monolith with polymer resins and tinted with dye in the desired shade. Fake diamond cheaper, but looks rich, just like natural. Window sills made from it are durable, not afraid of impact loads, resistant to chemical influences. A small minus is poor resistance to abrasive cleaning. It is recommended to use special polishes for them.

Marking, trimming window sill blanks

Selecting material, color or option decorative finishing of the future window sill, we begin the main work. At the first stage, the workpiece for the window sill is marked and trimmed. Its length corresponds to the length of the installed frame. For a linear window sill along window frame The workpiece should be cut according to the markings with a perpendicular cut. If the future structure will go around the perimeter of the front and sides of the parapet along a broken line, more careful marking of the window sill will be required, taking into account the angles at which the sections of blanks connected into a single whole will be located to each other.

To determine the width, measure the distance from the glazing frame to the inner edge of the opening (for a loggia) or parapet. If you plan to place shelves or cabinets under the window sill, measure the distance to the edge of the frame (for shelves) or the edge of the hinged door (for cabinets). To the obtained value add 2-3 cm, by which the window sill will be placed under the frame during installation, and 5-8 cm - the amount of the outlet (canopy). The size of the canopy is selected taking into account saving balcony space. A large window sill outlet will prevent the proper circulation of warm air, which prevents condensation from forming on the double-glazed windows. The required thickness of the window sill is selected at the stage of purchasing the production blank.

You can trim a wooden and PVC window sill with a jigsaw, a saw with a fine tooth, or a grinder (for wood you need a special cutting wheel). When working, control the speed of the tool and the force applied to it to obtain smooth edges without scratches, cracks or chips.

Window sill installation

You need to prepare for the installation of the window sill. To install a PVC product, it will be useful to screw it under the bottom of the frame U-shaped profile made of plastic. The longitudinal end of the trimmed window sill blank will be inserted into it.

The profile location is set strictly horizontal, without sagging (depending on the distance between the fasteners). To give rigidity to a long window sill, use a backing made of wooden blocks. They are laid 25-30 cm apart on a parapet or frame under the window sill and secured with screws or cement mortar. The length of the bars should not reach the edge of the opening or frame 1-2 cm.

Under a window sill with a large projection, or which will be subject to significant static loads during operation, you need to install several support brackets. They will take on a significant part of the total load.

After the preparation has been completed, the window sill is installed.

Important! Before placing the PVC window sill board under the window, special decorative plugs are attached to its ends.

The panel is carefully inserted into a pre-fixed U-shaped profile or placed under the frame and secured. Knock the window sill to the junction with the frame with gentle blows through the extension so as not to damage the surface of the material. Installation of the board is carried out while maintaining an inclination (no more than 3-4 degrees) towards the room to prevent the accumulation of possible condensation. At this stage, we obtain a window sill installed and lying on supports made of wooden blocks.

Now we need to do the low tide. When its installation is completed, fill out polyurethane foam gaps and cracks between the window sill and the parapet (if it is concrete or brick), or a frame intended for shelves, cabinets, and insulation devices.

Before this, the installed part is securely fastened and expanded so that the pressure of the foam cannot lift or deform it.

Narrow balcony window sills are fastened by installing them on a construction or special adhesive mortar. With this method, specially installed spacers act as a press.

It is advisable to entrust the installation of stone window sills to specialists from a specialized company. Without experience in such work, any miscalculation can be very expensive.

The video shows two methods for installing a window sill:

Nuances of choosing and installing window sills

1. Matte and rough plastic is better than glossy plastic, suitable for use on the balcony. It hides the ubiquitous dust and minor scratches on its surface.
2. A wooden window sill requires proper protection from dampness; it is better to install it on an insulated balcony.
3. For massive window sills made of artificial or natural stone, you will need a reliable parapet base - concrete, brick. Such products are more suitable for use on loggias.
4. Due to the big total length balcony frame, supporting brackets are required for the window sill. A wooden or metal (profile) frame for insulation can cope with their role.
5. The choice of the width and material of the future window sill should also take into account its additional functional purpose and expected loads - use as a shelf or tabletop.
