Standard sizes of plastic windows for a private house

Standard sizes of plastic windows for a private house Standard sizes of plastic windows for a private house

According to regulatory documents, they are regulated dimensions of windows and other elements of the building structure. Yes, the numbers are not taken from the ceiling. In the case of windows, they will reflect the optimal characteristics in order to create a beautiful appearance of facades, normal lighting inside and minimize heat loss in winter.

SNiP and GOST requirements are mandatory for mass housing construction, but private builders often neglect the standard window sizes for a private house.

Standards and their rationale

Window openings play many functions.

Through them, sunlight will enter the premises, and even fresh clean, they make it possible not to feel locked in confined spaces, uniting it with the world outside the window. But at the same time, windows should provide good thermal insulation and be an excellent barrier to street noise, since otherwise the convenience of staying in the house will not be possible. The visual design of the structure and its visual perception also play an important role for her.

Please note that the facades of residential buildings look harmonious if the glazing area is from 40 to 50%.

The approved standards, the main of which has become GOST 11214-86, take into account such requirements and determine the ideal window sizes depending on the following factors:

  • The purpose of the room, as well as its purpose of application.

  • The area of ​​a particular room.
  • Dimensions of the building as a whole.
  • Climatic and geographical features of the placement of the house.
  • Wall material.
  • Technical parameters of fiberglass (glass thickness, materials of manufacture and number of glasses), on which the light transmission will depend.

By the way, standardization greatly facilitates the design of high-rise buildings, typical country cottages and townhouses, making it possible to do without additional calculations. At the same time, it allows certain deviations from the standards, giving a chance to make changes in different directions. For example, in the aforementioned GOST, the usual window height can vary from 1. 16 to 2.06 meters, and the width from 0.

87 to 2.67 meters. Private developers do not have to follow these rules. But for the sake of personal comfort, a positive emotional state and satisfaction, it is worth understanding how to correctly calculate the dimensions of window openings and place them relative to other structures.


Types of structures

Window area

Standard sizes of plastic windows for a private house To ensure that the room has normal lighting and does not require the use of artificial lighting in the house in the daytime, the glazing area should not be less than 0.

03 square meters per cubic meter of room volume. There are also more understandable, simple standards that require that the window area be no less than 6-8 times the area of ​​the illuminated room.

In other words, the ratio of areas in proportions should be in the range of 1 to 6 or 1 to 8. Or the window clearance should be from 13 to 16% of the main area. At the same time, the maximum proportions are used when the windows face the sunny side and do not obstruct other buildings or trees, and vice versa.

It is interesting that the larger the area of ​​the absolute glazing without bindings, the thicker the glass should be.

The specified values ​​are not used everywhere, but only in certain latitudes of geography. They are relevant within the range from 45 degrees north latitude, where cities such as Simferopol or Krasnodar are located, to 60 degrees north latitude, Vologda or St. Petersburg. In other regions, a decreasing or increasing factor is used.

Based on the size of the openings, windows in northern latitudes, according to different norms, should be larger than in southern ones, there is a problem of saving heat.

It will be solved by increasing the glass in the glass unit and the air chambers in the window profile. In areas with a subtropical climate, a single double-glazed window is quite enough, and in the North it is better to use a triple or double. It is important to clarify here that the two-chamber glass unit is made of 3 glasses and a pair of chambers with air, and the three-chamber glass unit is made of four glasses and three chambers.

Each glass makes light refraction more, which will negatively affect the penetration into the room.

For this reason, this parameter is also important to consider. Such norms make it possible to calculate the window opening for living rooms, but they are not necessary for sanitary facilities, verandas, terraces, storage rooms, where the windows can be much larger or smaller.

Placement of openings

The standard sizes of PVC windows for a private house are determined by standards, but of great importance for the comfort of people (psychologically) and the ergonomics of the use of space is also the placement of window openings on the wall. If we talk about the distance from the window sill to the floor, then it will differ for rooms with different purposes:

  • Attic - 1 meter.
  • Sanitary facilities - 1.

    3 meters.

  • Kitchen rooms - 0. 9 meters.
  • Living quarters - 0.8 meters.

But such a stepping has a terrible effect on the external facade view, and therefore the opening level on one floor needs to be leveled. An exception will be bathrooms, toilets, boiler rooms and other utility rooms, for which the ability to ventilate the room is more important than the degree of illumination. Due to the fact that the height of the window is extremely important for the facade aesthetics, then when calculating its ideal area, you can "play" with the width. But even here there are certain restrictions that relate to the indentation from the walls inside - the opening should not be located close to them. The minimum allowable indentation must be at least 1/2 meter.

Ideally, the window should be positioned perfectly in the center of the front wall.

The effect of the view of the window on the dimensions

When discussing the size of the window, the standard of lighting, do not forget that the opening in the opening will be partially blocked binders and frames. Their parameters differ depending on the design, strength, and the material from which they are made. Specialists who are engaged in the creation and installation of windows are well versed in what the width and thickness of the frame profile should be, the scheme of bindings for the opening of certain sizes, how many sashes can be made opening, and how many are deaf. It is worth listening to the recommendations and advice of professionals.

At the moment, the most popular are PVC windows or metal-plastic ones. They have many advantages over wooden ones:

  1. The dimensions of PVC windows, and also the area of ​​absolute glazing can be much larger due to the high strength of the metal-plastic profiles, which can bear a tangible load.
  2. They are quick to make and can be installed with ease.
  3. The configuration of plastic windows can be absolutely any, including with elements of the radius.
  4. The fittings are varied, and such windows are very functional, and the presence of air chambers in the profile is warm.

  5. Their price is lower than analogs made of wood with similar parameters.

But the bindings and frames in such structures are very powerful, they eat up a tangible part of the useful opening area. In this respect, windows with aluminum profiles are more effective, which allow an increase in the glazing area due to a smaller width with a comparable strength.

Arrangement of window openings

When creating openings in a house that has not yet been completed, it is necessary to take into account the wall material and manufacturing technology in order to maintain the size of the project.

In brick houses

In a house that is built of bricks, openings with a quarter are often made, equipping on the outside on the sides of they have small projections of 5-6 cm (this is 1/4 of a brick).

Such protrusions prevent the window structures from falling out to the outside, make cold bridges smaller and eliminate the need for finishing external slopes. As can be seen from the diagram, the inner opening is larger than the outer one, and therefore the window width should be sufficient for the frames to rest against the outer ledges on the sides. The abutment strip is 2-3 cm on each side, and 1.5-2 cm on top. The lower frame plane, on the contrary, should be raised 2 cm from the lower opening part, so that from the street side it is possible to equip ebb tides with a slope.

In houses made of wood

The standard sizes of windows in a private wooden house are convenient, because it is more convenient to fit openings for them. Due to the production of the flow method, such windows are cheaper than custom-made ones, but there may be complaints about their quality and functional part. But this is a good option for garden and country houses, outbuildings and baths.With openings in wooden houses, it is necessary to take into account the change in geometry as a result of house shrinkage and fluctuations in temperature and humidity. It is possible to avoid mechanical influence on the frames by means of a window, which is installed in the opening.

But its thickness must be taken into account when calculating the width and height of the opening.

In houses from blocks

When arranging a window opening in walls made of gas silicate or foam concrete blocks, it is necessary to take into account the dimensions and position in the masonry:

  • Side opening walls should not be placed in line with vertical joints.
  • The height of the opening will be limited from above by large rows of blocks, because a lintel is laid on them. It can be increased from below by cutting blocks.

If the facades are faced with bricks with quarters, they must be taken into account when calculating the dimensions of the openings.

In other cases, it is made 3-5 cm larger than the future window on each side, which are required for assembly seams.

Helpful hints

Windows are quite an important element in terms of functionality and aesthetics for every home. the quality of life will depend on the choice of their designs and sizes, as well as competent installation. For this reason, it is important to calculate, think over and weigh all the nuances in advance. For example, the windows with French technology, so beloved by many, are really chic - they create a feeling of space, let in the maximum amount of light into the room.

But their choice in the climate is associated with additional expenses for maintaining heat. During the initial installation of window frames or replacing old structures with new ones, it is required to correctly measure.

This is usually done by the installer, but home owners should be able to control them:

  • Standard sizes of plastic windows for a private house When measuring the width and height of the openings, measurements are performed at different parallel levels, and the least of the data obtained is taken into account.
  • The height of the windows for the attic is selected taking into account the degree of the roof slope. They are placed between the rafters in such a way that at least 6 cm is left from both sides of them to the window box.

  • When installing, it is imperative to use a building level for mounting frames in an ideally vertical position.

The dimensions of windows for a country house are solely a matter of taste and preferences. But it is better to choose it, focusing on the standards and norms that are developed taking into account climate conditions, lighting standards, safety rules and other rather important factors that affect the convenience of living.
