Large round windows – maximum illumination of the house

Not a single home can exist without windows - this way of life has already lasted for many thousands of years. However, today the function of a window is not limited to letting light into the room. Currently, light-transmitting design plays a huge role in organizing a certain style solution indoors and complements it. The size, shape of the window, and color determine how well it will fit into the overall interior of the room.

Non-standard windows, such as round ones, look original and stylish. Country houses, dachas, cottages will especially benefit from their installation - since their architecture often involves the use of intricate solutions that allow round windows to be organically incorporated, both in contact with the external environment (with the street) and located inside the building, dividing rooms, for example , bathroom and kitchen, office and bedroom.

In most cases, the owners of such houses resort to installing structures based on plastic in the window opening, because they are cheaper than wooden ones, although they are not without some drawbacks (we will consider them at the end of the article), and in terms of color they can be identical to natural material, and with maintaining its structure.

Types of round windows

Plastic products for this purpose are divided into several types, each of which is determined by the method of opening the sash and, accordingly, by a different level of functionality of the light-transmitting structure as a whole.

Non-opening (fixed) windows

The absence of imposts (frames dividing the window into parts) has a positive effect on the level of illumination of a glazed room - this type of window lets in more light compared to structures that have one or more imposts.

Also, blind models are distinguished by their low price, which is formed mainly due to the presence of a single, but significant drawback: windows of this type, in principle, cannot be opened, which imposes some restrictions, for example, when ventilating. However, this minus turns into a plus when windows are located indoors, on the walls dividing rooms, or in inter-corridor partitions - with such windows, as mentioned above, the interior space is better illuminated.

Windows with opening sashes

Depending on the preferences of the owners, such windows can have either one or two opening sashes, and they can be located either vertically or horizontally. Compared to blind structures, due to the presence of an impost, such structures allow less light to pass through, but allow for complete ventilation of the room: either by opening the doors or using the so-called micro-ventilation function.

Mid-hung structures

Middle-hung is the most popular system for opening round windows. It implies the ability to open window sashes, both vertically and horizontally - the structures are equipped with special components that slow down the closing of the sashes. Thus, opening round windows have a wide range of functionality - they are easy to clean and safe to use.

Bottom hung systems

They differ from mid-hung ones in that the window sash opens inward, rotating around the lower axis.

Options for opening round windows:

The minimum diameter of round windows is 700 mm

Maximum diameter of a plastic window 2000 mm

Blind (non-opening) window. If you decide to choose a model without active sashes, you must take into account that blind structures can only be washed from the reverse side.

Window with an opening sash. Such windows allow you to ventilate rooms and, thanks to the additional lintel, have increased rigidity. However, during operation it is not always convenient to lower or raise the active sash. Also, with a large structure, it may be difficult to access the entire outer part of the glass unit when washing windows.

Semi-circular hinged door system. This round window functions almost the same as a regular rectangular model. The number of active sashes is determined by the customer. It is possible to integrate rectangular vents into a round structure. It should be taken into account that a large number of vertical or horizontal imposts reduces the light transmittance of windows. If there is an insufficient number of active sashes and their small sizes, access to the outer part of the double-glazed windows is difficult.

Mid-hung round window.
The sash is located inside the structure and can open in any direction, even at an angle. A convenient model that allows you to easily ventilate the premises and wash the double-glazed windows. Thanks to the improved fittings, even large doors move easily when opened. Such models provide ideal air circulation when ventilating rooms. Related articles:

Pros and cons of using

If you want to create practical, unusual round window openings for home decoration, then it is important to know the main features and advantages of this option. So, the positive aspects include the following factors:

Originality. Regardless of the material chosen for finishing the walls outside, round windows will look unusual and original. It is very important that the building is designed in strict geometric shapes. In this case, you can create harmony in the building;

Visual “smoothing” of strict forms. If the building has strict geometric shapes and looks too conservative, then the use of the presented facade elements is what you need. The house will look more neat, while it is possible to create a cozy atmosphere on the site and inside the house;

It is worth noting that the appearance of the house is a full-fledged part of the landscape design. This must be taken into account when decorating external walls. It is round openings that will help emphasize any landscape design, giving it lightness and tranquility.

But there are also important disadvantages that must be taken into account.

The main disadvantage of using such elements is the limited number of options. Today, profiles of this shape are produced in limited quantities in size and diameter. Such windows cannot be large, which can negatively affect the appearance of a private home. At the same time, exposure to sunlight will also be minimal, which can create unpleasant living conditions indoors.

Decoration of the window space

Windows will look much better if you carefully think through all the design details - external and internal, and draw up a plan for the location of structures and elements that will complement the window. Platbands play an important role, giving it a finished look.

To frame the window from the outside, materials that are resistant to various weather conditions are chosen, and the top is covered with a special protective compound. Platbands are chosen taking into account the material and the general style of knowledge. For brick houses, plastic is more suitable; in a wooden house, it would be more logical to make platbands from wood, which you must remember to periodically care for by covering it with a special primer. Platbands can have decorative elements in the form of carvings and figured inserts.

Plastic trims are easier to maintain; they just need to be wiped clean from dust.

Material for making round windows

Currently, PVC or aluminum profiles, as well as natural wood, are used to make round frames and sashes.
Radial shapes are given to these structures in different ways, and their characteristics have some differences. In order not to make a mistake when choosing, you need to know the basic properties of each of the listed materials. Articles on the topic:

Round aluminum windows

Depending on energy efficiency requirements, a round aluminum window can be made from either a cold or warm profile. This allows you to avoid overpaying when products are ordered for installation in unheated rooms. Unlike cold windows, which consist entirely of aluminum, warm windows are made from profile systems that have an additional liner made of polymer material. This element has low thermal conductivity, thanks to which it helps to maintain a comfortable indoor temperature at no extra cost.

Cold and warm windows are made using profile bending equipment, which allows metal blanks to be given the desired shape. This technology is based on the fact that aluminum profiles are passed through a system of rollers. Under the influence of a uniformly distributed external force, after a certain number of cycles, the moldings become curved.

Due to the properties of aluminum, round windows made of this material have the following advantages:

pros

long service life - from 80 to 100 years

high rigidity and resistance to deformation

ability to withstand external mechanical influence well

The price factor is considered a conditional disadvantage - a round aluminum window sometimes costs 2 times more than plastic products.
However, this is fully compensated by the strength and durability of metal structures. Related articles:

Why are rotating double-glazed windows better than classic ones?

A mid-hung window that rotates 180 degrees on its axis opens up new possibilities for use and makes it easy to maintain.

The room is ventilated much faster. A slightly open window creates 2 air flows according to physical laws - warm air leaves from above, while fresh cool air enters from below. In a children's room, such a window will allow you to completely ventilate the room in 15 minutes while you have lunch or take a walk.

Easier and easier to clean. Now you don’t need to remove flower pots and reach the most inaccessible places from the outside - just turn the sash and wipe the entire window in 5 minutes.

Ergonomics of space. You cannot place a tall flowerpot or furniture next to a casement window - you need space to open the sash.

The rotating design solves this problem, which is especially important for small apartments, where every centimeter counts.

Unique design. Along with all the operational benefits, you get an original interior element. It will make your home space more modern and attractive.

Wooden windows all around

A round window in a wooden house or an expensive brick cottage looks more solid than its plastic or aluminum counterparts, which is why property owners prefer to order just such models. Theoretically, these products can be made in 2 ways - by bending a solid beam and by splicing individual small beams (plots). However, in reality, almost all manufacturers use only the second option, since the first method is very long and expensive. In addition, a bent profile made from solid timber has a high tendency to deformation, which is unacceptable for windows.

Frames and sashes made from spliced ​​solid wood hold their shape well. Modern technologies for joining, sanding and finishing make it possible to disguise the joints well, so round wooden windows look like a solid structure.

The advantages of such models are well known:

pros

Environmental friendliness

Service life up to 100 years

Excellent thermal insulation and sound absorption levels

The disadvantage of wooden windows is that the outer covering will sooner or later have to be renewed.
The service life of factory-made paint on the outside depends on the class of products. For economy class windows they are 5-8 years, for premium category models - from 25 years. It should also be taken into account that if the manufacturer violates wood processing technologies, the products may change shape during operation. Related articles:

Curtains

Protection from excess street light and prying eyes, in the case of round windows, requires a slightly different approach than when designing conventional rectangular structures. In some cases, you can do without curtains, for example, when it comes to opaque glazing or when installing stained glass models.

Common types of curtains for decorating round windows:

• Pleated blinds. Affordable and easy to install option. In addition, in the modern market it is not difficult to find a suitable color and texture. To purchase a kit that matches the frame specifications, you will need a frame template. It’s not difficult to do it yourself, but it’s better to turn to specialists - order blinds and installation. Pleated fabrics are perfect for both round and semicircular designs. Therefore, if it is necessary to decorate the top of an arched window, such blinds can be considered.

• Regular blinds. A type of design that is more complex to manufacture and install. The rounded shape of the frame and non-standard mounting hardware significantly increase the cost. However, the result is durable and practical. Traditional blinds are easy to use, functional and allow you to control the amount of ambient light.

• Straight curtains. The least common option for round windows, and so that it does not spoil the overall appearance, it is better to approach the issue creatively. For example, choose unusual, beautiful fittings, use an alternative method of fixing it to the cornice, or buy an arched cornice.

For rooms decorated in a classic style, lambrequins are suitable.

This solution is quite simple to implement, and you probably won’t need to call a specialist. In addition, with the help of a lambrequin it is easy to design any diameter, which allows it to be used even for large openings.

Round plastic windows

These models are the most popular due to their good performance and ease of use. Round plastic windows are made using thermal bending technology. In a special chamber, the profiles are heated and then, using pre-prepared templates, they are given the desired shape on a table with a perfectly smooth surface. Frozen plastic does not straighten and retains its previous properties.

Round window sizes

Due to the peculiarities of manufacturing and operation, the dimensions of round windows differ from the dimensions of rectangular windows. This parameter is also influenced by the material of manufacture.

Maximum and minimum size of casement windows (mm)

Maximum and minimum size of windows with fixed sashes (mm)

Since manufacturers work with different types of profiles and types of wood, the maximum and minimum diameters of round windows may differ.

Expert commentary

Vladislav Dobronravov

Leading technical specialist at Okna-Media company

Due to the existence of restrictions on the size of these products, a round window in a brick wall or concrete plane must be designed during the construction phase of the building.
After all, adapting the size of the opening will be too difficult or completely impossible. Related articles:

Requirements

The main design parameters are regulated by regulatory documents. Round-shaped products must comply with the following documents :

1. GOST 30673-99. The text describes the main parameters that confirm the quality of the profile.
2. GOST 24866-99. The document is devoted to the main characteristics of a double-glazed window.
3. GOST 30777-2001 and 538-200. Both texts contain requirements for the quality of fittings.
4. GOST 30674-99 and 23166-99. Two documents describe the main parameters of the product in the assembly to ensure its long-term operation.
5. GOST 30971-2002. The text regulates the requirements for the quality of installation work.

The product must meet all of the listed requirements.

Where are round windows installed?

The installation of small round plastic windows will be appropriate for glazing attic floors and attics - with the help of such structures you can successfully emphasize the curves of the roof, making its vaults more attractive in appearance.

Basement floors where the garage or utility rooms are located, which do not require a large amount of natural light, can also be glazed using round PVC windows. In this case, two goals are achieved at once: sufficient illumination inside the room and minimal visibility of the window from the facade of the building.

Blitz survey: Do you have plastic windows installed in your home? From our previous article you can find out which PVC windows are best installed in your home and why.

Round plastic windows inside a house are often installed on the walls separating rooms , albeit in their upper part - in this way a unified architectural style of the interior decoration of the premises is achieved, as well as additional illumination by natural light of the room located inside the building.

In general, there are a lot of options for using round-shaped plastic windows; the photos located just below fully demonstrate this.

Tips for choosing the right one

It is very difficult to find such a design in finished form, because they are produced exclusively to order.
All leading manufacturers of PVC windows are engaged in production.

Therefore, before placing an application, you need to familiarize yourself with all the features and offers of the seller.

is very important to pay attention to the size of the product. A high-quality round window should not have a radius of less than 40 cm, and an opening model should not be less than 50 cm. Otherwise, the profile will deform.

It is also necessary to check the quality of the plastic. The manufacturer should not have specimens with a yellow or rough surface.

How to measure?

All measurements of the future product must be performed on both sides of the opening - internal (room) and external (street). These parameters are needed to determine the depth of the quarter and all window parameters.

Correct measurements will help identify the skew of the opening, if any. In this case, the size of the product is increased by the amount of the skew. To avoid through gaps, the diameter of the window should exceed the opening by 2-3 cm.

After measurements, it is necessary to make a stencil from cardboard, taking into account the presence of future fittings and bending radius. If you do this yourself, you will have to measure the opening very carefully. If you call a specialist, then in this case the window dimensions will be calculated using formulas.

Important! Any mistakes will lead to the window sagging or cracks appearing.

Round windows on the facade and in the interior

There is no fundamental difference in where to install such a window block, but some options are more preferable:

• On the pediment or attic . A glazing element at the top of the building will look best under a vaulted roof. With this arrangement, the shape of the roof is emphasized and the decoration of the facade takes on a complete look. At the same time, the issue of natural lighting in the attic space or attic room is resolved.

• Ground floor . The implementation of glazing in basements or semi-basements with small round windows is a fairly common option. This not only improves the overall appearance of the facade, but also makes these rooms brighter during the day.

• In the interior walls . Partitions between rooms are usually glazed with solid-type products without sashes, imposts or sashes. This has a beneficial effect on the interior, making adjacent rooms more comfortable and brighter.

• The bathroom is another fairly popular place to install round blocks. A window with a layout, glazed with opaque or frosted glass, would be relevant here. If the interior and facade design allows, you can install a stained glass window.

What it is

A bay window is a part of a building that extends beyond the façade plane and is glazed along the perimeter. A bay window is a system of two or more window complexes combined with each other with a special connector at an angle that is strikingly different from a straight one. Bay windows, as construction projects, are complex. They are available in classic house designs, and on buildings of modern architecture.

According to the form they produce:

• semicircular;
• rectangular;
• corner:
• trapezoidal;
• circular;
• standard.

In French, “bay window” means “embrasure.” Translated from German, it speaks of a “ledge” or “lantern”.
