The “Brusbox” profile, reviews of which you can read in the article, is a plastic window made from a high-quality polyvinyl chloride profile. This domestically produced product is the fruit of an activity based on a complex of technologies and experience in the production of similar products. The range includes three-, four- and six-chamber systems. In order to make the right choice, you need to familiarize yourself in more detail with the characteristics and consumer reviews.
Reviews of the three-chamber system
The three-chamber profile is characterized by manufacturability, reliability and simplicity. It is suitable for manufacturing the main types of windows and implementing object segment tasks. Consumers like that the profile has internal and external pre-chambers that provide resistance to heat transfer. Buyers most often choose this option, because it is universal, as it is suitable for a wide variety of construction sites and climatic zones. The profile has certain features, which will be discussed below.
How much do we save?
The table above allows us to calculate how much heat will be stored during the heating period, which will become more clear than heat transfer resistance coefficients:
To calculate heat loss, we use the formula:
Q = (Tv – Tot.p.) * Zot.p. * 24/(1000 * R)
Where:
- TV – room temperature (assuming a value of 20 degrees)
- That.p. – average street temperature during the heating season
- Zot.p. * 24 – duration of the heating period in hours
- R is the heat transfer resistance of the structure.
According to SNiP 2.01.01-82 “Building climatology and geophysics”) Tot.p. equal to or lower than -3.6 °C (for Moscow).
The duration of the heating period for Moscow is 213 days (5112 hours).
Heat loss in kW*hour during the heating period
| Type of glass unit | Veka Euroline | Veka Softline | Veka Alpline |
| 4M-10-4M | 436 | 390 | 333 |
| 4M1-10-4M1-10-4M1 | 339 | 310 | 277 |
| 4M1-10-4M1-10-4M1i | 254 | 238 | 218 |
At a price of kWh of 5.38 rubles. (October 2022), savings during the heating period relative to the cheapest profile with a simple double-glazed window in rubles will be:
| Type of glass unit | Veka Euroline | Veka Softline | Veka Alpline |
| 4M-10-4M | +247 | +554 | |
| 4M1-10-4M1-10-4M1 | +521 | +678 | +855 |
| 4M1-10-4M1-10-4M1i | +979 | +1065 | +1172 |
It should also be taken into account that the second component of savings due to the use of high-quality double-glazed windows and profiles is the reduction of heat flow into the room in the summer, which helps to significantly reduce air conditioning costs.
Characteristics of a three-chamber profile
The three-chamber Brusbox profile, which has only the most positive reviews, has a design width of 60 mm. The seal is double-circuit, and the overlap of the sealing elements is 8 mm. The clearance is 12 mm, while the rebate gap is equivalent to 3 mm. The axis of the locking device is shifted by 13 mm, and the overlap height is 20 mm.
Many experts are also interested in the height of the glazing bead; it is 18 mm. The maximum possible filling thickness is 32 mm. If the profile does not have reinforcement, then its heat transfer resistance is 0.76 m2C/W. The window can be assembled in different modifications, but the sound insulation in each of them is 46 dB.
Number of cameras
Brusbox offers three types of profiles. REHAU has more of them.
Economical solution Brusbox Aero 60-3 - a profile with three air chambers and an installation width of 60 mm..
The German manufacturer with factories in Russia has a similar solution, only it is presented in a wider range: Basic Design, Euro Design, Blitz New.
In terms of assortment, REHAU wins by a slight margin, since its profile in this price segment is considered less fragile, more reliable and inspires more consumer confidence.
Reviews about the four-chamber profile
The Brusbox four-chamber profile, reviews of which will be useful to read before purchasing a product, is not only a universal, but also a high-quality system that is affordable. According to buyers, this profile has a fairly high level of consumer characteristics. It can be used for objects from panel houses to luxury cottages. Buyers especially like that this profile is characterized by one of the outstanding heat transfer resistance indicators in its class.
Benefits of the Rehau profile
This German brand has been producing profiles for more than half a century. The company has been present in Russia for twenty years. Production facilities are located in Ramenskoye and Gzhel, representative offices are open throughout the country. Factories produce profile structures using original German technology, strictly observing the technical process, which has a positive effect on quality.
Brand advantages:
- continuous improvement of products, search for new solutions;
- sound insulation reaches class IV, which significantly reduces the audibility of street noise in the rooms;
burglary-resistant fittings are supported;- each profile system, regardless of the price segment, meets the requirements and standards;
- smooth, easy to clean plastic;
- environmental Safety;
- durability.
Reliable imitation of wood or metals is supported. If the operating rules are followed, the service life of the profiles reaches 60 years.
Specifications
The four-chamber Brusbox profile described above, reviews of which are generally quite good, has almost the same characteristics as the three-chamber profile. The only difference is in the number of chambers, as well as in the heat transfer resistance, in this case it is 0.82 m2C/W, which also applies to the profile without reinforcement. Sound insulation remains at the same level.
Calculation of window heat transfer resistance
To calculate the total heat transfer resistance of a window we will use this formula
R = ( Rп* Sp+ Rс* Sc)/ Sc+ Sc
Where:
- Rп – heat transfer resistance of the profile
- Rс - heat transfer resistance of a double-glazed window
- Sp – profile area
- Sc – glass unit area
Window heat transfer resistance calculations
| Type of glass unit | Veka Euroline | Veka Softline | Veka Alpline |
| 4M-10-4M | 0,42 | 0,47 | 0,55 |
| 4M1-10-4M1-10-4M1 | 0,54 | 0,59 | 0,66 |
| 4M1-10-4M1-10-4M1i | 0,72 | 0,77 | 0,84 |
From the table above it can be seen that the profile has a much smaller effect on the heat-saving properties of the window than a high-quality double-glazed window, this is due to the fact that the area of the profiles is much smaller than the area of the double-glazed window (about 30% of the area of the entire window), and heat loss through poor the glass unit will be significantly larger, even than through the most budget profile.
Therefore, using the most expensive profiles is not advisable; the best solution would be to spend this money on improving the double-glazed window.
It should be understood that the quality of the window and its heat-saving properties largely depends on the capacity at which the window will be produced, even with the best materials, but outdated or incorrectly configured equipment, unskilled workers and incorrect installation can get a very mediocre result.
It should also be noted that you should not skimp on fittings and seals; the thermal insulation qualities and how the windows will behave during operation directly depend on them.
What are the minimum values of heat transfer resistance for windows in the Moscow region:
In accordance with SNiP II-3-79, the basic value of heat transfer resistance is GSOP (heating period day), which is calculated by the formula
GSOP= (Tv – Tot.p.)Zot.p.*
*coefficient designations are deciphered in the paragraph “How much do we save”.
For Moscow in accordance with SNiP 2.01.01-82:
- the duration of the heating period is 213 days;
- average temperature during the heating period Тom = - 3.6 оС;
- GSOP = (20 + 3.6) 213 = 5027
Accordingly, the minimum value of R is about 0.55 m2оС/W, which corresponds to most of the options given in our table.
Reviews about the six-chamber profile
The Brusbox-70 profile, reviews of which can help you make the right choice, is a product of the latest advances in the development of ideal systems. Buyers are attracted by the increased installation depth of the box, which reaches 70 mm, as well as the maximum possible number of cameras, which is six. Thanks to this, according to consumers, it was possible to achieve increased sound absorption and thermal insulation.
Types of profile systems
Let's look at the types of profile systems that are included in the BRUSBOX brand range.
ACLASS
This type of window profile appeared on the market just a few years ago, it was immediately classified as class “A” (as you might guess from the name). The production of the ACLASS model was carried out on the basis of the official GOST 30673-2013.
As for the appearance of the profile, it has a simple and minimalistic design. The ACLASS type is suitable for window structures of all basic types and shapes. At the same time, the distinctive characteristics of the product include the fact that it has an increased wall thickness, and accordingly, the thermal insulation indicators are high.
In this regard, it is recommended to install the system in regions characterized by rather harsh climatic conditions. The design of the profile model includes 3 chambers.

Users note the attractive appearance of the GLIDE profile from BRUSBOX. The heat transfer resistance indicators of this model are at the level of 0.73 m2×°C/W (it is also important to note the absence of reinforcement).
Thanks to such a wide variety of types of window profiles from BRUSBOX, each user will be able to choose an option that will fully meet his needs and wishes.
Specifications
The characteristics differ only in the design width, which is 70 mm, as well as the maximum filling thickness, in this case this parameter is 40 mm. When considering this “Brusbox” window profile, reviews of which will certainly help you make the right choice, it is also important to pay attention to the possibility of laminating the profile. Window sills can also be covered with film, as a result of which they take on different shades. The film is a high-tech material that can increase aesthetic appeal and impact resistance. Now your windows may differ from traditional white ones.
Advantages and disadvantages
Brusbox plastic windows are made from window profiles reinforced with metal inserts, which increase the overall strength of the structure and eliminate the possibility of temperature deformation. Their advantages include:
- An attractive price compared to competitors, making a quality product accessible to a wide range of consumers.
- Good thermal insulation characteristics. This is important for normal operation in regions with cold climates.
- A decent level of burglary protection, making it difficult for attackers to enter apartments.
- Wide selection of fittings offered in different configuration options.
- Durability.
Flaws:
As for the shortcomings, only one of the significant ones has been identified. No matter how attractive the new Brusbox windows may look, reviews left on the Internet indicate that over time the surface of the profile turns yellow, losing its original whiteness. We can only hope that this problem will be resolved soon.
General product reviews from professionals
Experts quite often recommend the Brusbox PVC profile, reviews of which you can read in the article, for the reason that its fittings can be combined with fittings from any manufacturer. This feature can be called a great advantage, because the consumer does not have to limit himself when choosing locking elements, as well as handles. Their appearance may be unique.
Many professionals consider noiselessness and thermal insulation to be the main advantages. It is impossible not to mention the affordable price, because the products are produced in Russia. If the family is disadvantaged financially, then it is worth choosing the Brusbox profile, because it can be installed not only on windows, but also on a balcony, loggia and terrace.
According to experts, they were pleasantly surprised by the quality of the windows when they were tested at low temperatures. The structures ensure tightness and do not allow drafts to pass through. In conjunction with this profile, you can use a mosquito net; no additional money is required for this, because the components are supplied included.
Benefits of Brusbox
The domestic company opened in 2003. Window profile systems are produced on the basis of German technologies, adapted to the climatic conditions of Russia. The plant is located in Bryansk. European raw materials are used in the production of windows.
The main advantages of the brand:
ability to compete with European manufacturers;- the windows can withstand gusty winds and severe frosts;
- due to the presence of Eurogrooves in the window system, any third-party fittings are supported;
- In addition to swing doors, there are sliding models;
- Protective measures against hacking are supported;
- profiles can be laminated to imitate wood or other materials;
- low price.
The prevalence of this brand among Russian residents is not inferior to other manufacturers.
Reviews about the Brusbox Aero profile
“Brusbox aero” - a profile, reviews of which see below, is a design limited in the size of the sashes. The maximum profile length for a white structure is 4 m; if we are talking about a colored version, then this parameter is 2.5 m.
Consumers emphasize that these values are quite sufficient to fill window openings of standard sizes. However, if necessary, you can order a profile with more impressive parameters, and it will contain joints that are made in the form of expansion joints. The design of the latter will guarantee the movement of the profiles in a certain range. The described “Brusbox” profile windows, which receive the most positive reviews from consumers, are additionally reinforced with reinforcing elements laid around the entire perimeter; they take the form of galvanized steel profiles, the wall thickness of which is 1.5 mm.
Consumers like this, because in this case the profile will not be afraid of loads and pressure. If you want to use less intensive reinforcement, for example, one that will have a wall thickness of 1.2 mm, then experts recommend confirming this data with strength calculations.
Double-glazed windows and their choice
The standard configuration contains double glazing. A single-chamber double-glazed window with a thickness of up to 26 mm is suitable for unheated rooms where there is no need to retain heat. A double-chamber double-glazed window is installed in central Russia; it does not allow sound to pass through and has high thermal insulation properties.
If you have additional wishes for glass, you should take this into account when ordering. Silver coating gives the glass unit better thermal insulation properties. And the so-called “Quiet package” is created using several glasses of different thicknesses, which has a good effect on sound insulation.
If it is important for you to protect your home from intruders, choose a three-chamber double-glazed window with ultra-strong characteristics. For fire protection properties, a thin metal mesh is inserted into the glass. And mirrored windows will prevent curious people from looking into your home from the outside.
Reviews of Brusbox windows from the point of view of operation
The Brusbox profile, reviews of which you could read from professionals above, is purchased and used by ordinary consumers. According to them, it is much easier to care for such systems than those made of wood. This is known to everyone who has at least once prepared a wooden profile for winter, washed it and sealed the joints.
Buyers today increasingly prefer a plastic profile, because it does not need to be not only sealed and insulated, but also painted. Over time, the surface of the material does not deform or turn yellow, and also retains its appearance for many years, because the profile has a special chemical composition that steadily withstands aggressive climatic conditions.
Consumers are advised to regularly wipe the frames using a mild cleaner or a special window care composition. Maintenance will be easier, because the profile has a flat, smooth surface. Operation consists not only of periodically wiping the profile, but also of lubricating the moving elements of the fittings. Seals should be washed with clean water and then lubricated. By performing such simple operations, the consumer is guaranteed the durability of the windows for many years.
Key differences between window products
The windows of both companies are easy to open, do not fade in the sun, and do not require special care. The key difference is the price. Timberbox belongs to the economy class, although the profiles are made on imported equipment from imported raw materials. Rehau's production technology is almost identical, but the cost of this company's offerings is 15-20% higher. The reason is customs duties and fees.
Solutions from both brands are suitable for installation in apartments and houses, even in difficult climatic conditions. However, the German brand is considered more ergonomic. It also offers more design options: Rehau has rectangular, beveled, smoothed and curly beads, as well as solutions with a premium look.
Reviews from experts about window profiles and double-glazed windows of the Brusbox brand
The window profile bends under the influence of temperature stresses, its own weight and wind loads. For reliable and durable operation, methods of fastening double-glazed windows must exclude the transfer of loads. According to professionals, compensation gaps are installed between the binding and the Brusbox glass unit, in which special gaskets are located.
According to their purpose, according to experts, they are divided into fixing and supporting. The latter are necessary to transfer loads from weight to the binding. The fixing ones guarantee the centering of the glass unit in the cell and prevent the product from moving when the sashes are opened.
Which windows are the most popular?
If we discard all the drawn ratings from companies that benefit from selling this or that profile, then the most revealing will be a cross-section of queries in Yandex and a popularity rating from Google Trend.
We conducted a sample across the CIS and the most popular brands today turned out to be Rehau, Veka, KBE, Brusbox and Deceuninck; other brands are in much less demand.
If we build a diagram based on the collected data for these brands, we get the following picture:
At the same time, the market share of Rehau and Veka is simply huge; these two companies are currently the most popular in the post-Soviet space, despite the fact that there are quite a lot of alternatives on the market that are not inferior in quality and are slightly better in price.
Statistics were collected based on Wordstat Yandex
The images show statistics of queries in Yandex for the month for Russia and the CIS countries; you can also add ~50% of queries from Google to these values, since the share ratio of these two search engines in the CIS market is approximately 50 to 50.
