Retail and wholesale of metal-plastic and aluminum window structures in the Russian market is engaged in the network company Bisector. Reviews about the windows of this company are different, but one thing is certain - the products of this company are in demand in St. Petersburg and beyond.
What is this company?
The company producing and selling Bisector windows is one of the largest enterprises in the industry in the Northwest region. The company was established in 2002, at the first stages of the formation of the Russian market for metal-plastic constructions. For several years of its existence, the company managed to achieve tremendous success and establish itself as a leader in the manufacture of windows in St. Petersburg. The bisector, as its management positions the company, is:
- modern high-tech production, equipped with automated advanced equipment from the best European manufacturers;
- more than 15,000 sq. m top quality products monthly;
- a large number of qualified personnel;
- own fleet, testing center, quality control department.
The company also relates to its advantages an affordable price category of manufactured products. The quality of the plastic windows "Bisector", according to customers, adequately competes with German-made products. According to experts, the Russian company creates window structures that are in no way inferior to foreign counterparts.
Innovations in the world of windows of St. Petersburg
A distinctive feature of the company is its business strategy. The Bisector windows factory is constantly striving to introduce innovations and advanced technologies already used by foreign manufacturers. So, for example, in 2005, the St. Petersburg company became one of the first companies in Russia to use energy-saving double-glazed windows when creating structures. Over the past ten years, all the plastic windows of the Bisector have been manufactured using energy-saving systems.
A kind of technological breakthrough was achieved in 2011. It was marked by the manufacture and installation of the VEKA SLDIE lift-slide portal. If you believe the reviews, the windows "Bisector" perform their functions better if they were installed by the manufacturer, and this is not accidental. It turns out that from 2010 to the present day this company offers a unique installation technique. During the installation of the product, the opening is carefully leveled and waterproofing tapes are used that provide the function of climate control in the room.
The basic principles of the company
The widest assortment of manufactured products is far from all that the company offers its customers. The advantage of the company "Bisector" is to provide quality service, including the provision of consulting assistance, professional installation of new and dismantle of old products, comfortable payment methods, subsequent preventive maintenance and repair.
Over the years of successful development, the company has developed the primary principles of activity, which are as follows:

Difference of windows "Bisector"
Plastic window structures have long ceased to be considered something expensive and luxurious. Today, the purchase and installation of PVC systems is nothing but a vital necessity. Thanks to the plastic windows in the house, it is possible to create the most cozy and comfortable atmosphere. The effect is achieved due to the specific properties of metal-plastic structures. Even the cheapest PVC windows guarantee a certain level of noise and heat insulation.
According to reviews, the windows from the "Bisector" are really high-quality products. Firstly, PVC structures are resistant to ultraviolet rays, moisture, fungi and various microorganisms, since only modern technologies are used in their manufacturing process. Secondly, no one doubts the aesthetic properties of products.
It is not surprising that the windows manufactured by the Bisector company in St. Petersburg are in demand among the population. The success of the enterprise is due to the use of high-precision modern equipment from Germany in the production process. In addition, each finished product undergoes several inspections with the aim of quality control. Unlike competitors, the company specializes not only in the production of metal-plastic, but also wooden window structures.
Seamless PVC systems have become a kind of know-how in the Russian market of plastic windows, which was one of the first to be introduced by the St. Petersburg company. Thanks to the use of high-tech machines, the Bisector produces products with the smallest possible joint thickness (approximately 1 mm), therefore the junction of the profiles is imperceptible to the naked eye. In addition, the creation of a window structure of the correct geometric shape is ensured, in which the likelihood of even a minimal skew is eliminated. The manufacturer succeeds in achieving this thanks to the four-head welding technique.
The subtleties of production
In 2010, for the first time, an automated line was launched for the production of double-glazed windows, PVC and aluminum cases using Rotox equipment (Germany). Thus, a single flow-welding line for the production of PVC frames and sashes, including a Rotox saw, a four-head welding machine and a cleaning machine of the specified German brand, began to operate at the Bisector windows factory.
In the summer of the same year, the company managed to pass a comprehensive certification of St. Petersburg window production for compliance with the VEKA Group Technology Code, which gave Bisectorice the right to use a branded German profile. The workshops use only environmentally friendly and clean materials that have all the necessary permits.
To produce branded seamless designs, it is necessary to weld the frame contour with the flaps simultaneously at four points along the perimeter of the frame. It will depend on the accuracy and evenness of the weld whether the finished product will receive perfectly right angles and whether its service life will be long.
In addition to operational characteristics, German equipment provides Bisector windows in St. Petersburg with excellent aesthetic indicators. Factory production here is 90% automated, and therefore any roughness and roughness of the weld are excluded. Today, the company managed to achieve mass production of PVC systems with a weld of less than 1 mm wide - it is almost impossible to notice it.
How is the strength and reliability of future windows ensured if the seams connecting the frame and sashes are so thin? The quality of welding is determined by the temperature of the welding plate, which may be different for each type of profile. However, if the machine is not warm enough, the junction will be weak, and if the temperature is too high, soot will appear on the profile, which will ruin the appearance of the product. On the automated lines of the Bisektrisa factory of metal-plastic windows, the temperature of the welding plate is set automatically: in case of exceeding the norm or, conversely, lowering, the machine will simply turn off.
In 2012, the company manufacturing plastic windows began to introduce the new True Connect technology into the production process, which implies the use of fluoroplastic liners to fix the impost instead of standard aluminum corners. This change allows you to minimize the risks of chips and cracks in the double-glazed window, to get rid of the so-called cold bridge inside the PVC window system.
Which profile to choose
The type of PVC profile is the first thing that matters when buying a plastic window. Judging by the reviews of the windows of the company "Bisector" in St. Petersburg, each client is offered to choose from several classes, depending on the thickness of the outer wall. Thinner profiles have a lower price. It is important to understand that such designs do not guarantee decent noise and heat insulation, durability and correct geometry. The “bisector” in the process of manufacturing window or balcony systems mainly uses class A profiles.
Consumer characteristics of a plastic window are also determined by the mounting width of the frame. The possibility of installing a multi-chamber double-glazed window depends on how wide the profile will be. The company produces custom-made windows, so the profile is made in different sizes, but, based on the reviews, Bisector windows in St. Petersburg are most often ordered with a standard size profile: 58 or 70 mm. Recently, however, wide systems (82 and 90 mm) have become more and more popular, providing greater noise isolation and heat saving.
The second important criterion is the number of air chambers. These peculiar cavities, between which vertical partitions are installed, are the internal filling of the profile. Each of the air chambers, which cannot be less than three, performs a certain function:
- the first is needed to remove condensate;
- the second is necessary for the location of the reinforcement;
- the third is designed to fix fittings and provide additional air gap and maximum tightness.
The 58 mm wide profile has three air chambers. In the VEKA product range, this profile width is used in Euroline window systems. With an installation width of 70 mm (VEKA Softline), 4-5 air chambers are installed, and at 82 mm there can be a maximum of seven. You can calculate their number on the horizontal axis. The width of the profile and the number of air chambers are two indicators that depend on each other. An increase in the number of internal cavities with a minimum width cannot improve the basic consumer characteristics of window systems.
When choosing plastic windows, it is important to check with the consultant not only the number of cameras in the structure, but also the width of the installed profile. Inside, it can have metal reinforcement made of galvanized steel, without lead. When using this material, rigidity, shape stability and structural strength are increased, and the profile itself does not rust from the inside.
Double-glazed windows from the company "Bisector"
The main properties of the window are the provision of natural lighting in the room. However, today a window is not only a translucent opening in the wall. It is a complex engineering design consisting of several elements that guarantee the maintenance of a home microclimate and protection from street noise. And since the quality and characteristics of the individual elements determine the quality of the finished product as a whole, it is important to understand the criteria of the remaining components of the window structure.
What double-glazed windows are used when creating the “Bisector” windows? According to reviews, in St. Petersburg, this company uses only polished glass, often with sun protection. This is confirmed by information on the official website of the company. The manufacturer recommends not to save on the quality of double-glazed windows, since cheap Chinese glasses can subsequently be scratched, cloudy and even crack in frosty weather.
The company “Bisector” offers “smart” double-glazed windows with energy-saving properties. Such complexes consist of multi-functional glasses that can not only retain heat in the room, but also keep the temperature at a certain level, preventing overheating. According to customer reviews, the Bisector windows with energy-saving double-glazed windows are much better at holding heat in the winter season compared to conventional PVC systems from other manufacturers, and in the summer they perform the function of climate control and solve the problem of stuffiness, without interfering with daylight. It is also interesting that a single-chamber double-glazed window of this brand weighs much less than a conventional double-chamber.
Window fittings
Another important element in the finished structures is accessories. Judging by the reviews of the company "Bisector", good quality components are installed on the windows. They open and close without problems in the warm and cold season, protect against the penetration of dust and street sounds. The use of cheap rubber seals, handles, rotary fittings and fasteners will nullify the quality of the entire window system, even if made from a first-class profile. The cost of such products is much lower, but none of the manufacturers will guarantee that such a window will serve for many years.
Reliable fittings do not allow the glass unit to sag, because the thicker it is, the greater the weight of the entire window structure. Sometimes its mass is more than two tens of kilograms. The windows of the company "Bisector" in St. Petersburg, according to reviews, have already managed to show themselves in many years of operation. The percentage of breakdowns is minimal - in most cases, designs work fine, open and close without squeaks, gum does not sag, handles do not jam. And this despite the fact that some products were installed more than five years ago.
Installation work
No matter how high-quality plastic windows are, improper installation can cross out all the efforts of the manufacturer. Only high-quality installation is a guarantee of durability and maximum functionality of the window structure. When purchasing Bisector windows in St. Petersburg, it is undesirable to install them yourself; it is better to use the services of company employees. Since the company values its reputation, the installation team will do everything possible to prevent complaints from the client. In addition, we should not forget that when applying for a service for installing windows to third-party organizations or trying to perform installation on their own, the buyer automatically deprives himself of the right to warranty service of the purchased products in the future.
When purchasing Bisector windows, the client is also offered services for installing slopes with connectors. This installation method differs from the usual one in that in the working process the start profile is laid on the slopes without the use of silicone, which guarantees the preservation of a fresh, neat and pleasant appearance of the window for a long time. Installation work by the team is carried out according to the following algorithm:
- Preparing for installation. Before dismantling old window structures, a specialist prepares an opening and re-measures the dimensions of the product. If the parameters match, the old window is cleared. The frames are sawn and put into bags for construction waste.
- Installation of the window in the opening. Using plastic wedges, the structure is fixed in the opening to the anchor plates. The team of the company "Bisector" installs plastic windows using tapes PUL or PSUL.
- Foaming seams. Along the perimeter, the space between the profile and the wall is filled with construction foam or insulated with VUL, PUL or PSUL waterproofing tapes. In a standard installation, the tape is glued only for drainage, and the joints inside and outside are sealed with plaster.
- Drainage. Next, a drainage installation is carried out, under which, regardless of the type of installation, it is necessary to put a VUL tape - it will protect the installation seam from street damp.

It is difficult to unequivocally answer this question, how much do window systems cost. The price of the finished product depends on a number of factors: the size of the opening, the installation width of the profile, the quality of the glass, the energy efficiency class, etc. In St. Petersburg, the Bisector window of the budget category will cost the customer a total of 5200 rubles, and the cost of more expensive models starts from 10 thousand rubles The company guarantees the quality of any product in the range.

What customers say about the company’s designs
Most of the reviews about the "Bisector" windows in St. Petersburg are confirmed by the specifications declared by the manufacturer. At the same time, there are a lot of negative feedback about the poor quality of work organization, the inadequate mechanism of interaction between employees and customers.
Most often, people complain about late orders. The Contractor may delay the delivery of finished products for several days or weeks, while no compensation and bonuses in case of delay for customers are not provided. Instead of elementary apologies for the delay in the manufacture of windows, according to reviews, Bisector employees nervously point to a special clause in the contract, printed in the smallest font. Having studied it, many customers, to put it mildly, are surprised: it turns out that the agreement concluded between the customer and the company really regulated the legal right of the latter to delay deliveries and installation of windows. Undoubtedly, this fact testifies to the professionalism of the firm’s lawyer, but not to the fact that the company cares about the interests of customers, its own image and reputation. Thus, in their responses, people warn that turning to Bisector may turn out to be a loss of time, money and nerves.
Based on the reviews, evidencing the experience of cooperation with this manufacturer, the problems in the operation of improperly installed window systems are confirmed. It is possible that violations during installation work are not systemic, but who wants to spend the money with the risk that soon they will have to prepare for repairs again?
On the other hand, users note a number of advantages of Bisector products. In particular, the ability to install reinforced hardware for increased protection against burglary is of great importance. To prevent the possible unauthorized entry into the house of robbers through the window, the structures are easily equipped with locks for window handles, shock-resistant double-glazed windows and other durable fittings. The windows of the company "Bisector" allow you to feel completely safe.
