PVC windows SCHTERN 70 - these are the most popular plastic windows on the modern market, which over the past years have become the standard of quality, comfort of use in a wide variety of conditions, as well as maximum strength and reliability. Of course, the SCHTERN window brand is represented by several models, each of which deserves the highest marks. However, since we are talking about harmony and moderation, including in terms of cost, SCHTERN 70 windows should be specially mentioned here.

So, the SCHTERN 70 window profile is a profile with a width of 70 cm (which becomes obvious from the name) and three air chambers, inside which inert gases such as argon and krypton are traditionally located.

Needless to say, such functional properties as heat preservation, light transmission, sound absorption, room protection and structural strength are at their best in the case of the SCHTERN 70 profile.

Profiles ONLY of the highest class "A"

According to GOST 30673-99 "PVC profiles for window and door blocks" for the thickness of the inner walls ALL our profiles are of the highest class "A" - the thickness of their front wall is not less than 3 mm.

GOST standards for different classes:

  • class "A": front wall not less than 3.0 mm
  • class "B": front wall not less than 2.5 mm
  • class "C": wall thickness is not standardized

Please note that 80-90% of the Russian market is “B” and “C” classes and only 10-20% of “A” class profiles. At the same time, VEKA's assortment includes ONLY A-class profiles.

In principle, we DO NOT use profile systems of classes "B" and "C" (with a front wall width less than 3.0 mm).

PVC window profile SCHTERN FEST 70

PVC windows SCHTERN (Stern) are presented on the market in various price categories, a kind of standard among which is the "Classic" group. The name of this line is no coincidence - we are really talking about the use of classical averaged approaches to price and quality, allowing them to be as harmonious and at the same time optimal combination.

Below we will describe Stern plastic windows of the Classic series with a base profile width of 70 cm. This is a PVC profile SCHTERN FEST 70.

Today, SCHTERN plastic windows are among the most popular, since they are not too expensive in the absence of critical deficiencies in manufacturing and functional equipment.

Plastic windows REHAU

The advantages of REHAU windows are best seen on the example of the most popular series - Rehau Basic-Design. This model has the following parameters:

  • The width of the three-chamber profile is 60 mm;
  • Standard indicators for noise and heat insulation;
  • Windows do not require special care, they are very technological and reliable
  • The main advantage is the relatively low prices for windows from this profile.

They are used for glazing of cottages, balconies and apartments, just like VEKA. However, modern requirements for energy saving provide for the use of 70 mm wide profile systems in construction. Therefore, in the near future, in companies responsible to consumers, the Rehau Sib-Design profile will become the basic option.

PVC window profile SCHTERN FEST 82

SCHTERN profile windows of the "Premium" series are considered today as the most modern, the most aesthetic and, most importantly, the most reliable, comfortable and functional.

Below we describe in detail the Stern profile "Premium" type FEST 82, which, along with the SCHTERN RED model, is a leader in all respects.

The main basic parameters and characteristics that distinguish SCHTERN FEST 82 PVC windows among analogues:

  • Unique SCHTERN design profile with a basic width of 82 mm;
  • Double-glazed window with 2 chambers 40 mm wide;
  • 6 air chambers each in the profile frame and in the window sash;
  • The indicator of resistance to heat transfer processes in the value of 1.38;
  • 3 sealing contours in designer light gray;
  • Unique SCHTERN ROTO window fittings, including, among other things, a special handle for safe self-opening of windows by children;
  • The minimum height of the sash and the minimum overlap, allowing to increase the area of ​​the glazing directly;
  • Additional protection against profile deflection, as well as sagging of the sashes;
  • Lack of exposed metal reinforcement elements.

It is noteworthy that SCHTERN plastic windows are equipped with an energy-saving, multifunctional, or ordinary standard glass unit, depending on the needs of the customer. At the same time, the chambers inside the double-glazed windows are filled with inert gases - a mixture of argon and krypton in accordance with modern technologies. Note that the energy saving properties of SCHTERN FEST 82 windows are on average 2.8 times higher than the standard values.

Finally, the main feature of SCHTERN FEST 82 windows is the maximum opening width in various positions with a huge area of ​​the window structure itself.

Window accessories designed for use with the window system are also included in the SCHTERN FEST 82 package. These include window handles, window sills, slopes, mosquito nets, and a whole range of other elements.

With all this, outwardly, the window can look almost anything, which is achieved by gluing a special film on the profile. Thus, Stern windows of the FEST 82 type can be indistinguishable from wooden windows (moreover, imitation can be made for various types of wood), and can also be fully integrated into the overall design of the interior or the facade of the building.

It is worth, of course, to understand the described window profile - this is not a choice for everyone. It's kind of "window elite". Accordingly, the choice of such models should be deliberate. Usually such windows are chosen for glazing terraces in cottages and country houses, glazing of large office premises, as well as luxury apartments.

MOST DISCUSSED WINDOWS in Lipetsk

We ordered windows for the children's room. We have recently moved to a new apartment. The windows from the developer were plastic, but single-chamber, flimsy. Were blown out. We decided to replace the windows with warmer ones in the nursery. At first, we wanted wooden euro-windows with double-glazed windows. Manager Olga offered Rehau plastic windows with Delight profile, energy-saving glass unit and child locks. I liked the plastic solution. Reviews on the Internet about the Delight profile are only good and technical characteristics inspire confidence. Since they were initially set up for wooden structures, it was decided that the plastic windows would be laminated to look like wood. The windows were made for 12 days, then they were delivered, raised to the floor. The fitters came the next day. I was worried that the editing would take a whole day, but they finished it in 4 hours. The old windows were taken out, new ones were installed. In principle, nothing caused dissatisfaction and I am satisfied with the windows and the work. I can safely recommend the Village company - windows into the house!

"Modern window systems" in Lipetsk, Trubny avenue 7. I do not advise you to contact this company if you want to solve problems with PVC windows, and not get yourself a headache. Those installers who worked with us, apparently, do not know at all which means conscientiousness and quality. I am extremely dissatisfied with the quality of the work. Also, I do not advise ordering an adjustment of the fittings, after that adjustment it blows worse than before. I paid a lot of money, but the problem remained. Money thrown into the wind. Having removed the finishing bar, I found packing film in the corners, instead of foam, and randomly filled seams with polyurethane foam. I do not presume to judge all the installers of this office, but judging by the fact that this is a young company, they could treat their customers better if they want to compete with others.

PVC window profile SCHTERN RED

SCHTERN plastic windows (Stern) are considered one of the best in the entire line of similar products. Moreover, this applies to both the Russian market and the international one.

You can buy windows SCHTERN RED, ordering them for yourself, and at the same time receive an additional set of other services (consulting, measuring the window opening, calculating the cost of plastic windows, delivery and installation of plastic windows with the participation of qualified specialists). At the same time, the price for SCHTERN plastic windows is determined directly by which profile model will be chosen.

The SCHTERN profile is traditionally performed in one of three standard versions: "economy", "classic" or "premium". The latter is, accordingly, the highest quality, the most reliable and the most individualized in terms of design.

The Stern "Premium" profile, in turn, is also represented by several models, the most prestigious and outwardly attractive of which is the SCHTERN RED model.

We would like to draw your attention to the fact that the main feature of the SCHTERN RED profile, reflected directly in its name, is the ability to design in various colors. In particular, the red color of the bead seal is typical. This is a kind of "highlight" of this type of profile. In this case, the space around the contour is made in light gray.

Stern plastic windows are coupled with the use of original window fittings. These are invariably Roto Designo window accessories, which are well-known and quite popular in their own right.

Roto Designo window accessories - visually inconspicuous window hinges of the minimum size, built-in overlays, aesthetic execution of unique SCHTERN handles and plugs, which can also be made in red at the request of the client. The record holder in terms of elegance among the offered accessories is the Roto NT, in which Designo hinges are designed for sashes weighing up to 150 kg.

Separately, we note the presence of a special child lock on the window profile, as well as a lock that additionally protects the room from burglary from the outside.

Stern's plastic profile is always made in an original style, and the window system itself has been repeatedly recognized as one of the best at various international specialized exhibitions. The SCHTERN RED corporate style makes the window unique and attractive, distinguishing it favorably against the general standard background.

Comfort and safety, reliability and the maximum possible number of functions, ease of use and ease of installation are all about Stern Red. In addition to this, it should be noted that SCHTERN RED plastic windows perfectly retain heat in the room, provide decent sound insulation and can limit the penetration of unnecessary portions of sunlight into the room, while guaranteeing the retention of harmful UV radiation by 15%.

In addition, upon your individual pre-order, the SCHTERN RED window can also be equipped with a stylish thermometer.

Why is it worth choosing Stern windows?

PVC windows Stern

Availability.

Window system "SCHTERN" - smooth lines and rounded contours, meets all the needs of discerning consumers. The Stern profile is produced at an enterprise with extensive experience in the production of plastic windows.

Heat.

Thanks to the profile width of 70 mm, it is possible to install a double-glazed unit, optionally 24 or 36 mm, with glass that helps to retain heat in the house. In addition, 3 air chambers and a seal in the glass unit allow you to keep warm in your home. And a snug fit to the glass eliminates blowing and reduces the "edge effect" along the entire perimeter of the plastic window.

Durability.

The service life of plastic windows from the SCHTERN profile is 40 years, the service life of the seal is 30 years in northern and temperate climates. Profile class frost-resistant, temperature range from - 60 ° to + 70 ° С

Safety.

Any type of burglar-resistant hardware can be used with this profile. A bead with a rounded shape, gives an attractive design to the window and has a protective function that prevents the glass unit from being squeezed out. Due to the rigid reinforcement, the anti-burglary properties of plastic windows are increased.

Noise protection.

The wide glass unit and the increased width of the vestibule on the side of the room prevent the penetration of noise into your home. The tight fit of the vestibule along this perimeter of the contour without interruption is another important characteristic of the penetration of noise.

Design.

Glazing bead for all double-glazed windows has a curly shape with a rounded edge. Drainage channels are made on the front side, preserving the aesthetic appearance of the window. The gray-white elastic band gives a light appearance.

Environmental friendliness.

PVC windows from the SCHTERN profile are an environmentally friendly product that is safe for human health.

  • Heat insulation. Hermetically sealed glazing and six-chamber PVC profiles exclude through frost penetration. Heat losses during the heating season are reduced by 25% in comparison with conventional profiles
  • Resistant to high dynamic and static loads. Scientists have developed an additional reinforcing amplifier, which makes it possible to manufacture doors with large linear dimensions from the profile. Products do not change the initial geometry, the tightness of the seal is not compromised
  • Reliability. There is a special gluing of a double-glazed window, which significantly increases the security of the premises from the penetration of unauthorized persons

Reviews of PVC profile SCHTERN (Stern)

Ignat... Stern put the windows, because there were wooden ones in the house on the farm, and through them as much snow fell into the house during strong snowstorms. There were 12 windows. The price suits me completely, everything is fine. After installing the windows, I was surprised that they suppress street noises very well, do not let the wind through. There is, of course, no more snow at home - and even in severe frosts, cold air does not enter the house through the windows. We turn on the heating almost before the new year, but even now, with PVC windows, you can stay at home without any problems. The first time I used windows without any seals supplied by me personally. I am happy with my choice, now I can rest easy.

Ilona... For the summer residence they chose this particular brand of windows - Schtern. The house in the country presupposes a large number of windows, so we decided to choose a not very expensive option, so that it would not be completely expensive in terms of money. And Schtern windows are just economy class windows. But at the same time, their quality suits us quite well. The windows are durable, they have good mechanisms, that is, they open / close easily and easily. For a year of operation, the question has never arisen that it is impossible to open or close a window. We installed single-chamber windows and they are soundproof and do not let water through, and in the cold season, they do not let the cold through.

Negative reviews

Stern from Lipetsk also received a lot of critical reviews about the windows.:

They are wrong with the size and equipment

A good third of the negative statements about schtern profiles are devoted to this problem. One of the guests from the Oknas.ru portal complains: “They brought a window, took out the old one, and began to insert a new one. So it is turned out to be 5 cm more than the window opening... To my questions, what is the matter, they answered that my profile was installed to other customers! Like, he approached them. And it's winter outside, I have no time to wait for another. Thank God, I made an agreement with familiar builders - they enlarged the opening for me. But, gentlemen, you can also go crazy! "

In this situation, of course, the dealer is to blame. But in order not to be left with a hole in the wall in winter, you can measure the window opening yourself, at least from the inside. It is the opening, not the frame. Take several measurements at different points. Before you get the old window out, try on a new one. All its sides should, like family, fit into the opening.

Check for a blocker immediately after installation.This part is located on the vertical side of the sash

One of the users shares: “I installed the Stern window for a long time. Once I checked the fittings: there no slot ventilator or handle blocker... This is the kind of thing that prevents the window from sagging over time. I don't understand why I have an incomplete set? "

Slot ventilation is more often an additional function. If you haven't asked for it, it won't be installed for you. The blocker, too, most likely, is not provided in this company. We advise you to contact the office where you ordered the windows. Most likely, they will agree to install it. Even for a small fee.

Cheap therefore bad

Another third of reviews are devoted to this topic. For example, Mishanya 59 on the Tybet.ru forum writes that Schtern profiles are worse than imported ones, like all Russian ones. Therefore, it is much cheaper.

But here we disagree. After all, many European brands are also produced in Russia. But for some reason there is more trust in them.

Other reviews - about blowing, creaking fittings - we will not even quote. After all, you must admit, this is how they write about each profile. And more often incorrect installation is to blame.

An overview of the types of fittings will help our readers to check the complete set of the window after installation. Suddenly something is missing, but you need it?

And to understand what you need from accessories, see this material.

    We ordered the production and installation of plastic windows for our apartment using the SCHTERN 58 window profile. This profile seemed to us optimal in terms of price-quality ratio. The windows have three air chambers, which provide excellent thermal insulation, and the sounds from the street when the window is closed are practically inaudible. The fittings are also very high quality, all handles work perfectly, nothing wedges or breaks. In winter, the windows proved to be wonderful, they keep warm, the temperature in the apartment did not drop below 23 degrees even in the most severe frosts, although it used to be up to 18 degrees. We are pleased with the new windows.
