Box width, thermal insulation, wood breed and other characteristics that are important when choosing.
The windows made of modern design isolate heat and the sound is not worse than plastic, while they are stronger, so the flaps do not play when opening, more rarely savage and better resist hacking. The estimated service life of a high-quality wooden window with an aluminum overlay on the lower frame profile exceeds 30 years. Alas, there are wooden windows by 40-50% more expensive than plastic (in the last 2 years, the break in price has increased, since PVC products, unlike wooden, almost do not rise). In order for the increased costs justified itself and did not have to regret the purchase, it should be formulated in advance to formulate the requirements for new windows and carefully treat the quality of their manufacture.
The windows must first provide comfortable accommodation in the apartment, so it is necessary to pay attention to the technical characteristics of the structures. Then you can estimate the quality of the finishes, decide on the color, drawing of the binding, form of the frame profile.
1 Box width
In order not to make a mistake with this parameter, it is necessary to know the material of the walls of the house - this information is easy to learn from the developer or simply on the Internet (focusing on the series and time of construction). Walls of multi-storeys are different in the heat insulating properties, and in the window of window openings can occur the bridges of cold, which lead to the freezing of slopes.
As a rule, in modern houses from three-layer panels, as well as frameworks in the middle band conditions, you can install conventional windows with a box of 60-78 mm wide. For an apartment in a house of tight reinforced concrete panels and a single-layer brickwork, it is extremely desirable to install windows with a wide (more than 80 mm) box. Otherwise, there is a risk of overwhelming internal slopes and the formation of mold. It is worth paying attention to the Finnish type design with double separate-paired flaps and a box of 90-110 mm, which perfectly protects the slopes from the freezing. True, the price of 1 m2 of such glazing will cost no cheaper than 13,000 rubles. And on the washing of the glass with separate sashs will have to spend twice as much time.
2 Heat insulating properties
This parameter should pay attention if the apartment does not sleep well or has cold walls. Then you should purchase windows with energy-saving double-glazed windows (with two cameras filled with inert gas, and internal low-emission glass). In this case, the width of the frames of the frame and the sash should be at least 78 mm, and the heat transfer resistance of the entire window (this parameter, indicated by RO, is always indicated by the manufacturer - from 0.60 m2 • ° C / W.
In the compartment system, the profiles of the boxes and sash are in the same plane.
The most popular system is 78 mm wide.
For an apartment in an old house, you need windows with a wider box.
But even if with old wooden or "Luzhkovsky" plastic windows in winter, the temperature in the apartment does not fall below +20 ° C, it is unlikely that it makes sense to buy new designs with improved heat insulating properties. It is enough that the value of RO exceeds 0.55 m2 • ° C / W. The optimal is a two-chamber double-glazed glass with a thickness of 32 mm with conventional stools.
At the "Scandinavian" window, the sash consists of two paired parts (in the outer - glass, in the inner - double-glazed glass).
The usual "eurowindow" with single flaps is colder, but it is easier to care for him.
3 Soundproofing
If the facade of the house goes to the street with a lively movement, and even more so "flying" highway, then the windows have increased requirements for soundproofing. The cheapest solution to the problem of transport noise is the installation of asymmetric sound-proof two-chamber glass windows (outer glass of 6 mm thick, the remaining two - 4 mm), but the noise decrease will be on average 37 dB, and this may not be enough. Much better windows with an acoustic triplex. They reduce street noise at 40-45 dB, however cost almost 3 times more expensive. A good sound insulation (up to 48 dB) has already mentioned "Finnish" windows, but only if the seal contour is provided around the perimeter of the outer flap (it is often absent from the budget products).
Windows, opening out, in many cases is more convenient than usual, but are much more expensive, as they should be equipped with a stroke limiter, sliding rotary loops or self-cleaning glass.
4 Ventilation of rooms
The accessories of the wooden window (as, however, and plastic) can be adjusted so that the sash is not very tightly lightened to the box and passed the air. Some experts even advise in the spring to increase the inflow, and to reduce it for the winter. But this, of course, is inconvenient, besides, not all accessories are adjusted easily and accurately, and most importantly - such ventilation is discomfort: cold air breaks through the entire perimeter of the sash, and there is a draft. It is much more correct to acquire structures equipped with accessories with a micronizing air function, in which the clearance is formed at the top of the sash (the price of the option is from 2 500 rubles.). Another acceptable option is the installation of the supply valve, also the guide stream of cold air mainly under the ceiling. The valve with installation will cost 4,000-9,000 rubles. Depending on the model. The performance of folding models is low - up to 7 m3 / h, and slotted - up to 40 m3 / h (as a rule, it is enough for the bedroom).
Connection of brucks Rams on a straight spike is considered the most reliable
Connection of brucks frames on straight thorn
In some structures there is an overhead outdoor flap of plastic or aluminum. Such windows reduce the transport noise at 42-45 dB.
The bottom of the box most suffers from moisture most, and its protection of the metal lining will increase the service life of the window much, while the price of the option is only 1,000-1,500 rubles. outside the window.
5 design and finishing
Forms of the section of the bars of wooden frames are much more diverse than plastic. With the help of shaped cutters, you can round the edges or remove direct chamfers, make curly longitudinal grooves and protrusions. Some companies (for example, the "windows factory" or "growth windows") offer more than five options for cross-section of framework parts.
The tree is almost not subject to thermal expansion. This is an excellent material for large-sized structures, such as folding balcony doors.
Their flaps are connected to each other loops and equipped with a guide roller.
In addition, a clamping mechanism is installed on each flap, so that such a partition door protects well from noise and drafts.
The windows of pine and larch usually paint alkyd enamels or covered alkyd-urethane varnishes with a UV filter, products from valuable wood today are often impregnated with special oil (Danish Oil and analogs). Varnish and oil emphasize the natural beauty of the tree, but the projects of urban homes are usually provided on white windows. If you want to preserve the texture of the tree on the side of the room, you can order a coloring of enamel outside and varnishing from the inside. The cost of this option ("bilateral coloring") - from 2 000 rubles. Behind the window, the pine or larch toning or larch will cost in a three-dimensional color. The box of the box can be equipped with an outer aluminum overlay. The full aluminum salary on the frame and the sash will increase the price of the product by 40%, but in the conditions of the city by half the window life will extend.
6 Wooden Breed
Most of the companies offer windows from a tree of three breeds: pines (from 9,800 rubles / m2 of a single swivel window), larch (from 11 500 rubles / m2) and oak (from 16 500 rubles / m2). Larch products are more durable than pine, advantages of oak frames - decorativeness and high strength. Some firms on the request make windows from the tree of valuable and exotic breeds - red cedar, Merbau, American walnut, etc., the price of 1 m2 of which starts from 30,000 rubles. No less impressive looks at the same time, it is much cheaper (from 18 000 rubles / m2) products from a combined bar, which has a valuable wood used only for lamellas facing the room.
For balcony glazing, double-hearted windows with single-chamber windows can be used.
Or light designs with frequent binding and single glass that produce small carpentry workshops.
Bonus: How to check the box already purchased?
When you deliver ready-made windows, do not rush to sign the acceptance act - first carefully inspect the designs. As a rule, after editing, the claims to their appearance are not accepted.Typical Wooden Ram Defects
- Zadira, chips, non-stated places in the area zone say that the firm uses outdated equipment. These defects may affect the tightness of the window and will interfere with the care of it.
- The gaps between the corners in the corners occur with the inaccurate milling of the spike and the groove and reduce the strength of the compound. Details should be tight, without the slightest gnesks to adjoin each other. There should be no traces of the shtlock.
- A large number of splices on a microship, covered areas indicates that low-grade lumber was used for facial lamellae. It is also impossible for products from pine and larch the exterior surfaces had a pronounced pattern.
- The plugs on the site of the cut out defects are also undesirable, since, first of all, the plug is always noticeable, because the fibers in it are directed differently as in the slave. In this case, the plug otherwise reacts to moisture drops and with time it begins to rise above the surface or, on the contrary, placing.
- Thots, frozen drops, color unevenness talk about breach of painting technology. With proper application of a multilayer coating, it turns out perfectly even and monophonic.
