question the quality of plastic windows for the consumer is paramount, as the window construction are established not for one year, but for a couple of decades at least.Quality windows should definitely keep heat in the house, the room is well transmit light, reduce the level of noise that enters from the street, close tightly and be comfortable to use.Therefore, it is important to know how to distinguish good quality plastic windows from PVC made from second-rate material.

StandardsQuality plastic windows
sign of high-tech production of plastic windows is the fact that the manufacturer of the certificate DIN EN ISO 9001. This monitoring system ensures the maintenance of stable properties at the appropriate level and that the product meets all the standards of qual
When buying plastic windows is recommended, above all, pay attention to the profiles that are used in their manufacture.The world market is currently represented by several varieties of profiles, which are brand name manufacturers: This German quality windows REHAU, profile VEKA, profile PROPLEX, profiles TRYBA and KBE.The main difference between the profiles of different brands is the production of plastics compounding.
main problem of poor-quality profiles is their inability to solve the problems associated with providing reliable isolation of residential premises in the street against the penetration of cold and extraneous noise.Poor-quality profiles of plastic windows will be blown through all the winds.
heated during the manufacture of PVC window profiles is passed through a special form.The result is a hollow profile, chambered jumpers.So you have to decide when choosing plastic windows with the number of internal chambers in the profile - through holes, which are designed to act as a peculiar air bags.Often, within the chambers of plastic windows is a layer of insulation.
According to building codes, in a residential area is allowed to use at least three-chamber PVC profile.The two-chamber PVC profile can only be used for glazing residential rooms.However, the number of chambers in the profile is not limited to only three, typically this figure is just beginning.Today, manufacturers of plastic windows start to build up in plastic profiles the number of cameras, offering a five-chamber profile.
The greater number of chambers in the profile and, consequently, air gaps, the plastic box, ultimately prove warmer.How many cameras should be in the window profile should be resolved on the basis of climatic conditions.The colder it is, the more cameras you want.However, five-chamber profile is still advisable to put only in the Far North!
number of producers, on the contrary, instead of increasing the number of cameras, taken to put an extra frame for thermal insulation.Since the plastic itself can not withstand a heavy load, the PVC profile made reinforced by inserting a metal frame (reinforcing loop) into the profile.For this purpose, typically applied widest central chamber.
Metal should not be less than 1.5 millimeter thickness.The best material for creating a reinforcing profile - galvanized steel, in which case the window to withstand high loads.When using a simple steel from drainage over time there may be red streaks.Has the value and shape of the reinforcing profile is considered the ideal closed loop which in cross section is a square.It is also often used for the reinforcement and the U-shaped profile.
next thing that affects the quality of plastic windows is the width of the PVC profile.Structural section width usually depends on the number of cameras.This option for a 3-chamber profile is approximately 57 - 63 mm, for a 5-chamber - up to 70 millimeters, and sometimes - and up to 120 millimeters.
It is also important to know what thickness profiles can be set without losing quality.It's simple - the more constructive section width, the thicker you can insert a glass with a large number of cameras.Consequently, the greater the width of the window profile, the finished plastic window will be warmer.
fittings to windows
Clients interested in the choice of windows, first of all, especially of glass and profiles.However, under the influence of mechanical loads and weight is precisely accessories.A typical window for its service life will be opened, closed at least 50 thousand times, so the quality will depend on hardware reliability, durability and quality of the use of windows.
Window accessories is a complex locking mechanism.This brackets, hinges, rods, connectors and other elements (more than a hundred pieces), providing a snug fit to the sash frame, the opening and closing of the plastic windows in different modes.At a low price it is usually offered furniture, which is made of soft metal, and sometimes - in part of plastic.
windows that are collected using a hardware all the time have to be adjusted.A couple of years they will need complete replacement.So choose working arrangements, which are made of durable metal.The hardware is not accepted individually selected from the window, because basic hardware is already installed on it.
But apart from a standard kit that allows the window to be opened and closed, it is possible to arrange a plurality of sub options: stop turning, ensures fixing the sash windows in the extreme open position;sash tilt limiter, which provides a safe ventilation;Slit vent, which allows a few centimeters to lift the box;lifter, allowing to lift sagging sash, thus relieving loop.
can also pick up a few options for ventilation, for instance, micro-ventilation, which allows windows do not fog up, ventilate the room at the same time and are not afraid of drafts.There are several types of micro-ventilation, when you open the flap about 3 - 55 mm.
lion's share of the window opening will take it is glazed, so you need to really get serious about his choice, if you are interested in the quality of plastic windows.Glass unit represents a block of several panes, between which there are sealed chambers.Double glazing on a par with the profile is responsible for the soundproofing and thermal insulation of the window.Poor-quality double-glazed windows to reduce "no" to all the advantages of the best frame.
When choosing glass should pay attention to the following points:
- According to existing regulations, the thickness of the glass should not be less than 4 millimeters.Often, however, in recent years, you can "bump" on the windows with double glazing, in which instead of the "quartet" set "troika".
- to good thermal insulation is necessary to use a multi-chambered plastic windows - at least two-chamber.Triple-pane windows will save you from excessive street noise, and help keep the heat in the home.This design consists of three panes, between which the air chambers.
- Triplex is a glass, which consists of a pair of layers and laminated with a special film, which is located between the glass and provides security, since no physical impact shatters.In addition, an increased level of triplex characterized insulation and does not transmit ultraviolet light.
- ideal option for those owners who are looking for windows for money and want to increase the insulation in your home, would be the order of glass, which are manufactured using energy-efficient i-glasses.On it to conserve heat treated with a coating that does not transmit infrared light and allows in the summer to maintain the room cool, and the winter cold - not to let the heat out.Even with such a double glass pane glass will act as heat saving, because the special coating reflects the heat inside, not allowing it to go through the window.
- To protect against sunlight, you can buy a glass with a mirror coating that is applied by spraying a metal oxide.Another method of protection from the sun is the use of colored glasses.In addition, you can put glazed stained glass.
If you combine glazing and profile can be obtained here are the options:
- chamber profile and double glass pane.This is quite an economical option, which is used for non-residential premises, and windows that look out to the loggia, or glassed-in balcony.
- chamber profile with triple glazing.In this case, you get a plastic box for money with excellent thermal insulation and noise protection, which are usually installed, if you live in a well-heated house.
- Five-chamber profile with triple glazing.This solution is able to provide you maximum protection from cold weather and noise.This option is ideal for those homes, which are located close to the tram and railway tracks, as well as the busy road.
windows from different manufacturers differ in color seals, which are laid on both sides of the edge of the glass, as well as at the junction between the sash and frame.Black seal perfectly emphasizes the whiteness of the profile.Besides black seal will last you much longer gray or white, which are also present in different profile systems.
White and gray seal loses its elasticity after 2-4 years and become dirty, especially if your home is located near the highway passing.Wash the seal from the city smog does not work, but on the black compactor these contaminants just not visible.
Seals made of special rubber, rubber or silicone rezinoplastika.Their characteristics are one of the main factors that provide the insulating properties of the plastic window.Most effectively provides a seal, sound and heat insulation seal designs, which is made on the basis of EPDM polymers and rolled-in PVC.
quality installation of plastic windows
course, quality PVC windows will depend not only on the characteristics of the profile, glass and furniture, as well as from the competent assembly.Many problems that occur with plastic windows, are explained by their improper installation.It is therefore important to know how to check the quality of plastic windows after installation.
The main condition of success is in the correct metering of windows and drawing a sketch of the future glazing.It may seem at first glance that measure the height and width of the window opening is quite simple, but here without the skills, abilities and experience can not get enough.
Custom windows for the wrong designs may not be appropriate in the doorway, and then they will need to adapt.Before installing plastic window check that the imported product openings, as you can in case of error gager remain open apertures.
window must be securely fastened, because his weight up to 100 kg.Fasteners are the most vulnerable point in the process of installation.We warn you against fraud, for example, that for the installation of clamshell box with a partition takes at least 14 fasteners - is, as a rule, the anchor plate.Consequences of savings in this case amount to subsidence window sashes warp and the emergence of micro-cracks in the mounting seams.
If you are interested in how to determine the quality of plastic windows after installation, you should check the density of closing the window.To do this, you can not wait for a change in wind direction or frost.It is easy to take a sheet of newspaper, put it between the window and the frame and close with the help of accessories.Then you need to try to gently pull the jammed sheet.He had to stretch hard.
Repeat this operation we recommend on the perimeter.If one places a sheet can not be withdrawn at all, in others - it is possible to get without any effort, and the seal has no defects, the required adjustment of the fittings.In addition, when you turn the knobs, you should not feel extra freedom of movement, should, on the contrary, present some effort.
should also check and vertical mounting of the window construction.When you open the window should not move independently in the direction of opening.If you found this defect, it is necessary to think about reinstalling.Remember to check for end caps of the thresholds and window sills.Sometimes they simply forget about, or they are shorter than necessary.
When installing plastic window must always comply with regulatory distance between the frame and the wall - 1.5-5 centimeters.This arrangement requires for proper assembly seam which consists of foam, sealing tapes and sealants.This joint serves as a layer between the "warm" cold frame and the wall.If good quality plastic window set against a wall, then in the winter you can find out what the freezing window.
main element assembly seam is a special foam hardens.Along with household foams Sales of the brand are presented, which are designed specifically for Windows.They are divided into "winter" and "summer."Pay attention to the features of their use.When completing the installation joints are not allowed void and prohibited from street-side to cut the cured foam.After all, in which case it loses its protective "crust" and open the pores of the hygroscopic, which accumulates over time moisture freezing in winter and destroying foam.
Even foam which has a "crust", needs to be protected.Windows that are installed only on the foam, in a few years will show signs of aging.Frames in the doorway, "stir", causing airflow through microcracks between the room and the street.As a result, an area of high humidity, and the frames on the slopes, there is fungus and mildew.To protect the foam made use of sealing tape or sealants.
As we know, plastic is able to expand when the temperature increases, for example, in the sun.These changes are minor, but still sent to the mounting seams.To protect them from deformation in the opening frame to give extra stability, it is necessary to set special support pads - of antiseptic-impregnated wood or plastic.Lack pad helps violation sealing assembly seam.
by the structure and slopes should not present traces of foam.If foam is present, it means that the protective film has been removed before, that is, until the installation window.You can remove the mounting foam after drying using fine sandpaper to the future polishing a special paste.However, if the material is rough and not smooth, then this procedure will not work, because a difference occurs in the surface structure.
And finally, before you decide which window better quality, remember: quality plastic window can not be cheap!Saving money today, you will encounter in the near future with many challenges - low noise isolation, poor ventilation, provoking fogging windows, condensation and soggy wall surfaces near the plastic window, a low window frames color retention and yellowing, warping, and the complexity of the window in the opening-closing.
