Choose plastic windows Boston

High-quality HOW TO REPLACE WINDOW GLASS IN WOODEN FRAME   Boston translucent structures for many years protect the room from the scorching sun, cold and wind, provide optimal humidity in the room, perform protective and other functions. It is important to know how to choose the right plastic windows for an apartment in order  to understand which characteristics you need and which ones are not worth paying for.

Plastic windows Boston

Compared to old-style structures in wooden frames, PVC windows win in everything:

• durability;

• aesthetics;

• tightness;

• ease of use;

• parameters of thermal protection and sound insulation;

• no need for care and insulation.

 Modern wooden windows are equipped with durable "warm" double-glazed windows, they look aesthetically pleasing, but have a couple of significant drawbacks: high price and the need to update the coating.

Why plastic windows are better

The hermetic design prevents heat loss, which is especially important in houses with insufficient heating system capacity and apartments in which heating devices are equipped with meters and temperature controllers.

Closed PVC windows do not let in street noise at all. You will be able to sleep peacefully even in apartments overlooking major highways or busy streets.

PVC window sashes can be hinged and swivel, open in several planes at once, often equipped with the so-called "ventilation mode".

Wooden frames need periodic updating of the paintwork, maintenance of PVC windows is not required. And plastic windows are easier to clean than wooden ones.

Disadvantages and the issue of environmental friendliness

Plastic window frames have one significant drawback - non-repairability. Scratches, scuffs and other surface damage cannot be repaired on plastic. However, plastic is much harder than wood, and it is more difficult to scratch it during operation.

Many opponents of PVC windows argue that wood is better for translucent structures, as it "breathes". Most likely, these people do not know about the existence of exprof Aero plastic windows , which allow air to pass through when the leaves are closed, providing a normal indoor climate without drafts, freezing and condensation.

Plastic can hardly be called an environmentally friendly material, but modern manufacturers have tried to make it as safe as possible for humans. In its manufacture today, components that are harmful to health are not used.

Wooden frames, as an alternative, also cannot be called a model of environmental friendliness. In their production, glues, impregnations, varnishes and paints are used, often with a dubious composition.

Construction of plastic windows

Unlike wooden windows that were installed in apartments in the last century, plastic counterparts have a more complex design.

What is a plastic window made of?

Profile

 is the main element of the window block. Its purpose is to combine other components into a whole structure.

The ability of the window to withstand operational loads depends on the quality of the profile:

• opening and closing of doors;

• the weight of the double-glazed window;

• wind;

• precipitation;

• high and low temperatures;

• exposure to ultraviolet.

The properties of the double- glazed window determine the heat and sound insulation of the window block, as well as the degree of natural light in the room.

Fittings play an important role in the usability and durability of the translucent structure. Details such as constipation, clamp, scissors, handle, bar are responsible for the possibility of opening the sashes in different ways.

The window sill and slopes do not belong to the structural elements of the window block and are decorative details.

Design features of Exprof windows

Proper plastic windows should be equipped with a ventilation mechanism to ensure a constant supply of fresh air into the room, an optimal level of humidity and a healthy microclimate. The frame of exprof Aero breathable windows has a built-in ventilation chamber designed to let in and heat air from the outside while maintaining tightness, heat and noise insulation of the structure.

The main characteristics of plastic windows

To know which plastic windows to choose, determine the important characteristics of each structural element. Choosing a profile for PVC windows and double-glazed windows in accordance with the climatic features of the living area, the location of the house and apartment will help to acquire a high-quality and warm design that will last for decades. Consider the types of components in more detail.

Number of air chambers in windows

Chambers - voids in the elements of the plastic structure (profile and double-glazed windows). How many cameras should be in a quality window? The answer to this question depends on the climate of the region where you live and the location of the apartment.

The more chambers, as well as the distance between their walls, the higher the performance of noise and heat insulation. Two-chamber profiles are intended mainly for cold glazing, unsuitable for windows in heated rooms due to low thermal insulation.

For an apartment window in a big city, it makes sense to consider at least a three-chamber profile. For rooms located on high floors, apartments with a poorly functioning heating system and rooms facing highways and multi-lane avenues, five- and six-chamber designs are suitable.

Window profile width

The wider the profile section (the distance between the outdoor and indoor surfaces), the warmer and quieter the translucent structure will be. In a wider profile, you can put a double-glazed window with better thermal insulation and noise reduction characteristics.

The most common window profile width levels in Russia are 60 (from 58 to 62 mm) and 70 (from 70 to 76 mm). For most regions of our country, the second option is preferable.

The system width of exprof profiles is 58, 60 or 70 mm, depending on the type of window and the number of chambers. The manufacturer's profile systems allow installing a double-glazed window up to 36 mm thick in a 58 mm profile, and up to 44 mm thick in a 70 mm one.

The mounting thickness of the exprof Aero breathable window frame is 101 mm. This is the optimal size to ensure a high level of noise and heat insulation even for three-chamber profiles, as well as high-quality ventilation with closed doors.

Reinforcing insert

Reinforced windows are stronger and more durable. Reinforcement is an essential component of a high-quality translucent structure. It is necessary so that the windows can resist wind loads, and also do not deform due to thermal expansion. This is especially true for regions with significant temperature fluctuations throughout the year.

To reinforce the plastic profile, special steel inserts are used, which are mounted directly into the main chamber of the PVC profile. The thickness of steel reinforcement in translucent PVC structures according to GOST should not be less than 1.5 mm.

All profiles in exprof windows are equipped with reinforcing inserts with a thickness of 1.5 to 2 mm and have a protective zinc coating.

double glazing

The main characteristics of the element: the thickness of the double-glazed window, the number of glasses and, accordingly, the chambers between the glasses, the presence of special glasses with heat-protective coating.

A single-chamber double-glazed window is more suitable for regions located in a subtropical and temperate climate, houses located in quiet neighborhoods. A double-glazed window is the best choice with the best heat and sound insulation characteristics (provided that the profile is chosen correctly), a universal option for both city apartments and private houses , it can be used not only in temperate, but also in subarctic climates

Three-chamber double-glazed windows are rarely used in PVC windows, as they are too thick and heavy. Modern technologies make it possible to achieve comparable indicators of thermal and noise protection in simpler ways.

The dimensions of double-glazed windows (glass thickness) also affect the final characteristics of the entire structure. Noise protection will be higher if the outer glass is thicker than the others.

Instead of standard glass, an impact-resistant triplex (two or more layers of glass with a polymer film fixed between them), glass with a multilayer coating that blocks part of the sun's rays can be installed in a double-glazed window.

Intra-profile ventilation of PVC windows

The method of ventilation of the room with closed doors can be implemented in different ways. Some manufacturers install a slotted, folded or overhead ventilation valve in the PVC profile.

Slotted air ducts are a channel with a damper that opens manually or automatically. Seam valves have a more complex device with a shutter that shuts off the flow at a dangerous level of draft. Overhead mechanisms are able to provide the maximum inflow of fresh air, however, they significantly reduce the sound and heat-shielding properties of the window block, therefore they are not widely used.

The exprof Aero windows are equipped with a more modern and efficient supply ventilation system - intra-profile. The solution that provides a continuous supply of fresh heated air through the "maze" of channels inside the profile is a patented development of the company. Such a system eliminates the occurrence of drafts, the penetration of noise and ensures maximum energy efficiency of the window in winter.

What else to look for when choosing plastic windows

We talked about the main parameters of window structures - they should be considered when choosing in the first place. However, there are other characteristics that you should pay attention to in order to choose the best option in terms of thermal protection, sound insulation, durability and ease of use.

accessories

Window fittings are not only a handle, but also all the mechanisms located around the main sash, responsible for its movement, fixing in certain positions.

What accessories for plastic windows are better? Professionals advise choosing only products from well-known manufacturers. Cheap low-quality analogues can quickly become unusable.

It is because of the poor quality of fittings that buyers of PVC windows face the following problems:

• sash jamming;

• opening the window only with effort;

• blowing due to the inability to tightly close the sash;

• creak.

Poor-quality elements can also provoke other problems with the operation of a double-glazed window.

sealant

The seal is responsible for a snug fit of the sash of the window structure and sound insulation, the absence of drafts. To choose a sealant for plastic windows, it is enough to know that high-quality sealing rubber or silicone is elastic, pliable, and odorless. To check the quality, you can compress the media and then release it. A good seal is easily pressed through and quickly returns to its original shape, there are no creases on it.

Well-known manufacturers of high-quality plastic windows, as a rule, complete products with high-quality seals that are resistant to deformation, soft and elastic.

Availability of certificates

There is a separate GOST for each window component (profile, double-glazed window, fittings, components). Manufacturers of materials and products for completing windows must obtain certificates of conformity for their products.

Those. the window manufacturer must have a window conformity certificate, the profile manufacturer must have a certificate of compliance with the requirements of GOST 30673-2013 for the profile, etc.

You should make sure that the seller has a certificate for PVC windows, you can additionally request certificates for the profile and other components of the window block.

Certificate of conformity to GOST 30673-2013 for the profile, test reports for intra-profile ventilation, conclusions of laboratory tests for durability and resistance to climatic influences, as well as other documentation confirming the quality of the exprof profile, you will find in the appropriate section on the website.
