What is the difference in plastic windows. The use of metal-plastic windows. Glass accessories: how to make the optimal choice

For the manufacture of plastic windows, special material - PVC or polyvinyl chloride is used. In their appearance, such products resemble ordinary wooden windows, nevertheless their design is more complex, as it includes several layers separated from each other, hermetically mounted in a special frame. Due to this, if compared with conventional windows, double-glazed windows have better sound and thermal insulation.

The windows of polyvinyl chloride are usually installed in homes, apartments or cottages and are not suitable for installation in industrial premises. It is explained by the fact that such structures do not differ particularly long service life (no more than 10-20 years) and all the more at all are not suitable for use in extreme. But simple care for products and quite reasonable value make them specially sought after consumers.

Metal-plastic windows

Metal plastic windows are largely similar in its appearance with plastic structures and have practically the same pluses. But, from the point of view of constructive features, there are still certain differences between them. Such products are equipped with an additional metal frame. The latter is embedded in profile and is the main component of the entire design. In appearance, it is no different, which is why there is a certain similarity between plastic and metal-plastic windows. But this is only at first glance - metal-plastic structures have higher strength and resistance to negative environmental impacts. If you are marked professional, then we can say the following: "Such constructions are reinforced with galvanized profile."

Metal-plastic windows are ideal for use even in the most extreme conditions, they have a long service life (more than 50 years), and most importantly - they can be given absolutely any form: round, stroke, arched, etc. The cost of such products is much higher than that of the same plastic windows, but also quality at height.

What exactly choose - metal-plastic windows or a design of PVC - to solve only you. Here it is necessary to take into account the most different factors: features of installation, operating conditions, the necessary characteristics of the product, appearance and, of course, financial capabilities.

Every day the construction service market is filled with various innovative developments. Starting with professional tools and ending with structures and fittings. For example, a couple of dozen years ago, each of us has installed standard wooden windows, then the era of plastic windows came, and now it's already the bullshit of the past. Currently, the technology of frameless glazing is a great success, pusing the classical technology for mounting frames and vertical racks. Plastic windows replaced with metal-plastic, which are distinguished by increased wear resistance and reliability.

Differences of metal-plastic windows from plastic

At first glance, not everyone can distinguish metal-plastic windows from plastic, externally, they are identical, since plastic is used in those and those outside. But their design features are essentially modified. In the process of producing metal-plastic windows, reinforcement of a metal frame for PVC profile is used. As a result, even under the scorching sunny rays, the frame and fittings are not deformed.

If you analyze and compare metal plastic windows with plastic, then general functional properties can be distinguished - it is excellent sound and noise insulation, as well as anti-svliness. But, there is an indisputable advantage at the metal-plastic profile, if you wished to glazing the balcony with the windows in the form of an arch or some other shape, then the plastic windows do not fit you, as they are produced only in a simple rectangular form.

Choosing metal-plastic windows

It is important to consider that the metal-plastic profile is much more expensive than plastic, but the quality is never cheap. Among the leaders in the field of windows manufactured, European Rehau and VEKA companies can be distinguished, they are not functioning in the construction market and have positive reviews among potential consumers.

The first where to start it is to pay special attention to the choice of the thickness and material of the reinforced frame. After all, the level of corrosion exposure depends on it. The most acceptable thickness of 1.5 mm, the material is galvanized steel. Also on the construction services market there is a cheaper option of the frame, which is made of black metal. It has an indisputable minus - it can quickly start rust, caused traces in the area of \u200b\u200bdrainage holes.

Choosing a metal-plastic window, no matter what does not differ from the usual plastic, here everyone chooses what he wants, the number of cameras, double-glazed, accessories, the thickness of the profile, etc. But it is important to consider that the classic plastic profile is preferably selected for installation in apartments, cottages, country houses. Metal-plastic windows are installed mainly, indoors where high dynamic loads are common, sharp climate drops, squall winds, and the like.

How manufacturers reduce the cost of the profile of metal-plastic windows

Of course, not all manufacturers firms seek to reduce the cost of the profile due to poor-quality fittings and reduce the thickness of the profile, but there are such. In connection with which consider both the market value when ordering the installation of metal-plastic windows, because the decrease in the wall thickness leads to a decrease in strength and durability. Also choose a profile with a closed metal reinforcement, it perfectly withstands the sharp drops of dynamic loads.

Do not forget that even the best and expensive windows can be spoiled, unprofessional installation. Choose only verified firms on the installation of windows, because their durability directly depends on the masters.

Today there is a very acute problem of energy saving, and therefore the replacement is replaced or installing new windows, which will reduce the weight loss of your housing, being more sealed compared to traditional wooden. It is desirable that they have beauty, ease of use, practicality and quality. Today, many firms offer windows of different designs, material manufacturing, purpose and price.

A good plastic window should be protected from cold and noise, not only beautiful, but also reliable. And, unambiguous, the window must serve for a long time.

So what differ plastic windows with each other and from other windows?

Difference from each other

Device plastic

The window consists of:

frames;
double-glazed windows;
accessories;
windowsill;
waterfronts.

Frame

In the conditions of the South Coast climate, with sufficiently strong seasonal winds, especially for multi-storey houses, the use of windows with a thickness of less than 60 mm is not recommended.

The frame is 20-30% of the window area and is made of plastic profile reinforced with metal. The profile can be three- and five-chamber with different configuration and patterns of cameras. In this case, its width is either 58 mm, or 70 mm (for the northern regions of the continent may be thicker). The chambers are formed inside the profile by partitions so that air rollers are placed around the perimeter, which helps to achieve high sound and thermal insulation, and affect the strength and rigidity of the frames.

In addition, frame profiles are distinguished by the thickness of their walls, material and reinforcement technology. The profile can be reinforced by all 4 sides of the window or only by 3rd.

In low-cost systems for plastic saving, sometimes reduce the thickness of the chambers of the chambers, which leads to a decrease in strength and frost resistance. The outer surface of the frames can be a glossy or matte.

Glass windows

Double-glazed windows are a structure with a thickness of 34 mm or 44 mm, consisting of several glass cloth connected along the edge, between which the space is filled with rarefied air or argon (which does not really affect their thermal conductivity). They are single, two- and three-chamber with a thickness of chambers from 6 to 16 mm and are differentiated depending on the severity of the climate. Various the quality and thickness of the glass in the package (from 4 to 7 mm), as well as their properties: conventional glass, energy-saving to-glass or and-glass (with spraying on their surface of silver ions). For the best sound insulation and for a different climatic zone, the thickness of the glass in the package is combined.

Furnitura

The picture shows: handles, lifting blocker, microwing function, lock adjustable pin, built-in retainer, press the bottom hinge of the sash.

Fittings are locks, loops, handles, that is, all those mechanical elements, thanks to which the windows have the opportunity to open and close and on which the convenience of use mainly depends on. They are distinguished by resistance to wear, loads and safety. The window in the direction of opening can be swivel or folded with the possibility of slotted ventilation or without it. And the systems allow you to install: mesh mesh, blinds, ventilation systems, etc. Recently, when making plastic windows began to establish climate control, which smoothly adjusts the flow of fresh air without dirt and dust. The loops of cheap fittings are no possibility of their adjustment, which can entail unregulated gaps, which will lead to an additional loss of thermal energy.

Window sills

The window sills are a segment of a special plastic profile with special plugs. The main requirement for them is their strength, which depends on the thickness of the walls and the number of internal partitions. Their appearance depends on the manufacturing material.

Aluminum

Windows, the frames of which are made of aluminum alloy (and not from pure aluminum, as someone may think), are widely destination windows. Aluminum profile is similar to plastic: It has internal chambers, places for mounting double-glazed windows and seals.

Differences from plastic

Thermal conductivity of Ram.

Aluminum windows have a higher cost compared to others, but they have durability, high thermal conductivity, easily clean and can have any complex shape.

The ability to transmit heat in aluminum is much larger than that of polyvinyl chloride, therefore, the frames made from aluminum should have more cameras and special insulating fillers. Aluminum profiles are "cold" and "warm." "Cold" are profiles with a small number of cameras (about two), designed for mounting in places where there is no need for thermal insulation (indoors, balconies, technical buildings). The "warm" cameras are a lot and successfully compete with plastic. In addition, in aluminum profiles, in order to avoid the appearance of the heat bridge, the wall contour from the special material of the polyamide is inserted - they are equipped with a thermal survey.

Relness Ram.

Plastic is softer aluminum, and to increase the rigidity and strength of the frames of them they are reinforced by metal, eliminating this difference.

Durability

It is clear that the metal saves a neat appearance longer. Aluminum windows profiles remain attractive almost twice as long as the plastic. In addition, with damage to aluminum frames, the profile can be restored or replaced, which cannot be done with PVC frames. But the scratches on the metal are visible more clearly, and it is almost impossible to eliminate or disguise them.

When fire, an aluminum window is resistant to high temperatures, and plastic is not.

Only from aluminum you can make windows of very large sizes. In addition, aluminum is absolutely fireproof.

Svetrability

Due to greater strength of aluminum windows, compared with plastic, they have thin frames, which increases the area of \u200b\u200bthe glass package, so there will be more light in the room.

Ecology

Plastic profiles contain chlorine derived from oil, which when burning the exhaust windows is converted into dioxins, and aluminum alloys are easily recycled.

Modern windows manufacturers offer customers a large range of translucent structures with different characteristics, operating parameters and appearance features. Buyers are often lost in a variety of options, not knowing what criteria to compare the models, assess their advantages and disadvantages. The most popular today are windows from, but not all customers know that there are two categories of these structures, each of which has its own characteristics, advantages and disadvantages.

What is the difference in plastic and metal-plastic windows

Conventional plastic windows are structures, frames and sash which are made of PVC profile without adding additional reinforcing elements. This type of windows has average strength and durability, but profitable for the budget due to the simplicity of manufacture and relatively low cost of the finished product.

Metal-plastic windows are not different from simple PVC products, however, if you see such a profile in the context, the eyes will open the presence of an important additional part - the internal metal liner. The inner metal frame increases the strength and reliability of the structure. It is made of steel with an anti-corrosion coating, placed inside the chambers of the frame and sash around the perimeter. The enhancing frame is closed - with a cross section form in the form of a quadrilateral or unlocked - with a cross section, resembling the outline of letters r or P. The thickness of the steel plate, as a rule, is 1.2-1.5 mm and depends on which load should withstand the design . The main requirements for the quality of the material and the method of installation of the framework are set forth in Guest 30674-99, which is valid throughout the Russian Federation.

Advantages and disadvantages of plastic and metal-plastic windows

Plastic windows

The advantages of plastic windows include their low cost (compared to reinforced counterparts) and low weight. These window systems are available to most consumers and perform their functions well during a certain period. The small weight of the windows from the unarmed profile allows them to be installed on the balconies, producing minimal amplification of the parapet.

However, as mentioned above, plastic windows without a reinforcing metal frame are less durable. Most manufacturers are guaranteed 20-30 years of workability of such structures when using them under normal conditions. The profile constantly turns out to be a large load: in addition to its own weight, it holds heavy glass, which can weigh up to 80 kg.

It is worth noting that even the highest quality plastic can be deformed from sharp temperature fluctuations and long exposure to its sunlight. For this reason, the service life of plastic windows in the regions with an unstable or hot climate will be less.

Metal-plastic windows

Reinforcement gives PVC windows additional strength, extending their lives and increasing the ability to withstand diverse loads. Metal-plastic windows are not afraid of a strong wind, tests of temperature drops, their sash rarely sag in the weight of the glass and work even in super-intensive mode. The average service life of metal-plastic windows is 40-50 years. Metallic gain profile allows manufacturers to create structures of various shapes and not worry about their possible deformation.

There are metal-plastic windows and individual deficiencies that should be considered when purchasing:

The appearance of "cold bridges". Metal elements compared to plastic have greater thermal conductivity and reduce the thermal insulation characteristics of the entire structure. To minimize the influence of this factor, the manufacturers have come up with the following: Reduce the area of \u200b\u200bcontact of the carcass with plastic, installing inside vertical ribs that hold the metal in the desired position.

High price. Any windows of the reinforced profile (naturally, we are talking about quality products) cost more than similar models from ordinary plastic. Galvanized steel is quite expensive material, and therefore the price of structures increases in proportion to the amount of metal used.

When choosing windows with reinforcement, it is necessary to take into account that together with the increase in the strength of the window system, the internal metal framework significantly increases its mass. Accordingly, metal-plastic windows are noticeably heavier than conventional plastic analogues. Due to gravity, such windows are hardly suitable for installation in buildings with dilapidated walls, and before) Parapet must be reinforced.

Scope of application

After studying the main characteristics, as well as weak and strengths of plastic and metal-plastic windows, you can start the choice of the most suitable option for your room. Each case is individual, however, there are a number of general recommendations of specialists to whom it is worth listening to:

For premises on the upper floors of "height", as well as for installation in homes located in the open space (with the maximum probability of regular exposure to strong winds), it is worth choosing metal-plastic windows.
Apartments in standard multi-storey buildings of large cities located in the middle lane of Russia (and other regions with temperate climates) can be equipped with simple plastic windows.
Conventional plastic windows - a decent option for buyers with a limited budget.
For installation in buildings with large window openings or it is recommended to use exclusively metal-plastic windows.
The windows designed by individual projects, the design of non-standard form, original models for design interiors are made mainly from the PVC profile with reinforcement.
The glazing of structures that are not able to withstand a significant load, such as balconies with a fragile fence, should be performed by products from a plastic profile without steel liner - they have a smaller weight and minimize the likelihood of its damage or destruction.

A good plastic window should be protected from cold and noise, not only beautiful, but also reliable. And, unambiguous, the window must serve for a long time.
