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 the 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.

Soundwork
Of course, plastic window systems have resistance to penetration of sound more than aluminum.Cost
Plastic profiles are much cheaper than aluminum, which attracts the average buyer and there is a pledge of their popularity.
