What kind of windows to install in 2017? We know...

The glazed balcony has always been and will be a more perfect design. Thanks to glazing, we have an order of magnitude to increase the level of protection of the balcony from any weather problems, dust and noise, and also keep the heat in the house. And this is not to mention all the benefits of a separate private room, which can be arranged on your own. The only thing that remains open is the choice of materials for glazing. Plastic or aluminum windows - which are better? Each individual owner of a balcony or loggia solves this problem individually. The most important thing is to determine the purpose and understand why you need this or that kind of glazing.

Plastic and aluminum systems

When the question arises, which balconies are better - plastic or aluminum, one immediately has a desire to learn more about the properties of each of these materials.

Plastic windows consist of thick-walled profiles, inside are divided into cameras. This allows better storage of heat, as well as increase the rigidity of the profiles. Insulating glass units are inserted in the frames, which can also have several chambers. The more cameras, the better the thermal protection and sound insulation of the window, but the greater its weight. Ecological compatibility of plastic systems is proved by practice.

Aluminum windows are made of lightweight aluminum profiles. There is a technology of manufacturing very large in size designs, in contrast to plastic ones. Inside the aluminum frames are inserted ordinary glass. Also there are warm frames, the construction of which is multilayered.

What are the design of windows?

Which is better: aluminum loggia or plastic? The answer can be ambiguous. Much depends on the size of the balcony and the design of the window system. Let's look at what designs are by the type of their opening.

Sliding systems

Frames have a design that allows the flaps to move to the sides, overlapping each other. This saves space on the balcony, and windows acquire a non-standard solution. Such systems completely cope with their task of protecting the balcony from precipitation and wind. For a narrow balcony, this system is ideal. The disadvantage is that the lower guide, along which the flaps move, is not sufficiently protected from precipitation. This can cause the aluminum windows to freeze in winter. When using plastic frames, this defect is canceled.

Rotary systems

This is the simplest design, in which the doors are opened by turning them. It is easy to look after such windows. If the balcony is narrow, then it may simply not have enough room to fully open the sash. Depending on the rotary axis, the flaps can be rotated in a vertical plane or in a horizontal plane. In some cases, the opening of the flaps can be made outside the balcony.

Turning and tilting systems

The most popular system that allows you to open windows, and recline them for ventilation, when full opening is not required. Which frames are better: plastic or aluminum for this design? It is more convenient to work with plastic frames, since aluminum systems may not have a swing-and-tilt mechanism.

Folding systems

The sashes in such windows recline into the room to ensure ventilation. Often they are used as windows of various sizes.

Deaf Systems

These are the simplest and most reliable windows that do not open. The disadvantage of deaf systems is the inability to wash them outside. They are usually installed in private homes, in porches, in industrial enterprises. When installed on the balcony, they fill the side walls. If you glaze the loggia with such windows, then for the subsequent washing it will be necessary to take out the double-glazed window, wash it, and then insert it back, which is not very convenient.

Features, advantages and disadvantages of windows

To determine for yourself which windows are better - plastic or aluminum, you should study their basic parameters. Let's make a comparison and consider the differences.

Advantages of aluminum frames

  1. Aluminum profiles are very light, which is very important when the frames are mounted directly on the parapet. In addition, the frames are glazed with ordinary sheet glass, having a thickness of 3-5 mm, which also facilitates the construction of windows.
  2. Aluminum is very durable, so the windows have almost no end-of-life.
  3. Frames are not exposed to corrosion, do not decay, have a slight thermal expansion.
  4. It is possible to make windows of large sizes and different shapes.
  5. Full fire safety.
  6. The widest color range.
  7. Low cost of systems, so this glazing will be cheaper.

If you are not sure, the better to glaze the balcony, aluminum or plastic, take a closer look at the shortcomings of aluminum.

Disadvantages of aluminum structures

  1. This is a cold profile. It heats very quickly and quickly cools. In winter, the heat is practically not kept. In summer, on the contrary, it quickly takes on the solar heat, and then redirects it to the room.
  2. If the balcony is very high, sliding frames larger in size may deform under the influence of wind loads.
  3. Low degree of soundproofing of the balcony from the street.
