Double glazing is a better system than double window: it means long-term savings, reduces condensation in the environment, minimizes outdoor noise pollution and is practically unbreakable. But those are not your only advantages.

Before entering the subject, it is necessary to clarify -because there is some confusion about it- that one thing is a double-glazed window and another, a double-glazed window. Both systems serve to save energy and money while achieving thermal and acoustic insulation. But its effectiveness, in all aspects, is different.

By the double window, it is understood the installation of another window on the inside or outside of the existing one. Effectively some term and acoustic insulation are achieved, but it is not the best system. It also has the disadvantage that in cold weather a lot of condensation is generated between the windows that make continuous cleaning necessary.

Double glazed window

The Double Glazing is basically composed of two sheets of glass separated by a chamber of dehydrated air or gas. It is a better system than the double window, although there are tastes for everyone. In the quality and the result that can be obtained from double glazing insulation, the two factors that make up the system influence: the glass and the air chamber.

The crystal factor

The thickness of the crystals influences positively or negatively as long as it is larger or smaller. The quality of the glass also influences. There is a wide range of crystals that improve the quality of those considered normal: those of reinforced glass; those that control the amount of solar energy that enters the interior to a greater extent than a normal crystal; the specials that, despite being thinner, are more resistant; those that increase the light, etc. Currently, self-cleaning crystals are developed; others that darken or lighten according to the amount of light they receive, etc. The field of research is growing.

The air chamber

The other factor - the thickness of the air chamber between the two sheets - influences greater or lesser insulation, the greater or lesser its thickness. The optimum is 16 millimeters, although this depends on many variables.

Combination of glass and air

In the combinations of double glazing figures that we will find, the first and the last digit correspond to the thickness of the glass and the middle one to the thickness of the camera between the crystals. For example, in combination 4-16-4, the first and last digits (4) indicate the thickness of the crystal in millimeters; the middle one (16) indicates the thickness of the air chamber also in millimeters.

There are many combinations. The greater the one and the other, the better the insulating power there will be, although, logically, the price of the windows varies in the same proportion.

Advantages of double glazed windows

The installation of double insulated windows has a number of advantages that we list.

Durable goods

To date, the change of the old windows by others with double insulation is not cheap. However, it must be borne in mind that windows are elements that, once installed, will last a long time, so it is very important to know how to choose the best combination of glazing and profile, in order to enjoy optimal benefits.

Energy efficiency

We must also consider the savings that this will bring us in the long term, which will more than compensate for the cost of the investment. Undoubtedly, if a more efficient thermal insulation system is installed, the house is better insulated, will save energy and, consequently, also money.

In summer, the cost of air conditioning will be lower because when entering less heat from outside you will need fewer degrees and less operating time and, for the same reason, in winter the heating expense will be reduced because the heat is not lost to the outside. In the long run, the investment made will be economically justified, and in terms of comfort and comfort conditions, it will be as of its installation.

Humidity reduction

Another positive effect of double glazing is the reduction of condensation, which is the conversion of water vapor into droplets. The humidity can give a cooler thermal sensation to the room, which forces the home temperature to rise. However, the air between the two layers of glass, in addition to hermetic sealing, prevents condensation from accumulating by blocking moisture in cold climates.

Acoustic isolation

The acoustic insulation that is achieved with double-glazed windows is another positive factor that must be taken into account. There is a lot of concern about atmospheric pollution and not so much about the acoustic contamination that, according to medical studies, greatly influences the health of people. In areas where the noise generated by road traffic, the operation of machines, etc., is considerable, it is very useful and convenient to install systems, such as double glazing, to reduce as much as possible this inconvenience. The greater comfort that is obtained will contribute to a better quality of life.

Practically unbreakable

Another advantage of double-glazed windows is that they are more difficult to break than single- glazed windows, making them safer, especially if there are children in the house. Also, furniture, carpets, paintings, etc. they suffer less damage from the entry of light and the heat of the sun that can discolor and dry them. In addition, if we join the double glazing to a good insulating profile, we will achieve an optimum level of thermal insulation for our homes.
