Energy-saving Glass.

Today I will talk about energy-saving glass, which makes the house warmer and more comfortable.
In the last decade, conversations about energy saving and heat conservation have never been more relevant. For the sake of their own budget or to save the environment, people are increasingly trying to save on heating and spend less electricity.A clear proof of this is the idea of the passive house, that has come from Europe.
Plastic windows account for most of the heat loss - up to 40%. And this figure is relevant not only for passive houses, but also for ordinary houses.

What is Energy-saving Glass?

There are two types of energy-saving glass - k-glass and i-glass. Hard-coated K-glass is considered an obsolete technology. It is rarely used in homes, since the manufacturing technology of i-glass is much simpler.
Solid spraying is applied to hot float glass. Through a chemical reaction, a thin layer of transparent metal oxides with high electrical conductivity appears on the glass.
After this, the glass can reflect long heat waves or, more simply, leave heat where there is initially more of it. In the summer - outside the house, and in the winter, respectively, in the house.

Soft-coated glass is used by almost all window manufacturers. Unlike its “predecessor,” i-glass is installed by spraying inside, since contact with air reduces its quality. Energy-saving i-glass is produced by vacuum deposition. Three or more layers of special metal oxides are applied to the glass. To facilitate production, a silver ion coating is applied to the cold glass.

Energy-saving glass and its advantages.

I have mentioned the advantages of energy-saving glass many times. After all, energy-saving, or multifunctional glass, is a universal option and is suitable for almost any room. Energy-saving glass retains 28% more heat than regular glass in winter. So, at a temperature outside the window of -14,8 degrees, the temperature of ordinary glass will not exceed 41 degrees, and energy-saving glass 6,8 degrees.
At first look, it is an insignificant difference. But this indicator significantly increases the temperature difference between the glass surface and the room. Along with it, the likelihood of condensation on the windows also increases.

This difference also affects the thermal comfort in the room. Moreover, heat preservation in this case is not the only important indicator. it is worth thinking about the sun protection ability of glass in the Summer. On average, energy-saving glass transmits 10% less sunlight than regular glass. This helps to keep the room cooler longer and saves the apartment from the heat in the summer.

Energy-saving glass not only maintains a comfortable temperature in the house, but also allows you to save on heating and air conditioning.
When choosing a window, pay attention to this and calculate how quickly an energy-saving window will pay for itself.
