The average home loses 10% of its heat through windows and doors. Good, energy-efficient glazing reduces heat loss, retains home warmth, and reduces heating costs.
A lot depends on the chosen double-glazed unit. It is important to say that energy efficiency is a multi-faceted concept that depends on good installation, quality sealants, tightness of the sash, number of air chambers, content of air chambers, but most importantly - quality glass indicators.
The principle of creating an energy-saving insulating glass unit involves applying a special coating to the surface of ordinary window glass using a magnetic sputtering technique. An energy-saving insulating glass unit made using this technology functions as a kind of thermal valve - it allows heat from the outside into your home and reflects it like a mirror, preventing it from escaping and thus saving both heat and your budget.
Using energy-efficient double-glazed windows allows:
Save on heating in winter and air conditioning in summer;
Protect against ultraviolet radiation, which has a positive effect on the health of your eyes and helps prevent fading of interior objects, walls, paintings, and wallpaper;
Thanks to its coating, the glass allows sunlight to pass through, reflecting short-wave radiation from the outside in winter, and reflecting long-wave thermal radiation inward. In summer, the opposite happens: the window reflects the long-wave thermal radiation from the street, preventing the room from overheating in summer and staying cool in winter. As a result, it retains 60% of the heat compared to the 30% retained by regular double-glazed windows.
The temperature on the glass surface is higher than on the surface of regular glass, which prevents condensation. The gap between the two glass walls in an effective double glazing unit is filled with an inert, non-toxic gas. This gas has a higher density than air, so it effectively reduces heat loss. Argon is the most commonly used gas in glass units because it is extremely economical, colorless, and does not react with other gases.
When installing a single-chamber energy-saving glass unit instead of a double-chamber one with regular glass, you save money both during the ordering process and during the window's operation. The energy savings amount to 35% per year, and the windows will pay for themselves in approximately one year.
By using energy-efficient double-glazed windows, you contribute to the conservation of natural resources and, therefore, the improvement of the environment.
