Debunking the myths about energy-efficient insulating glass

Recommendation points

• Myth number 1. The price of energy-saving insulating glass units is not justified by heating savings
• Myth number 2. Double-glazed windows harm indoor plants
• Myth number 3. Double-glazed windows quickly lose their energy-saving properties
• Myth number 4. Energy-saving double-glazed windows have low noise insulation

Energy saving insulating glass units are a relatively new product on the market. For several years, they have been able to gain consumer confidence. The main reason for this phenomenon is the ability of double-glazed windows to reflect heat into the room, which significantly reduces heat loss.

For the production of energy-saving glass units, manufacturers use i-glass, which is significantly superior in properties to k-glass.

However, not everyone has a positive attitude towards energy-saving glass units. Customer surveys have shown that mistrust is based on myth. Some consumers simply do not know all the information about a particular product. In this article we will try to debunk the main common myths.

Myth number 1. The price of energy-saving insulating glass units is not justified by heating savings

The high price of energy-efficient double-glazed windows is a big misconception. The difference in the cost of double-glazed windows and standard windows is about $ 6. To assess the economic benefit, you need to perform a heat engineering calculation of the room, for which you need to know the parameters of the ventilation system, the volume of the room, the resistance to heat transfer, the glazing area, the cost of a calorie.

Experience shows that energy-efficient insulating glass units guarantee 20% to 35% savings on heating.

Myth number 2. Double-glazed windows harm indoor plants

For normal growth and development of plants, it is necessary that they receive a sufficient amount of light. The more, the better. Energy-saving single-chamber double-glazed windows allow about 80% of solar radiation into the room.

It turns out that an energy-saving glass unit stores heat better than usual and is not inferior in light transmission (a single-chamber glass unit transmits 83% of the light, and a two-chamber unit – about 76%). This proves that the owners of energy-efficient glass units guarantee the plants maximum natural light..

In addition, the inner surface of the glass is 5-7 degrees warmer than usual. It heats up by reflecting long wavelength infrared radiation. Even due to contact with glass, plant leaves will not suffer from the cold.

Myth number 3. Double-glazed windows quickly lose their energy-saving properties

Thermal insulation properties are lost only in the event of destruction of the metal coating (corrosion). With good protection from the external environment, the coating will remain throughout the entire service life of the glass unit. The manufacturer, in turn, must ensure a high-quality assembly of a double-glazed window, fulfilling all the requirements for storage and installation of i-glass.

Myth number 4. Energy-saving double-glazed windows have low noise insulation

The low-emission coating does not affect sound insulation in any way. If you need increased sound insulation, the manufacturer recommends using a soundproof package, which consists of glasses of different thicknesses. The difference in glass thickness eliminates the resonance effect of sound waves that penetrate the room. The noise level drops to 3 dB, which equates to a quiet human whisper at a distance of one meter.
