Low-E Insulating Glass

Now, the energy-efficiency and the high aesthetics go hand-in-hand. Create bright, energy-efficient, comfy rooms for living and working, 24/7 all year around with Yalodomi’s THERMOBELT Ultra®. The “secret” of IG product lies in a virtually transparent coating, that allows it to be a net contributor of energy in buildings. Low-E stands for low emissivity, referring to the heat reflective property of the glass. With THERMOBELT Ultra®, one can reduce heat loss through the windows, while allowing great amount of light to enter the building. Low-E technology is applied to both double and triple-glazed windows.

More precisely, Low-E has the following characteristics:

+ excellent insulation values (Ug values)
+ unparalleled light transmission
+ advanced color neutrality (Ra value)

Energy Saving

The energy-efficiency is not anymore just a synonym for environmental friendliness, but also a huge source of cost-savings. With oil and gas prices rising quite frequently, heating cost has become rather exorbitant. It is true that sustainable heating methods, such as Low-E insulating glass, may seem pricey, but in the long-run, they prove to be more cost-effective. Getting the right type of glass is critical, since many buildings use redundant energy and therefore, there are more CO2 emissions than needed to keep people comfortably warm. Low-E glass technology, if massively used, can help to reduce CO2 emissions in the near future.

Investing in Yalodomi’s energy-saving glass you get your money back, since the introduction of the energy Performance Certificate for buildings. There is also a wide range of state funding programs for improving the energy performance of both new and existing buildings.

Using insulating glass from Yalodomi’s THERMOBELT Ultra® series, you can achieve maximum thermal insulation while using solar energy.

Quality of insulating glass

Yalodomi’s THERMOBELT Ultra® series insulating glass types are made of high grade tested materials. The edge connection provides optimum protection from the high strains to which an insulating glass unit is exposed, during its long product life.

The quality of the final product is ensured by external quality control from a certified body and is continuously documented, according to EN 1279-6. Additionally, Yalodomi performs internal quality control tests several times a year.


+ Thanks to the higher surface temperature in the edge area of the inside pane (warm edge) valuable heat remains in the room.
+ Better values of the heat transfer coefficient of the window (Uw-value)
Lower heating energy losses

Most frequently Asked Questions

Q: Why MIGHT my new energy saving glass mist -up fr om the outside?
A: Outside condensate frequently forms on glass, during high humidity nights. The better the thermal insulation of the insulating glass, the more likely the formation of outside condensate. This is an indicator of the high quality of your windows. Due to the excellent insulation value, glazing’s heat transmittance is very low. That means that heat stays inside the room and hardly any of it passes to the outside. The outer pane therefore has a lower surface temperature than the outside air. With the corresponding high relative humidity in the outer air, the dew point on the glass pane is not reached and so condensate forms on the pane surface.

Q: Do I have to ventilate frequently?
A: If you install new windows you improve the air tightness of the room. That saves energy and heating costs. However, the moisture that builds up, no longer escapes to the outside through the new windows. So regular airing is needed after renovation.
