Modern double glazed units provide not only more comfort, light but they also save a lot of thermal energy. The heat transfer coefficient, the Ug value, is a key indicator of thermal insulation. The lower the value, the more energy is saved.
ETNA UAB single or two chamber double glazed units meet the highest energy efficiency and quality standards, so you can be sure of reduced energy consumption for space heating!
Glass units with Low E 1.1 coating meet today’s market requirements in the field of energy saving. High light and solar transmittance indicators allow the maximum benefit of natural daylight and solar energy to be felt inside the building.
Glass units with selective coating Low E 1.1 can offer up to three times better thermal insulation indicators compared to a standard glass unit without selective glass, due to this, greater comfort will be felt inside the building.
And if you need increased security, you can choose a laminated or tempered version of this glass!
Energy 1.1 – selective glass, used in various glass units, for new construction or renovation:
Used in single or double-chamber glass units with a warm frame.
This glass is suitable for use with all possible window frames.

Glass units with Low E 1.0 coating create exceptionally good thermal insulation, which maintains comfort in your home all year round. The coating not only reduces energy consumption, but also the cost of heating the building.
Due to the higher temperature of the inner glass, the likelihood of fogging of the inner glass is also reduced.
Low E 1.0 coating is used in various glass units, with all possible window frames.

ECLAZ LUMI glass is a source of light and well-being. It is a new generation of Saint-Gobain Low-E glass for premium glass units. It is manufactured using advanced industrial technology.
ECLAZ LUMI glass opens up new possibilities for windows with two or three glass units.
Aesthetics, thermal insulation, plenty of solar heat in winter, natural light – ECLAZ LUMI allows you to meet the highest requirements. Products with this glass allow windows to make a positive contribution to the challenge of saving energy in a building.
ECLAZ LUMI is designed for triple-glazed windows, mainly in new residential and non-residential buildings, passive houses and other high energy efficiency A+, A++ buildings.
It can achieve a Ug=0.5 W/(m2.K) value with the highest total solar energy transmittance on the market (up to 60%).
ECLAZ LUMI glass is also available for double-glazed windows with Ug=1.1 W/(m2.K), which transmits as much as 71% of solar energy.
ECLAZ LUMI is recommended for:
With ECLAZ LUMI glass, you no longer have to choose between natural light and heat preservation.
