SGG EcoClear® works
Windows glazed with SGG EcoClear® allow optimal amounts of the sun’s energy to pass through the glass into the room allowing your home to benefit from FREE solar heat gain.
At the same time, using advanced glass coating technology, SGG EcoClear® reflects the heat inside your house back into the room rather than allowing it to escape. Both features reduce or eliminate the need for additional heating.
In fact, SGG EcoClear® offers up to 3 times more thermal insulation than standard double glazing and 20% better insulation than old fashioned thermally insulating glass. All this without compromising the amount of natural light passing through the glass into your home.
