Grenzebach: reinventing the window

More stringent energy saving regulations are causing glaziers and, of course, glassmakers, to look for ways to optimize functions, while increasing production capacities. In this article we take a look at a particular technology – vacuum. Not new, we may say, but used in the insulating glass unit field it becomes very new. Its application brings excellent sound insulating qualities, concealed visibility of spacers, along with the possibility of even more improved insulating values in the very near future.

Grenzebach: reinventing the window
Insulated glass windows have been around for 50 years: two glass sheets are bonded together by means of a metal or plastic frame with dry air locked in between. These days, higher-quality heat insulation windows are provided with an argon gas filling instead of air. In addition, metal coatings for the inner sheet sides have been developed over recent decades, which significantly limit thermal radiation towards the outside or incoming solar radiation during the summer. Thus, the U-value (former K-value) of this glass sheet is reduced from three watt per square meter to less than 1.0, relative to the inside/outside per degree K of temperature differential.
The new European energy saving regulation EnEV 2012 means that by 2012 we will probably see the end of the two-sheet-insulated glass window, while in the United States, equivalent regulations will come into effect by 2013.
As a possible solution, the window industry suggests the already well-known three-layerinsulating glass sheet with U-values of up to 0.6 and energy loss still, however, falling below the prescribed limits. Other than the glass industry, nobody is really happy about these heavy insulating glass sheets with a thickness of more than three centimetres.
So: what will the future bring?
These designs can only be improved by using krypton gas filling, which, however is not practical for larger quantities due to cost and environmental reasons.
