Better with Thin Glass

Triple insulating glass offers excellent thermal insulation values and has become the standard glazing over last couple of years. However, a conventional triple pane construction also brings disadvantages: thicker and considerably heavier than a double glazing, it adds complications to the installation. Furthermore, the heavier weight necessitates reinforced profiles and fittings for windows and facades.

Lighter Triple Insulating Glass
This is why we recommend a triple build-up with tempered thin glass panes. Not only does such a construction reduce weight, it is also better suited to deal with the climatic loads. A possible element build-up would consist of a 4 mm float glass pane on the outside, a semi-tempered 2 mm thick intermediate pane and a 3 mm float pane on the inside. This unit achieves an Ug-value of 0.6 W/m2K and 71% light transmission with a weight of only 22.5 kg/m². With 50%, the energy transmittance is comparable to that of a double insulating glass.  Equivalent sound insulation is also ensured.

Ideal for Building Modernization 
The low weight, excellent thermal insulation value and most of all the easy production make the new, lighter triple insulating glass extremely attractive also compared to vacuum insulating glass. Thin glass makes it possible to produce narrow triple elements which are ideally suited for the modernization of buildings. With the same element thickness, the thermal insulation value can be improved by 100%. The light triple insulating glass is ready for the market as triple build-ups with thin glass can be produced without problems with existing insulting glass lines and LiSEC plants.
