Is there still a place for aluminium in the edge seal of insulation glass units?

-

We’ve been her before: In 1973, a global energy crisis had already directed focus to the energy efficiency of buildings. With the Thermal Insulation Ordinance of 1977, single-pane glass was banned, coated insulating glass quickly became the standard and the Uw value dropped substantially.

The new Ultimate Pro complements the existing portfolio of spacers from Swisspacer. The optimised material ensures that the spacers are particularly elastic.

Warm Edge

-

In multi-pane insulating glass, a warm edge is an edge seal in which the spacer between the panes of glass is made of materials with low thermal conductivity.

According to H.B. Fuller | Kömmerling, the new Loca elements with Clear Edge for the first time combine the design advantages of liquid lamination with an edgeless, fully transparent look.
