NPU SAVE Ug
0.34 W/m2K®
A different kind of glass.

Exceptional thermal performance. 8.3 mm profile. Suitable for any building.

The window you can't see. The comfort you can feel.

NPU SAVE Ug 0.34 W/m2K® is the first vacuum glazing technology available in Romania, designed for both new and heritage buildings.

[ Technology ]

Vacuum between two panes of glass. Nothing else.

Two 4 mm tempered glass panes, separated by a vacuum layer. Result: a total thickness of 8.3 mm with a thermal coefficient Ug of 0.4 W/m²K. Performance comparable to classic 36 mm triple glazing.
