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.

[ Suitable systems ]
Suitable for old buildings.
Essential for new buildings.
Heritage
Historic buildings cannot be structurally altered. NPU SAVE Ug 0.34 W/m2K® is fitted into the existing window frames, with no interventions and no compromise on aesthetics.
New construction
Passive houses, NZEB buildings, high-efficiency commercial and residential spaces. NPU SAVE Ug 0.34 W/m2K® meets today’s most demanding energy standards.
[ Uncompromising safety ]
Advanced technology that enables integrated fire resistance
It reduces risks and increases building safety, contributing to the sustainability of the investment.
The glass is tested to withstand extreme temperatures for defined periods (EI30, EI60, EI90, etc.), maintaining integrity and insulation in the event of a fire.
It meets fire protection standards while preserving performance and architectural coherence.
It can be configured together with advanced profiles and solutions without affecting the overall performance of the glazing.
It allows large glazed surfaces to be kept, even in areas with strict safety requirements.
Freedom. Proportions. Minimalism.
