[ Technology ]

Not PVC. Not aluminum. Something better.

UwZERO® is made from a patented material: fiberglass-reinforced polyurethane, which combines ultra-low thermal conductivity, extreme structural strength, and durability under any climatic conditions. No warping. No compromises.

[ Why NPU Safe EI90 ]

01 – Thermal

Heat retained in winter. Constant coolness in summer.

Lower energy consumption and consistent comfort in any season.

02 – Structural

Resists impeccably under any conditions.

No deformation, no issues. From extreme frost to high temperatures.

03 – Eco-friendly

Cleaner air in your home. 100% safe material.

Zero emissions, zero odors, suitable for sensitive spaces and families with children.

04 – Functional

More light. Wide openings.

Slim profiles for large glazing areas and more open spaces.
