PHIUS Certified Fiberglass Reinforced Polyurethane

UwZERO® is a revolutionary window and door profile system manufactured from a patented material: glass fiber-reinforced polyurethane — an advanced composite that combines outstanding thermal performance, exceptional structural strength, superior fire resistance (up to EI 110 minutes), and long-term durability in all climate conditions.

Developed in technological partnership with the American company HUNTSMAN, UwZERO® represents a next-generation solution for high-performance building envelopes.

The name UwZERO® reflects its ultimate objective: achieving a thermal transmittance coefficient (Uw) as close to zero as possible, without compromising design flexibility, structural integrity, or sustainability.

UwZERO® profiles are certified for Passive House performance and meet the rigorous energy efficiency requirements demanded by high-performance buildings.
For projects targeting North American standards, UwZERO® can be aligned with PHIUS (Passive House Institute US) performance criteria, ensuring compatibility with climate-specific passive building requirements.

In a market where energy efficiency, durability, and fire safety are essential, UwZERO® delivers a comprehensive solution that exceeds conventional PVC and aluminum systems.
