What is UwZERO®?

UwZERO® is a revolutionary window and door profile system made from a patented glass fiber–reinforced polyurethane material, developed in technological partnership with the American company HUNTSMAN

The name UwZERO® comes from its ultimate objective:
– achieving a thermal transmittance coefficient (Uw) as close to zero as possible, without compromising design, strength, or sustainability.

The profiles are Passive House certified by PHI Darmstadt, the European authority in the field

 Key Technical Features

✔ Ultra-Low Thermal Conductivity

0.114 W/m·K – significantly more efficient than PVC or thermally broken aluminum

✔ Fire Resistance

Up to EI 110 minutes fire resistance

✔ Extreme Mechanical Strength

Bending strength up to 1442 MPa, ensuring long-term structural stability without deformation

✔ Zero VOC Emissions

Safe, non-toxic material with 0 volatile organic compounds (VOC)

✔ Corrosion & Salt-Spray Resistant

Ideal for coastal, marine, or industrial environments

✔ Wide Temperature Resistance

Performs reliably from -50°C to +240°C

✔ Non-Metallic & Non-Conductive

Enhanced thermal and acoustic insulation
