Certifications and standards
Every ThermoNord certification can be verified in international public databases. We do not promise performance. We prove it with documentation.
Passivhaus (PHI)
Passivhaus certification is awarded by the Passive House Institute (PHI) in Darmstadt, Germany, the most rigorous energy-efficiency standard in the world.

- Tested and certified by the Passive House Institute in Darmstadt
- Window thermal transmittance (Uw) below 0.8 W/m²K, exceeding European energy-efficiency standards
- Certification for the complete system, including both frame and glazing, not just individual components
- Verifiable in the public PHI database
