110 Series Passive House Windows

The 110 Series is our Passive House Institute certified window, designed for low-energy, near-zero and Passive House standard buildings. Independently tested and registered as Component-ID 2472wi03 (valid until 31 December 2026), the system delivers a Uw of 0.80 W/(m²·K) — verified, not theoretical — alongside 37 dB sound insulation, Class 9 wind resistance and the wider glazing pocket (39-40mm or 49-50mm) that low-energy construction demands. The 110mm frame depth and 30mm multi-chamber thermal break are combined with concealed Siegenia hardware as standard, or Sobinco concealed hardware as the high-spec upgrade, plus EPDM seals across the three-seal perimeter. Suitable for residential, multi-storey and institutional projects targeting Passive House, LEED, BREEAM or other stringent low-energy certifications.
