The new Defender 88PH System is a Passive House Institute (PHI) certified component – a distinguished recognition by the world’s most rigorous energy-based building standard.
Manufactured in Langley, British Columbia, Canada, the Defender 88PH fixed window is a phA certified component and the Defender 88PH tilt and turn window is a phB certified component.
Defender 88PH – PHI Certified Windows
The new Defender 88PH System is a natural evolution in the company’s long-standing history of manufacturing high-performance German engineered windows and doors. The PHI-certified window system delivers outstanding thermal insulation, superior air, water and sound resistance, and proven durability.
Full Range of High-Performance Windows and Doors
The Defender 88PH System joins an already impressive product line-up that includes the Defender 76DS System and the Defender 76TS System, the later being a Passive House suitable component. The range of systems offers building professionals the flexibility to choose the appropriate windows and doors to meet the performance requirements for their projects, including the performance criteria as defined by the Passive House Institute.
Passive House Standard
Buildings designed and built to the Passive House standard require very little energy to maintain a constant, pleasant temperature in all seasons. As a result, not only are Passive House buildings more comfortable for the occupants, but they also consume up to 90 percent less heating and cooling energy than conventional buildings.
The Defender 88PH System will first be introduced at the sold-out Passive House Canada Conference in Vancouver, BC on November 7-8, 2018. Innotech will begin manufacturing the system in January 2019.
