What is a Passive House?

Passive House is a leading building standard that enables you to build comfortable, low-energy homes that offer the ultimate level of comfort and insulation whilst reducing the building’s ecological footprint. Established in Germany in 1996 by the Passivhaus Institute, the core focus of a Passive House building is to ensure your space reduces the requirement for heating and cooling.

Most commonly used in new builds, a Passive House window needs to be twice as efficient as your standard window and must not exceed a U-Value of 0.8 W/(m²K), amongst many other specifications.

Internorm offers a range of pioneering Passivhaus window systems that have been meticulously designed and constructed to meet the requirements for a ‘Passive Home’. With a combination of materials and innovative I-tec solutions, our products will reduce the demand for space heating, provide exceptional levels of airtightness and thermal comfort as well as solar shading and ventilation.
