Passive House Windows
Improved Thermal Comfort

Buildings account for around 35% of total global energy consumption. A large percentage of which comes from the use of heating and cooling systems. Passivhaus is the most stringent building standard in the world that reduces the energy demand in a building and optimises thermal comfort, ensuring that at the same time there is plenty of clean, fresh air.

Passivhaus buildings aim to improve thermal insulation and airtightness, with fresh air being provided mechanically, providing optimum thermal comfort for residents. Passivhaus windows perform well beyond current UK building regulations, with Uw-values of installed windows required to be below 0.8W/m²K.

What cannot be underestimated is the impact of solar gain. Suitable shading, whether natural or other, are an important consideration when building any home, especially when integrating large glazing on south or south-west facing elevations.

Internorm not only manufactures high-performance triple glazed windows in sustainable timber-aluminium composite and uPVC-aluminium, but also offers suitable shading solutions.

Passivhaus Windows for Newbuild & Retrofit Projects

Energy-efficient triple glazed windows prevent heat loss, significantly reducing energy consumption and therefore heating costs required in a building.

Internorm Passivhaus windows feature triple glazing, triple gaskets and insulated frames to ensure optimum insulation and airtightness.

Passivhaus - the Standard for Future Buildings

The Entopia Building: A Showcase of Sustainability

The Entopia Building is home to the prestigious Cambridge Institute for Sustainability Leadership (CISL). This ultra-sustainable retrofit boasts Internorm HF 410 timber-aluminium composite windows throughout. Imagine the impact these windows can have on your next project – reducing energy consumption, lowering heating costs, and contributing to a greener future.

Internorm Passivhaus windows are ideal for commercial projects, such as large residential, schools and educational buildings, care homes, hotels, and any building where energy-efficiency and thermal comfort are of importance.

Whether specifying windows for a Passivhaus newbuild or EnerPHit retrofit project, choosing high-performance windows has never been more important.

PassivHaus Buildings

There are certain guidelines for PassivHaus windows and projects, including the use of solar power, minimal heat loss, and energy-efficient windows. At Internorm, our windows are suitable for PassivHaus projects because we use specialist technology to create energy-efficient windows that utilise solar energy.

Our solar glass helps to reflect light from the sun using shading technology to prevent overheating. This means that your home can retain heat at a comfortable temperature and still cool itself without the use of an aircon unit or electric fans.

Other Benefits of Passive House Windows

As well as providing exceptional thermal insulation, Passive House windows have a range of other benefits. For example, timber-aluminium composites offer unrivalled strength. The aluminium outer profile is up to five times stronger than other windows on the market.

Additionally, Passive House windows also contribute to noise reduction. The tight seal improves soundproofing abilities, decreasing noise by up twelve times!
