What Are Passive House Windows?

A Passive House window has been designed to offer outstanding thermal performance to any UK property they’re installed into. 

The Passive House standard provides a high level of comfort for properties, whilst using very little energy for both heating and cooling. 

 “A Passivhaus is a building in which thermal comfort can be achieved solely by post-heating or post-cooling the fresh air flow required for a good indoor air quality, without the need for additional recirculation of air.” – Passivhaus Institut (PHI)

The Passive House windows we offer to our Distribution Partners are manufactured with meticulous attention to detail. The Passive House windows go through rigorous testing that meet the principles first developed by the Passive House Institute in Germany. It is through a quality and testing process that the Passive House windows are given their status.

Why Choose Passive House Windows? 

Passive House windows are ideal for low energy properties looking for energy efficient window systems that will provide optimum levels of comfort throughout the year. 

The Passive House windows are characterised by their thermally broken and air tight profile. They are usually triple glazed with the panes of glass filled with argon or krypton gas.

This innovative design will provide ultra U-values as low as 0.62, which will help to minimalise heat loss, and keep your UK property warm and comfortable year after year. With Passive House windows you’ll get the most energy for the least effort or cost and retaining this for long periods of time. 

 Passive House windows have to reach a certain standard to achieve the certification. To have a certified Passive House, the windows must boast a U-value of 0.8 or lower and the buildings energy consumption and air leakage are taken into consideration.

Passivhaus Certification – What’s the Difference?

As the Passivhaus principal has been spreading all over the world, Germany has advanced the Passivhaus certification. Dr Feist, who founded the Passivhaus idea, is the owner of the private organisation “Passivhaus Institut” in Darmstadt, which developed this building standard 20 years ago and managed to spread it into many countries.

The independent test centre Rosenheim (like the BBA in the UK) has developed a new Passivhaus certification for windows and thereby has
achieved an official standard. Dr Feist is only interested in the thermal performance, whereas Rosenheim is also interested in the physical tests of the window and its performance, like water tightness, air permeability and shock resistance.

The thermal performance of Rosenheim’s certification is more detailed – it does not state the PSI or Uf value, but instead details the temperature factor of the glass edge and of the main building. It also measures the average
temperature factor of the frame profile as well as the Uw installed.
