What are the benefits of Passive House windows?

A Passive House window should not be considered a brand or type of window; it relates more to the window’s thermal insulation characteristics. Passive House is a fast-emerging standard which requires buildings to use a minimal amount of energy for heating and cooling the air temperature, controlling the living environment.

It was a method first developed in Germany, but has since taken off in Scandinavia and North America as it has dramatically reduced the energy consumption of properties in even the harshest, coldest climates.


As a building standard and construction concept for energy efficiency, comfort and affordability, Passive House provides consistent, comfortable temperatures all-year round: minimising both solar gain in the summer months and heat loss and drafts in the winter. Passive houses therefore have to be exceptionally well-insulated and virtually airtight.

The impressive thermal insulation properties of a Passive House window are largely due to its high-quality frame technology, combined with triple glazing.

So what do you need to look for in a Passive House window?

The first port of call is to ensure the window has a U-value less than or equal to 0.8 W/m²K, making it suitable for installation both in Passive Houses and regular properties where enhanced living comfort and substantially cheaper energy bills are welcomed.

It’s imperative that a Passive House window does not allow any drafts or pockets of cold air around the window; nor does it allow for changeable temperatures in close proximity to the window itself.

The inside surface temperature of a Passive House window should be maintained above 17 degrees – even in the coldest winter months. This works to ensure more uniform interior temperatures.

Due to the good insulation surrounding the window pane, central heating does not need to be confined to the window area. This gives property owners much more flexibility in the design of their interiors when redeveloping their aspirational home.

It’s important to consider your bottom line too: the additional costs of installing a Passive House window are quickly outweighed by the high level of energy efficiency it brings, saving you money in the long term with greatly reduced heating bills. Natural heat from the sins radiation is used more efficiently to minimise annual energy charges.
