Passive House Doors
Improving Energy Efficiency in Homes Across the UK

According to the PassivHaus Trust, buildings account for 35% of total global energy consumption. A large part of that comes from the use of heating systems. PassivHaus is an international design standard that aims to improve the energy efficiency of buildings by reducing the amount property owners rely on central heating.

Alternatively, they promote the installation of solar panels as a renewable energy source and energy-efficient doors to help retain heat. Passive House doors boast energy efficiency beyond UK standards, with U-values as low as 0.6W/m²K. Timber-aluminium composites offer unrivalled thermal insulation that prevents heat escaping.

The PassivHaus Trust are an independent organisation raising awareness of the environmental climate crisis and promoting ways to reduce our carbon footprint in the UK by improving building energy efficiency. At Internorm, we are proud members of the PassivHaus Trust. We manufacture and supply highly energy-efficient doors that work to not only prevent heat escaping but also utilise heat from the sun through the use of solar glass and advanced shading technology.

Passive House doors work by using and managing external heat, such as from the sun, to retain heat within buildings, keeping them warmer for longer. A key element is that they prevent heat escaping so that there is less need to rely on central heating.

They feature an effective airtight seal that can achieve astonishing insulation levels with minimal thermal bridges. Another typical feature is mechanical ventilation systems that improve the air quality inside.

Enhance Your Commercial Space


Passive House doors make an excellent addition to commercial projects because larger buildings typically emit more carbon as it takes more to heat them. By installing Passive House doors in office blocks, schools, and hotels, for instance, you can reduce your carbon footprint.

They are equally as great for commercial new build renovations, especially because, as an added bonus, you can even reduce your energy bills. This is because they utilise solar energy to retain heat whilst shading technology helps them stay cool by themselves, hence ‘passive’.

PassivHaus Buildings


There are particular guidelines for PassivHause buildings, including the use of solar panels, minimal heat loss, and energy-efficient doors. Doors are often where homes lose heat the most, which is crucial to attaining minimal heat loss.

At Internorm, we have formulated solar glass that helps to reflect light from the sun to prevent overheating. Our shading technology further helps to keep your building at an optimal temperature without the use of an aircon unit or electric fans.

Other Benefits of Passive House Doors


As well as providing exceptional thermal insulation, there are many other benefits of Passive House doors. For example, timber-aluminium composites have inherent strength, which makes them a secure option for any commercial project. The profiles are up to five times stronger than other doors on the market!

Passive House doors also help contribute to better noise reduction. The tight seal improves soundproofing abilities, decreasing noise by up to twelve times better. This is particularly helpful if your property is in a busy city centre.
