What is a Passive Window?

Over the years, we've seen many changes in the way house are built. Nowadays, we understand the value of good insulation that both keeps the heat inside and reduces our carbon footprint.

As you might have guessed, passive homes are properties that aim to use the least amount of energy possible for all heating and cooling. First seen in Germany, the idea is currently very popular in the UK, Ireland, and the US. Alongside the likes of insulation, windows play an important role in passive homes and this is what we are expert in at Rationel, developing beautiful windows and doors suitable for both modern and traditional 'Passiv Haus' buildings.

For every home, windows are important because not only do they offer insulating properties but they can use free solar heat, provide shading, offer air tightness, and thermal bridges. At Rationel, we've come to learn that every single home is unique so there is no universal solution we could apply. Instead, each home needs to be assessed for space, style, and so we like to met our customer s and spend time with them so each person's individual needs can be discussed.

Whenever a home becomes efficient enough and passes certain standards, they can actually obtain Passive House status. While this will require more than just installing new windows, they are part of the criteria so serve as one part of the overall requirements. Understanding the relationship between energy performance and building design is essential because there is no one-size-fits-all approach.

While helping the environment, let's not forget that passive windows can also help you to save money and stay warmer during the cold winter months. If your windows are insulated, the heat can stay inside rather than seeping through outside (while also allowing cold air in!).
