The word facade is French for face or frontage, which explains why in architectural terms, we use this word to describe the exterior elements of a building. This includes everything from walls to glazing and cladding. It is essentially an overcoat that is attached to the outside of a property to protect it.

However, protection isn’t the only role that the facade plays in architecture. In fact, these important exterior elements serve quite a few functions when it comes to ensuring the overall usability of a building.

This is why facade contractors must get everything perfect, right down to the smallest details. In the guide below, we’re going to look in more detail at the reasons why building facades are so important to an architectural project.

1. Protect against the elements

Arguably the most important purpose of a facade is to protect against the elements, mainly the wind, rain and extreme temperatures. Essentially, it must act as a protective shield against the weather and the damage it might do to both the interior and exterior of the building.

This is why it is vital that facades are made from the right materials, as they have to withstand the weather, avoid corrosion and control the climate indoors. They must be strong, sturdy and durable. They need to be able to last for decades and to ensure the longevity of the building.

2. Ensuring ventilation

As the facade is made up of lots of different elements, it is able to control the natural airflow of a building. This is crucial for a number of reasons. For example, it must allow enough ventilation to ensure comfort for the occupants whilst clearing the air of dust or unwanted particles to keep it clean.

However, the facade and building envelope must be tight enough that it does not allow draughts in or for warm air to escape. This is important for climate control and energy efficiency within the property.

3. Making the most of natural light

Glazing is one of the most important parts of a facade, and it’s crucial that this is utilised to make the most of natural light. This is why glass is being used in increasing amounts on building envelopes – that and the fact that it is aesthetically pleasing.

Allowing more natural light into the building through glazing is vital as it reduces the amount of artificial light needed and helps to regulate heating and cooling. This can make the building more energy efficient.

Natural light has also proven to boost the mood and comfort levels of all those inhabiting the property.

4. Increasing acoustic insulation

Another important role of the facade is to stop noise pollution. After all, what good would a building be if you could hear the noise of all the people, traffic and extreme weather conditions outside? Therefore, a good facade must reduce the amount of external noise that can get in but also stop internal noise from going out. This makes it a more comforting environment for all inhabitants.

5. Adding structural support

As a facade is made up of different elements such as glazing, metal framing, cladding, roofing and more, it plays an important role in the overall structure of a building. Again, this is why they must be made from strong, durable materials to reduce the risk of damage to the property.

Although the primary structure will bare most of the weight, elements used in the facade can offer additional support. Other materials may be attached to aspects of the facade to shape the design and boost the structural integrity of the building.

6. Creating the overall look and design

The final reason that a facade is so important is that it contributes towards the final look and design of the building and can help to add value to the property. Whether it’s cladding, glazing or framing, these important design elements will shape the style and aesthetics of the building, particularly when it comes to the use of glass panels.

As such, a facade can add real character and personality to any building, it makes it possible to personalise or customise the design to meet the requirements of the owner.

So, as well as being important for structure and protection, the facade is also vital for making a unique and attractive building.
