Aluminium and glass facades are one of the most exciting trends in modern construction. 

A combination of aesthetics, durability and functionality. It is these aspects that architects and designers value most. Not surprisingly, it is precisely this type of window joinery that is increasingly being used in commercial and residential projects. 

But can they make a difference to the energy efficiency of a building? The answer to this question is more complex than it may seem.

Natural light as a way to reduce energy consumption

Did you know that a properly designed aluminium and glass façade can reduce electricity consumption? Large glazings make better use of natural daylight. This will reduce the need for artificial lighting, which will logically translate into lower bills.

Façade systems designed for high light transmission make the most of daylight. At the same time, their special design protects interiors from excessive overheating in summer and heat loss in winter. How? This is made possible by the use of low-emissivity glass, which effectively reflects thermal radiation.

Aluminium-glass systems can be fitted with spectrally selective glass – glass that only transmits wavelengths of solar radiation. This type of glazing transmits visible light and reflects infrared radiation at the same time. This allows the maximum amount of daylight to enter the building, but the room does not heat up excessively. This solution is particularly suitable for office buildings, where natural light is used for many hours. 

In addition, many façade systems allow for the installation of opening windows – the energy-saving benefits of such a solution can be observed through better ventilation of the building and a reduction in the need for air conditioning.

Thermal insulation of facades – why does it matter?

Every building loses heat through its walls and windows. Aluminium and glass facades can reduce the loss by using the right materials and technology. 

Modern facade systems are designed with high thermal insulation in mind. Aluminium frames fitted with thermal breaks effectively reduce heat conduction. As a result, the interior of the building maintains the desired temperature for longer.

An additional advantage is the possibility of using double-glazed units. Their construction allows for reduced heat transmission. 

Modern aluminium and glass facades use innovative thermal breaks made of materials with very low thermal conductivity. Such solutions ensure high insulation while keeping the structure slim. 

An example is the use of special EPDM (ethylene propylene diene) gaskets, which effectively eliminate thermal bridges at the glass-aluminium interface. Interestingly, some systems also use foam insulation inserts mounted inside the profiles, which further improves energy efficiency.

Working with renewable technologies – a modern approach to energy efficiency

Aluminium and glass facades can become part of energy-generating systems. Have you heard about the possibilities of integration with photovoltaic panels? This solution allows the building façade to be used as a source of renewable energy. 

Many façade systems are designed to be compatible with photovoltaic panels. This makes it possible to simultaneously maintain the aesthetics of the building and reduce CO₂ emissions.

Facade-mounted photovoltaic panels also have an additional advantage. They protect the interior from excessive heat and, at the same time, produce energy that can be used to power the building.

An interesting solution in modern façade systems is the possibility of installing photovoltaic modules in a way that is integrated into the façade structure. This means that a building’s façade can have both a decorative and an energy function. This type of solution makes it possible to design so-called zero-energy buildings – buildings that generate the energy needed for their use themselves. 

You can also use facades that are integrated with intelligent building management systems (BMS), which automatically regulate airflow or window opening according to temperature and sunlight.

Durability and low operating costs

By investing in aluminium and glass facades, you not only benefit from energy efficiency, but also from the durability of the materials. Aluminium, which is resistant to corrosion and weathering, does not require frequent maintenance. 

An additional advantage is the recyclability of aluminium. When facades are retrofitted or dismantled, the material can be reused – an ecological solution that supports sustainable construction.

Aluminium, from which façade profiles are made, is one of the most resistant materials used in construction. Thanks to the anodising process, the aluminium surface gains a protective layer, which increases resistance to corrosion and scratching. What is more, modern facade systems use polymer coatings, which further protect the profiles from UV radiation and weathering. Another interesting feature is the possibility of manufacturing profiles from recycled aluminium. What will be the result? A lower carbon footprint for the building. 

Design matters

The aesthetics of aluminium and glass facades are not just a visual issue. Properly designed façades can affect the energy efficiency of a building. By choosing a system with high light transmission and adequate thermal insulation, the building’s potential can be maximised.

Modern facades also offer customisation options. You can choose systems with advanced seals that further improve the airtightness of the building. As a result, you will not only gain lower energy bills, but also greater comfort.

Are aluminium and glass facades the investment of the future?

The answer to this question seems obvious. Aluminium and glass facades combine modern technology, durability and aesthetics. With them, you can reduce your building’s maintenance costs and contribute to environmental protection at the same time.

By investing in such solutions, you not only gain in savings, but also increase the market value of the building. Aluminium-glass facades are not only an architectural element, but also a tool to promote energy efficiency.
