Aluminium joinery, just few years ago, was associated mainly with office buildings and commercial properties. However, this perception has changed significantly. Today, aluminium windows and doors are widely used in modern single-family houses, luxury residences and premium apartments. This shift occurs because aluminium meets the current expectations of investors and architects. It is chosen especially for projects with large glazing, minimalist architecture and maximum daylight access.
Aluminium and large glazing – why is it the perfect combination?
One of the main reasons aluminium joinery dominates large glazing projects is its high rigidity and structural stability. Aluminium allows the design of large windows and doors without compromising safety or durability. As a result, architects can implement bold concepts that were difficult to realise in the past.
In practice, this includes floor-to-ceiling glazing and large sliding doors. Moreover, aluminium enables corner windows without visible mullions. Slim profiles are also possible. Consequently, the glass surface increases and interiors receive more natural light. For this reason, spaces feel brighter, larger and more connected to the surroundings.

Which projects benefit most from aluminium joinery?
Aluminium joinery is not suitable for every type of building. Nevertheless, it performs exceptionally well in specific architectural projects. It is most often chosen for modern single-family houses that feature large glazing, simple forms and clean lines. In such designs, architectural consistency, daylight access and visual impact play a crucial role in achieving a contemporary look.
In addition, aluminium joinery is frequently used in luxury residences and modern villas. This is because aluminium windows and doors enhance prestige and emphasise a modern architectural character. Aluminium windows and doors are also a standard solution in premium apartments and high-end residential developments. Furthermore, aluminium systems have been widely applied in commercial buildings and office architecture for many years. Architects choose aluminium joinery especially when other materials limit design flexibility, glazing size or minimalist detailing.
Key properties of aluminium joinery
Choosing aluminium is not only about aesthetics. It is also a technical decision. First of all, aluminium maintains dimensional stability despite temperature changes. Therefore, it is ideal for large-scale constructions.
At the same time, aluminium allows slim and elegant profiles. These profiles align perfectly with modern architectural trends. Durability is another advantage. Aluminium joinery resists moisture, UV radiation and corrosion. As a result, it requires minimal maintenance and offers long service life.
Moreover, modern aluminium systems use thermal breaks and advanced glazing units. Thanks to this, they meet energy-efficient building requirements. Besides, aluminium offers wide customisation options. Colours and finishes can be matched easily to the façade design.

Modern aluminium joinery in practice – Bertrand solutions
A strong example of modern aluminium joinery is found in the offer of Bertrand. The company specialises in aluminium window systems designed for contemporary architecture. These solutions meet both aesthetic and technical expectations.
One of the most popular systems is Slimline 38. It is currently the most frequently chosen aluminium product in the Bertrand range. This is because Slimline 38 combines ultra-slim profiles with excellent performance. As a result, interiors gain maximum daylight while façades remain elegant and modern.
Importantly, Slimline 38 enables large glazing without structural compromises. Therefore, it is often selected for modern houses and premium apartments. In addition, Bertrand offers other aluminium window and door systems. They are suitable for residential and commercial buildings alike.

Is aluminium joinery a popular trend in Poland and abroad?
In Western Europe, Scandinavia and the United States, aluminium joinery has been standard for years. Large glazing and sliding systems are common solutions there. This applies especially to modern residential architecture.
In Poland, the trend is also growing rapidly. This happens because investor awareness of design is increasing. Modern house projects with large glazing are becoming more popular. At the same time, access to advanced aluminium systems is improving. As a result, aluminium is no longer seen as a niche solution.
Moreover, joinery is now treated as a design element. It is not only a technical component. Consequently, aluminium’s market share continues to grow. Although it still dominates mainly in mid-range and premium projects, its popularity is clearly rising.

Aluminium joinery responds directly to the needs of modern architecture. It works especially well for large glazing and minimalist designs. Investors choose it because it combines durability, aesthetics and design freedom.
Systems such as Slimline 38 by Bertrand clearly show why alu systems is one of the strongest joinery trends today. This applies both in Poland and internationally.
