Why choose our aluminium doors and windows?
Our aluminium windows and doors are designed to meet the most demanding requirements of modern architecture: they are durable, feature a clean and refined design, yet deliver outstanding technical performance. Thanks to the combined expertise of the Berg System and Schüco profile systems, our clients receive premium aluminium doors and windows that:
- provide excellent thermal and acoustic insulation, meeting even passive house standards;
- offer exceptional resistance to weather conditions, maintaining their aesthetics and flawless operation for decades;
- enable the use of large glass surfaces with slim frame profiles, allowing maximum natural light to enter the building;
- are available in a wide range of shapes and colours (RAL colour palette, matte or textured finishes, including wood-effect coatings), making them suitable for modern, minimalist, as well as classic or elegant architectural styles.

The aluminium portfolio of Berg System covers every requirement — whether it is a traditional window, an elegant entrance door, a panoramic sliding door, or a modern glass façade:
- Aluminium windows – slim profiles, contemporary design, and large glass surfaces;

All our systems are built using Schüco premium profile systems, ensuring that our aluminium doors and windows represent the highest level of technology, performance, and quality.
Technical Advantages – What Premium Aluminium Windows and Doors Deliver
Thermal and Energy Efficiency
Schüco aluminium window systems (e.g. AWS 75 SI+, AWS 90.SI+) provide an outstanding level of thermal insulation, meeting even passive house standards. This significantly reduces heating and cooling costs while improving the overall energy performance rating of the property.
Durability and Weather Resistance
Aluminium does not corrode, warp, or deform, and is highly resistant to UV radiation, rain, and frost. Even after decades of use, it remains structurally stable and visually refined—an essential advantage for large glass surfaces and modern façades.
Clean Design, Large Glass Areas, Maximum Natural Light
Slim visible frame widths, minimalist profiles, and expansive openings allow window and door frames to remain almost invisible, letting natural light dominate interior spaces—a key requirement of contemporary architecture.
Security and Reliable Operation
Schüco profile systems are engineered with multi-point locking mechanisms, concealed premium hardware, high-performance glazing, and weather-resistant surface finishes. As a result, aluminium doors and windows provide exceptional security and long-term reliability.
Low Maintenance
Unlike timber windows and doors, aluminium systems do not require periodic surface treatment. With simple cleaning, they retain their original appearance for many years, ensuring long-lasting aesthetics with minimal maintenance effort.
