Curved profiles in building renovation
Building renovation is an essential practice to preserve architectural heritage, improve energy efficiency, and modernize urban structures.
Over time, buildings require interventions not only to ensure their stability but also to adapt them to new needs in terms of comfort and sustainability.
In these renovations, the use of curved aluminum and steel profiles plays a key role in restoring building façades, offering both aesthetic and functional solutions that preserve architectural identity while embracing innovation.
Sustainable renovation with aluminum and steel profiles
One of the main benefits of structural renovation is its contribution to urban sustainability. Rather than demolishing and rebuilding from scratch, renovation allows for optimized resource use, reduced waste, and improved energy efficiency in buildings.
In this process, building insulation plays a crucial role, as a well-executed renovation can significantly reduce a building’s energy consumption, providing greater thermal and acoustic comfort.
Among these improvements, installing aluminum window profiles or curved steel profiles in ventilated façades helps optimize the building’s energy performance. These solutions not only provide high-quality aesthetic design, but also enhance the durability and resistance of the renovated structures.
The importance of curving in façade renovation
In façade renovation projects, the use of curved aluminum and steel elements has become an essential resource. Thanks to the versatility of these materials, innovative architectural designs can be adapted to existing structures without compromising their integrity. From aluminum frames to rectangular aluminum tubes, curving allows for customized shapes tailored to each project’s needs.
Mabelux, with its experience in curving structural aluminum profiles, has taken part in numerous renovation projects in landmark buildings. Our work has been key in ensuring precision and quality in each intervention, always respecting the original design and meeting the most demanding technical requirements.
Renovating iconic buildings with curved aluminum and steel
Renovating iconic buildings requires advanced technical solutions that respect the original architectural essence while offering structural improvements.
For Mabelux, contributing our expertise to breathe new life into these architectural gems is always an exciting challenge. Alongside façade renovation companies, we have been involved in many projects.
Among the most recent, these stand out as emblematic—and close to home—projects we are especially proud of.
Renovation of the La Rotonda Building, Barcelona
The iconic Torre Andreu building, commonly known as La Rotonda, is a major project in which Mabelux actively participated. Under the direction of architect Alfred Arribas, this renovation aimed to recover the original structure to the fullest extent, respecting its modernist design and enhancing its architectural value.
Mabelux was in charge of curving stainless steel profiles from the Janisol series by Jansen, a key element for restoring the façade and the modernist pavilion.
Thanks to this intervention, La Rotonda has regained its original splendor, becoming once again a landmark of Barcelona’s urban landscape.
Sant Antoni Market, Barcelona
One of our most significant projects was the renovation of the Sant Antoni Market, a building of great historical and architectural value. Designed by architect Antoni Rovira i Trias and inaugurated in 1882, this market has remained a point of reference in the city.
Restoration work began in 2007 and extended until 2018 due to archaeological remains discovered in the area, including the Via Augusta and a Roman necropolis.
Mabelux contributed its expertise in curving stainless steel profiles from the Jansen brand for the fabrication of numerous windows, helping restore the façade and modernize the building while preserving its historical essence.
Renovation of Les Arenes Shopping Centre, Barcelona
Another outstanding example of structural renovation is the transformation of the former bullring Las Arenas into a modern shopping center. This project presented multiple challenges, including the preservation and elevation of its Mudejar-inspired façade to accommodate its new function.
Mabelux played a key role in this renovation by applying its knowledge in the fabrication of small-radius portholes, ensuring excellent watertightness and superior precision. Thanks to the versatility of structural aluminum profiles and specialized curving work, it was possible to maintain the building’s original essence—now a cultural and commercial landmark in Barcelona.
Renovating more contemporary buildings with aluminum and steel profiles
Buildings constructed in the second half of the 20th century, especially in urban expansion areas, are now the focus of major renovation projects. While these structures may not be as old as historic buildings, they require significant improvements to meet current standards of energy efficiency, comfort, and aesthetics.
Using aluminum and steel profiles in façade and enclosure upgrades has become a key solution. Due to their strength, lightness, and versatility, these materials improve buildings’ thermal and acoustic insulation, reduce energy consumption, and provide greater comfort for occupants.
Moreover, renovations using these profiles not only bring aesthetic improvements by modernizing the buildings’ appearance, but also ensure greater durability and ease of maintenance.
With curved profile techniques, it’s possible to design innovative architectural elements without altering the original structure, ensuring a harmonious integration with the urban environment.
Building renovation is not only necessary to preserve architectural heritage, but also an opportunity to improve the energy efficiency and safety of constructions—regardless of when they were built.
Investing in façade renovation with high-quality materials not only preserves the past, but also ensures a more efficient and sustainable future for our cities.
