Natural Slate: The Latest Architecture and News

Slate is a metamorphic natural rock composed of clay minerals such as mica and chlorite, which give it a laminated texture and predominant shades of gray, black, and green. Widely used in the construction industry, it is known for its durability and distinct elegance, offering a timeless and sober finish for roofs and exterior walls. With its unique texture, it can transform the look of any structure using rectangular—or other shaped—pieces. Additionally, it is a highly resistant material to weather, fire, and environmental pollutants, ensuring long-term performance with minimal maintenance. Its eco-friendly production process, involving only raw material extraction and minimal processing, reduces CO₂ emissions, making it an ideal choice for sustainable contemporary architecture.

The duality of sunlight in the field of architectural design presents fascinating contrasts, especially when addressing the question of how to interact with it through the built environment and the materials that define architecture. The sun's influence in this discipline has become an essential part of the cultural heritage of some countries, as evidenced by Spanish architecture, where the interaction with sunlight manifests through elements such as lattices. These lattices are recognizable on the facades of buildings from the Middle Ages, exemplified by structures like the Alhambra, to 20th-century constructions such as Casa Gomis, considered historical monuments.

The facade, being the skin of the building, is the architectural component that is usually directly exposed to sunlight. Based on this premise, we seek to establish a dialogue between openness to the environment and the need for protection, thus creating a synergy between functionality and aesthetics. In this context, sunscreen facades have been developed through various approaches, standing out for their ability to address this design condition. For this reason, we have selected solar control solutions from Spanish brands, distinguished by their technical characteristics and materiality through various approaches.

Moving towards modernity implies questioning established concepts. Today, we are witnessing several projects and approaches in architecture that explore alternatives to energy-intensive building systems, materials, and technologies commonly used in today's construction. These projects, far from adopting approaches that reject technology, seek to promote conscious architectural practices. They aim to go back to basics through passive strategies, using natural materials and a contextual understanding to develop sustainable architecture.

To boost sustainable architecture, it is crucial to have building models and materials that become recognizable icons in their immediate context, thus setting a precedent for the development of future proposals. One such example can be found in Spain, with the "Impulso Verde" project carried out in the city of Lugo which stands out for its construction model based on passive strategies and regional materials. In this project, using natural slate as cladding for the ventilated facade system and employing local resources in the structure was essential for the building's ecological footprint. Additionally, these elements strengthen the building's identity by connecting it to the surrounding landscape.

When designing architectural projects, protecting a building’s walls is key for ensuring its longevity, durability, and resistance to the elements, therefore preserving its aesthetic appeal. Among the protective measures available, cladding systems are exterior coverings that integrate varying textures, colors and finishes, allowing for customization and creative expression, while also providing weather resistance and thermal performance. 

Exploring materials beyond traditional masonry cladding or commercial curtain wall systems, Cupa Pizarras has developed natural slate rainscreen facades. From linear to honeycomb patterns, these geometric facade layouts meet the requirements of current architectural trends, which demand more sustainable and energy-efficient buildings. The combination of high-durability tectonic slate with innovative fastening techniques, as well as the efficiency of rainscreen cladding, makes CUPACLAD a sustainable and aesthetically pleasing alternative for enhancing the LEED certification of projects.
