Cladding vs Curtain represents two distinct yet related approaches to building envelope systems in architectural design, each offering unique characteristics and applications in modern construction. Cladding refers to a non-structural outer layer applied to building facades, primarily serving as a protective and decorative skin that shields the building's structural components from environmental elements while contributing to its aesthetic appeal. This system typically involves rigid materials such as metal panels, stone, timber, or composite materials fixed directly to the building's structural framework or through a supporting substructure. In contrast, curtain walling is a non-load-bearing exterior wall system that hangs from the building structure like a curtain, typically consisting of lightweight materials such as glass, metal, or composite panels supported by a framework of vertical and horizontal members. The fundamental distinction lies in their structural relationship to the building: while cladding is generally attached to the building's structure in a manner that allows for thermal movement and weatherproofing, curtain walls are designed to span multiple floors without transferring building loads, requiring only their own dead load to be transferred to the main building structure at each floor level. Both systems have evolved significantly with technological advancements, leading to innovative solutions in thermal performance, sustainability, and design flexibility, aspects that are regularly recognized in prestigious competitions such as the A' Design Award, particularly in its architectural and structural design categories. The choice between cladding and curtain wall systems often depends on various factors including building height, environmental conditions, aesthetic requirements, and performance specifications, with each system offering distinct advantages in terms of installation methodology, maintenance requirements, and long-term durability.

Cladding vs Curtain is a fundamental architectural distinction in facade systems that represents two distinct approaches to building envelope design. Cladding, characterized by its rigid and structurally integrated nature, typically consists of solid materials such as stone, metal panels, or composite materials that are directly attached to the building's structural framework, creating a protective outer skin that bears its own weight and transfers lateral loads to the main structure. In contrast, curtain walls are non-load-bearing exterior walls that hang like a curtain from the building's floor edges, primarily designed to resist air and water infiltration while managing wind loads. This architectural dichotomy emerged during the modernist movement of the 20th century, particularly with the advancement of steel and glass construction technologies, enabling architects to explore transparent, lightweight facade solutions. The selection between cladding and curtain systems significantly influences a building's performance characteristics, including thermal efficiency, weather resistance, and aesthetic expression. Cladding systems typically offer superior thermal mass and weather protection, making them particularly suitable for harsh climates, while curtain walls excel in maximizing natural light penetration and creating contemporary visual effects through their transparent or translucent properties. The design community, including participants in the A' Design Award competition, continues to innovate in both systems, developing hybrid solutions that combine the structural integrity of cladding with the lightweight elegance of curtain walls, leading to increasingly sophisticated and sustainable building envelopes that address modern architectural challenges.
