Claddings

Cladding is the exterior or interior layer attached to a building’s structural envelope to protect the underlying structure and define its appearance. It provides weather resistance, moisture management, thermal insulation, and architectural expression. Modern claddings range from traditional brick and stone veneers to metal panels, fiber cement, vinyl, wood, glass, and composite systems. Exterior cladding forms the main weather barrier, while interior claddings influence aesthetics and, in some cases, fire or insulation performance.

Common materials and assemblies include brick or stone veneers; aluminum or steel panels; fiber cement boards; vinyl siding; timber cladding; ceramic or porcelain panels; and exterior insulated and finish systems (EIFS). Composite options, such as aluminum composite panels, combine a faceted metal face with an insulating core. Cladding is typically fixed to a structural frame and may be installed over a ventilated rain-screen cavity to allow drainage and drying.

Performance depends on material, detailing, and installation. Key considerations are weather tightness, air leakage, fire safety, durability, and insulation value. Fire classifications follow regional standards; some claddings are non-combustible, others require protective detailing. Typical installation uses mechanical fixings or adhesives, with joints sealed and, in ventilated systems, gaps for moisture control.

Maintenance and lifecycle vary by material. Brick and stone offer long service lives with little upkeep; vinyl, timber, metal, and fiber cement products may require periodic cleaning, sealing, repainting, or replacement. Sustainability factors include embodied energy, recyclability, and energy benefits from improved envelope performance. Cladding choices affect cost, durability, safety, and appearance in residential, commercial, and high-rise projects.
