Environmental Benefits
Sustainable Materials
Various modern cladding materials are produced using renewable resources and sustainable practices. For example, composite materials can incorporate recycled content, and natural materials like timber can be sourced from environmentally responsible managed forests.
Energy Efficiency
Lowering greenhouse gas emissions is a direct result of improved thermal insulation, cladding materials can reduce the buildings energy consumption from reducing the need for heating and cooling inside the structure.
Green wall façade systems, also known as “vertical green walls,” where plants envelope the exterior wall of a structure improves acoustic performance, thermal insulation and indoor air quality.
A rainscreen façade features a two-layer system for excellent waterproofing, durability, and thermal efficiency. It deflects most moisture with its outer layer, while the inner cavity handles any remaining moisture through ventilation and drainage. This system enhances insulation while reducing energy consumption and protects buildings from weather damage.
Recyclability
Cladding materials, such as terracotta and fibre cement, are recyclable at the end of their lifecycle and contribute to the circular economy, guiding the movement towards more sustainable opportunities.
EPD
An EPD is an independently verified and registered document that provides clear information on a product's environmental impact throughout its life cycle, from production to disposal. By specifying products with an EPD, architects can be confident in their sustainability and minimize environmental impact.
Building Performance and Safety Compliance
Weather Protection
Façade cladding acts as a protective barrier against weather elements such as rain, wind and UV radiation, in result the building’s exterior and underlying structural elements are protected against deterioration and therefor extend the lifespan of a structure.
Fire Resistance
Modern cladding materials are meticulously designed to meet fire safety standards and regulations. Both metal and fibre cement are fire-resistant materials that help contain fires, act as a preventative measure and enhance the safety of a structure.
Acoustic Performance
Cladding systems can act as acoustic insulation, reducing noise transmissions from external resources and improving indoor acoustics; this being highly beneficial for buildings located within urban areas.
