Terracotta cladding

Types of terracotta cladding

Terracotta cladding is a ceramic material with numerous applications in construction. Architects and designers love to use it because of its aesthetic, functional, and sustainable features as a building envelope component. It is used as exterior wall coverings for residential and commercial buildings and offers a sophisticated appearance with its earthy hues and textured surfaces.

Terracotta cladding comes in different shapes, sizes, and finishes. Below are the most common types of terracotta cladding:

• Terracotta Ventilated Facade:

  The ventilated facade system comprises a rainscreen, support framework, and ventilated cavity. The cavity between the cladding and substrate promotes airflow, regulates temperature, and minimizes moisture buildup. This system enhances energy efficiency, protects against weather elements, and reduces noise pollution. It is popular for institutional, commercial, and high-end residential projects due to its longevity, low maintenance, and aesthetic properties.

• Terracotta Louvers:

  Terracotta cladding panels are arranged horizontally or vertically to form an overlapping pattern that resembles shutters. This design controls light and airflow while offering privacy. They can also be positioned at angles to direct sunlight and reduce glare. Beyond their functional advantages, terracotta cladding panels add visual sophistication to a building's exterior with their natural reddish-brown color and texture. They are also durable and weather-resistant, and their ability to diffuse light creates a warm ambiance inside.

• Terracotta Tiles:

  Terracotta facade tiles are available in different sizes, shapes, and surface finishes. They include traditional square or rectangular tiles, hexagonal or octagonal tiles, and decorative mosaic tiles. The tiles have several surface finishes, including smooth, embossed, glazed, and matte. Their earthy reddish-brown color and ability to blend with other materials makes them a popular choice among architects.

• Terracotta Rainscreen:

  A terracotta rainscreen cladding system has a non-load bearing outer wall and a ventilated air space. The outer wall is made of terracotta panels, and the ventilated air space is between the outer wall and the inner wall. This system prevents water from penetrating the inner wall, controls moisture, and improves energy efficiency by reducing heat loss. It is widely used in institutional, commercial, and residential buildings due to its durability and low maintenance.
