Stone cladding is durable, fire-resistant, and requires minimal maintenance. However, it can be more expensive and heavier than other cladding materials. Thin stone veneers are also available, which offer the aesthetic of natural stone with reduced weight and cost. Stone cladding adds a sense of permanence and sophistication to architectural designs.

Rainscreen Cladding Installation Process

The installation of rainscreen cladding involves several steps. Proper installation is crucial to ensure the system performs as intended. Here's an overview of the installation process:

Preparation

Before installation, the building's exterior walls must be prepared. This includes cleaning the surface, repairing any damage, and ensuring it is level. A support frame is then attached to the wall to provide a base for the cladding. The support frame must be properly aligned and securely fastened to ensure the cladding is installed correctly.

Insulation

Next, insulation is installed on the exterior wall. Insulation helps to regulate the building's temperature and reduce energy consumption. It is important to choose the right type and thickness of insulation to achieve the desired performance. The insulation must be installed tightly against the wall to prevent air gaps and thermal bridging.

Cladding Installation

The cladding panels are then attached to the support frame. The panels are typically installed with a gap between them to allow for ventilation. The method of attachment depends on the type of cladding and the manufacturer's recommendations. It is important to follow the installation instructions carefully to ensure the cladding is properly secured and aligned.

Sealing and Finishing

Finally, the cladding is sealed to prevent water from penetrating the system. Sealants are applied to all joints and connections to create a waterproof barrier.
