Rainscreen Façade Cladding is a constructed façade system, which consists of a sub frame, or panelised rail system that is cladded with natural stone. The benefit of Rainscreen Cladding is that it will give the appearance of a solid walled structure without having to use mortar joints to bind the sections of stone together.
The cladding support frame is normally aluminium within the cavity and located back to the structure with brackets and primary fixings. Correctly specified, a rainscreen cladding system will provide insulating properties whilst controlling water, wind and fire.
Rainscreen Cladding can be divided into two types:
Pressure-Equalised Rainscreen Cladding – The cavity behind the natural stone panels is divided into area’s to generate a pressure to stop the water from entering the open joints.
Drained and Ventilated Rainscreen Cladding – the open joints between the natural stone panels allows air to move, therefore encouraging the water to dry and evaporate.
The Rainscreen Cladding process has been used for over 40 years and is becoming an evermore popular façade solution for projects within the United Kingdom. Rainscreen Façade Cladding is further enhanced by its adaptability as it is suitable for use on steel and concrete frame buildings whilst being used for both new build and refurbishing pre-existing envelopes.
