Slate Rainscreen Cladding

Posted on  by admin

Welsh Slate’s unique natural properties make it an ideal cladding material for both commercial and high-end residential projects.

Its a non-porous metamorphic rock which is exceptionally uniform, inert and non-combustible. These properties make it extremely resistant to weathering and chemical attack and its negligible water absorption protects it from frost.

The laminate structure of Welsh Slate gives it strength and stability allowing it to be used down to 20mm thickness when utilising Welsh Slate’s Rain-Screen façade system. Available in Honed, Riven, Textured and Sawn finishes in both Penrhyn Heather and Cwt-y-Bugail Dark Blue Grey colours.

A typical rainscreen cladding consists of a non-load-bearing external cladding material, a ventilated cavity, vapour barrier and an inner leaf. Cladding material, fixed to a supporting metal grid, protects a building’s structure from water and features a ventilated cavity behind.

Joints are left open, which equalises pressure in the rainscreen cavity. With the pressure equalised within the system, water is not drawn into the cavity.

Regular spaced drips are placed within the system to aid drainage of water from behind the facade. Spacing the drips will depend on the system design for any individual project.
