In a rainscreen, the cladding which forms the front face of the facade may have open or partially sealed joints with an air space behind. The purpose of this is to form a drained and ventilated space to deal with any water that may get past the cladding. Behind this space is the insulation and then a final air and water barrier in the form of a damp proof membrane over the structural wall. It is good at keeping water out of buildings provided interfaces are properly designed and constructed.This form of cladding construction is now used widely across the UK and we have all the specialist expertise required to carry out the design and detailing for rainscreen cladding schemes, including structural engineering design.
Patrick Ryan Associates has also been involved in the design of new rainscreen cladding systems and bespoke systems on projects.
