There is an understandable level of caution around the specification and design of rainscreen systems.
Correct design and site quality assurance is vital to ensure that the building not only looks right but will perform correctly. Factors considered include thermal calculations; structural calculations (including movement); product fire ratings; fixing specifications; site pull-outs; airtightness, ventilation, drainage and other factors.
Many of the clients that regularly work with A2O will engage our services early in the design process to have a positive influence on the building structure and interfaces with other finishes. This enables our team to optimise the design and fulfil the architect’s design intent.
Brick facades are making a comeback with architects! The use of a brick slip rainscreen has many benefits over traditionally laid brickwork including speed of install; no requirement for lintels; flexibility and the option of installation from MEWPs.
