RAINSCREEN FAÇADE SYSTEMS
RAINSCREEN FAÇADE SYSTEMS

With new or existing timber, SFS or masonry walls

APPLICATION OVERVIEW

Rainscreen façade systems are lightweight when compared to brick and masonry solutions and can provide the designer with a wide range of aesthetic options.

In addition to thermal performance, fire performance of insulation materials is a crucial consideration, particularly when designing buildings over 18m in height or when the building is to have high occupancy levels or be used by vulnerable occupants.
