The siding rain screen is one of those innovative designs in the exterior wall assembly system that makes use of an air space created between the cladding and the building structure. The primary function of the siding rain screen is to facilitate proper drainage and air circulation to reduce the risk of decay, mold growth, and possible structural damage. For homeowners, the use of a siding rain screen results in increased durability and energy efficiency, and reduced maintenance costs. Moreover, this exterior wall system promotes pressure-equalization behind the siding by eliminating the risks of water penetration during strong rainfall and winds. The continuous airflow through the system ensures that wall assemblies remain dry and stable in different weather conditions.
