Frequently Asked Questions
What exactly is a rainscreen cladding system?
A rainscreen cladding system is a multi-layered exterior wall assembly made up of an outer cladding layer, an air gap, and an inner layer. The air gap creates a buffer between the cladding and the wall so moisture can drain away and air can circulate freely. This design controls moisture, prevents water infiltration, and improves energy efficiency compared to traditional cladding.
How does the air gap in a rainscreen system actually work?
The gap or cavity between the cladding and the building structure acts as a drainage plane. Any moisture that gets past the outer cladding layer is redirected downward and expelled through weep holes at the bottom of the wall. That same air gap also allows natural ventilation, which helps regulate temperature and control humidity inside the building envelope.
Will a rainscreen system help lower my energy bills in the Sacramento area?
Yes. The air gap acts as an insulating layer that reduces thermal bridging and minimizes heat loss and gain, which is valuable in Northern California's hot summers and cool winters. This lets your heating and cooling systems work less, lowering energy consumption and keeping indoor temperatures more stable. Many Sacramento and Bay Area homeowners see improved comfort along with reduced energy demand.
Does rainscreen cladding really prevent moisture and dry rot problems?
It is one of its biggest advantages. By allowing water that infiltrates the outer layer to drain away through the air gap, rainscreen cladding controls moisture accumulation before it can damage building materials. This helps prevent structural damage, mold growth, and dry rot while protecting indoor air quality. Managing moisture this way is key to the long-term durability of the structure.
Can rainscreen cladding be used on any type of home or building?
Rainscreen cladding systems can be adapted to a wide range of building types, including residential, commercial, and institutional structures.
