As a homeowner or builder, you’ve probably heard the term “rain screen” used when discussing exterior finishes for buildings. But what exactly is a rain screen, and what purpose does it serve?
Put simply, a rain screen is a system designed to protect a building from moisture intrusion. It does this by creating a gap between the exterior cladding (the material that covers the building’s exterior walls) and the structural wall. This gap allows air to circulate behind the cladding, which helps to keep the building’s interior dry by allowing any moisture that penetrates the cladding to evaporate.
In addition to preventing moisture intrusion, rain screens can also help to regulate temperature and reduce energy costs. By allowing air to circulate behind the cladding, rain screens can help to prevent heat buildup and reduce the load on a building’s HVAC system. This can be particularly beneficial in hot, humid climates where energy costs can be significant.
There are two main types of rain screens: drained and vented. Drained rain screens are designed to allow moisture to drain out of the gap between the cladding and the structural wall. This is typically achieved by incorporating weep holes or channels into the system that allow water to flow down and out of the building. Vented rain screens, on the other hand, are designed to allow air to circulate behind the cladding. This can be achieved by incorporating vents or other openings into the system that allow air to flow in and out of the gap.
When designing a rain screen system, there are a few key factors to consider. These include the type of cladding being used, the climate and environmental conditions in the building’s location, and the overall design of the building. Different types of cladding may require different types of rain screen systems, and different environmental conditions may require different levels of moisture protection.
