PRINCIPLES OF A VENTILATED RAINSCREEN SYSTEM
THREE RAINSCREEN PRINCIPLES:
• First Line of Defence
- Reduces the moisture load on cladding
- Minimise rainwater passage into the wall
• Second Line of Defence
- Intercept water
- flashed, drained, vented air cavity + water-resistant membrane
• Air Barrier System – Ventilation Effect
- Reduces the static air-pressure difference across the cladding, creating a “chimney effect.”

SUMMER
• 80% heating flux reduction from sun radiation
• Promotes the thermal exchange of air
• Offers performance that is equivalent to a facade protected by shadows
