Rainscreen cladding refers to exterior siding or panel products specifically manufactured or installed to function within a ventilated rain screen wall system, often incorporating built-in spacing features, drainage channels, or specific installation methods designed to create and maintain the necessary air gap.
Some cladding products are engineered from the outset with rain screen principles in mind, featuring integrated spacers or profiles that automatically create the required ventilation gap during standard installation without needing separate furring strips.
This purpose-built approach simplifies achieving proper rain screen performance compared to retrofitting the concept onto siding products not originally designed with this ventilated system in mind.
What Does Rainscreen Cladding Involve?
- Cladding products engineered with rain screen principles
- Integrated spacing features or separate furring strips
- Drainage and ventilation openings at top and bottom
- Compatibility with the underlying water-resistive barrier system
Why Is Rainscreen Cladding Important?
By incorporating rain screen functionality directly into the product design, rainscreen cladding simplifies achieving this proven, moisture-resistant wall assembly approach, making the performance benefits more accessible without necessarily requiring extensive additional detailing or specialized installer knowledge beyond following the manufacturer’s specific instructions. This built-in approach has expanded rain screen adoption beyond projects specifically designed by building science specialists.
Regions with particularly high rainfall or significant wind-driven rain exposure benefit most from rainscreen cladding’s improved drainage and drying capability, making this an especially worthwhile consideration for coastal, mountain, or other consistently wet climate zones. This regional suitability makes rainscreen cladding a worthwhile consideration for homes facing significant weather exposure. This regional fit makes it an especially smart choice in wetter parts of the country.
Rainscreen Cladding vs. Rain Screen
Rainscreen cladding refers to specific products engineered for this ventilated system. Rain screen is the broader design principle and overall wall assembly concept, which rainscreen cladding products are specifically designed to work within.
