Stucco Wall Rainscreen is a traditional hard coat stucco system, consisting of polymer modified cement palster reinforced with galvanized metal lath, inclusive of a furring system to create a code compliant rainscreen drainage medium. The finish texture can be selected from any of the available Durex® Architectural Coatings. The cladding system is rated non-combustible cladding meeting the building code requirements for non-combustible construction.
- Traditional cladding system
- Positive drainage - rainscreen
- Non-combustible
- High impact resistance
Succo Wall Rainscreen is suitable for use over a wide range of structurally sound substrates. It is best suited for substrates designed with a deflection ratio lower than L/360.
