Stucco Lite Rainscreen combines the simplicity of direct applied cladding system with drainage and rainscreen features. Succo lite rainscreen consists of a nail sealable water resistive barrier over the substrate furring to create a drainage cavity and a cement board sheathing coated with a flexible basecoat reinforced with fiberglass mesh throughout to create a code compliant rainscreen drainage cladding system. 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.
- Improved traditional cladding system
- Positive drainage - rainscreen
- Non-combustible
- High impact resistance
- Cost effective cladding system if no continuous insulation is required
Stucco Lite 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 where spatial separation issues require non combustible cladding, typical of residential dwellings with side setbacks less than 600 mm from the property line.
