Timber Cladding Detailing
The performance of timber cladding depends on how it is detailed as much as the material itself. Ventilation, fixing, board layout and junction design all influence how the façade behaves over time.
Getting the Detail Right
Timber cladding is a natural material that responds to moisture and temperature. Without proper detailing, this can lead to movement, staining or premature failure.
A well detailed façade allows the timber to perform as intended while maintaining a consistent and controlled appearance over time.
Cladding Principles
• Ventilated cavity behind cladding
• Drainage at base of wall
• Continuous airflow top and bottom
• Correct batten support
• Allowance for timber movement
• Appropriate fixing methods
Typical Cladding Build-Up
Timber cladding is installed as a ventilated rainscreen system. The cladding sits off the structure on battens, creating a cavity that allows air movement and moisture drainage.
This approach protects both the cladding and the underlying structure while supporting consistent long-term performance.
Board Layout & Spacing
Board width, spacing and profile all influence the finished appearance of the façade. Consistent spacing allows for movement while maintaining alignment across elevations.
Layout should be considered early in the design process to ensure a clean and repeatable finish.
Junctions & Edges
Junctions are critical to how the cladding performs. This includes corners, openings, and where the cladding meets other materials such as windows, doors and trims. These areas must be detailed to manage water and maintain airflow behind the boards.
• External corners
• Internal corners
• Window and door reveals
• Base and top details
Fixings & Installation
Fixing method will depend on the selected profile and design intent. Both face-fixed and secret-fixed approaches can be used, provided spacing and alignment are controlled.
Fixings should be suitable for external use and installed to maintain consistency across the façade.
Fire & Compliance
Where fire performance is required, the cladding system should be considered as part of the full wall build-up. Timber, cavity design and fixing approach all influence the final classification.
Project Specific Detail Drawings
Detailed drawings and fixing guidance are provided for active projects. These are developed in line with the selected product, façade design and performance requirements to ensure the cladding system is detailed correctly.
We work with architects and contractors during the design and specification stage to support project delivery.
