Timber cladding is a popular choice for adding warmth and character to both indoor and outdoor spaces, but the materials, treatments, and installation techniques vary depending on its application. Understanding these differences is essential for achieving the best results for your project.
Timber Species, Treatments, and Finishes
Internal timber cladding is typically chosen for its visual appeal and doesn’t require the same level of durability as external cladding. Redwood cladding is popular for interiors due to their light tones and smooth finishes. Cedar cladding is another excellent choice for a more luxurious look. Since internal cladding isn’t exposed to weather, it doesn’t require extensive treatment.

External timber cladding, on the other hand, must withstand harsh environmental conditions, so durability is key. Species like cedar, frake noir timber cladding, and treated softwoods are ideal for outdoor use because they naturally resist decay and pests. External cladding is often treated with preservatives to increase its resistance to moisture, UV damage, and insects. Finishes like weatherproof wood stains and oils are commonly used to maintain its appearance and prolong its lifespan, though some timbers like cedar can be left untreated to weather naturally into a silver-grey patina.
Aesthetic and Functional Recommendations
For interiors, timber cladding is ideal for creating a warm, inviting atmosphere. Matchboard and tongue-and-groove styles work well in living rooms, bedrooms, or even bathrooms when properly sealed. The smooth finish and variety of finishes available make it easy to customise to suit both rustic and modern designs.
Externally, timber cladding is often used on walls, garden buildings, and outbuildings to create a natural, cohesive look. Treated redwood offer an affordable solution, while cedar or frake noir provides a premium, long-lasting finish. When installed and maintained correctly, external cladding not only enhances aesthetics but also offers additional insulation and weather resistance.
Installation Tips
When installing internal cladding, it’s important to prepare the surface by ensuring it’s clean and level. The panels can then be fixed using nails, screws, or adhesive, depending on the surface material. After installation, apply your chosen finish to protect the wood and complete the look.
For external cladding, installation is more technical to protect the structure from weather damage. A weatherproof membrane should be installed beneath the cladding to prevent moisture infiltration, and an air gap must be left behind the cladding for proper ventilation. Rust-resistant fasteners and preservative-treated edges will ensure durability and reduce the risk of decay.
Final Thoughts
Internal and external timber cladding share the same foundational appeal but differ significantly in their requirements and performance. Selecting the right species, treatments, and finishes based on the environment is crucial for a successful project.
