The Beauty and Benefits of Timber Cladding
Timber cladding is a favoured choice for enhancing Australian home exteriors, offering a unique blend of natural beauty, warmth, and character. Beyond aesthetics, it contributes to sustainability and can improve thermal performance. LB Timber supplies premium Australian hardwoods—Ironbark, Blackbutt, Spotted Gum, and Tallowwood—ideal for creating stunning, durable, and environmentally conscious facades. This guide covers planning, installation, and maintenance for timber cladding projects.

Timber cladding offers significant advantages
- Aesthetic Versatility: Its natural beauty suits diverse architectural styles, from contemporary to traditional.
- Environmental Benefits: Sustainably sourced timber is renewable, has lower embodied energy, and stores carbon.
- Insulation: Wood's natural insulating properties can improve energy efficiency.
- Durability: Australian hardwoods, correctly chosen and maintained, offer long service life.
Planning Your Timber Cladding Project
Careful planning ensures the project meets aesthetic, budget, and performance goals.
Design Considerations: Decide on orientation (horizontal for a traditional look, vertical for a more contemporary feel ). Explore styles like Shou Sugi Ban (charred timber), timber battens for clean lines, or mixing timber with materials like stone or metal.
Timber Selection
Choose a species based on natural durability (AS 5604 Class 1 or 2 for exposed use ), weather/insect resistance, and BAL rating.
Type of hardwood | Charactoristics |
---|---|
Ironbark |
Exceptional durability, high BAL rating |
Blackbutt |
Good fire resistance (BAL-29), attractive pale tones |
Spotted Gum |
Striking appearance, durable, BAL-29 |
Tallowwood | Excellent moisture resistance, BAL-19 (untreated) |

Cladding Profiles
Common profiles include Shiplap (overlapping, shadow lines), Tongue and Groove (T&G, tight fit), and Weatherboards (traditional overlap).
Compliance
Check BAL rating requirements (AS 3959) if in a bushfire-prone area, and NCC fire resistance requirements. Always consult the local council for permit needs. Calculate timber quantity accurately, including 5-15% for wastage.
Timber Cladding Installation Best Practices
Correct installation is vital for performance and longevity.
Substructure
A waterproof, breathable sarking (building wrap) should be fixed to the building frame. Then, fix timber battens (typically 9mm-20mm+ thick) over the sarking to create a ventilation cavity. This cavity is crucial for allowing moisture to escape and improving cladding stability.
Fixing
Use high-quality, non-corrosive fasteners (stainless steel or hot-dipped galvanized ), ensuring sufficient penetration. Pre-drill hardwoods. Fixings must allow for natural timber movement.
Detailing
Install appropriate flashings around openings and junctions. Crucially, seal all cut ends of cladding boards with a water-repellent preservative before installation to prevent moisture absorption. Acclimatise cladding boards to site conditions before installation.
Finishing and Maintaining Your Timber Cladding
A protective finish enhances appearance and extends service life.
Surface Preparation: Ensure timber is clean, dry, and smooth.
Finish Options:
- Oils/Stains (Penetrating/Semi-Transparent): Enhance natural grain, protect from moisture/UV. Reapply every 1-5 years.
- Paints (Opaque): Offer excellent protection. Light colours are often best. Prime well. Can last 5-10+ years.
- Unfinished (Natural Weathering): Some durable hardwoods can grey naturally. Offers less protection; regular cleaning is important.
Always follow the finish manufacturer’s application instructions.
Maintenance
Regularly clean cladding (annually/biannually) with a soft brush and mild detergent to remove dirt and prevent mould. Inspect periodically for damage or wear, addressing issues promptly. Recoating frequency depends on the finish, timber, and exposure.
