No, larch cladding does not necessarily need treatment. Both European and Siberian Larch are naturally resistant to rot, decay, and insects due to their high resin content and low moisture movement. This makes them highly durable for outdoor use like cladding.
However, there are some factors to consider:
- Desired aesthetic: While untreated larch will naturally turn a silver-grey color over time, some prefer to maintain the reddish hue. Treatment can slow down this process and maintain a warmer tone.
- Local conditions: If your location experiences extreme weather conditions, treatment might offer additional protection from moisture and UV damage, potentially extending the lifespan of your cladding.
- Maintenance preferences: Treatment can simplify maintenance, potentially requiring less cleaning and reapplication compared to untreated larch.
Therefore, treatment is optional but can offer benefits depending on your specific needs. Consult with a professional familiar with your local conditions and desired aesthetics for personalized advice.
