Larch cladding is a fantastic option for those looking to create a natural, durable, and attractive finish on a building’s exterior. Known for its resistance to weather and natural decay, larch cladding is suitable for various climates and adds significant visual appeal. However, installing larch cladding requires a thoughtful approach to ensure longevity and performance. In this guide, we’ll walk you through the essential steps to prepare, install, and maintain larch cladding effectively.
Why Choose Larch Cladding?
Before starting the installation process, it’s worth understanding why larch cladding is such a popular choice for homeowners and builders:
Durability
Larch is naturally dense, making it more resistant to wear, tear, and impact than other woods. It’s highly resistant to rot, decay, and insects, which are crucial factors for outdoor applications. This durability makes larch a reliable material that can withstand harsh weather conditions, from heavy rains to intense sun exposure.
Natural Aesthetic
Larch wood has a warm, inviting appearance with hues ranging from golden yellows to deep reddish-browns. Its straight grain and occasional knots give it character, enhancing the architectural appeal of both traditional and modern buildings. Over time, untreated larch will weather to a beautiful silver-grey patina, adding to its charm.
Environmental Sustainability
When sourced from FSC® (FSC-C134890) certified forests, larch is a sustainable choice. It’s renewable and has a lower carbon footprint compared to non-renewable materials. Using sustainably sourced larch supports responsible forestry practices, which help protect biodiversity and reduce environmental impact.
Preparing for Installation
Preparation is key to a successful installation that will stand the test of time. Let’s go over the steps to ensure you’re ready for the process.
1. Check Local Building Regulations
Before you begin, consult with local authorities to make sure your cladding project complies with building regulations. In certain areas, specific fire resistance ratings and other safety standards may be required, particularly for exterior cladding.
2. Gather Essential Tools and Materials
Ensure you have all the tools and materials ready before you start the installation. You’ll need:
- Larch cladding boards (pre-treated if required for extra protection)
- Battens (treated timber for long-lasting durability)
- Breathable membrane or weatherproof underlay
- Stainless steel nails or screws to prevent corrosion
- Saw, level, drill, and nail gun
- Measuring tape, pencil, and chalk line for accurate measurements
3. Prepare the Wall Surface
The wall surface where the cladding will be installed should be clean, dry, and in good condition. Install a breathable membrane or weatherproof underlay over the wall to add a layer of moisture protection. This underlay prevents water infiltration and helps extend the life of your cladding by ensuring moisture is directed away from the wall.
Step-by-Step Installation of Larch Cladding
Once your materials are prepared, you’re ready to begin the installation process. Follow these steps carefully for a successful result:
1. Install the Battens
Battens provide the framework on which the cladding will be fixed and allow for essential ventilation. Secure horizontal battens to the wall at intervals of 400-600mm, depending on the board width. These spaces ensure a healthy airflow behind the cladding, helping to prevent moisture build-up that could lead to rot or warping.
Ensure the battens are level and secure, using stainless steel screws or nails to prevent corrosion. This step is essential to keep the battens stable, which directly affects the alignment and durability of the cladding boards.
2. Begin from the Bottom Up
Start cladding from the base of the wall, working upwards. Starting at the bottom allows for a natural overlap and ensures water can run off properly. For the first row, place the boards horizontally with a slight overhang to direct water away from the structure’s foundation.
Use a level to make sure the first row is completely straight. Attach the boards securely to the battens using stainless steel nails or screws, which prevent rust and add longevity to the structure.
3. Maintain Consistent Gaps
To allow for natural expansion and contraction, leave a small gap between each board, typically between 2-5mm. This spacing is essential to accommodate changes in the wood due to temperature and humidity variations. Using a spacer tool can help keep the gaps consistent, resulting in a polished finish.
4. Stagger the Boards
For a professional look and added stability, stagger the boards in a brickwork pattern. This layout reduces the chance of alignment issues and ensures the cladding’s structural integrity. Staggered joints are less prone to water infiltration and create a visually appealing result.
5. Trim and Fit Around Openings
When you reach windows, doors, or other structural openings, measure and cut the boards carefully to fit around these areas. Leave a small gap (a few millimetres) around the openings to allow for expansion and to ensure water drainage.
You may want to install flashing above windows and doors to direct water away from these vulnerable areas. Flashing can help prevent moisture damage, particularly around areas where water tends to accumulate.
6. Add Finishing Touches and Trim
Once you’ve clad the entire wall, add corner trims, edges, and any final detailing to complete the finished look. Corner trims help protect edges and cover any visible joints. They also provide an extra layer of moisture protection, giving the cladding a refined, completed appearance.
Caring for Larch Cladding
Larch cladding is low-maintenance, but regular care can significantly extend its lifespan and maintain its natural beauty. Here are a few tips:
- Clean Regularly: Remove dust, debris, and any mildew with a soft brush. Avoid power washing, as it can damage the surface of the wood. Simple cleaning prevents dirt build-up, which could lead to discolouration over time.
- Reapply Protective Treatments: If you’d like to retain the original golden tones of the wood, consider applying a UV-protective oil every few years. This helps protect against sun exposure, which can cause the wood to grey over time. However, many people appreciate the natural silvering process, which doesn’t require any treatment.
- Annual Inspections: Check for signs of damage, such as loose boards or cracks, especially after extreme weather. Address any issues promptly to maintain the cladding’s structural integrity and aesthetic appeal.
