Larch Cladding Boards FEATHER EDGE (FE)
Our high-quality cladding boards are crafted from slow-grown larch, making them a popular choice for building renovations and new constructions due to their superior weather resistance. The profile features a concealed installation groove, simplifying the mounting process and providing a seamless aesthetic finish. They are commonly used in residential and commercial projects.

Unique Characteristics of Larch Wood
Larch is renowned for its unique properties:
- Durability: More resistant to cold than metal, with hardwood characteristics and stone-like hardness. Moisture strengthens the wood over time rather than degrading it.
- Natural Resistance: Highly resistant to external elements, decay, and wood pests, making it an exceptional construction material.
Durability
- Larch wood is naturally durable (Class 3 according to BS EN 350-2), making it ideal for outdoor use due to several factors:
- Chemical Composition: Contributes to its high resistance to decay, making it one of the hardest and most durable softwoods.
- Density: High density makes it difficult for decay organisms to penetrate the wood.
- Longevity: With proper detailing and exposure to outdoor elements, larch wood can last between 50 to 100 years.
- Maintenance: Due to its natural longevity, larch wood does not require treatment, with any coatings applied purely for aesthetic reasons.
Density
Larch is an exceptionally dense wood, classified under BS EN 350-2 with an approximate density of 630 kg/m³ at 18% moisture content. This makes it highly resistant to damage, suitable for exposed locations, or areas prone to scratches and dents.
Stability
Our wood products are dried in convection kilns, ensuring even drying and optimal stability. Better dimensional stability can be achieved with narrower boards, such as 120 mm and 95 mm.
Application
These high-quality larch cladding boards are an excellent choice for any construction project, offering durability, aesthetic appeal, and ease of installation. Their natural resistance and longevity make them a sustainable and reliable option for both residential and commercial applications.
