What is Larch Wood?
Larch wood comes from the coniferous trees of the genus Larix, which belong to the pine family (Pinaceae). There are between 10 to 12 species of larch, all native to the colder regions of the Northern Hemisphere. Unlike most conifers, which are evergreen, larch trees are deciduous, meaning they lose their needles in autumn.
Larch wood is widely recognized for its durability, toughness, and water-resistant properties. It’s often used in applications where these characteristics are essential, such as boats, gazebos, siding, flooring, and fencing.
Although classified as a softwood, larch wood boasts a natural resistance to rot, making it suitable for both interior and exterior projects.

What is Larch Wood Used For?
1. Flooring
Larch wood is an attractive, durable, and cost-effective option for flooring. Its light color, which ranges from yellow to medium reddish-brown, makes it easy to stain and customize to your desired aesthetic. Despite being a softwood, it offers excellent resistance to both water and rot, making it a great choice for high-traffic areas.
To preserve the natural grain and beauty of larch flooring, regular maintenance, such as staining and polishing, is recommended.
2. Siding
Larch wood is widely used for building siding, particularly in regions where buildings are exposed to harsh weather conditions. Its high density and oily surface prevent moisture from penetrating, which helps protect homes from rain, snow, and sun damage.
Siberian Larch, in particular, is a popular choice across Europe for both siding and decking due to its strength and weather resistance.
3. Boat Construction
Thanks to its long, straight wood veins and excellent bending properties, larch wood is a preferred material for boatbuilding. It’s lighter than many other woods but strong enough to withstand the wear and tear of water exposure. Its resistance to rot and moisture further adds to its appeal for crafting hull planks and other boat parts.
The appearance of Larch Lumber
Larch wood varies in color from pale creamy white to reddish-brown, with a distinct dark-striped or grainy pattern. The sapwood is typically lighter, almost white, compared to the heartwood. The natural grain patterns of larch are highly visible and often enhanced by small knots, which give the wood a unique and rustic aesthetic.
