What is Larch Wood?
Larch is the conifers of the genus Larix of the pine family Pinaceae. There are 10 to 12 species of larch. They are native to the northern hemisphere, where the temperature is low. Larches are deciduous trees that lose their short needles in autumn.
Larch wood is known to have tough, waterproof, and durable qualities. Mostly used for boats, gazebos, siding, floor, fencing, etc.
Even after being a softwood, It has the properties of natural rot resistance. So almost every species of Larch is compatible with interior and exterior purposes.
|Tree||20 to 45 m (65 to 150 ft) tall, .6-1 m (2-3 ft ) trunk diameter|
|Rot resistance||Resistant to rot|
|Color/Appearance||Pale creamy white|
|Uses||Floors, siding, boats, etc|
What is Larch Wood Used For?
Latch wood is an attractive, durable, and inexpensive flooring option. Being softwood, it can be easily installed, and due to the light color (yellow to a medium reddish-brown), and can be stained easily.
Wood must have rot and water-resistant properties to make good and durable flooring. All these properties are naturally present in larch wood. So we don’t need any extra treatment.
But to preserve the beauty and natural grain pattern of the floor, do stain or polish and take care regularly.
Siding is used for building to protect the building from the elements. In the outer walls, it withstands constant rain, sun, and dust. In this case, the wood should be strong, durable, and high density.
Siberian Larch is widely used to make decking and siding throughout the entire European continent.
Due to its high density and an oily surface, moisture cannot penetrate inside the wood. Therefore it is the preferred wood for making decks, siding, and other outdoor applications.
Larch is great for making hull planks because of the long straight wood veins. Larch is much stronger and more durable than many softwoods. Due to its lightness and better-bending properties, It is a better wood for making boats and boat parts.
The appearance of Larch Lumber
Larch wood is reddish-brown to pale creamy white. It has a clear dark striped or grainy patterning. Its pattern can be easily seen. Sapwood is lighter or nearby white in comparison to heartwood. All species of larch wood have small knots.
Larch Wood Advantages and Disadvantages
- Appearance: It has a great medium reddish-brown to light beautiful appearance.
- Easy to stain: Due to the light color, it can be stained easily.
- Rot Resistant: Moderately durable regarding decay resistance.
- Workability: Due to low density, it can be easily worked with hand tools and machines. Sometimes the work can be difficult due to the spiraled grain pattern and knots. But glues and finishes well.
- Small knots: Knots are common but are usually small.
- More options: We get the option of many colors and grain patterns in larch.
- Insect Resistant: The larch wood has natural insect-resistant properties.
- Stability: Shrinkage in drying is fairly low.
- Drying: The wood dries fairly easily, with some warp and checking.
- Allergies and Toxicity: Larch has been reported to cause skin irritation, as well as hives and skin lesions.
- Odor: European Larch can have a distinct resinous odor when being worked.
- Price: It can be expensive compared to some softwoods like spruce.
Types of larch wood
Western Larch Wood
Western Larch is a famous species of Larch. Its heartwood is yellow to reddish-brown and narrow sapwood is yellowish-white, sapwood is clearly demarcated from the heartwood.
Western Larch wood has straight grain and texture is medium to coarse with a greasy or oily feel. The wood is tough and durable, but it can be bent easily. It is suitable for indoor and outdoor uses.
It is moderately durable regarding decay resistance. So no need to take much care.

European Larch Wood
European Larch is another famous species of Larch. Its heartwood is yellow to reddish-brown and the narrow sapwood is close white and is clearly demarcated from the heartwood.
Generally, European Larch has a straight grain. It contains natural oil, which makes the surface look oily.
The wood is tough, durable, and decay-resistant. Hence it is used for exterior and interior applications.
Being soft and low density, Easily worked with hand tools and machines and can also be easily bent. Lumps are common but usually small.

Japanese Larch Wood
Japanese Larch is native to Japan. Its heartwood is yellow to a reddish-brown and the sapwood is nearly white. Sapwood is clearly demarcated from Heartwood.
Japanese Larch has a straight grain and medium texture. The surface is oily due to the presence of natural oil. Due to this natural oil, it is moderate rot resistant. So it can be used for exterior and interior applications with low maintenance.
The workability of Japanese Larch is very good. Most hand and machine operations produce good results. sanding can create dips and uneven surfaces. Glues and finishes well.

Siberian Larch Wood
Siberian larch is commonly known as Russian larch. Its heartwood is yellow-brown to brown and sapwood is close to white. It is a coniferous tree, so The male and female cones are borne separately on the same tree.
Like other larch species, its grain is also straight. Sometimes there may be irregular grain.
The density of Siberian larch is higher than other larch species. Therefore it can be a little difficult to work with small hand tools.

Tamarack, commonly known as the Eastern Larch, Black Larch, Red Larch, or American Larch. The length of the Tamarack tree is not very long.
The heartwood is yellow to a medium orangish-brown and the sapwood is nearly white and is clearly demarcated from the heartwood. It has a straight grain with a fine texture. It contains natural oil, which makes the surface look oily.
Tamarack is Moderately durable regarding decay resistance. Therefore it is useful for interior and exterior use.
Due to the low density, it is easy to work with hand tools and machine operations.
