Siberian Larch’s impressive density can be attributed to the place in which it grows. Siberian Larch grows in an environment that is known for its long, harsh winters and therefore the growing seasons are short. As a result of the short growing seasons, it is composed on average of 40% latewood which is considered to be significant. Latewood is denser and mechanically stronger than the opposing earlywood. Therefore, these higher levels of latewood create a floor with impressive wear resistant characteristics.
Over time, earlywood wears out leaving the harder latewood as the actual walking surface. Look at any antique floor and this is what you will find. Having a floor with high concentrations of latewood will provide a homeowner with a smoother, more even surface in the future.
