Larch

In larch, the natural grain pattern and colour variation of the wood are clearly visible. In addition to natural knots, larch surfaces also feature oval knots, round knots and knots that have been treated with brown wood cement.

Larch is a valued softwood species. The colour of its heartwood is a reddish brown, while the sapwood is lighter in colour. Larch withstands wear better than pine. Larch is characterised by its significant colour variations and knottiness.

In larch, the natural grain pattern and colour variation of the wood are clearly visible. In addition to natural knots, larch surfaces also feature oval knots, round knots and knots that have been treated with brown wood cement. The colour varies naturally from a light yellowish tone to a reddish colour. The rustic appearance of the wood evens out the variation.

All types of wood can react to excessively dry indoor air. If the relative humidity (Rh) drops below the recommended 35–60%, cracks may appear in the flooring. Therefore, it is important to monitor indoor humidity, especially during dry seasons such as winter, and increase humidity if necessary, for example, with a humidifier. Softwood species (e.g., Pine, Larch, and Douglas fir) are particularly sensitive to dry indoor air and may develop hairline cracks or larger cracks more quickly. The optimal humidity level of 35–60% Rh is also the most suitable indoor humidity level for humans.

Timberwise floors can safely be installed on an underfloor heating system. Douglas fir/Pine/Larch is a softwood tree species. softwood are structurally more sensitive to moisture and dryness fluctuations than hardwoods. Underfloor heating may potentially cause cracks on the surface of a softwood floor. Considering this, softwood floors can still be installed with underfloor heating.
