The choice of grade determines the floor’s liveliness and number of visible knots.
As a flooring material, oak is hard and durable and a safe choice for almost all kinds of interiors. Considering its weight, oak does not move much and is therefore a popular interior decoration material.
The Select grade is carefully selected, more evenly coloured, and almost knotless. The grade allows the filling of pin knots, the natural reflective pattern of oak, i.e., the pattern created by the medullary rays of the tree, and the colour variation caused by the grain pattern.
Classic is a natural-looking grade in which the natural grain pattern and colour variation of the wood are clearly visible. The natural knottiness of the wood, with a limited size and number of knots, is allowed within the grade. The grade also allows small knot groups, the so-called cat paws, as well as the filling of knots and the natural reflective pattern of oak, i.e., the pattern created by the medullary rays of the tree.
The Vintage grade contains filled cracks and healthy black knots of various sizes. The number of knots, filled knots, and filled cracks varies. Black fillings are part of a genuine vintage look. Small depressions in the filled knots and cracks are also allowed. The grade is characterised by the natural colour variation of oak from light to dark. The general appearance of the Vintage grade is impressive, rough, and rustic.
As a flooring material, ash is hard and durable as well as popular due to its nuanced colour and varying structure. Different surface treatment options give ash character and make it a very trendy flooring material. In addition to residential rooms, ash is also excellently suited for use in public spaces where a unique and strong look is desired.
The Select grade is carefully selected, subdued and almost knotless with an evenly coloured general tone. For this harmonic grade, the natural colour variation caused by the grain pattern, as well as healthy light pit knots are allowed.
The Classic grade is a natural-looking grade in which the wood’s natural grain pattern, color variation and small individual dark knots are clearly visible. The general coloring of Classic is slightly darker than Select. In the Classic grade fillings are allowed.
The Olive grade has been named after the dark heartwood, which is also called ‘olive’. The variation in appearance between different boards may be significant, and part of the boards may be without the dark heartwood. Knots, knot groups and filling of knots is also allowed for this grade.
As a flooring material, larch is significantly harder than other softwood. Its tightly grained look and beautiful, reddish-brown colour are perfectly suited for many locations where a durable flooring with some character is desired. Larch flooring combines an amazing appearance with good wear resistance.
Note! Larch is not recommended for installation with underfloor heating, unless a relative humidity between 40–60 RH can be constantly guaranteed. In drier conditions, cracks may appear in the wood material in question. With this being considered, larch floor can also be installed with underfloor heating.
The Larch Select grade is carefully selected, calm and generally even-colored and almost knot-free. This harmonic grade is allowed to include natural color variation caused by grain pattern as well as healthy, light colored pin knots. Filled knots, as well as knot patches are allowed within the grade.
Larch Natural grade is characterised by knottiness and significant colour variations. The colour of larch naturally varies from a light yellowish tone to a reddish colour. Filled knots, as well as round knot patches and oval patches are allowed within the grade.
In the Vintage grade wood’s natural grain pattern, significant colour variations, and – in addition to natural knots – knots and cracks that are filled with dark filler, as well as round knot patches and oval patches, are allowed for the grade. The colour varies naturally from a light yellowish tone to a reddish colour, and the rustic appearance of the grade evens out the variation.
