Wood species and grades

Timberwise parquets are made of traceable, ethical and ecological wood. We use do not use exotic or endangered wood species. Below you can find more information about our different wood species and their qualities. We recommend that you read the detailed grade guide dowloaded below, in which the qualities are better introduced with examples.

Oak

Quercus Robur

Hard and heavy wood species
Brinell hardness 2.9–4.1 HB

BASIC DATA

Species description and appearance

There are approx. 200–300 different species of oak in the world. An oak grows to 30 metres and for up to 300 years. Oak is a hard, heavy and strong, as well as a fairly straight-grained tree. It is warm brown in colour. The sapwood and heartwood are clearly distinguishable. The colour of heartwood darkens with age. The reflective patterns caused by the medullary rays are a hallmark of oak’s appearance.

Oak as a Flooring Material

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.

Areas of Use

Private spaces: Living rooms, bedrooms, kitchens and corridors

Public spaces: Restaurants, hotels, offices and entrance halls

OAK SELECT

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.

OAK CLASSIC

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.

OAK VINTAGE

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.

TECHNICAL DATA

PRODUCT MEASUREMENTS

Length = 2180 mm
(also lengths 2,080, 2,000 and 1,818 mm are allowed)
Width = 150, 185, 230 and 270 mm
Thickness = approx. 14,5 mm

STANDARDS AND EMISSIONS

The technical measurements of the product meet the requirements of the European standards set for parquets (EN 13489:2017). The formaldehyde emission is one tenth of the M1 emission classification (test result report VTT2643/00). Timberwise parquet meets globally the industry’s most stringent formaldehyde requirement: JAS ****(MLIT Paragraph 68-25).

TREATMENT OPTIONS AND SURFACE TREATMENTS

Oak is available with both a sanded and brushed surface, and its colour selection is the widest in Timberwise. Oak can be treated with a clear satin, matte or tinted wax oil. The lacquer options are satin and matte lacquers. Oak is also available as untreated, meaning that the customer can apply the preferred treatment on the spot.

Ash

Fraxinus excelsior

Hard and heavy wood species
Brinell hardness 3.2–4.7 HB

BASIC DATA

Species Description and Appearance

Ash is considered a hardwood deciduous tree. It grows in humid areas of Europe, Caucasia and Asia Minor. The heartwood and sapwood are clearly distinguishable. The sapwood is thick and almost white. With age, a clear heartwood formation is created, and it is sharply distinguished as grey, brownish or olive-coloured. The timber is unevenly patterned by different tones, veined or striped, and appears very decorative for that reason. The wood is resilient, heavy and hard.

Ash as a Flooring Material

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.

Areas of Use

Private spaces: Living rooms, bedrooms, kitchens and corridors

Public spaces: Restaurants, hotels, offices and entrance halls

ASH SELECT

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.

ASH CLASSIC

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.

ASH OLIVE

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.

LARCH

Larix sibirica

Strong colour variation and knottiness
Brinell hardness 2.2–3.0 HB

BASIC DATA

Species Description and Appearance

Larch is a valued softwood species. The colour of its heartwood is reddish brown. The sapwood is light-coloured. The timber is characterised by the strongly developed heartwood and summerwood parts. One of the central characteristics of this wood species is its better wear resistance compared with other softwood species. It is also more sensitive to variations in humidity and dryness than hardwood. The wood is very rot-resistant and resilient.

Larch as a Flooring Material

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. 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.

Areas of Use

Private spaces: Living rooms, bedrooms and less-used rooms

Public spaces: Less-used rooms, galleries, museums and spaces not sensitive to wear

LARCH SELECT

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.

NOTE! Larch is characterised by its knottiness and significant colour variations. The colour of larch naturally varies from a light yellowish to a reddish colour. The tone does not change evenly over time throughout the floor, but the difference in tone between the different boards can be very strong. Indoor air that is too dry may create hairline or other types of cracks on the surface of the product, but such cracks usually closes with moisture over the time.

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.

LARCH NATURAL

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.
