We know wood

Parquet’s multiple shapes and sizes allow for enjoying a coating with countless properties. This also creates exclusive spaces that combine performance and beauty. In its vast range of essences, colors, and finishes, parquet becomes an integral part of living comfortably. At the same time, a design that can enrich spaces offers a pleasant warmth.
A wooden floor, resulting from the processing of a natural essence, will therefore always be unique and unrepeatable. It is not a simple finish. Rather, its nuances and its veins provide for an extremely characterizing piece of furniture.

Wood: a living material

Wood is a natural material that adds warmth to spaces. At the same time, however, it is a living material that interacts with its surrounding environment. Because of this, it may undergo variations over time. The leading factors for color changes are light and exposure to air.
Wood is a natural and, therefore, inhomogeneous material: even two elements of the same wood can never be identical.

Oxidation of wood

The newly produced wooden floor has a different colour than it will after some time, for the effect of oxidation that is a completely natural phenomenon occurring due to exposure of the parquet to light. Wood is a photosensitive material, for this it suffers the natural colour variation process following exposure to air and light, in particular due to the action of ultraviolet rays; this variation occurs mainly in the early periods of exposure to light.

Depending on the wood species, the oxidation will be more or less evident; normally the woods tend to darken, except Teak and Thermo Oak that become lighter. For this reason, the new supply material can be different in tone than the sample viewed by the customer.

Finishes with reagents

The finishes with reagents, smoked and steamed are realized with reaction processes that interact directly with the tannin of the wood, enhancing the naturalness of the material. Consequently, given the characteristic of the reaction process used, the material just worked displays differently from the samples viewable at the showrooms, and already exposed for several months. However, we can ensure that in the space of a few months the maturation of the reaction process will lead to a change in tone.
The peculiarities and characteristics of the finishes obtained by reaction should be enhanced and explained under negotiation, being the result of a natural material and not of a tint. It must be accepted that it may present variegated tone differences and shade variations from lot to lot.

Wood is a natural material, characterized by differences in color or grain, which make the elements different from each other. Due to the exposure to air and light, wood change its surface color over time. In Oak wood, some elements may have shiny streaks called “mirrors”. In others wood species, such as Doussie, Iroko, Merbau, Wenge, mineral concretions can be presented with colors varying from whitish to lemon yellow depending on the chemical nature of the concretion itself. These characteristics, due to the natural variability of the wood, can also be transferred to surface processing in terms of different absorption of the finish / color. For all these reasons, therefore, the correspondence between the supply and the reference sample viewed is to be considered purely indicative. All the wood species proposed by Alma by Giorio have such hardness to guarantee the performance for flooring use; nevertheless the parquet can be dented due to bumps or falls of objects and for the application of concentrated loads on small surfaces. The eventual surface treatment applied to the wooden floor (paint, oil or wax) while carrying out a protective action, does not prevent the above described.
