Grade determines the visual cosmetic aspects of the floor. It is a popular belief that the option of a single grade rather than the other will determine the durability of the floor -- however, we want to refute this fantasy. It is not true, as the grade of wood only indicates how elegant the wood is and emphasises its unique character. This makes it much easier to select the right floor to match the type of the interior and your tastes.
While durability is dependent upon the character of the flooring, its appropriate maintenance in accordance with the provider's rules and also the suitability of the flooring for the given property.
The grade gifts these natural characteristics of wood as sapwood, heartwood, grain or knots figure. The higher the grade is, the more refined the timber is and the more knots it has etc..
This has also influence on the price of the floor -- the higher the grade, the greater the given floor will cost. The choice of a single grade across the other is a topic of personal tastes and may depend on interior design and, obviously, price-related factors.
We distinguish between four key oak flooring grades. These include:
Prime Grade (aka AB Grade)
The best, and so the most expensive tier is prime standard. Characteristic for this tier is a few knots. Individual boards suit you another as regards their color variation and colour. For that reason, it has quite a uniform and refined appearance, which it simplifies the procedure where the timber is cut. Compared to other ranges, in the event of prime grade, the timber is cut in the center of the log. Thus, prime grade walnut flooring contains hardly any sapwood.
Select Grade (aka ABC Grade)
Going down from prime standard, the boards have a greater number of knots and are diverse in terms
Natural Grade (aka ABCD Grade)
The lower grades have more vivid colour variations between individual floorboards and much more conspicuous knots (30 mm). However, this oak timber flooring tier enjoys great popularity among homeowners since it's quite affordable, and insignificant colour versions make the flooring extremely exceptional. That is the effect that some customers wish to attain.
Rustic Grade (aka CD Grade)
This caliber is often referred to as rural or country look. This sort of flooring has clearly marked knots (35 mm) and important variations between the floorboards concerning their colour. As the lowest tier, rustic is the least expensive grade of all oak grades and thus the hottest one. Clearly visible big knots and large differences in colour between the floorboards create the rustic grade cheaper, but at the same time really unique and different in nature.
