Flooring Grades and
Technical Information and Sizes
Flooring supplied by BTF comes in three different
grades. Some clients assume that, for instance, Prime Oak is better
quality than Country Oak because of the price differential. It is
important to make a distinction between GRADE and QUALITY. All flooring
is of the same quality, this means that regardless of the grade
is has been kiln dried in the same manner, it has been machined
in the same way, it has been acclimatized in the same way and it
has been packed in the same way.
COUNTRY GRADE
– most popular- knots of any size, pips, colour variation,
sap wood are allowed as long as they do not compromise structural
integrity of the floorboard. All boards are supplied with knots
pre filled although, boards with knots open can be produced.
CHARACTER GRADE – second
best seller – Sapwood is allowed on the back of the floorboard.
Healthy knots same colour as the wood are never larger than 20mm
in diameter. Dark knots, again, never larger than 20mm in diameter,
are allowed if pre filled. Straight splits are allowed up to 20mm
in length. Diagonal splits are not allowed. Some variation in colour
is allowed.
PRIME GRADE No
sapwood, dark knots, straight splits, diagonal splits or variation
in colour is allowed. Health knots of no more than 8mm are allowed
only if they are the same colour as the wood.
The only difference between the grades is the Size of the Knots.
