Grades:
Premium – uniform in appearance and colour flooring. If there are any filled knots or knot holes, they’ll likely be very small and quite faint in colour. Free from sapwood.
Select – contains a few more variations, knots and filled knot holes than premium grade. This flooring is still largely uniform in appearance with moderate colour variation and knots which give it a more natural appearance. Free from sapwood.
Living – contains a few more variations, knots and filled knot holes than premium grade. This flooring is still largely uniform in appearance with moderate colour variation and knots which give it a more natural appearance. Narrow sapwood allowed.
Classic – contains plenty of knots and colour variation. Classic grade flooring sometimes has natural colour filled holes and wood inserts to give smooth appearance. Free from sapwood.
Rustic – most natural looking of all the flooring types. It has the largest range of colour variation and will have plenty of knots, knot holes, wooden inserts and natural grooves – filled in with natural wood filler for a smooth yet rustic appearance. Sapwood allowed.
Optional:
Surface mechanical treatment: medium brushed; deep brushed; fortified; sawmarks
