When buying a hardwood floor you will be bombarded by all sorts of terms and phrases related to the appearance of the wood, known as the 'grading rules'. Every species of wood has it's own grading rules so make sure you ask your wood flooring company to provide you with the grading rules for the species of wood you are considering. At Turgon we work mainly with oak and here are our three grades;
Rustic grade is characterised by a mix of both flat cut and quarter cut light oak. Rustic grade will have colour variation and knots up to 35mm in diameter with no more than 5 knots per board. There may also be some additional light healthy knots and pin knots, both single and cats glove, with a diameter up to 5mm. All knots where necessary will be repaired, filled and sanded. Rustic grade will not contain bark pockets, sapwood or worm holes.
When we say our knots are repaired, we mean that large knots are filled with a matching piece of healthy timber and not with ugly filler, this gives the floor a more natural and we think more pleasing look.
Prime grade is characterised by a mix of both flat cut and quarter cut light oak. Prime grade has little or no colour variation but can have knots with a diameter of no more than 5mm and a maximum of 2 knots per board. There may also be some single pin knots. Apart from this prime grade is completely knot free. Knots where necessary will be repaired, filled and sanded. Prime grade contains no bark pockets, sapwood or worm holes.
Quarter sawn grade is characterised by quarter cut light oak only. Quarter sawn grade is knot free and has uniform colour (discoloration not permitted). Quarter sawn grade contains no bark pockets, sapwood or worm holes.
Here are our tips to make sure you get the flooring you expect:
• Don't make your choice of flooring from a small sample, as these can be misleading.
• Ask your supplier to furnish you with the grading rules for their products.
• Visit your wooden flooring supplier's show room to see larger areas of the wood floor.
• Ask to see pictures of installations using the timber you're interested in, and finally...
• Remember wood is a natural material and there will be variation from batch to batch. This is part of its beauty.
