If you have got your mind into wood flooring study style, it is highly probable that you have come throughout the expression quarter sawn hardwood flooring.
As most of us know, timber comes from trees which are cut to be processed into an entire array of raw wood material. If it comes to sawing a timber log, you will find 3 important means of doing this. They are:
– Plain Sawing
– Quarter Sawing
– Rift Sawing
If it comes to wood floors, the choices which are made from quarter sawn wood will have slightly different characteristics to wood flooring made using the other two approaches. In order to clarify those differences, it is important to speak briefly about each different sawing method and then outline what makes quarter sawn hardwood floors different, so that’s what we’ll to do here. To be able to understand the conditions, it is important to visualise the growth rings that radiate out from the centre of a log and the medullary beams that spread out from the center like a sunbeam.
Plain sawn, flat walnut or tangential cut timber is the most commonly sawn type of wood which you’re likely to come across. Considered to be the simplest way of cutting on a plank out of a round log, this way of sawing can run either parallel to or perpendicular to the yearly growth rings of the tree trunk. This means is that when you look at the conclusion of a plank, you will see feature arch shapes of growth rings.
Most frequently, logs have been quartered when quarter sawing is being used, which means that the log is cut into quarters, both across and up and down its length. Thereafter, the boards are cut at 90 degrees from the right end of the consequent quarter. This indicates is that there are varying widths of board created from every quarter, which range from broad to relatively narros. The largest of these boards, which can be called quartered boards and will typically be composed of a first board of about 8″ wide and subsequent boards of around 6.5″ determined by the thickness, reducing into some rift board (see below) of approximately 4.5″. Typically quarter sawn boards possess the growth rings visible at an angle of between 60 and 90 degrees and also the top layer of the board indicates the medullary rays quite definitely.
Rift sawing is the expression used to describe cutting of logs radially into boards so they are cut at ninety degrees into the faces of the log. Effectively this means that the growth rings of the tree appear at right angles to the edges of the consequent boards. This expression is often confused with quarter sawing, but is completely different and can be a more expensive means of producing quality planks than quarter sawing due to the wastage involved. In rift sawn planks, growth rings are at an angle of 30-60 degrees and there is little visibility of medullary rays.
Both key advantages of quarter sawn hardwood floors:
It is more stable than plain sawn flooring. Thanks to the way the boards are cut, quarter sawn boards are somewhat less vulnerable to contraction and expansion as temperature and humidity levels vary. This means is that they are not as likely to build gaps or to endure with cupping after laid.
2. Although quarter sawn flooring is more expensive than plain walnut flooring, it’s cheaper than rift sawn flooring. This is because more planks may be retrieved from each log using this method than rift sawing. Clearly, the more boards that are cut from each log, the lower the depreciation and also the greater the cost.
