There are a few deciding factors when it comes to choosing hardwood flooring. One of the factors you may not have considered is the type of cut. Each cut adds its own unique appearance but also changes the performance under various common conditions. There are 4 different cutting options available. The most common among all species is plainsawn. Rift sawn, quarter sawn and live sawn are mostly produced with White Oak.
Plain sawn is the most common cut used for flooring and most hardwood lumber products, also referred to as flatsawn. These boards have end grain with growth rings of
0 – 35 degrees to the surface that produce “cathedral” grain pattern.
The performance of plainsawn flooring typically has the greatest amount of lateral movement across the width of the board during seasonal changes. Depending on species, most ¾” solid hardwood plainsawn flooring move twice as much across the width compared to rift and quarter sawn.
Quarter sawn boards have end grain with growth rings of 60 – 90 degrees to the surface where the medullary rays of the lumber are split during the cutting process causing a unique “fleck” pattern to emerge. This pattern is mostly pronounced in White Oak flooring creating a very unique look.
Rift sawn boards have end grain with growth rings of 45 degrees to the surface, producing a very linear grain pattern. Rift sawn lumber is produced from the outer wedge of the quarter sawing process as the sawyer works his way from the inside to the outside of the wedge.
Rift and quarter sawn flooring typically has the most dimensionally stability as most of the movement is through the thickness of the board. This cut is best solid choice for radiant heat flooring.
Live sawn or “thru cut” lumber contains all three cuts (plainsawn, rift and quarter sawn) and has end grain with growth rings of 0 – 90 degrees to the surface. This cut creates a distinctive stunning look as it contains cathedral, fleck and linear grain patterns in a single board. To get the most apparent look, boards should be at least 6” wide and at Peachey we provide widths up to 16”!
This cut combines the performance characteristics of all three cuts. It’s generally more stable during seasonal changes and shrinks less on average compared to plainsawn due to greater percentage of rift and quarter sawn material in the cut.
