Cuts of Wood

Plainsawn

Plainsawn
This method of cutting produces the widest boards and is the most economical. The wood expands and contracts more with moisture and temperature changes. Not recommended over radiant heating.

Quartersawn

Quartersawn
The logs are cut in quarters and then the boards are cut at 90° to the growth rings. This produces tight clean vertical grain with "fleck" pattern. More stable floor since the wood contracts and expands vertically.

Riftsawn

Riftsawn
Similar advantages as quartersawn. It does not have the fleck patterns that are characteristic of quartersawn wood.

Quartersawn/Riftsawn

Quartersawn / Riftsawn
Includes both types of cuts (see profiles above). This option is more economical than riftsawn only or quartersawn only.
