Engineered hardwood produced this way tends to have fewer problems with "face checking", and also does not have the same plywood appearance in the grain. The veneers do not go through the same manufacturing process as rotary peeled veneers. However, instead of being sliced in a rotary fashion, with this technique the wood is sliced from the log in much the same manner that lumber is sawn from a log – straight through. This process begins with the same treatment process that the rotary peel method uses. Rotary-peeled engineered hardwoods tend to have a plywood appearance in the grain. This style of manufacturing tends to have problems with the wood cupping or curling back to its original shape. The veneer is then pressed flat with high pressure. After preparation, the wood is peeled by a blade starting from the outside of the log and working toward the center, thus creating a wood veneer. This process involves treating the wood by boiling the log in water. Oak herringbone parquet floor with two-strip wenge border Other wood manufacturing styles Rotary-peel Solid wood floors are mostly manufactured 0.75 inches (19 mm) thick with a tongue-and-groove for installation. Many solid woods come with grooves cut into the back of the wood that run the length of each plank, often called 'absorption strips,' that are intended to reduce cupping. The moisture content at time of manufacturing is carefully controlled to ensure the product does not warp during transport and storage.Ī number of proprietary features for solid wood floors are available. The timber is cut to the desired dimensions and either packed unfinished for a site-finished installation or finished at the factory. Depending on the desired look of the floor, the timber can be cut in three ways: flat-sawn, quarter-sawn, and rift-sawn. Solid wood flooring is milled from a single piece of timber that is kiln or air dried before sawing. It is not uncommon for homes in New England, Eastern Canada, USA, and Europe to have the original solid wood floor still in use today. Solid wood floors have a thicker wear surface and can be sanded and finished more times than an engineered wood floor. However, solid wood floors are still common and popular, but are commonly more expensive in the United States and considered higher end. With the increased use of concrete as a subfloor in some parts of the world, engineered wood flooring has gained some popularity. Solid hardwood floors were originally used for structural purposes, being installed perpendicular to the wooden support beams of a building known as joists or bearers. The wood is also known for emitting an earthy, musty odor during planing or machining.Solid hardwood floors are made of planks milled from a single piece of timber. Installation: Zebrawood’s interlocking grain may present some difficulty when sanding, and care must be used to avoid grain tear out. However, woods at the very top of the Janka Hardness Scale could be too difficult to cut for home applications. Woods at the low end of the scale will show more evidence of dings compared to those at the top. That result leads to the wood’s Janka Hardness rating. The test, which uses a 2” x 2” x 6” piece of a wood specimen and a steel ball, determines how many pounds per square inch of force will make the steel ball embed halfway into the wood. The Janka Hardness scale is used to determine a hardwood’s resistance to dents, dings and scratches. Janka Hardness Rating: With a Janka Hardness rating of 1830 out of 4000, Zebrawood is in the high-medium range of hardwoods. Origins: Zebrawood grows in the African nations of Gabon, Cameroon and Congo. Its scientific name is Microberlinia brazzavillensis. Outside of the United States, it’s also called Zingana and Zebrano. Name: Zebrawood’s familiar name comes from its contrasting heartwood and sapwood, which may resemble zebra stripes.
