A big concern when purchasing your
hardwood is, JUST HOW HARD IS IT?
Below you will find a "JANKA HARDNESS CHART"
which was devised to help determine just "HOW
HARD IT IS."
The Janka hardness
test measures the force required to embed a .444-inch
steel ball to half its diameter into the wood. It is one
of the known ways to test the ability and wear of
hardwood flooring. The higher the number, the harder
the species of wood. It has been broken up into three
parts, the middle selection denotes the average species
purchased.

SOLID WOOD
FLOORS
These floors are one piece of
solid wood from top to bottom. They generally are
3/4 thick, however also come in 5/16"
thickness as well 3/8 . The most commonly
recognized width is 2 1/4 strip flooring, but also
comes in sizes from 1 1/2 strips to 7" wide
planks. Lengths will be random from 12"
96 long. Custom Milled solid hardwood flooring can
also be milled to your specifications and usually comes
in long lengths up to 14-16 foot long. Solid
strip or plank floors can only be installed with the Nail
or Staple Down procedure on a wooden sub-floor.
Part of the difference between
3/4" solid wood floors and most engineered wood
floors is how the wood is cut from the tree. As the
picture above (left) shows you the 3/4" solid wood
planks are cut (sliced) lengthwise to the log. While most
engineered type wood flooring (right) is rotary cut using
a razor sharp blade into veneer sheets of up to 1/8
thick that are later glued and pressed to the top of a
plywood type substrate for stability and strength. The
New Satin Finish "Multi-plank" engineered
flooring is sliced like the solid flooring is to give it
the thickest wear surface of all engineered floors.
SOLID HARDWOOD flooring is
also available in either PLAIN SAWN which is most
common and QUARTERSAWN which usually has to be
special ordered.
PLAIN SAWN
- Plain sawn, or Flat sawn, is the standard way
of cutting logs into lumber, or flooring. Plain
sawn can produce wide grain patterns (depending
on the wood species)
QUARTERSAWN
- Quarter sawing, means that the log is cut at
right angles to the growth rings. This flooring
has a very decorative grain patterns and produces
more stability during changes in humidity.
