The Floor Educational Guild Free Technical Bulletin
Knowledge is your power to increase profits
Move Beyond Certification, Become Educated.
In this Issue, important information about engineered wood, we continue to promote our Kiln Drying Class, a short discussion on our promise to always have technical and science classes for you the flooring professional; and once again, we spotlight an important flooring professional.

The Guild provides information that is usually taught or available from other schools.
We are not supported by any organization or company by donations. Our classes are priced to enable everyone to be able to attend, learn, grown in our industry to increase and protect profits.
The information in this email is not "subjective" or false. It is proven science by scientists and engineers.
This is one reason, we try to spotlight experts in flooring recognized by the industry as experts by their knowledge, experience and willingness to share the truth-experiences of their "flooring careers".
Many instructors from other schools and associations have attended our advance classes.
Our wood science classes area taught by wood scientists, with hands-on experience and are instructors for the wood industry.
Someone asked, if Kiln Drying was "subjective". No, it is factual and honest, and our classes are taught without bias.
it is based upon many years of experience, knowledge from that experience doing kiln drying, and the science that is taught to kiln drying operators so they can avoid drying defects.
We don't hide the truth, we embrace it.

Kiln Drying
for
Hardwood Flooring Professionals
In our upcoming class at Virginia Tech, in their laboratory classroom, we will be taught the art, skill and science of drying hardwood lumber that eventually becomes our wood flooring.
As we are studying the science of kiln drying, we will also be using samples and photographs to discuss other issues with wood flooring that are considered grading issues.
Many of these issues you may never see since most are culled by the wood flooring mills but, sometimes, even the best grader may miss one.
This is your opportunity to learn the truth.
Not all photographs are grading or drying defects.

Kiln Drying Class for the Hardwood Flooring Professional
Class Outline by Dr. Brian Bond and letter to you from Dr. Bond
Hardwood Lumber Drying for Wood (flooring) Products
(From Dr. Bond, Virginia Tech University, July 6, 2017)
The operation of a lumber drying facility, especially one drying oak, requires special skills. A significant amount of lumber may be degraded or damaged during drying when proper techniques are not used.
The Flooring Educational Guild has partnered with Dr. Brian Bond to conduct a program is designed for new and beginning dry kiln and pre-dryer operators, flooring inspectors, and commercial wood products manufactures.
The program assumes no experience in lumber drying. Topics will include the basics of lumber drying, air-drying, lumber handling, predryer and kiln operation, schedules, conditioning, and quality control procedures.
The course will include drying a charge or yellow-poplar lumber and touring a commercial drying facility. The program will be held at the Brooks Forest Products Center, Virginia Tech, Blacksburg, VA on August 21-23, 2017.

In our next issue, we will continue with moisture issues and flooring, and how important it is to understand some basic concepts for the climates we work and live.
However, for this issue, we have excerpts from an old but still applicable document from the Forest Products Laboratory about engineered wood.
MANUFACTURE AND GENERAL CHARACTERISTICS OF FLAT PLYWOOD
Products Laboratory, Forest U.S. Department of Agriculture
"Plywood is manufactured by bonding thin sheets of wood (veneers) together with adhesives in such a way that the mechanical and physical properties of the wood are redistributed. This manufacture of plywood requires special equipment, knowledge, and technique. Important steps in the process of making flat plywood are outlined here, as well as information on types and grades and some properties of plywood. The information is based upon observations of factory practice and upon extensive experiments at the Forest Products Laboratory."
Some Properties of Plywood
"The chief advantages of plywood, as compared with solid wood, are its approach to equalization of strength properties along the length and width of the panel, greater resistance to checking and splitting, and less change in dimensions with changes in moisture content. The greater the number of plies for a given thickness, the more nearly equal are the strengthand shrinkage properties along and across the panel and the greater is the resistance to splitting."
"The shrinkage of plywood varies with the species, the ratios of ply thicknesses, the number of plies, and the combination of species. Three-ply panels, with all plies in any one panel of the same thickness and species, were dried from a soaked to an ovendry condition at the Forest Products Laboratory.
Measurements showed about 0.45 percent shrinkage parallel to the face grain and 0.67 percent shrinkage perpendicular to the face grain, with ranges of from 0.2 to 1 percent and 0.3 to 1.2 percent, respectively.
The panels tested ranged in thickness from 1/10 to 1/2 inch. For all practical purposes, shrinkage of plywood in thickness does not differ from that of solid wood."
Plywood shrinks from desorption of moisture and swells with the absorption of moisture.
Why is this important to Flooring Professionals
If it shrinks after it is installed as flooring, we see gaps between the ends of the planks.
If it can shrink, it can swell and when that happens, we see compressed peaked end-joints.
Moisture gain after installation swelling more in the length than the width.
