Results

ease: To slightly soften the sharp edge on a piece of wood by slightly rounding are applying a slight bevel.

eased edge: The chamfered or beveled edge of strip flooring, plank, block and parquet at approximately a 45 degree angle.

edge banding: Thin solid wood or veneer strips used to cover the exposed edges of panel products such as plywood. Generally applied oversized and flush trimmed.

edge joining: Squaring the edges of two boards and gluing them together in an edge joint.

edge joint: A joint made by bonding two pieces of wood together edge to edge usually by gluing. A plain edge joint is also called a butt joint.

edge miter joint: A joint where the edge of one plank meets the edge of another plank at 90 degrees and each edge is cut on a 45 degree angle.

edge profiles: A machined shape on the outside edge of a cabinet door or drawer.

effervescence: An effect that can happen in a finishing agent if there is rapid release of volatile gasses. This causes pinhole or cratered appearance reducing gloss.

elastic limit: The extent of deformation beyond which a material will not return to its original shape.

elasticity: That property of a substance which allows it to stretch or to change size or shape and to return to its original condition without breaking or rupturing.

embossing: Refers to the surface treatment in which heat and pressure against a master pattern wheel impresses a variety of textured effects into the wood surface, which still remains smooth and paintable. Example: crown moulding embossed with egg and dart profiles

EMC - Equilibrium Moisture Content: The moisture content at which wood neither gains nor loses moisture when surrounded by air of a given relative humidity and temperature.

enamel: A colored varnish or high gloss paint for interior use that has a sheen level from satin to glossy.

encased knot: A loose knot in which the annual rings are not inter-grown with the surrounding wood, and there may be pitch pockets and areas of bark between the knot and the surrounding wood. Formed when a branch dies, leaving a cylinder of dead wood inside the growing

end check: A through check at the end of a board; a split in the end of the board that occurs as a drying defect.

end grain: The wood grain as seen looking at the end of a plank as opposed to the edge or face.

end joint: The place where two pieces of flooring are joined together end to end.

end matched: The ends of individual planks have a tongue milled on one end and a groove milled on the opposite end, so that when the planks are butted together, the tongue of one piece engages the groove of the next piece.

engineered: An assembly made by bonding layers of veneer or lumber with an adhesive so that most adjacent layers have their grains going in perpendicular directions to increase dimensional stability.

engineered wood flooring: A wood flooring product manufactured by gluing thick hardwood veneer onto a plywood base and with T & G on the edges.

epicormic branch: A branch growing out of the main stem of a tree from buds produced abnormally- increases knottiness and reduces lumber quality. – usually brought on or aggravated by fire or damage to the tree.

epoxy: A two part resin plus hardener glue that is very strong, low shrinking during drying and will bond most materials. Also a finishing agent that is highly resistant to mechanical wear and to water and chemical stains. comes in a two part system and produces

equal linear pattern: Also commonly referred to as a repeating pattern. For installation purposes where more than one width of flooring is used, a specific pattern is created by alternating widths in a consistent sequence so as to use equal lineal footages of each width.

evaporation: The process by which a liquid turns to a gas- a process by which volatile organic compounds (VOC’s) are eliminated from finishing agents.

evergreen: A tree that does not drop its leaves in the fall. Conifers are evergreen. Tend to be softwoods, but some hardwoods in tropical and temperate climates are evergreen.

exotic wood: Generally refers to imported or tropical species, but may contain indigenous species with exceptional figure or grain.

expansion space: The necessary gap that separates hardwood floor from any fixed objects like walls, door jambs, kitchen islands, and exposed pipes. Expansion space recommended to be at least ¼” in normal sized rooms.

exterior glue: Adhesive used for outdoor applications. May be waterproof or water resistant.

extractives: Chemicals created in wood as the sapwood dies and becomes heartwood- the cause of the difference between heartwood and sapwood- also gives heartwood the resistance to decay and insect attack.

exudates: Secretions such as resin, gum, oil or latex over the surface of lumber, created by kiln drying at high temperatures. May adversely affect machining, gluing and finishing.

eye: A localized distortion of wood fiber, roughly circular in shape- such as bird’s eye figure an some burls.
