Floors Etc. Glossary of Terms
Definitions
Above Grade
Acclimation
Advanced Generation Nylons / Branded Fibers
These fibers have a specific brand name and are manufactured to a strict set of standards and offer better performance, stain, static, and crush resistance. The fibers have been specially treated with stain and soil resistant resins, applied during the dyeing process. When you purchase a carpet made with any of these fibers, you’ll get a comprehensive warranty from the manufacturer.
Floors Etc. carries the following branded fibers:
- R2X® by Shaw
- Everstrand® by Mohawk
- Smartstrand® by Mohawk

Buckling
Carpet Delamination
condition where the secondary backing of the carpet separates from the primary backing
It can be caused by a variety of issues, including but not limited to:
- a failure of the bonding agent, usually latex, between the primary and secondary backing.
- improper installation
Note: Floors Etc. has never had any reported issues regarding this issue on any carpets we have installed. - water damage – if carpet remains wet for an extended period, it could breakdown or deteriorate the latex glue.
- Carpet loses 85 percent of its structural integrity while wet. Further, microbial growth from water-soaked carpet can actually feed on the latex glue. Carpets at risk are those that:
- have been involved in a flood.
- have been cleaned improperly with too much water
- Carpet loses 85 percent of its structural integrity while wet. Further, microbial growth from water-soaked carpet can actually feed on the latex glue. Carpets at risk are those that:
Cross Joins
Crowning
This is damage due to moisture exposure or imbalance.
Cupping
This is damage caused by excessive moisture which causes wood to expand.
Delamination
damage or defect found on flooring made of composite material like laminate and engineered hardwood
You’ll know delamination when you see it because the flooring top layer begins to separate from the core. The floorboards might bubble or hump in the middle, or the top part might peel back from the edges. (This is not exclusive to flooring as it can be found on any laminate item, like a dresser or cabinet.)
- Moisture damage is the primary culprit.
- The layers that compose engineered wood are typically held together with glue. Intense pressure ensures its longevity and improves its ability to hold its shape, but once water penetrates the layers, the pressure releases and the layers begin to separate.
- The best way to prevent delamination in your floors follow the Maintenance Guidelines provided to you upon installation – among those, be sure to choose your Engineered and Laminate cleaning products carefully
- If the damage has already occurred, try to pinpoint the cause before you have it repaired to ensure you don’t have to deal with a repeat of the issue later.
Density
Dwell Time
Floating
Head Seams
Heartwood
the dead, inner wood, which often comprises the majority of a stem’s cross-section
- Harder than sapwood – generally used for flooring materials
- Natural accents of sapwood can be found in heartwood
- Heartwood can usually be distinguished from sapwood by its darker color.
- HOWEVER:
- Not all heartwood is dark
- Not all dark-colored wood is heartwood
- HOWEVER:
Janka Hardness Scale
determines the hardness of one type of wood over another
Invented in 1906 by Gabriel Janka, an Austrian wood researcher and standardized in 1927 by the American Society for Testing and Materials (ASTM).
Landing
Microlam / LVL
Laminated Veneer Lumber (LVL): an engineered wood product that uses multiple layers of thin wood assembled with adhesives.
Made in a factory under controlled specifications, LVL offers several advantages over typical milled lumber. It is stronger, straighter, and more uniform. It is also much less likely to warp, twist, bow, or shrink. It is typically used for beams, headers, rimboard, and edge-forming material.

On Grade
Old-Growth
the approximate age at which old-growth features begin to appear is about half the maximum age of the predominant tree species (USDA Forest Service)
- Old-growth forests are at least 200 years old
- 8 to 9 million acres of old-growth forests remain – mostly on federally protected land.
- Today most reclaimed wood originates from old-growth timber because most of the structures being deconstructed are more than 100 years old.
OSB – Oriented Strand Board
has the appearance of giant cornflakes pressed together to form structural panels in sizes similar to plywood, such as 4′ x 8′ x 5/8″
Floors Etc. believes plywood is better suited for flooring projects and opts not to use OSB in our flooring projects (exclusively using plywood where OSB might otherwise be substituted).
Pile Height
Quarter Round
Reclaimed Hardwood
Reducer
Risers
Sapwood
the living, outermost portion of a woody stem or branch
- All wood starts as sapwood
- Typically not used as primary source for flooring
Seams
Screeding
the act of applying a well-blended mixture of ordinary cement with graded aggregates and water to a floor base, in order to form a sturdy sub-floor that is capable of taking on the Finish Floor
It is one of the most vital steps in flooring that plays a major role in ensuring the quality, finish and durability of the entire flooring
Shoe Molding
Unlike quarter round molding, the curve of shoe molding is less pronounced (usually ½” wide)
Soiling
the result of a residue or oily substance on the flooring, which then attracts dirt particles
This has the appearance of a stain but is not necessarily the result of a spill (e.g.: residues from a spot treatment product; cooking oil mist residue; even residue from walking on floors in bare feet).
Staining
Certain materials are more prone to staining than others.
Stair Nose; AKA: Nosing; AKA: Bullnose
Substrate
General Definition: any surface below another surface
T-Molding
Threshold - AKA: Saddle
They can be flush (level with the floors) or raised. They can also be used as wide reducers.
Treads
full plank of wood with a rounded edge on the front (laid horizontally as a step or stair)
- Tread With Return – stair tread with rounded edges on the side as well as the front
- Pencil Round Nosing – resembles a pencil that has been laid sideways across the tread
- Square Nosing – more contemporary option that protrudes slightly over the edge of the tread
- No Overhang Nosing – contemporary option that sits flush with the treads
Warping
floor damage that is similar to cupping but is much more severe, which usually involves the floor buckling or even popping off the subfloor
