A  

Above Grade
See Suspended Substrate.

Acrylic Impregnation
The generic name for wood-plastic composites using wood impregnated with acrylic monomers and polymerized within the wood cells by heat, pressure or radiation.

Adhesive

Armafelt
A felt compostion backing that allows installation of vinyl sheet flooring of all grade levels. The floor is bonded to the subfloor either by spreading adhesive under the entire floor, or by using adhesive only around the perimeter and at the seams (Armafelt Options).

Armafelt Options
An Armstrong installation system for residential vinyl flooring with the Armafelt backing. Armafelt Options provides the option of installing some residential Armafelt backed floors with adhesive under the entire area of the floor (full spread) or just around the perimeter (perimeter bond). Due to the floors' accommodating properties which allow for installation over wood, concrete and existing resilient substrates, less adhesive is needed for the installation of some Armafelt backed floors and therefore installers save time on installation.

B

Base-Shoe Combo

Below Grade
Below ground level; partially or completely below the surrounding ground level and in direct contact with the ground or with fill which is in direct contact with the ground.

Beveled Edge
An angular edge and/or end treatment used on flooring.

Blooming
Also referred to as “drying room yellowing," "drying room film" or "stove yellowing," this is a natural phenomenon that occurs during the manufacturing process of all linoleum. As linoleum cures in the drying room, a yellowish cast may develop on the surface due to the oxidation of the linseed oil. This is not a product defect. Any change in the product's appearance because of this yellow cast is temporary and disappears after exposure to either natural or artificial light. The time required for the yellow cast to disappear ranges from a few hours to several weeks depending on the type and intensity of the light source. Typically, the yellow cast disappears more quickly with exposure to natural light. The application of floor finishes will not interfere with the dissipation of the yellow cast. On areas of linoleum not exposed to light, elimination of the yellow cast will not occur.

Board Width
The width of the individual wood boards that make up the floor. “Strips” are narrow boards measuring less than 3 inches wide. “Planks” are wider boards measuring more than 3 inches wide. "Wide plank flooring” refers to wood boards that are more than 5 inches wide.
