A
Abrasion: The degree to which a floor tile's surface will withstand foot traffic. There are specific tests determined by ISO to decide which standard or classification a floor tile will receive.
Adhesive: Used for bonding tile to a surface. Rubber solvents: an rubber and resin-based emulsions can be used as adhesives.
Angolo: A decorative corner piece used in floor installations. Often used in conjunction with an fascia to create a "rug" border effect. Some angolos may be used together to create a small rosone.

Embossed:
A decoration in relief or excised on the wear surface.
Epoxy Adhesive: A two part adhesive system employing epoxy resin and epoxy hardener used for bonding ceramic tile to back-up material.
Epoxy Grout:
A two part grout system consisting of epoxy resin and epoxy hardener. Formulated to have impervious qualities, stain and chemical resistance, used to fill joints between tiles.
Exterior tiles: Tiles suitable for outdoor applications because of their frost resistance.
F
Fascia: A decorative piece used in floor installtions. Often used in conjunction with an angolo to create a "rug" border effect.
Field Tile:The main tile in a tile design.
Floor Tile: Any type of tile designated for use on floors. It can generally be used for walls or countertops also.
Formella: Square tile of classic style with antique glazed or bas-relief decoration.
Frost proof:
Product manufactured for use where freezing and thawing conditions occur.
Frost resistance: Ability of certain
ceramic tiles to withstand freeze/thaw
conditions with minimal effect. Frost resistance
of ceramic tile is dependent on the tile’s porosity and water absorption levels. Frost resistance does not guarantee 'frost proof.'
I
Insert or Inserto: A decorative tile that coordinates with a field tile and is the same size. For example, if a field tile is 4" x 4", an insert that coordinates is also 4" x 4", but is decorative.
Impervious tiles: Dust-pressed ceramic tiles with water absorption levels ,0.5% and high mechanical and chemical characteristics. The surface of these tiles may be glazed or unglazed. Also known as vitrified or porcelain tile.
J
Jolly: Trim tiles mitered along one or two edges, used in corner and countertop installations. Also called angled tiles.
L
Lippage: In finished installation, the condition where one edge of a tile is higher than an adjacent tile. May be unavoidable even for tiles that are within the tolerances of dimensional standards, seen especially in very large format tiles.
Listello (or Listel): Italian word for a border tile used to add interest.
Lugged Tile: Tile produced with tabs on the edges for maintaining even spacing. These are usually wall tiles.
M
Majolica: Tiles composed of raw materials that produce a yellow-pink body of relatively high water absorption level.
Mitered:To cut on an angle to meet on an edge or corner (similar to picture frame moldings or celing cove molding).
Moh's scale: Scale used to express the measure of a materials hardness. Talc's rating on Moh's is a 1 where a diamond is 10.
Monocottura: Tiles produced with only
one high temperature firing, generally with
harder glaze and denser body than wall tiles
with moisture absorption below 3 percent.
Mortar: The setting material used to bond tiles to a given surface. Different types of mortar are suitable for different backing and conditions.
Mosaic: Small tiles used to make patterns or pictures on walls or floors. Mosaic tile can be made from ceramic, porcelain, marble, slate, glass or metal.
Mounted tiles: tiles assembled into units or sheets by the manufacturer for easier installation. Back and edge mounted tiles are bonded to material (mesh, paper, resin or other) that becomes part of the installation. Face mounted tiles are bonded to a material that is removed prior to grouting.
O
Out Corner: A trim piece with two connecting edges bullnosed.
P
P.E.I.: Porcelain Enamel Institute, responsible for research, testing and analysis of ceramic materials in the United States.
Pencil: Thin tile of any length usually between 1/2" and 2" in width.
Porcelain tile: An extremely durable tile that is often used commercially. Porcelain tiles can be glazed or unglazed due to their low porosity.
Portland cement: Type of hydraulic cement often used in tile installation.
Q
Quarter Round or Bead: A narrow, convexly curved piece designed to create continuity where 90 degree angles occur.
Quarry tile: Traditional term for single-extruded, natural clay tiles with a water absorption level not exceeding 6%.
R
Rectified Tile: Rectified tile is first baked in sheets, then cut to size AFTER coming out of the kiln. This is why it can be calibrated to exact specifications. Rectified tile can be installed with “credit card” joints as small as 1/16”. Most other tile is first shaped and then baked afterwards in a kiln, so it often has as much as a 1/16" or more difference in size between tiles in the same box.
Rosone: A square or circle design used as a decorative piece in a floor installation. Rosones are often made of mosaics of stone or glass, sometimes in intricate water-jet patterns.
Running Bond : Tile is set in a staggered pattern similar to a brick wall. Also know as a brick pattern.
S
Screeding: Leveling the mortar bed by dragging a screed across it.
Sealers: Clear coating sometimes applied to unglazed tile floor to protect the surface from grease spills or to add luster.
Single-fired tiles: Glazed tiles produced by the single-firing method in which the raw tile body and glaze undergo a single pass through the kiln at high temperature. Also known as monocottura.
Stacked set: Setting a tile in a stacked set just means to center adjacent tiles next to each other without any stagger. Any shape tile that is square or rectangular may be set with a stacked pattern.
Straight Set: Tile set square to the wall.
Subway tile: The shape of a subway tile is rectangular and very flat, set with a tight grout joint, and often comes in sizes such as 3"x6", 4"x8", etc. Modern subway tiles tend to be beveled on the edge, allowing for a deeper grout joint. Subway tiles can be set in a brick pattern or stacked verticially or horizontally.
T
Terra Cotta: Tiles produced with only
one high temperature firing, generally with
harder glaze and denser body than wall tiles
with moisture absorption below 3 percent.
Trim: Finishing pieces used to cover exposed tile bisque (i.e. bullnose, out corners, step nosing).
W
Wainscote: The area of a tiled wall that is installed from the floor to the chair rail height, or slightly higher, with a border or cap finishing the installation.
Wall Tile: Tile intended for use on walls. Generally thinner than floor tile. While it can sometimes be used on residential floors and countertops, it is best to consult manufacturer recommendations before installation. |
