GLOSSARY

Here is a list of commonly used words in the cabinet and granite industry

  1. Base Cabinet - A cabinet that sits on the floor.
  2. Bead Board - Wood paneling that contains vertical parallel grooves to give the cabinet added style and texture.
  3. Beaded Door - The bead styling usually found on a recessed panel door.
  4. Carcass - Term used for the box of the cabinet.
  5. Concealed Hinge - A hinge that is attached to the back of the door so it cannot be seen when the door is shut.
  6. Dado - A groove cut into the wood to allow for another piece to fit in.
  7. Dove Tail - A common joint technique used in woodworking. A series of male pins are cut from one end of the board to the other designed to interlock with a series of female tails. A dovetail joint does not require any additional fasteners once it has been glued and locked together. This kind of joint system is noted for its strong structure.
  8. Drawer Face - The front panel of the drawer. Sometimes matches the door profile or comes in a slab look.
  9. Engineered Wood - This is not natural wood. It is enhanced for improved structural purposes. Because engineered wood is oftentimes created from leftovers of other types wood, it is considered an environmentally friendly product. MDF is an example of engineered wood.
  10. Face Frame - The outer frame that attached to the side and bottom panels. This is for a framed cabinet only.
  11. Finish - The finish is the final layer applied to the cabinet. It locks in the color as well as provides protection to the surface.
  12. Flat Panel - This style of cabinet has an “indented” or “recessed” center panel. There are a large variety of flat panel cabinets.
  13. Framed Cabinets - This is the sturdiest and most common cabinet design. It includes a frame around the front side of the cabinet box
  14. Frameless Cabinets - Known as a popular European style cabinet. The front side of the cabinet box does not have a frame around it.
  15. Full Inset - Doors and drawers that fit inside the face frame opening. Doors and drawers will sit flush with the front edge of the face frame.
  16. Full Overlay - Type of door that covers most of the face frame. Typically found in the frameless cabinet style, but can be used on framed cabinets as well.
  17. Glaze - Comes in a variety of colors and types. Glazes are designed to enhance the wood’s natural beauty. It is a detailed coat that provides another unique appearance
  18. MDF (Medium Density Fiberboard) - Also known as Medium Density Fiberboard, an engineered wood product construction from bonding agents and small wood particles. MDF is commonly used as the core of a cabinet door then covered with melamine, laminate or thermofoil. This MDF core provides the cabinet with more structural integrity by reducing the occurrences of shrinkage and expansion of the center panel. Compared to particle board, MDF is better and easier to work with because of the use of the small wood particles. Particle board uses larger pieces.
  19. Melamine - Used to cover door and drawer surfaces, melamine is a popular plastic material that is known for its ease to clean.
  20. Mullion Doors - Cabinet doors with a grid like pattern with a glass center panel. Please note glass may not be included. Please check with sales rep.
  21. Overlay - This term is used to describe the amount the face frame is covered by the front of the door or drawer.
  22. Regular Overlay - Doors and drawers cover only a portion of the overall frame
  23. Rail - Horizontal pieces of the face frame
  24. Recessed Door - The center panel of a cabinet door that is indented or recessed to offer a unique style and design
  25. Reveal - The exposed portion of the face frame when the cabinet doors and drawers are shut.
  26. Semi-Custom Cabinets - This is a factory made product. In terms of price and variety, semi-custom cabinets are only one step below custom cabinets. They are a very affordable option and still have the ability to make your dream kitchen come to life.
  27. Soffit - An area above the top of the cabinets that generally sticks out over the cabinets. Many times this is converted into a shelf for added storage and needs to be worked around when designing your kitchen.
  28. Solid Wood - Ordinary lumber milled and sanded to provide the best quality material used for cabinets. Provides the most structurally sound cabinet.
  29. Species of Wood - Refers to the many types of wood options you have. Species are differentiated by wood grain, density, color and more.
  30. Stile - Vertical pieces of the face frame
  31. Substrate - Refers to the material that a veneer is applied to.
  32. Thermofoil - This is another cabinet material made from heat fusing thin layers of PVC to a substrate. Thermofoil is easy to clean, durable and smoother than paint.
  33. Toe Kick - The bottom piece of the base cabinet that is notched back to allow for foot room under the cabinet.
  34. Veneer - Veneer consists of thin wood strips that are adhered to a core panel such as particle board or MDF. Since the wood’s main purpose in a veneer is not to provide the overall support of the cabinet but rather gives us an opportunity to choose from the highest quality cuts of wood to provide a aesthetics pleasing look.
  35. Wall Cabinets - Cabinets that are mounted to the wall.
  36. Wood Grain - The pattern in the wood. This will differ depending on the wood species.

crystalline limestone
a limestone, either calcitic or dolomitic, composed of interlocking crystalline grains of the constituent minerals and of phaneritic texture; commonly used synonymously with marble and thus representing a recrystallized limestone; improperly applied to limestones that display some obviously crystalline grains in a fine-grained mass but which are not of interlocking texture and do not compose the entire mass. (NOTE: All limestones are microscopically, or in part megascopically, crystalline, ; the term is thus confusing but should be restricted to stones that are completely crystalline and of megascopic and interlocking texture and that may be classed as marbles).

According to their mineralogic compositions, gneisses may correspond to other rocks of crystalline, visibly granular, interlocking texture, such as those included under the definition of commercial granite, and may then be known as granite gneiss if strongly foliated, or gneissic granite if weakly foliated.

black granite
rock species known to petrologists as diabase, diorite, gabbro, and intermediate varieties are sometimes quarried as building stone, chiefly for ornamental use, and sold as "black granite". As dimension blocks or slabs, they are valued specifically for their dark grey to black color when polished. Scientifically, they are far removed in composition from true granites though they may be satisfactory used for some of the purposes to which commercial granites, are adapted. They possess an interlocking crystalline texture, but unlike granites, they contain little or no quartz or alkalic feldspar, and are characterized by an abundance of one or more of the common black rock-forming minerals (chiefly pyroxenes, hornblende, and biotite).

rustication
chamfers or square sinkings around the face edges of individual stones to create shadows and to give an appearance of greater weight to the lower part of a building. When only the horizontal joints are sunk, the device is known as banded rustication.

rustification
recessing the margin of cut stone so that when placed together a channel is formed at each joint.
tablet
a small, flat slab or surface of stone, especially one bearing or intended to bear an inscription, carving or the like.

template

terrazzo
a type of concrete in which chips or pieces of stone, usually marble, are mixed with cement and are ground to a flat surface, exposing the chips, which take a high polish.

texture
three dimensional surface enrichment independent of color.

thin stone
stone slabs generally of two inches or less in thickness.

thin marble
a fabricated marble unit of 2 inches (50 mm) thick.

tile
a thin modular stone unit.

tolerance
dimensional allowance made for the inability of men and machines to fabricate a product of exact dimensions.

throat
the name sometimes given to the small groove under the windowsill or dripstone, intended of deflect rain water from the wall face.

tooled finished
customarily are four, six or eight parallel, concave grooves to the inch.

tracery
ornamentation of panels, circular windows, window heads, etc.

translucence
permitting light to pass through with little diffusing. Certain marble varieties are translucent.

travertine
a form of limestone precipitated from ground waters, as in caves or in orifices of springs (see limestone group).

travertine limestone
a variety of limestone that has a partly crystalline or microcrystalline texture and porous or cellular layered structure, the cells being usually concentrated along certain layers and commonly displaying small stalactic forms.

travertine marble
a variety of limestone regarded as a product of chemical precipitation from hot springs. Travertine is cellular with the cells usually concentrated in thin layers that display a stalactic structure. Some that take a polish are sold as marble and may be classified as travertine marble under the class of "Commercial Marble."

tread
a flat stone used as the top walking surface on steps.

trim
stone used as decorative items only, such as sills, coping, enframements, etc., with the facing of another material.

trimmer arch
a stone arch, usually a low-rise arch, used for supporting a fireplace hearth.

tuff
cemented volcanic ash, many varieties included.
undercut
cut so as to present and overhanging part.
vein cut
cutting quarried marble or stone perpendicular to the natural bedding plane.

veinings
colored markings in limestone, marble, alabaster, etc.

veneer stone
any stone used as a decorative facing material which is not meant to be load-bearing.

venting
creating an outlet in a wall for air and moisture to pass through. (see cavity vent.)

verd (or verde) antique
a marble composed chiefly of massive serpentine and capable of being polished. It is commonly crossed by veinlets of other minerals, chiefly carbonates of calcium and magnesium.

vug
a cavity in rock, sometimes lined or filled with either amorphous or crystalline material, common in calcereous rocks such as marble or limestone.
wall plate
a horizontal member anchored to a masonry wall to which other structural elements may be attached. Also called "head plate."

walls
one of the sides of a room or building connection floor and ceiling or foundation and roof:

wall, bearing
a wall supporting a vertical load in addition to it own weight.

wall, cavity
a wall in which the inner and outer wythes are separated by an air space but tied together with metal ties.

wall, composite
a wall in which the facing and backing are of different materials and bonded together with bond stones to exert a common reaction under load.

wall, veneer, or faced
a wall in which a thin facing and the backing are of different materials but not so bonded as to exert a common reaction under load.

wall, wind (wined)
a twisting warp from cutting slabs in the gang saws.

wall, wythe
the inner or outer part of a cavity wall.

wall tie
a bonder or metal piece which connects wythes of masonry to each other or to other materials.

wall tie cavity
a rigid, corrosion-resistant metal tie which bonds two wythes of a cavity wall. It is usually steel, 3/16" in diameter and formed in a "Z" shape or a rectangle.

warped walls
generally a condition experienced only in flagging or flagstone materials; very common with flagstone materials that are taken from the ground and used in their natural state. To eliminate warping in stones it would be necessary to further finish the material, by methods such as machining, sand rubbing, honing or polishing.

wash
a sloped area, or the area water will run over.

water bar
typically a strip in a reglet in window sill and stone below to prevent water passage.

water table
a projection of lower masonry on the outside of the wall, slightly above the ground. Often a damp course is placed at the level of the water table to prevent upward penetration of ground water.

waxing
an expression used in the marble finishing trade to indicate the filling of natural voids with color blended materials.

wear
the removal of material or impairment of surface finishing through friction or impact use.

weathering
natural alteration by either chemical or mechanical processes due to the action of constituents of the atmosphere, surface waters, soil and other ground waters, or to temperature changes; the inclined top surface of a stone such as a coping, cornice, or window sill.

splitting of stone by driving wedges into planes of weakness.

weep holes
openings placed in mortar joints of facing material at the level of flashing to permit the escape of moisture.

wind
wined) - a twisting warp from cutting slabs in the gang saws.

wire saw
method of cutting stone by passing a twisted, multistrand wire over the stone and immersing the wire in a slurry of abrasive material.

wythe
the inner or outer part of a cavity wall.
