A sloping end cut on a wood beam or joist where it enters a masonry wall.The purpose of a firecut is to allow the wood member to rotate out of the wall without prying the wall apart, if the floor or roof structure should burn through in a fire.

Fireproofing:
Material used around a steel structural element to insulate it against excessive temperatures in case of a fire.

Fire Seperation Wall:
A wall required under a building code to divide two parts of a building from one another as a deterrent to spread of fire.

Firestop:
A wood or masonry baffle usd to close an opening between studs or joints in a balloon or platform frame in order to retard the spread of fire through the opening.

Firestopping:
A component or mastic installed in an opening through a floor or around the edge of a floor retard the passage of fire.

Fire Wall:
A wall extending from foundation to roof, required under a building code to seperate two parts of a building from one another as deterrent to the spread of fire.

Fire Zone:
A legally designated area of a city in which construction must meet established standards of fire resistance and/or combustibility.

The process of converting dry clay or shale into a ceramic material through the application of intense heat.

First Cost:
The ost of construction.

Glass that is immovably mounted in a wall.

Flagstone:
Flat stones used for paving or flooring.

Flame Spread Rating:
A measure of the rapidity with which fire will spread across the surface of a material as determined by ASTM E84.

Flange:
A projecting crosspiece of a wide-flange or channel profile;a projecting fin.

Flash Cove:
A detail in which a sheet of resilient flooring is turned up at he edge and finished against the wall to create an integral baseboard.

Flashing:
A thin, continuous sheet of metal,plastic,rubber or waterproof paper used to prevent the passage of water through a joint in a wall, roof or chimney.

Flat Seam:
A sheet metal roofing seam that is formed flat against the surface of the roof.

Flemish Bond:
Brickwork laid with each course consisting of alternating headers and stretchers.

Flitch-liced Veneer:
A thin sheet of wood cut by passing a block of wood vertically against a long,sharp knife.

Float:
A small platform suspended on ropes from a steel building frame to permit ironworkers to work on a connection; a trowel with a slightly rough surface used in a intermediate stage of finishing a concrete slab as a verb, to use float for finishing concrete.

Float Glass:
Glass sheet manufactured by cooling a layer of liquid glass on a bath of molten tin.

Flocculated:
A "fluffy" microstructure of clay particles in which the platelets are randomly oriented.

Flue:

Flouropolymer:
A highly stable organic compound used as a finish coating for building cladding.

Flush:
Smooth,lying in a single plane.

Flush Door:
A door with smooth,planar faces.

Flux:
A material added to react chemically with impurities and remove them from molten metal.Fluxes are used both in steel making and in welding. Welding fluxes serve the additional purpose of shielding the molten weld metal from the air to reduce oxidation and other undesirable effects.

Folded Plate:
A roof structure whose strength and stiffness derive from a pleated or folded geometry.

Footing:
The widened part of a foundation that spreads a load from the building across a broader area of soil.

Form Deck:
Thin, corrugated steel sheets that serve as permanent formwork for a reinforced concrete deck.

Form-release Compound:

Friction Connection:
Two or more strutural steel members clamped together by high-strength bolts with sufficient force that the loads on the members are transmitted between them by friction along their mating surfaces.
