Felt – Fibrous material saturated with asphalt and used as an underlayment or sheathing paper.
Fiber glass mat – An asphalt roofing base material manufactured from glass fibers.
Flashing – Pieces of metal or roll roofing used to prevent seepage of water into a building around any intersection or projection in a roof such as vent pipes, chimneys, adjoining walls, dormers and valleys. Galvanized metal flashing should be minimum 26-gauge.
Flashing Cement – See asphalt plastic roofing cement.
Free-tab shingles – Shingles that do not contain factory-applied strips or spots of self-sealing adhesive.
FAÇADE - The front of a building. Frequently, in architectural terms an artificial or decorative effort.
FACE BRICK- Brick made especially for exterior use with special consideration of color, texture and size, and used as a facing on a building.
FACE GLAZING – A system having a triangular bead of compound applied with a putty knife, after bedding, setting, and clipping the glazing infill in place on a rabetted sash.
FACTORY MUTUAL FM - A major insurance agency who has established stringent guidelines for maximum construction integrity as it relates to fire and environmental hazards. Their specifications have become industry standards.
FASCIA - Any cover board or framed metal assembly at the edge or eaves of a flat, sloping, or overhanging roof which is placed in a vertical position to protect the edge of the roof assembly.
FASTENERS - A general term covering a wide variety of screws and nails which may be used for mechanically securing various components of a building.
FELT - A very general term used to describe composition of roofing ply sheets, consisting of a mat of organic or inorganic fibers unsaturated, impregnated with asphalt or coal tar pitch, or impregnated and coated with asphalt.

FERROUS – Refers to objects made of or partially made of iron, such as ferrous pipe.
FILLET BEAD – Caulking or sealant placed in such a manner that it forms an angle between the materials being caulked.
FINISH – In hardware, metal fastenings on cabinets which are usually exposed such as hinges and locks.
FINISH CARPENTRY - The hanging of all interior doors, installation of door molding, base molding, chair rail, built in shelves, etc.
FINISH COAT – The last coat applied in plastering intended as a base for further decorating or as a final decorative surface. Finish coat usually consists of calcified gypsum, lime and sometimes an aggregate. Some may require the addition of lime or sand on the job. The three basic methods of applying it are (1) trowel (2) flat and (3) spray.
FINISH GRADE – Any surface which has been cut to or built to the elevation indicated for that point. Surface elevation of lawn, driveway or other improved surfaces after completion of grading operations.
FIRE-RATED – Descriptive of materials that has been tested for use in fire walls.
FIRE WALL – Any wall built for the purpose of restricting or preventing the spread of fire in a building. Such walls of solid masonry or concrete generally sub-divide a building from the foundations to two or more feet above the plane of the roof.
FISH TAPE (Fish Wire) – Material used to advance wire through a conduit.
FLAKE – A scale-like particle. To lose bond from a surface in small thin pieces. Sometimes a paint film "flakes".
FLASHING – Weatherproof material installed between roof sheathing (or wall sheathing) and the finish materials to help keep moisture away from the sheathing.
FLASHING BASE – The upturned edge of the watertight membrane formed at a roof termination point by the extension of the felts vertically over the cant strip and up the wall for a varying distance where they are secured with mechanical fasteners.
FLASHING, COUNTER – The formed metal secured to a wall, curb, or roof top unit to cover and protect the upper edge of a base flashing and its associated fasteners.
FLASHING, STEP – Individual small pieces of metal flashing material used to flash around chimneys, dormers, and such projections along the slope of a roof. The individual pieces are overlapped and stepped up the vertical surface.
FLASH POINT - The critical temperature at which a material will ignite.
FLASHING, THRU-WALL – Flashing extended completely through a masonry wall. Designed and applied in combination with counter-flashings, to prevent water which may enter the wall above from proceeding downward in the wall or into the roof deck or roofing system.
FLAT GLASS – A general term that describes float glass, sheet, glass, plate glass, and rolled glass.
FLAT SEAM - A seam at the junction of sheet metal roof components that has been bent at the plane of the roof.
FLEET AVERAGING – By using a point system, builders can show compliance with energy building requirements by using average figures for all air conditioning units in the same sub division.
FLEXIBLE METAL CONDUIT – Conduit similar to armored cable in appearance but does not have the pre-inserted conductors.
FLOAT GLASS – Glass formed on a bath of molten tin. The surface in contact with the tin is known as the tin surface or tin side. The top surface is known as the atmosphere surface or air side.
FLOOR PLAN – The basic layout of building or addition, which includes placement of walls, windows and doors as well as dimensions.
FLOOR PLATE – See Floor Plan.
FLUSH GLAZING (Pocket Glazing) – The setting of a lite of glass or panel into a four-sided sash or frame opening containing a recessed "U" shaped channel without removable stops on three sides of the sash or frame and one channel with a removable stop along the fourth side.
FOLDED SEAM – In sheet metal work, a joint between sheets of metal wherein the edges of the sheets are crimped together and folded flat.
FOOTINGS – Wide pours of cement reinforced with re-bar (reinforcing bar) that support foundation walls, pillars, or posts. Footings are part of the foundation and are often poured before the foundation walls.
FOOT PRINT – See Floor Plan.
FULLY ADHERED – A completely attached (adhered) roof membrane.
FULLY TEMPERED GLASS – Flat or bent glass that has been heat-treated to a high surface and/or edge compression to meet the requirements of ASTM C 1048, kind FT. Fully tempered glass, if broken, will fracture into many small pieces (dice) which are more or less cubical. Fully tempered glass is approximately four times stronger than annealed glass of the same thickness when exposed to uniform static pressure loads.
FURNACE – A heating system that uses the principle of thermal convection. When air is heated, it rises and as the air cools it settles. Ducts are installed to carry the hot air from the top of the furnace to the rooms. Other ducts, called cold air returns, return the cooler air back to the furnace.
FACADE – The front of a building. Frequently, in architectural terms an artificial or decorative effort.
FACTORY MUTUAL FM – A major insurance agency who has established stringent guidelines for maximum construction integrity as it relates to fire and environmental hazards.Their specifications have become industry standards.
