Face Nailing—Fastening through both the overlapping and the overlapped
panel; the fastener head will be visible.
Fascia—A flat, horizontal band that covers the rafter tails and runs along the
bottom edge of the roof line.
Flashing—A thin, impervious material, usually metal, placed around openings
to prevent water penetration or to direct the flow of water over the cladding.
Frieze—The horizontal trimboard connecting the top of the siding with
the soffit.
Furring/Furring Strip—Long, thin strips of wood or other materials used
to build out the fastening surface of a wall; commonly used to correct
imperfections in wall surfaces, to establish a rainscreen, or to re-establish a
structural fastening surface on the exterior of non-structural products such as
foam insulation.
Gable—The triangle formed on the side or the front of a building by a
sloping roof.
Hot-dip Galvanized—The process of dipping metal into molten zinc to apply
a protective coating that prevents corrosion; hot- dipped galvanized iron and
steel are corrosion resistant.
H-channel Joint—When installing vertical siding or soffit materials, used
to conceal the edges; with lap siding, H-channel or joint covers are used to
cover the butt ends/joints where they come together (mainly for aesthetic
purposes).

joint to help shed water; commonly made of finished metal or #15 felt.

the jambs; also referred to as casing, window, or door surround.
Miter Cut—A beveled cut, usually 45°, made at the end of a piece of molding
or board that is used to form a mitered joint.

the actual coverage of 1,000 sq. ft. for lap siding is 850 sq. ft.
O.C.—On center; a measurement of the distance between the centers of two
repeating members in a structure, usually studs.
