Algae discoloration – A type of roof discoloration caused by algae.Commonly called fungus growth.
American method – Application of giant individual shingles with the long dimension parallel to the rake. Shingles are applied with a 3/4-inch space between adjacent shingles in a course.
ASTM – American Society for Testing and Materials. A voluntary organization concerned with development of consensus standards, testing procedures and specifications.
Asphalt – A bituminous waterproofing agent applied to roofing materials during manufacturing. Asphalt plastic roofing cement: An asphalt-based cement used to bond roofing materials. Also known as flashing cement or mastic; should conform to ASTM D-4586.
AAMA – Architechtural Aluminum Manufacturer’s Association.
ABOVE-GRADE – The portion of a building that is above ground level.
ACRE – 43,500 square feet.
A/C CIRCUIT - (Alternating Current) The flow of current through a conductor first in one direction then in reverse. It is used exclusively in residential and commercial wiring because it provides greater flexibility in voltage selection and simplicity of equipment design.
ACCELERATOR – Any material added to stucco, plaster or mortar which speeds up the natural set.
ADHESION – The property of a coating or sealant to bond to the surface to which it is applied.
ADHESIVE FAILURE – Loss of bond of a coating or sealant from the surface to which it is applied.
AGGREGATE – Crushed stone, slag or water-worn gravel that comes in a wide range of sizes that is used to surface built-up roofs.
AIR DUCT – Ducts, usually made of sheet metal, that carry cooled air to all rooms.
AIR INFILTRATION – The amount of air leaking in and out of a building through cracks in walls, windows and doors.
AIR FILTERS – Adhesive filters made of metal or various fibers that are coated with adhesive liquid to which the particles of lint and dust adhere. These filters will remove as much as 90% of the dirt if they do not become clogged. The more common filters are of the throwaway or disposable type.
ALLIGATORING – A condition of paint or aged asphalt brought about by the loss of volatile oils and the oxidation caused by solar radiation. "Alligatoring" produces a pattern of cracks resembling an alligator hide and is ultimately the result of the limited tolerance of paint or asphalt to thermal expansion or contraction.
ALUMINUM WIRE – Conductors made of aluminum for carrying electricity. Aluminum generally is limited to the larger wire sizes. Due to its lower conductivity, aluminum wire smaller than No. 12 is not made. Aluminum is lighter and less expensive than copper but not as good a conductor. It also breaks easily.
AMPS (AMPERES) – The rate at which electricity flows through a conductor.
AMMETER – Device to measure the current flowing in a circuit
ANCHOR BOLTS – Bolts which fasten columns, girders or other members to concrete or masonry such as bolts used to anchor sills to masonry foundation. Foundation plates or sills shall be bolted to the foundation with not less than 1/2" diameter steel bolts embedded at least 7" into the concrete or reinforced masonry or 15" into unreinforced grouted masonry & spaced not more than & apart.
ANGLE IRON – A piece of iron that forms a right angle and is used to span openings and support masonry at the openings. In brick veneer, they are used to secure the veneer to the foundation. Also known as shelf angle.
ANNEALING – In the manufacturing of float glass, it is the process of controlled cooling done in a lehr to prevent residual stresses in the glass. Re-annealing is the process of removing objectionable stresses in glass by re-heating to a suitable temperature followed by controlled cooling.
ANTI-WALK BLOCKS – Elastomeric blocks that limit lateral glass movement in the glazing channel which may result from thermal, seismic, wind load effects, building movement, and other forces that may apply.
APRROACH – The area between the sidewalk and the street that leads to a driveway or the transition from the street as you approach a driveway.
ARCHITECT – A tradesman who designs and produces plans for buildings, often overseeing the building process.
ARCHITECTS RULE (ruler) – Three sided ruler with different scales on each side. Also referred to as a "scale."
ASPHALT - A dark brown to black, highly viscous, hydrocarbon produced from the residue left after the distillation of petroleum. Asphalt is used on roofs and highways as a waterproofing agent.
AUGER – In carpentry, a wood-boring tool used by a carpenter to bore holes
AGGREGATE Crushed stone, slag or water-worn gravel that comes in a wide range of sizes. Used to surface built-up roofs.
ALLIGATORING – A characteristic of asphalt which occurs during the aging process in which the loss of volatile oils and the oxidation brought about by solar radiation produces a pattern of cracks which resemble an alligator hide, because of the limited tolerance of asphalt to thermal expansion or contraction.
ASPHALT – A dark brown to black, highly viscous, hydrocarbon produces from the residue left after the distillation of petroleum, used as a waterproofing agent. |
