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 metals or fibres that are coated with adhesive liquid to which
particles of lint and dust adhere
Alligatoring - Pattern of cracks when paint or aged asphalt loses volatile oils and oxidized from solar
radiation - results limited tolerance to thermal expansion or contraction
Asphalt - Used on roofs and highways as a waterproofing agent
Batt insulation - Strips of fiberglass or rock-wool insulation with various thicknesses that fit between
studs or framing. May or may not have a paper covering.
blister - Enclosed raised spot on the surface of a building cause by expansion of trapped air, water
vapour, moisture or other gases
BTU (British Thermal Unit) - The amount of energy needed to heat one pound of water one degree
Fahrenheit
Collar - In roofing, a conical metal cap flashing used in conjunction with vent pipes or stacks, for the
purpose of shedding water away from the base of the vent.
, Condensation - Caused when warm moist air comes into contact with a colder object
What is a conductor in roofing? - A pipe to convey rainwater from the roof gutter to a drain or storm
drain.
What is the purpose of a conductor in roofing? - To channel rainwater from the roof gutter to a drain or
storm drain.
Electrical conductor - a wire through which a current of electricity flows
Conduction - flow of heat from one part of a substance to another.
Corrosion - the deterioration of a metal due to a chemical or electro-chemical reaction resulting from
exposure to weathering, moisture, chemicals, or other agents or media
Curb - a short wall or masonry built above the level of the roof that provides a means of flashing the
deck equipment
Damper - Valve for controlling air flows
Dampproofing - An application of a water-resisting treatment or material to the surface of a concrete or
masonry wall to prevent passage or absorption of water or moisture while still permitting moisture
vapour to escape from the structure. Can also be accomplished by using an admixture in the concrete
mix.
dew point - The temperature at which vapour condenses from the atmosphere and forms water
