The process by which air leaks into a building. In either case, heat loss results. To find the infiltration heating load factor (HLF), the formula to account for the extra BTU's needed to heat the infiltrated air is:
(Impact Noise Rating). A single figure rating which provides an estimate of the impact sound insulating performance of a floor-ceiling assembly.
In roofing, a drain positioned on a roof at some location other than the perimeter. It drains surface water inside the building through closed pipes to a drainage system.
Insulating Glass Unit
Two or more lights of glass spaced apart and hermetically sealed to form a single-glazed unit with an air space between each light. (Commonly called IG units.)
(1) Generally, any material which slows down or retards the flow or transfer of heat. Building insulation types are classified according to form as loose fill, flexible, rigid, reflective, and foamed-in-place. All types are rated according to their ability to resist heat flow (R-Value). (2) In electrical contracting, rubber, thermoplastic, or asbestos wire covering. The thickness of insulation varies with wire size and type of material, application or other code limitations.
A rigid structural building board made of coarse wood or cane fiber in - and 25/32-inch thickness It can be obtained in various size sheets, in various densities, and with several treatments.
Any of several specialized mechanical fasteners designed to hold insulation down to a steel or a nailable deck.
Material used to cover the interior framed areas, or materials of walls and ceilings
Glazing infills set from the interior of the building.
