Chapter 6 Flashcards
The amount of heat loss or gain that occurs by infiltration through the cracks and openings in a window assembly
Air leakage (AL)
A portion of an interior rising above adjacent rooftops, with windows admitting daylight
Clerestory
A number from 1-100, the higher the number, the greater resistance to condensation
Condensation resistance (CR)
Many small panes in a window each in its own frame
Divided lights
Design and placement of windows in a building
Fenestration
Sheets of glass made to set into frames
Glazing
Thin transparent coatings of silver or tin oxide applied to one glass surface facing the air gap that allow the passage of visible light while reflecting IR head radiation back into the room, reducing the flow of heat through the window
Low-emittance (Low-E) coating
Narrow window or pane of glass set alongside a door or larger window
Sidelight
The fraction of solar radiation admitted through a window both directly transmitted and absorbed and subsequently released inward
Solar heat gain coefficient (SHGC)
A separate sash added to a single-glazed window
Storm window
High performance windows that utilize features such as multiple layers of glazing, multiple low-e coatings, and low conductivity gases
Superwindows
Small window above a door or other window
Transom
A device using a light shaft that provides surface reflection, capped with a clear skylight
Tubular daylight device (tubular skylight)
Fraction of the visible spectrum of sunlight, weighted by the sensitivity of the human eye, that is transmitted through the glazing of a window, door, or skylight
Visible transmittance (VT)
To apply a strip of rubber, metal, or other material to seal the edges of a door or window
Weatherstripping
