Argon
Gas
This odorless, colorless gas is
inserted between panes of glass for insulation and also increases a
window's energy efficiency by reducing conductive heat transfer. |
Low E
Glass
Windows that have been coated
with a transparent, metallic layer to the glass surface, reducing its
emissivity or ability to radiate heat. |
Awning
Window
This style of window swings
out from the bottom and away from a building, just like an
awning. |
Mulled
To join two windows or
doors together, side by side. |
Bay
Window
A three-unit window with a
center piece flanked by two side panels that are usually angled at 30 or
45 degrees. |
NCTL
Validated
National Certified Testing
Labs (NCTL) is an organization that performs standardized tests on windows
to ensure proper quality control levels. |
Bow
Window
A combination of windows
composed of four or more units, which are aligned in a smooth curving
contour.
Casement
Window
A window that swings open from
the side, hinging at the top and bottom of the frame. |
NFRC
Rating
The National Fenestration
Rating Council (NFRC) is a non-profit group comprised of manufacturers,
builders, designers, government officials, utilities and consumers working
together to provide unbiased energy performance ratings for windows, doors
and skylights (fenestrations). |
Double
Hung Window
Consists of top and
bottom vertically sliding sashes in a single frame.
Emissivity
The relative
ability of a surface to radiate heat. |
Nailing
Fin (Flange)
A strip of sheet
material either integral or fastened to a unit's frame, creating a flange.
This is a common method to install new construction windows and
doors.
Picture
Window
A large, fixed or stationary
window designed to provide a maximum viewing area without
obstructions. |
Frame
The outer components of
a window or door unit, consisting of a head jamb, side jambs, blind stops
and window sills, as applies. |
R
Value
Measure of a window's overall
resistance to heat transmission from different air temperatures on either
side of the glass. |
Fusion
Welded
A process of melting two or
more items together (i.e., a window sash and frame) via welding. |
Sash
A wood/vinyl perimeter
to support the glass of a window, holding it separately from the frame and
allowing some independent movement from the frame. |
Glazing
1) Act of fitting a
window or door frame with glass. 2) Installing glass into a window or door
frame. |
Single
Hung Window
A window system with only
one glass unit movable in the window pane.
|
Glazing
Bead
A long, thin piece of moulded
wood used to secure glass to the sash or frame of a window; silicone is
often used to create a seal between the glass and wooden glazing
bead. |
Slider
Window
A window that opens
horizontally.
Tempered
Glass
Plate glass with increased
strength due to a special heat-treatment for greater strength as a safety
glass.
|
Geometric
Window
Specialty windows customized
to fit a variety of shapes, such as starburst, gothic, colonial, etc.
within a door pattern. |
Thermal
Performance
A window's ability to act
as a barrier to the transfer of heat. |
Hermetically
Sealed
An airtight seal.
Insulating
Glass Comprised of two or more pieces
of glazing (glass) separated by hermetically sealed airspace for improved
thermal efficiency. |
Thermo-Edge
Spacer
A system where protected
insulated glass creates increased temperatures along the window's edges
and therefore reduces the potential for condensation on the glass
surface. |
Kickplate
Applied to one or
both sides of a door's bottom rail, this thin, polished metal plate is
used to prevent denting and soiling of the wood surface. |
Transom
An operating window
unit for specific use above a door or window. |
Laminating
Method of bonding
two or more layers of glass together using heat and pressure, with inner
layers of transparent plastic. This process provides one of the best
avenues to blocking ultraviolet rays. |
Weatherstripping
Material
used to provide a weather-tight seal between a window/door sash or
frame. |
