  GLOSSARY OF TERMS

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.
