Adjustable: Accessible without major reconstruction of the window, door, TDD, SSP, roof window, or unit skylight to bring the parts of the product to a true or more effective relative position.
Architectural terrace door: a door primarily used for terrace access in high-rise applications/buildings.
Note: Architectural terrace doors consist of one or more glazed panels contained within one master frame. The operable panels will be hinged on either jamb and can swing either to the exterior or interior (not both). The door is not used as a primary entrance door because of the nature of the sill/threshold design used to meet performance requirements.
Building envelope: the assembly or assemblies of materials and components that enclose building spaces and are exposed to exterior space or separate conditioned interior space from unconditioned interior space.
Combination assembly: an assembly formed by a combination of two or more separate fenestration products whose frames are mulled together utilizing a combination mullion or reinforcing mullion.
Commercial entrance system: a system of products used for ingress, egress, and rescue generally in non-residential buildings.
Note: Commercial entrance systems typically utilize panic hardware, automatic closers, and relatively large amounts of glass. Commercial entrance systems are often site assembled. They are typically subject to high use and possibly abuse and are designed to withstand such use and abuse.
Composite unit: a fenestration product consisting of two or more sash, leaves, lites, or sliding door panels within a single frame utilizing an integral mullion.
Note: Composite units are not to be confused with products made from cellulosic composite materials.
Conditioned space: an area or room within a building that (a) is heated or cooled by any equipment or appliance; (b) contains uninsulated ducts; or (c) has a fixed opening directly into an adjacent area or room that is heated or cooled by any equipment or appliance or contains uninsulated ducts.
Design pressure (DP): a rating that identifies the load, induced by wind and/or static snow, that a product is rated to withstand in its end-use application.
Note: Design pressure (DP) is not to be confused with Performance Grade (PG) or structural test pressure (STP). Loads induced by static snow are applicable only to TDDs, roof windows, and unit skylights.
Divider: a member that divides glazing into separate vision areas. Dividers are either structural or decorative. Other common terms are muntin, true divided lite (TDL), simulated divided lite (SDL), grill, grid, or bar-in-glass.
Door: a means of access for the purpose of ingress and egress. See also Commercial entrance system, Dual-action side-hinged door, Folding door system, Interior door, Passive door, Revolving door, Secondary storm product, Side-hinged door system, Sliding door, Storm door, and Vehicular-access door.
Double Weatherstripping (STANDARD FEATURE): A material that has two or more levels of flexibility. An example is the weatherstripping used between the frame and sash of a casement window.
Dual-action side-hinged door: a door system consisting of one or more leaves contained within an overall frame and designed such that one of the leaves is operable in a swing mode and can be tilted inward from the top for ventilation.
Dual mode: the primary and secondary window/door, or both primary windows/doors, are closed, the primary windows/doors are locked, and the insect screen (when offered or specified by the manufacturer) is in the stored position.
Fixed window: a window that is designed to be non-operable and consists of a glazed frame or a non-operating sash within a frame.
Note: This category does not include non-operable unit skylights or TDDs, or products fabricated from curtain wall or storefront systems that are used in window openings.
Float glass: flat glass that has been formed on molten metal, commonly tin. The surface in contact with the tin is known as the tin surface or tin side. The top surface is known as the atmosphere side or air side.
Folding door system: a door system that has, at a minimum, a hinge or pivot attachment of any type between two leaves and three vertical axes about which the leaves rotate. The leaves can be folded to the interior or exterior of the opening. These systems are either top hung or bottom supported by hardware that attaches to a single track system and include, at a minimum, two pivoting/folding leaves, a frame, and a track and roller assembly. The frame has vertical and horizontal members that are joined at the intersections that fully encompass the operating and inactive leaves in a closed position. A flush set track assembly can exist in place of a sill assembly. Additional hinged and pivoting/folding leaves and/or a single-side hinged leaf can be included in the door system.
Fully tempered glass: glass that has been heat treated to a high surface and/or edge compression to meet the requirements of ASTM C1048 (kind FT) or CAN/CGSB 12.1.
Note: Fully tempered glass, if broken, will fracture into many small pieces (dice) which are more or less cubical. Fully tempered glass is approximately four times stronger than annealed glass of the same thickness when exposed to uniform static pressure loads.
Gateway performance requirements: the requirements for minimum gateway test size, air leakage resistance, structural design load and overload testing, water penetration testing, forced-entry resistance, and auxiliary testing which are the conditions permitting a product entry into a Performance Class.
Greenhouse window (garden window): a window consisting of a three-dimensional, five-sided structure, with provisions made for supporting plants in the enclosed space outside the plane of the wall. Operating sash are allowed but are not required.
Heat-strengthened glass: glass that has been heat treated to a specific surface and/or edge compression range to meet the requirements of ASTM C1048 (kind HS).
Note: Heat-strengthened glass is approximately two times as strong as annealed glass of the same thickness when exposed to uniform static pressure loads. Heat-strengthened glass is not considered safety glass and will not completely fracture into many small pieces (dice) as with fully tempered glass.
Horizontal sliding window: a window that consists of one or more sash that slide or roll horizontally within a common frame and can also contain fixed lites/sash.
Note: Typically, operating sash are identified with an (X) and fixed lites or fixed sash are identified with an (O).
Hung window: a window consisting of vertically sliding sash which utilize counterbalancing devices to allow the sash to be opened to any variable position between its fully open and fully closed limits. See also Vertical sliding window.
Note: Common types are single hung, double hung, and triple hung.
Insulating glass (IG) (STANDARD FEATURE): Also referred to as a insulated glass unit, or IGU, a combination of two or more panes of glass with a hermetically sealed air space between the panes of glass. This space may or may not be filled with an inert gas, such as argon.
Integral ventilating system/device: an apparatus that is independent from but installed into a window, door, or unit skylight product for the purpose of controlling the transfer of air through the window, door, or unit skylight product.
Interior accessory window (IAW): a glazed frame and/or sash, attached inboard of existing prime windows, curtain wall, or storefront, in commercial buildings, to enhance control of thermal transmittance, solar heat gain, sound, air leakage, and/or daylight. IAWs are not intended for occupant operation or to be used with the exterior windows in the open position, nor are they intended to provide any specific resistance to air leakage or water penetration, or withstand structural load.
Note: The IAW frame is typically anchored to surrounding construction, to the existing window frame, or to the curtain wall or storefront interior frame. Unlike SSPs and multiple glazing panels, interior accessory windows are intended for use by trained custodial personnel only and are fitted with limited-access custodial locks to hinge or lift out for periodic cleaning of the non-hermetically sealed air space created. If IAWs are intended for regular occupant operation, or used with the exterior windows in the open position, the product should instead be rated as a prime window or SSP.
Jal-awning window: a window consisting of a multiplicity of top-hinged sash arranged in a vertical series within a common frame, each operated by its own control device which swings the bottom edges of the sash outward. See also Jalousie window and Tropical awning window.
Jalousie window: a window consisting of a series of overlapping horizontal frameless louvers which pivot simultaneously in a common frame and are actuated by one or more operating devices so that the bottom edge of each louver swings outward and the top edge swings inward during operation.
Limited water (LW) (as a designation): that the water penetration resistance performance is achieved by testing at a pressure less than the minimum test pressure required for the indicated Performance Class and Performance Grade (PG).
Mortise-and-tenon: A strong wood joint made by fitting together a mortise in one board and a matching projecting member (tenon) in the other. Often used as a corner joint in window sashes.
Multiple glazing panel (MGP): a glazed panel that can be installed in or on a sash, leaf, or panel on either the interior side or exterior side of the primary glazing. An MGP is tested only in conjunction with a specific primary window or door.
