A window whose frame members are made of aluminum, usually anodized or painted.

A window that project outwards, hinged from the top (head) frame member, usually operated by a crank mechanism.

A window that projects outwards, hinged from either the left or right jambs, usually operated by a crank mechanism.

Usually a wood window, with either vinyl of metal cladding on the exterior frame pieces.

A window whose frame members consist of some manufactured composite material, oftentimes a mixture of recycled wood and vinyl.

A window that slides vertically, with both the upper and lower sections operable.

A window whose frame members are made of glass fiber material.

A door usually made of wood frame members with a large glass area that swings either inwards or outwards.

Divider bars manufactured either between the pieces of glass in an insulated unit (usually called grids) or applied to the exterior surfaces of the insulated glass (usually called grilles). Grids and/or Grilles come in a variety of patterns and sizes.

The upper horizontal frame member of a window.

A window that projects inwards, hinged from the top (head) frame member.

The glass in a window, consisting of two or three individual lites of glass, separated by a spacer and hermetically sealed.

The left and right vertical frame member of a window.

Glass that is actually two separate lites of glass sandwiching a layer of some type of polyvinyl butyral. Windshields are an example of Laminated Glass. Laminated glass can be used as safety glazing as well as to help reduce sound transmission.

“Low Emissivity” Glass. A type of glass where metal coatings are manufactured onto or into the glass which makes the glass more energy efficient.

The vertical frame member of a Horizontal Sliding window that divides the fixed section from the operable sash, or the horizontal frame member of a Single Hung window that divides the fixed section from the operable sash.

Fixed Portion of a Horizontal Sliding Window (XO, OX).

A window that slides horizontally, with a fixed section and a vent (operable) section.

Generally refers to the operable section of a window.

A window that slides vertically, with a fixed section and a vent (operable) section.

The amount of radiant energy transferred from the outside of the window to the inside, during warm climate conditions: The lower the SHGC, the less radiant heat transfer, and thus the more energy efficient.

A measurement of a windows ability to reduce noise from exterior sources. The higher the STC measurement, the more sound is reduced.

Glass that is strengthened by a heating a cooling process. All doors have tempered glass.

Thermal transmittance of energy through the window, measuring the amount of warmer interior air that transfer through the window during cold climate conditions. The lower the U-value, the less thermal transfer and thus, the more energy efficient.

A window whose frame material is made primarily with vinyl.

An engineered system to allow water to drain to the outside of the window.

A window whose frame material is made primarily with wood.

Operable Portion of a Horizontal Sliding Window (XO, OX).
