A Glossary of Terms for Replacement Windows

When talking to a contractor or retailer about replacement windows, or just reading brochures, it pays to know the jargon in order to better understand window construction and to be better prepared to ask the right questions. The following is a glossary of terms that will help make your search for the right windows more productive. Familiarize yourself with them before you begin shopping.

Air infiltration: air leakage around the mating parts of the window’s frame, usually measured in cubic feet per minute per square foot of frame area (cfm/sq ft).

Aluminum clad: a window type that consists of a wooden frame covered in pre-painted aluminum sheet to better resist the elements. Some windows are vinyl clad for the same reason.

Air space: the space between the inner and outer panes of double or triple-glazed windows.

Argon gas: a colorless inert gas used between the inner and outer panes of a multi-glazed window in order to reduce heat loss. Some windows use krypton gas instead of argon.

Awning windows: a style of window that is hinged at the top so that the sash can swing outward for ventilation.
