This term is the sealed gap between the windowpanes in double or triple paned windows. It can be filled with air or another gas such as Argon or Krypton to help with insulation and noise reduction. The airspace should be between 1/2 and 3/4 inches thick or it will not work effectively.

The measured distance between the inner surfaces of the two pieces of glass in an insulated glass unit. Also used in reference to the thickness of the spacer bar. Ambient Temperature The outdoor temperature. American Architectural Manufacturers Association (AAMA) A window industry organization that establishes voluntary standards, certification to those standards, and designations. Angle Top Any window with a horizontal sill, vertical jambs, and a straight sloping head

All high performance windows have at least two panes of glass sandwiched together, with an airspace in between. The size of the airspace effects the overall performance of a window. A 1/2" to 3/4" space is considered optimal.

the atmosphere above a nation and deemed to be under its jurisdiction.

A three-dimensional space criss-crossed by airways. In keeping with lCAO (–) rules, worldwide airspace is subdivided into various classes. The provision of air traffic control is defined for each class, together with the applicable flight rules (– DELTA, Upper airspace). Distinction is made between civil and military airspace; each of these is primarily reserved for one user group. Since integration (–), skyguide manages all of Swiss and some foreign delegated airspace, and in so doing improves both flexibility of use and capacity.
