Window or door in which two panes of glass are sealed with air space between. Also referred to as Double glass or Thermal Pane.
A glass unit using more than one piece, i.e. “double pane†or “double glazedâ€, “triple pane†or “triple glazedâ€.
Two pieces of glass spaced apart (with intercept spacer) and hermetically sealed to form a single glazed unit with an air space between.
(I.G.) A panel of glass comprising of at least two pieces of glass separated by a hermitically sealed air space. The most common method of achieving the hermetic air space is to prepare a spacer system of hollow aluminum bars that are filled with desiccant and placed between the pieces of glass, a sealant is then applied to the perimeter which will prevent moisture penetration and bond the unit together structurally. Also frequently called "double pane" glass.
