<p>A system (10) for providing multi-paned glazing lights (16), primarily for use as insulated glazing units in door and windows, employs noble gases for filling the insulative spaced enclosed between the glazing panes. The system (10) uses the glazing light or lights (16) as a gas flow manifold, mounted within a sealed vacuum chamber (12), for evacuating the chamber (12) and the one or more glazing lights (16) located therein. The glazing light, or lights (16), then also serve as the gas flow manifold for filling the lights (16) and the surrounding exhausted chamber (12) with the required noble gas. The system (10) operates at room temperature, and enables selection of the internal pressure of the noble gas within the glazing units, in accordance with predetermined factors such as the altitude of the ultimate site where the lights are destined to be used. The lights (16) are sealed off within the vacuum chamber (12), prior to removal therefrom, while in a controlled environment. The system enables consistent, extremely high gas fillings such as 97% noble gas, in a relatively rapid, economic and ecologically conservative manner. <IMAGE></p> |
