Air, Light and Efficiency Showing Influence of Sash Types and Building Design . Vertical and Horizontal Sections of 3-high Lupton Steel Sash, CounterbalancedType. *^Few parts with many functions^ 37 • AIR, LIGHT AND EFFICIENCY Pond Continuous Sash We originated Pond Continuous Sash, the first top-hung con-tinuous sash, to accomplish three results: I—To be Aveatherproof when open, thus giving ventilationregardless of weather. 2—To afford the greatest effective ventilating area in proportionto sash area. 3—To facilitate the control of air inlets and outlets of large area,as is often required in foundries and elsewhere. The weather proof feature is obtained by hanging the sashfrom the top, in continuous lines outside of all structural work,where it forms a transparent shed over a \-ariable opening. A steelangle overhangs the top edge, and stationary storm panels under-lap the ends, thus excluding rain in a slanting wind. See photo-graph, p.
