Even more successful than the Jalousie salesman of the 1950s & ’60s were those responsible for the aluminum sliders that followed.
Here, a 1930s Spanish house in Glendale lost many of its original window sash.
Metal windows like this slider conduct greater heat gain & loss than the wood sash that originally sat within this jamb.
Because the window is south-facing, the homeowner wanted to maximize the insulating quality of the window. Though it may be hard to tell from the photo, the new Douglas Fir sash replicate an original window in material and design, but are dual-glazed.
The home’s period character is restored and the homeowner is more comfortable in summer.
