John Eifler is the Principal architect with Eifler & Associates Architects in Chicago.
Join us for our next Window Hero Webinar and deepen your appreciation for Frank Lloyd Wright windows as well as the value of preserving historic homes.
Indow window inserts are interior storm panels designed to increase energy efficiency and comfort while preserving historic integrity by gently pressing into existing window frames. They simply press into place without a mounting bracket using our patented silicone Compression Tube. Always custom fabricated to fit out-of-square and special geometry windows, Indow inserts are ideal for beautiful historic windows.
