Original 1946 window trade vintage catalog for the BORG-WARNER CORPORATION. (Ingersoll Steel Division). Main office and plant were located at 310 South Michigan Avenue, Chicago, IL.

Manufacturers of Ingersoll KoolShade Sun Screen.

KoolShade Sun Screen is, any effect, a bronze outside miniature venetian blind with louvres permanently slanted outward and downward at a 17° angle, to block, reflect, absorb and radiate as much as 90% of the sun's heat rays, outside the window! Yet unlike other shading devices, KoolShade does its work without shutting off light, view or ventilation.

KoolShade is even more practical than air conditioning because it keeps the heat outside. It's always easier to plug up the leak than it is to keep bailing out the boat!

Has product image, illustration, description, application and specifications provide product details.

Unbound from a large rare 1946 Architectural Catalog, this unique old four-page technical brochure would display beautifully matted and framed. Nice graphics. A fabulous addition to your retro window industry library.
