Insulation Screen, Ingersoll Steel & Disc Division Borg-Warner Corporation 310 So. Michigan Ave., Chicago, Illinois Distributors ill the Principal Cities * Siut Screen"It's cooler in the shadeV* A Metal Fabric That Reduces the Solar Load Through Windows as much as 80 to 85 Per Cent. KOOLSHADE Sun Screen has had such ready acceptance among Air Conditioning Engineers because it offers high ef ficiency in cutting down the Solar Load without shutting off light or vision. Its advantages are: (1) Lowers the cost of cooling equipment necessary by stopping 80 to 85 per cent of the Solar heat outside the window glass. (2) Saves in operating cost-- as much as 25 to 50 per cent, where there are large windows. (3) Reduces the need for zoning for sun effect. (4) Forestalls com plaints due to extreme sun heat. (5) Maintains lower temperatures in noncooled rooms. *THIS WINDOW equipped with KOOLSHADE no direct sun comes in but ample light. ^THIS WINDOW is bare--and shows how the sun rays stream into the room. Automatic Sun Shade. KOOLSHADE is always in position ... functions automatically ... protects most when most needed. The flat hori zontal wires, held at a FIXED angle of 17 deg, fully stop direct heat rays when the sun is 38H deg or more above the horizon--the heat of the day in all seasons. Needs no adjustment or human attention. Light and Vision. KOOLSHADE gives sunexposure rooms the effect of cool "north" light, free from glare. Vision from within is superior to that through windows with 18-mesh fly screen. Actual photo of KOOLSHADE installed. Stops direct Sun Heat . . . kills Sun Clare . . . with abundant light and clear vision . . . yet it is practically invisible! Attractive Appearance. Makes the window look smart, and does not mar the outside appear ance of the building. 1050 Ingersoll Steel & Disc Division Insulation Screens Economy. KOOLSHADE is strong, tough and should last for many years. Maintenance cost is negligible and first cost is low. Other Advantages include full insect protection, free ventilation, reduction of fading of fabrics and fire-safety. Specifications of Fabric. Made of fine quality bronze, with 17 horizontal wires per in. and vertical wires spaced l/; in. apart. Supplied in widths up to 72 in. Framing and Installation. Framed and installed like ordinary insect screens. Frames may be either wood or metal-- always full length and always outside the window glass. Re-wiring of present screen frames is entirely practical. Where to Buy. Authorized KOOL SHADE distributors and dealers in all principal cities offer adequate facilities to assure correct frame design and proper installation. Technical Proof of Performance. Reports of Tests and Calculations by the Pittsburgh Testing Laboratories provide ample evidence as to the performance of KOOLSHADE. A full copy of this report (from which one table is reproduced below) will be sent upon request for Brochure HG102. For Full Literature and information, write for our Booklet HG101 entitled "KOOLSHADE SIJN CONDITIONING." Framed and Installed like ordinary fly screen -- and keeps out in sects, too.
