Palatine's Climate Data and Its Top-Rated Window Pros
ENERGY STAR groups Cook County into its Northern zone, the U-factor and SHGC target worth checking against any quote you get in Palatine. Below that spec discussion sit 10 installers, their order set by Google rating, since Palatine is outside this site's window license file. A high rating is worth a look, not a finished decision.

What zone 5A means for a Palatine window
Chicago-Naperville-Elgin, IL-IN runs a January average near 21°F and climbs to about 72°F by July, a swing that adds up to roughly 6,816 heating degree days most winters, with 652 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Palatine, separate from anything a brochure claims.
Zone 5A's requirement is the floor; Palatine's specific load is what tells you whether beating that floor is worth the extra cost.

Storm and weather risk around Palatine
Cook County's hail risk sits at Relatively High and its wildfire risk at Very Low, according to FEMA's National Risk Index.
Hail risk matters for glass and screen durability in Palatine; wildfire risk matters more for the frame material and nearby vegetation than for the glass itself.
Either way, it's a reasonable question to bring to a Palatine installer before you settle on a product line.
