Crest Hill's climate zone, in plain terms
Chicago-Naperville-Elgin, IL-IN runs a January average near 24°F and climbs to about 75°F by July, a swing that adds up to roughly 6,063 heating degree days most winters, with 947 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Crest Hill, separate from anything a brochure claims.
Zone 5A's requirement is the floor; Crest Hill's specific load is what tells you whether beating that floor is worth the extra cost.

What FEMA's risk data says about Crest Hill
FEMA rates Will County's hurricane risk as Very Low and its wind risk as Relatively Low.
Neither rating changes a window's energy label, but both are exactly what impact-resistance and design-pressure ratings are built to answer for a Crest Hill home.
Ask specifically about design pressure and impact rating for Crest Hill, not just energy performance, if either risk rating comes back on the high side.
- Hurricane
- Very Low
- Strong wind
