Vandalia's Climate Data and Its Top-Rated Window Pros
ENERGY STAR groups Montgomery County into its Northern zone, the U-factor and SHGC target worth checking against any quote you get in Vandalia. Below that spec discussion sit 10 installers, their order set by Google rating, since Vandalia 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 Vandalia window
Dayton-Kettering-Beavercreek, OH runs a January average near 29°F and climbs to about 76°F by July, a swing that adds up to roughly 5,149 heating degree days most winters, with 1,154 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Vandalia, separate from anything a brochure claims.
Zone 5A's requirement is the floor; Vandalia's specific load is what tells you whether beating that floor is worth the extra cost.
