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

What zone 3B means for a Spring Valley window
Las Vegas-Henderson-North Las Vegas, NV runs a January average near 48°F and climbs to about 93°F by July, a swing that adds up to roughly 2,017 heating degree days most winters, with 3,563 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Spring Valley, separate from anything a brochure claims.
Zone 3B's requirement is the floor; Spring Valley's specific load is what tells you whether beating that floor is worth the extra cost.
