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

Meridian's climate zone, in plain terms
Boise City, ID runs a January average near 32°F and climbs to about 77°F by July, a swing that adds up to roughly 5,321 heating degree days most winters, with 1,045 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Meridian, separate from anything a brochure claims.
Zone 5B's requirement is the floor; Meridian's specific load is what tells you whether beating that floor is worth the extra cost.

What FEMA's risk data says about Meridian
Ada County's hail risk sits at Relatively Low and its wildfire risk at Relatively High, according to FEMA's National Risk Index.
Hail risk matters for glass and screen durability in Meridian; 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 Meridian installer before you settle on a product line.
- Strong wind
- Relatively High
- Winter weather
- Very High

The order below weighs a Google rating against its review count, the same way this site weighs a U-factor against a brochure claim: on the number, not the name. Treat it as a rating, never as proof of a license, bond or HVHZ approval.
