Hingham, MA Climate Specs + Top-Rated Window Installers
ENERGY STAR groups Plymouth County into its Northern zone, the U-factor and SHGC target worth checking against any quote you get in Hingham. Below that spec discussion sit 7 installers, their order set by Google rating, since Hingham is outside this site's window license file. A high rating is worth a look, not a finished decision.

Hingham's climate zone, in plain terms
Boston-Cambridge-Newton, MA-NH runs a January average near 30°F and climbs to about 73°F by July, a swing that adds up to roughly 5,688 heating degree days most winters, with 726 on the summer cooling side of the ledger.
That load is the actual argument for paying up for a better U-factor in Hingham, separate from anything a brochure claims.
Zone 5A's requirement is the floor; Hingham's specific load is what tells you whether beating that floor is worth the extra cost.

What FEMA's risk data says about Hingham
FEMA rates Plymouth County's hurricane risk as Relatively Moderate and its wind risk as Relatively High.
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 Hingham home.
Ask specifically about design pressure and impact rating for Hingham, not just energy performance, if either risk rating comes back on the high side.
- Hurricane
- Relatively Moderate
- Strong wind
- Relatively High
- Winter weather
