Swatara's climate zone, in plain terms
Swatara falls in IECC climate zone 4A, and ENERGY STAR separately groups Dauphin County into its North-Central zone for window certification.
Those two numbers, not the brand on the box, set the U-factor and SHGC worth checking on any quote you get in Swatara.
A Harrisburg-Carlisle, PA contractor who can't name either one on request is worth a second question before you sign.
Data: U.S. EPA / DOE, ENERGY STAR, ENERGY STAR Version 7.0 Climate Zones by County/ZIP (Windows, Doors, and Skylights) (V7.0); Pacific Northwest National Laboratory (DOE Building America), Guide to Determining Climate Zone by County: Building America and IECC 2021 Updates (PNNL-33270) (2021 IECC), from the nearest NOAA station 3.2 mi away.
What FEMA's risk data says about Swatara
Dauphin County's hail risk sits at Very Low and its wildfire risk at Very Low, according to FEMA's National Risk Index.
Hail risk matters for glass and screen durability in Swatara; 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 Swatara installer before you settle on a product line.

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.
