Hillside's Climate Data and Its Top-Rated Window Pros

ENERGY STAR groups Union County into its North-Central zone, the U-factor and SHGC target worth checking against any quote you get in Hillside. Below that spec discussion sit 9 installers, their order set by Google rating, since Hillside is outside this site's window license file. A high rating is worth a look, not a finished decision.

Hillside's climate zone, in plain terms

Hillside falls in IECC climate zone 4A, and ENERGY STAR separately groups Union 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 Hillside.

A New York-Newark-Jersey City, NY-NJ 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 Hillside

FEMA rates Union County's hurricane risk as Relatively Moderate and its wind risk as Very 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 Hillside home.

Ask specifically about design pressure and impact rating for Hillside, not just energy performance, if either risk rating comes back on the high side.

Hurricane
Relatively Moderate
Strong wind
Very High
Winter weather
Very High
