Climate and energy performance in Lancaster

Lancaster sits in IECC climate zone 4A, the starting point for any code-minimum window performance here.

ENERGY STAR places Lancaster County in its North-Central zone for window certification.

Normal temperatures run 31°F in January and 76°F in July, so the glass package worth paying for in Lancaster isn't the same one that pencils out two zones over.

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 1.5 mi away.

Google's top window installers serving Lancaster, PA

Ranked by Google rating weighted against how many people left one, so a perfect score from a handful of reviewers never outranks a strong average built on hundreds. That ranking is not a license check; call the state directly and ask for the contractor's license or registration number.
