St. Louis Park's climate zone, in plain terms
St. Louis Park falls in IECC climate zone 6A, and ENERGY STAR separately groups Hennepin County into its Northern 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 St. Louis Park.
A Minneapolis-St. Paul-Bloomington, MN-WI 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 4.3 mi away.
What FEMA's risk data says about St. Louis Park
Hennepin County's hail risk sits at Very High and its wildfire risk at Relatively Low, according to FEMA's National Risk Index.
Hail risk matters for glass and screen durability in St. Louis Park; 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 St. Louis Park installer before you settle on a product line.
