What zone 5A means for a Brookfield window
Brookfield falls in IECC climate zone 5A, and ENERGY STAR separately groups Waukesha 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 Brookfield.
A Milwaukee-Waukesha, WI contractor who can't name either one on request is worth a second question before you sign.

Hail risk matters for glass and screen durability in Brookfield; 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 Brookfield installer before you settle on a product line.
