WHY CLIMATE GUARD?

BUILT IN CHICAGO, FOR CHICAGO

Locally owned and operated, the ClimateGuard factory has been a fixture in the Logan Square neighborhood for over forty years. As the largest vinyl window manufacturer in Chicago, we employ more than one hundred local Chicago natives, many of whom have been with us for decades. In fact, we invite our customers to visit our factory to learn about our state-of-the-art manufacturing facility capable of producing top-of-the-line replacement windows.

WHAT SETS US APART

Unlike the big-box stores, our windows are designed and made specifically for Chicago. As lifetime residents, we know how challenging our weather can be, and high performance vinyl can make all the difference during those summer and winter months when energy costs can skyrocket. We’ve worked with industry leading engineers to develop vinyl technology 17 times more efficient than aluminum and will never rot or crack like wood. Our exclusive uShield glass units, designed specifically to complement our vinyl frames, deliver consistently superior uFactor ratings.
