Logan Square – Chicago, Illinois

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 Chicagoans, many of whom have been with us for decades.

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.
