Climate Solutions Windows & Doors

Climate Solutions Windows & Doors is a vinyl window and door manufacturer that makes custom vinyl windows and patio doors in its own factory. Its lineup includes double hung, casement, bay, picture and sliding patio units, along with European tilt and turn windows and doors. The company cuts and assembles its own insulated glass units and can produce windows in any exterior color through its Full-Spectrum Color Lab.

Most of its sales go to contractors, dealers, architects and property developers rather than directly to homeowners, so most homeowners work with a window dealer who installs the products. The company has been named to Window+Door Magazine's Top 100 Window Manufacturer list and says its products carry a transferable Limited Lifetime Warranty. The factory is in Franklin Park, on the outskirts of Chicago.
