American Thermal Window Products, Inc. is a family-owned and operated company that has been serving the Chicago area since 1981. Founded by Iver Johnson, a former detective, the company began as a small basement operation, focused on providing quality window and door products to local families. Over the years, American Thermal has grown, including the acquisition of Sahara Window and Door in 2009, which helped expand their offerings and reach within the community.
Today, American Thermal operates out of two showrooms — one in Chicago and another in Niles — and proudly continues to be a three-generation family business. The company is committed to delivering the best windows and doors available in the Chicagoland area. With a focus on quality and service, the Johnson family, including Iver's children and grandchildren, continues to uphold the founding principles of hard work and dedication to their customers.
American Thermal provides a comprehensive range of services tailored for residential, historical, high floor/multi-family, and commercial projects. They are certified distributors of various reputable brands such as Quaker, Pella, Marvin, and Andersen, enabling them to offer high-quality products for every customer need. The company also emphasizes a clear and transparent installation process, with an in-house crew that ensures professional service from the estimate to the final installation.
In addition to windows and doors, American Thermal also offers siding and gutters, solidifying their position as a one-stop shop for home improvement needs. Their commitment to customer satisfaction and the local community continues to be the driving force behind their business operations, making American Thermal a trusted name in the industry.
