Continuous insulation made simple for Basements!

InSoFast Panels for basement insulation is the fastest and easiest way to frame and insulate your basement. Whether you are an experienced contractor or a first-time DIY’er, InSoFast panels are the right choice for your project.

Illinois was originally home to Indigenous peoples including the Illiniwek Confederation, Miami, and Potawatomi. French explorers established settlements in the 1600s, and the region became part of the United States after the Revolutionary War. Illinois entered the Union in 1818 as the 21st state. Its fertile prairies attracted farmers, while Chicago’s location on Lake Michigan and near major rivers made it a vital center of trade and industry. During the 19th century, Illinois played a key role in westward expansion, railroad development, and the abolition movement. Abraham Lincoln, who lived much of his life in Illinois, rose to the presidency from here. The state’s industrial base expanded in the late 19th and 20th centuries, drawing immigrants and fueling Chicago’s growth into a major metropolis. Today, Illinois is recognized for its cultural diversity, political influence, and economic strength.
