"Where Honesty & Integrity Are Not Just Lip Service, But A Tradition"

Cool-Temp Siding & Window Company is one of the largest and oldest family owned and operated Home Improvement companies in Texas and Oklahoma. Edward L. McAlvain, a native Oklahoman, founded Cool-Temp Siding Company in 1961. Mr. McAlvain was the first to provide USS Steel Siding as a permanent solution to the painting needs of area homeowners.
