About TF Forming Systems and Insulated Concrete Forms


Founded in 1994 by Jerry Spude and Don Rudolph, TF Forming Systems is the manufacturer and distributor of VERTICAL insulated concrete forming systems (ICF): ThermoForm and a new revolutionary concrete forming system, TransForm. 

Our patented ThermoForm "plank & rail" system was originally designed to be installed horizontally, like all block ICF building systems are today.  We quickly realized that there were many additional benefits to standing our components up....Vertically.

Today TF, the original vertical ICF system manufacturer, is a leader in the ICF construction industry with a proven track record of innovation, successful installations and superior customer service.

Our Passion: Our company thrives on three core values:

Integrity: We have a passion for honesty, even if it isn't the answer we are hoping for.

Curiosity: Since getting started with Insulated Concrete Forms (ICFs), we've never stopped looking for better ways to build, seeking different perspectives, better answers, and generating usable, practical ideas to be used in the ICF construction field.

Commitment: It comes easy: we do what we say.
