Founded in 1991, Dritherm International Inc. was established to manufacture and distribute DriTherm™ as the ideal balance of thermal and cost efficient field applied underground insulation. Prior to 1991, an identical formula was sold and distributed in North America as Protexulate beginning in the late 1960’s. The founder of Dritherm International and former Protexulate Inc. salesman brought DriTherm™ to market as the ideal replacement for Protexulate and to continue expanding the underground pour-in-place market. This unique formula has the single longest track record for field applied underground insulation on the market today.
