Improving Energy, Environment & Economics.

Introducing 3E Plus® software. Calculate the appropriate insulation thickness—every time—for any application quickly and easily.

Make the Easy Choice

Determining the appropriate amount of insulation can be tricky. But we’re making it easy. Calculating thickness is a critical part of the success or failure of an insulation system. And with 3E Plus®, you calculate what you need—where you need it.

Our new, innovative, game–changing software ensures accuracy with customizable inputs for every aspect of your job. Insulation selections are based on K–values from ASTM material standards. We also provide data from every major insulation manufacturer, so you can easily use the K–values of the specific material you are considering.
