New Version of 3E Plus® Available for Download

The North American Insulation Manufacturers Association (NAIMA) announces that an updated version of the 3E Plus® computer software, version 3.2 of the program, is now available for download at

When downloading the new version of the software, current users of the software should register their name as "current user." How do you know if you already have version 3.2? Simply open the 3E Plus® program. Click on "help" menu, then "about" and the window will display which version of the program you have installed. Most users have version 3.1 or lower. Print the installation directions and follow them during installation - the install program will replace the current version of the program. It is important to note: any jacket or insulation materials you have added will be deleted and must be re-entered.

Version 3.2 of the program has the latest version of the ASTM C 680 heat transfer equations as well as several updated ASTM material thermal conductivity files.

NAIMA is currently working on a completely new version of the program that will include metric capability and greater flexibility. NIA members will be notified when it becomes available.
