3E Plus Tool

Johns Manville partnered with NAIMA to bring you customized 3E Plus® software specific to JM products.

With JM’s 3E Plus tool, you can tailor your inputs for every job and get the specification details for the JM pipe insulation products you want to use. The 3E Plus software calculates the necessary insulation thickness for your application using the unique variables you input based on the needs of your system.
