Mechanical Insulation Design Guide

MIDG logoWhether you are looking for basic insulation information or need to design a complex insulation system, the Mechanical Insulation Design Guide (MIDG) is the best resource. Designed to assist the novice or the knowledgeable user alike in the design, selection, specification, installation, and maintenance of mechanical insulation, the MIDG is continually updated with the most current and complete information.

An insulation designer’s basic questions can be summed up as follows:

  • Why am I insulating this?
  • What am I insulating?
  • Where am I insulating and what are the ambient design conditions?
  • What materials and systems are best for this job?
  • How much will this cost and what is the best way to implement this solution?

The MIDG is divided into sections that answer each of these questions:

Users will also find a product selection chart, searchable by temperature, and simple calculators:

MIDG also links to NIA’s MTL Product Catalog, the only online library of technical literature for the insulation industry, searchable by product or company. The MTL Product Catalog makes the most up-to-date product information available to MIDG users in one convenient place.

MIDG was developed by the National Institute of Building Sciences and the National Insulation Association with contributions from 15 organizations, 60 manufacturers and fabricators, and 12 contractors, as well as the involvement of more than 100 individuals. MIDG is intended to be an unbiased, comprehensive, living document and vertical portal resource to assist specifiers, facility owners, and other users of mechanical insulation systems for a wide range of industrial and commercial applications.
