Mechanical Insulation Design Guide - Update Summary

by the National Mechanical Insulation Committee (NMIC)

The National Institute of Building Sciences (NIBS) through the National Mechanical Insulation Committee (NMIC) has developed the Mechanical Insulation Design Guide (MIDG) to provide a comprehensive source of information on the performance, use, testing and standardization of mechanical insulation in buildings and industrial facilities. The MIDG is continually being improved and updated. Any edits, revisions, updates or interest in adding new information should be directed through the 'Comment' link on the respect page. Disclaimer.

This Update Summary is being provided as a simple guide to provide MIDG users a quick reference of the most recent updates to the applicable MIDG Sections. Minor corrections, as determined by NMIC, may not be included. Users should not rely solely upon this summary to denote all MIDG modifications.
