NIA knows it can be difficult to find information on mechanical insulation so our members and staff have created and compiled the following resources. In order to help engineers, specifiers, and insulation contractors, NIA offers a number of free insulation technical resources. NIA’s Technical Information Committee (TIC) reviews and updates these documents quarterly. If you are interested in submitting product information or contributing, you may want to consider joining the TIC.
Insulation Materials Specification Chart 
The Insulation Materials Specification Chart, created originally for the NIA’s training programs, provides users with physical and material properties of various insulation materials as specified in ASTM Materials Specifications. This product, created by NIA’s Technical Information Committee, was created out of a need for an unbiased, easy-to-use selection guide to help course participants look up and study the physical and material properties of different types of insulations.

Guide to Product Specifications 
This NIA guide is a compilation of current ASTM, federal, and military specifications relevant to the insulation industry. It lists the companies that manufacture products that conform to each specification. This is a helpful publication for the insulation contractor, specifier, user, and owner.

Insulation Science Glossary
The Insulation Science Glossary contains a list of basic and advanced insulation industry terms and their definitions. It is reviewed quarterly by NIA’s Technical Information Committee.

Metal Building Insulation Resources
Get all your questions answered by the Metal Building Laminators or find out about Certified Faced Insulation. A revision to the NIA 404 Standard will be coming in January 2023.
The National Commercial & Industrial Insulation Standards Manual, also known as the MICA Manual, was developed by the Midwest Insulation Contractors Association (MICA). The newly updated 8th Edition is available both in printed and interactive PDF versions with 111 MICA Insulation Plates, including vapor dams and a new Cryogenic Section, and updated Materials Property Section with tables conforming to ASTM Standards.


ASTM International is an international standards organization that develops and publishes voluntary consensus technical standards for a wide range of materials, products, systems, and services.

Standard 90.1 has been a benchmark for commercial building energy codes in the United States and a key basis for codes and standards around the world for more than 35 years.

The ICC is dedicated to developing model codes and standards used in the design, build, and compliance process to construct safe, sustainable, affordable, and resilient structures. The International Codes®, or I-Codes®, published by ICC, provide minimum safeguards for people at home, at school, and in the workplace. The I-Codes are a complete set of comprehensive, coordinated building safety and fire prevention codes.

MasterSpec®, a product of the American Institute of Architects (AIA), is the ultimate resource for producing specifications your way. With master guide specifications, delete what doesn’t apply, add your own customizations, and rest assured that your specs are current and complete.

Process Industry Practices (PIP) is a coalition of process industry owners and engineering construction contractors who serve the industry. PIP was organized in 1993 and is a separately funded initiative of the Construction Industry Institute (CII), at The University of Texas at Austin. PIP publishes documents called Practices. These Practices reflect a harmonization of company engineering standards in various disciplines. One of these disciplines is coating and insulation and includes design, selection and specification, and installation information. Visit to learn more.
