The Thermal Insulation Association of Canada (TIAC), Canada’s national association overseeing quality and standards for mechanical insulation, has partnered with the Midwest Insulation Contractors’ Association (MICA) to bring a national standards manual to Canada.

North American Commercial and Industrial Insulation Standards (NACIIS) Manual – Canada’s only standards manual for mechanical insulation – is now available for purchase. During the initial stages of updating its Best Practices Guide (BPG) in 2017, TIAC’s Innovators Group quickly realized important similarities between the BPG and the Midwest Insulation Contractors Association (MICA) manual, then called National Commercial and Industrial Insulation Standards or “MICA manual”.

In late 2021, TIAC finalized an agreement with MICA to endorse the manual, and the 9th edition—renamed the North American Commercial and Industrial Insulation Standards (NACIIS) manual—is now available.

The NACIIS manual contains updated information related to the design, specification, and installation of thermal insulation on piping, fittings, ductwork, equipment, and vessels found within commercial heating/ventilating/cooling and plumbing systems.

Industrial power and process systems information on firestopping systems is also included, and refrigeration and cryogenic systems have been added.

The manual is published as a service to contractors, engineers, designers, owners, and mechanical insulation industry. This resource has grown to be recognized as the authoritative source for specifying and communicating installation details for mechanical insulation systems across the United States and Canada.

The NACIIS Manual is currently only available in English. The next phase of TIAC’s agreement with MICA is to have the manual translated to French for use across Canada.
