Mechanical Insulation Design Guide (MIDG)
The MIDG includes the design, specification, installation, and maintenance of insulation systems for use within the markets defined above. Specialized insulated air handling products (flex-duct and duct board products) are not considered to be mechanical insulation industry from the perspective of this guide and accordingly are not addressed.
MIDG is part of the National Institute of Building Sciences Whole Building Design Guide (WBDG). The Whole Building Design Guide is an evolving web-based resource intended to provide architects, engineers, facility managers, project managers etc. with design guidance, criteria and technology for "whole buildings". The WBDG is continually augmented with updated and new information and is structured as a "vertical portal", enabling users to access increasingly specific information as they navigate deeper into the site. The Mechanical Insulation Design Guide has been developed within the same principles as the WBDG.
