INTRODUCTION
Introduction
The Air Duct Council Flexible Duct Performance & Installation Standards (Greenbook) was first introduced to the HVAC industry in 1980. This standard has been the installation and performance guideline for the flexible duct industry for many years. This edition seeks to make it easier to locate topics of interest for installers, inspectors, designers and homeowners. Each chapter addresses a specific interest, but it was written in a way that is easy for anyone to follow and understand regardless of background or expertise in HVAC.
