The Carpet and Rug Institute, or CRI (www.carpet-rug.org) has updated their Carpet Installation Standard for 2011. This new combined standard replaces the old CRI-104 for Commercial and CRI-105 for Residential installations.

The CRI Carpet Installation Standard
The Carpet and Rug Institute now offers a new, combined standard for carpet installation in both residential and commercial settings. The combined standard, which replaces CRI’s 104 and 105 installation standards, is a definitive industry minimum installation standard, providing installers, retailers, specification writers, and building owners with principles and workmanship standards for residential installation, in addition to a detailed outline of proper procedures and terminology used in commercial specification writing, planning, layout and installation. The CRI Installation Standard also includes guidelines for floor preparation and installation in special areas, diagrams, and charts.
The CRI Installation Standard represents over 25 years of information-gathering and installation expertise compiled by the members of CRI’s Installation Issues Management Team, which comprises manufacturers, professional installers, and other interested parties.
The new standard is available to download directly from the CRI here.
