The Carpet and Rug Institute (CRI) has published a new, combined standard for the installation of residential and commercial carpet, called the CRI Carpet Installation Standard 2011.

The combined standard, which replaces CRI’s 104 and 105 installation standards, covers 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 standard also includes guidelines for floor preparation and installation in special areas.

A free, 36-page PDF copy of the standard is available on CRI’s website at by clicking on the Carpet and Rug Industry tab, then clicking on Installation Resources.
