Fire Protection Research Foundation report: "Sprinkler Insulation: A Literature Review"
Author: Brian Merrifield
Date of issue: July 2011
Recent research and experience with antifreeze in home fire sprinkler systems has resulted in limitations on its use in this application. This literature review was conducted at the request of NFPA’s Technical Committee on Residential Sprinkler Systems. Its scope is to identify and gather all pertinent articles that have been published in relation to the use of insulation within residential facilities to protect sprinkler piping from freezing conditions.
