Georgia Tech Research Institute (GTRI), Atlanta, recently conducted a study promoting new technology for hidden mold detection. Funding for this project was provided by the U.S. Department of Housing and Urban Development's (HUD) Office of Healthy Homes and Lead Hazard Control; the Air Conditioning and Refrigeration Technology Institute Inc. (ARTI); the Office of the Chief Scientist at Georgia Tech Research Institute; and Munters Moisture Control Services. Prepared for ARTI, "Portable Mold Sensors: Technical Feasibility and Operational Requirements," summarizes the operational requirements for a new mold detection technology and outlines the technical ability and feasibility of radar technology to detect hidden mold growth accurately and without causing wall damage.
One of the largest mold growth concerns is a vapor barrier. Trapping moisture underneath or between surfaces provides an ideal moist environment where mold can easily grow. The backside of wallpaper, drywall, and paneling can yield hidden mold, along with the top of ceiling tiles and the underside of carpeting and padding.
