A Microbial Resistance Evaluation of Indoor Materials

air krete® Insulation Sample

Executive Summary / Project Description
Air Quality Sciences, Inc. (AQS) is pleased to present the results of its microbial resistance evaluation of air krete's indoor material identified as “ air krete® Insulation Sample”. AQS conducted this study using a microbial test protocol following the requirements of ASTM Guideline D 6329-98 (1). This ASTM method is established to study indoor materials for their ability to support mold growth. Testing of the indoor material was conducted using static environmental chambers operating at 75% humidity
(considered a *high normal” for indoor commercial spaces) and 95% humidity (considered an extreme moisture condition within buildings). air krete's indoor material was inoculated with two representative indoor molds, Stachvbotrvs chartarum and Eurotium amstelodami, and growth rates were measured over a three-week period as the materials were exposed in the two humidity environments. Mold growth is considered significant if it exceeds 20% of the initial baseline levels. Test methodology
and results are given in the attached summary reports.

Results
Results show that the “ air krete® Insulation Sample” was resistant to mold growth at both 75% and 95% relative humidities. Neither molds were found to amplify in the materials at either humidity.
