A Microbial Resistance Evaluation of Indoor Materials AirKrete® Insulation Sample Executive Summary / Project Description Air Quality Sciences, Inc. (AQS) is pleased to present the results of its microbial resistance evaluation of AirKrete’s® indoor material identified as “AirKrete® 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 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). AirKrete’s® indoor material was inoculated with two representative indoor molds, Stachybotrys 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 significant if it exceeds 20% of the initial baseline levels. Test methodology and results are in the attached summary reports. Results Results show that the “AirKrete® Insulation Sample” was

resistant to mold growth at both 75% and 95% relative humidity’s.

Neither mold types were found to amplify in the materials at either humidity
