PROJECT NO: 4140 92-2757 DATE: July 23, 1993 <br /> PAGE: 2 <br /> FI��1AL TEST RESULTS <br /> EXPA:VDED POLYSTYREi�IE THER1titAL ni 1SULATION PERFOR1�iCE <br /> Pi 1 A BELOW-GRADE APPLICATION <br /> INTRODUCTION: <br /> lfiis report presents the results of a three year evaluation of the thermal performance of expanded <br /> polystyrene (EPS) insulation in a below-grade foundation application in a cold climate environment. The <br /> EPS was manufactured to meet the physical property requirements of ASTM-0578 (Standard Specification <br /> for Preformed, Cellu�ar Polystyrene Thermal Insulation). <br /> The scope of the study was limited to: . <br /> _ _ <br /> 1. Evaluating EPS insulation applied to the below-grade foundation of Twin City Testing's Cromwell <br /> Ave building in St. Paul, Minnesota. <br /> 2. Conducting tests on control samples to determine density, thermal resistance reference values, as <br /> well as to document compressive and flexural strength (see Appendix A: TCT Repo�t !� 4141 89- <br /> 659, dated 9-27-89). ' <br /> 3. Subsequently, for three years beginning October, 1990, removing a set of samples and conducting <br /> tests to determine density, thermal resistance, and moisture content of the EPS foundation insulation <br /> (see Appendix A: TCT Report #4141 90-0022, dated 11-1-90, TCT Report �t 414191-0878, date� <br /> 10-31-91, and TCT Report /t 4140 92-2757 data supplement, dated 5-10-93). <br /> 4. Documenting temperatures, annual precipitation, and soil moisture content (see Appendix B). <br /> . <br /> .1j A\1VTUAL pAOTECT�ON'O CVENTS rr,E PUBUC ar+0 OURSElvES �ll TWIN CITV TESTING CORPORATIQN HEPORTS ARE SUBMiT,TED AS THE CONFiOENT1AL?ROPERiv�.�:�'-E:' <br /> aVD aUTHOaiZailON FQR�UBUCaTION Of STaTE��EvTS CONCLUSiONS OR ExTa,�CiIONS FROM OR REGAROiNG OUR aEPORTS iS aESERVED PEvDING OUR PRIQR Wf?ITr=r�a�?���: <br />
