Abstract:

This report describes the initial construction phase of a projected 2-year field evaluation of sheet-applied elastomeric ethylene propylene diene monomer EPDM roofs and liquid-applied elastomeric coating on sprayed polyurethane foam PUF roofs. This work is part of a research effort being conducted by the U.S. Army Construction Engineering Research Laboratory CERL to attempt to identify alternative, easy-to-install roofing systems that can improve the performance of Army roofing while reducing life-cycle costs. Sprayed PUF roofs coated with sprayed elastomeric material were installed on buildings at Fort Benning, GA Fort Knox, KY and Fort Lewis, WA. Sheets of EPDM synthetic rubber were installed on buildings at Forts Benning and Lewis. Built-up roofing systems were installed on buildings at Forts Benning and Lewis for control purposes. Thermocouples were installed below the insulation on all roofs, and thermocouples and strain guages were installed above the membrane on the EPDM roofs at Forts Benning and Lewis, so that a continuous record could be obtained of heat flows and membrane movement. Samples will be taken from all roofs every 6 months to 2 years for laboratory testing, and the roofs will be visually inspected every year for 10 years. Weather recording stations were installed at Forts Benning and Lewis so that roof temperatures and movements could be coordinated with ambient conditions. Author
