Thermal Conductivity of Weathered Polyurethane Foam Roofing.

Abstract:

An investigation of the decay in the thermal conductivity of polyurethane foam PUF with time is presented. The polyurethane foams studied included samples removed from sprayed PUF roofing systems on structures at Guam, Marianas Islands Subic Bay, Republic of the Phillipines Denver, Colorado Clifton, New Jersey and Port Hueneme, California. Thermal conductivity results closely agree with those predicted for a foam aged at 25 C in a controlled atmosphere. Results also indicate that the foam can provide good insulation characteristics in spite of poor application. Author
