Performance Analysis of Aged TPO Membranes - Jennifer Keegan, GAF
| Description |
New TPO roof membranes have been extensively analyzed in laboratories, roof farm fields and under accelerated weathering conditions. Today, there are TPO roofs in the United States that have been in service for nearly 20 years. This paper will review the long term performance of a large sampling of field-aged TPO roof membranes installed throughout the US and evaluate 1) field-aged TPO roof membrane performance and 2) the ability to repair field-aged TPO roof membranes.
