We routinely conduct our own test of the stability of RetroFoam in various environments.  We want to know how it handles exposure to various elements and conditions. We cut samples of RetroFoam and store it in different environments. We are very pleased with RetroFoam’s stability, even when left outside at our barn naked to the elements.
