Versico's labor-saving VersiFleece Fire-Rated (FR) TPO membranes are manufactured using a hot-melt extrusion process for complete scrim encapsulation. Once the TPO is reinforced and enhanced with 10-ounce fire-resistant fleece, the total sheet thickness is 115-mils, creating a durable sheet that is quick to install and ideal for re-roofing or new construction projects.
