WMP-VRR Fiberglass Insulation Facing
WMP-VRR is the most commonly installed insulation facing in metal buildings. The front side is composed of a polypropylene insulation facing, with a metallized polyester (foil like) backing on back side. WMP-VRR Plus provides a higher permeability than WMP-VR. It is generally used in a typical metal building that does not require heavy facing. WMP-VRR Plus insulation facing is available in white or black.
