Rovanco's Pexgol Insulation System

Insulation for the underground installation of Pexgol piping & fittings system utilizes 10' lengths of split sleeve polyisocyanurate foam with HDPE outer jacket. Since lengths are split in half, they are to be applied in clam shell style and secured in place with mastic tape. It is very important all horizontal seams are completely sealed with mastic tape and should be done first. Then apply one wrap of tape in the approximate middle of the 10’ lengths and a full tape wrap on each joint seam where it connects to the next or previous length of insulation in the system. End of tape should overlap starting edge of tape by at least 2”. See installation instructions for more detail.
