Description / Features

PP-R Pro-Shields are 360o thermal hanger shields custom cut for Perfect ID match to metric PP-R OD’s. They are designed to meet a broad range of pipe support applications while providing a continuous section of insulation and factory applied jacketing meeting ASTM E 96A (maximum 0.02 perm) through a variety of pipe hangers. These units are appropriate across the entire PP-R temperature range.  On all units the insulation and jacketing extend beyond the galvanized steel shield for neatly sealed joint with the adjoining insulation.  Units are suitable for use in any type of clamp as well as in band-type hangers and on flat surfaces.  PP-R Pro-Shields meet the MSS standard for a Type 40 shield per MSS SP-58, Paragraph 7.63 – 7.66.
