Pro-Shields are 360o thermal hanger shields designed to meet the broadest range of pipe support applications.  They provide a continuous section of insulation with factory applied jacketing meeting ASTM E 96A (maximum 0.02 perm) through a wide variety of pipe hangers for pipe systems operating between +20o F. and +1200o F.  The insulation and jacketing extend beyond the galvanized steel shield for a neatly sealed joint with the adjoining insulation.  Pro-Shields are suitable for use in any type of clamp as well as in band-type hangers and on flat surfaces.  To assure proper support in all situations, high density 450 PSI inserts are installed in units for 10” pipe with 1” insulation thickness and in all units for 12” pipe and larger.  Pro-Shields meet the MSS standard for a Type 40 shield per MSS SP-58, Paragraph 7.63 – 7.66.  Pro-Shields Meet ASTM E84 Standards Flame Spread-5-, smoke developed-5-.  Rounded shield corners on all commercial size units.
