Heavy Density Pipe Insulation is a heavy density, preformed insulation composed of fine, stable and uniformly textured inorganic glass fibers bonded together by a non-water soluble and fire- retardant thermosetting and heat resistant resin. It is free from coarse fibers and shot due to it’s mineral compositions, molded in one piece sections and made with a single seam. Heavy Density Pipe Insulation are damage resistant, easy to handle and spread open to receive the pipe and snaps closed after placement.


Heavy Density Pipe Insulation is intended for use in commercial, institutional, industrial and residential construction and in power and process plants as thermal and acoustic insulation for hot or cold, concealed or exposed steel, copper and plastic piping where temperatures are between -18°C and +450°C (0 to 850°F).
