H-Block Pipe Insulation Supports are a heavy density fiberglass which is molded into the form of a block. H-Blocks were designed to be utilized as a superior pipe support system and to prevent crushing and bottoming-out of the surrounding insulation. H-Blocks enhance the thermal and vibration control properties of the entire insulation system. H-Block fibers are oriented parallel to the direction of the pipe to provide proper deflection standards and high compressive strength.
Order pipe support blocks based on the thickness of the pipe insulation you are installing. For example if you are installing 2" thick fiberglass pipe insulation, use 2" thick H-Blocks.
The Fiberglass color made to fabricate the H-Blocks may be yellow or brown.
Please look at the diagram below to determine the number of pipe support blocks required and their placement.
