Fiberglass Blocks Supports
Product Data Sheet
DESCRIPTION
INSULATIOUN COMPONENT FIBERGLASS BLOCK SUPPORTS
are 18lb. cu./ft. density molded fiberglass which is light yellowish tan in color. 
Fiberglass Block Supports are designed to be used along with the IC Saddles
to ensure that the pipe insulation does not compress at each hanger location.
Fiberglass Block Supports enhances thermal and vibration control properties
of the entire insulation system.

RECCOMENDED INSTALLATION INSTRUCTIONS
INSULATION COMPONENTS Fiberglass Block Supports are placed inside the pipe insulation at ALL hanger location. Before applying the pipe insulation, simply notch out the insulation with a insulation knife and replace it with the appropriate sized fiberglass block support.
( SEE SIZING CHART FOR RECOMMENDED BLOCK SIZE) Proceed by applying the pipe insulation to the pipe and then inserting the appropriate IC Saddle.
ENGINEERING GUIDE SPECIFICATION
WHEREVER PIPE INSULATION PASSES THROUGH A HANGER LOCATION, THE FIBERGLASS BLOCK SUPPORTS SHALL BE INSTALLED WITH THE APPROPIATE IC SADDLE. ALSO, THE THICKNESS OF THE FIBERGLASS BLOCK SUPPORT SHALL BE EQUAL TO THAT OF THE PIPE INSULATION THICKNESS.
