insulation of Engines exhausts

IN YOUR 3rd SENTENCE, CHANGE EMITTED TO RADIATED. DUE TO THE THERMAL CONTAINMENT PROPERTIES OF THIS PRODUCT, "EMITTED" TEMPERATURES CAN ACTUALLY BE SEEN TO RISE, WHILE INVERSELY, "RADIATED" SHOULD BE LOWERED, BASED ON THICKNESS OR DEPTH OF LAGGING APPLIED. CAREFUL STUDY SHOULD BE APPLIED TO ANY INTERFACES BETWEEN METAL TO GRP/FRP OR METAL TO PAINTED SURFACES AS HIGHER EMITTED TEMPERATURES COULD INDUCE FAILURE OF THESE CONNECTIONS. IN A DRY STACK EXHAUST, STANDOFFS AND SUPPORT BRACKETS MAY NEED (FURTHER) INSULATION AND IN A WET EXHAUST, INJECTED WATER FLOW SHOULD BE MONITORED AND BE DETERMINED TO BE SUFFICIENT BEFORE THE PIPE/GRP, PIPE/HULL INTERFACE.

AS FAR AS THE CLAIMS MADE BY THE BUILDER, HAVE THEM PUT IN THE SPECS

Actually, the way I read the product spec, it reduces the surface contact temperature to 36-37 degrees celsius. Pretty important in an engine room, IMHO... less chance of a burn if hman flesh comes in contact with it, less chance of a fire in the case of a petroleum product leak.

The product looks pretty good to me, but then again I am not an engineer.

Not by name (the assumption being you already knew it), but by inference. (see 2nd sentence)

I stand rebuked.. Too too many hours in engine rooms, I do this in person also.
