I have a undergrond pipe 60' long and 8" in diameter that has two 1 1/4 hot water pipes inside of it. I need to insulate this pipe to save some heat loss. Not sure if i could use loose blown in insulation, or should i use a
icyene product. Not sure if either can be blown that far into the pipe. Both ends are accesable.
Also ther are two vynal pipes, which i can pull
one out, it could be used to deliver foam or loose insulation into pipe.
