ABSTRACT:
A method of efficiently using fiberboard (10) for insulating pipes (16) carrying high temperature fluids. Semicylindrical pieces (12) are cut out of the board, with the legs (14) of the cut pieces having a length approximately five percent longer than necessary. When these pieces are installed on a pipe, the additional material is compressed mainly near the ends of the legs (where the fibers are radial to the pipe). This selectively increases the density where required for efficient insulating purposes. In addition, a better sealing of the joints between adjacent legs is accomplished.
