Pool noodles are actually nearly identical to industrial and residential foam insulation for pipes, the only difference being the industrial use version of the technology is a denser foam and has a structural reinforcement outer layer. People have used pool noodles as cheaper versions of the industrial pipe insulation inside buildings at a substantial cost savings, as the industrial version is about twice to four times as expensive.

Medieval warfare LARPs often make extensive use of pool noodle with such cores for foam weapons. It is generally the least expensive form of construction available and very easy to make into a safe weapon, however pool noodle foam is more prone to break down with extended use than other types of foam.
