Polypropylene has natural insulation properties, both for sound and for heat. This gives aquatherm’s pipes performance properties that aren’t possible with other systems.
For sound, polypropylene absorbs vibrations, allowing the pipe to run at 8 ft/s while generating the same noise as copper pipe at 3.5 ft/s. aquatherm also doesn’t require vibration isolators, provided there is some limited mobility of the pipe on either side of the pump.
