Sensitive temperature and pressure gauges are located in strategic locations throughout the Homesulate™ foam installation system. As the cavity being filled reaches capacity, a small amount of back pressure is produced. The process is monitored through gauges. Once this pressure reaches a predetermined point, the installer stops the process and proceeds to the next access hole. In addition, a backup method, which we refer to as 'fill time', is also used. Our experienced installers know the time it takes to fill a specific size and shape cavity. If the pressure reaches the completed level before the normal fill-time has elapsed, a blockage may have occurred, and additional access holes are then drilled above or below the blockage.
