How does an installer know when a CMU or stud wall is full?
Sensitive temperature and pressure gauges are located in strategic locations throughout the Tripolymer® foam installation system. As the cavity being filled reaches completion, a small amount of back pressure is produced. Once this pressure reaches a predetermined point, as monitored through the gauges, the installer stops the process and proceeds to the next access hole. A backup method, known as ‘fill time’, is also used. An experienced installer knows 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 drilled above or below the blockage.
