Cavity Fill Injection Foam

Cavity Fill Injection Foam provides an alternate solution to empty cavity insulation. It provides superior R-value at 4.6 R per inch and expands to ensure that there are no voids in the cavities. Installation is performed by pumping foam through holes drilled in block, brick, or any other material where cavities are filled. There is no need to tear down the walls to access the empty space. This provides builders with tremendous cost and time savings.

Traditionally used for block buildings, Cavity Fill Injection Foam can also be installed in existing buildings where no insulation currently exists. This provides a much more energy efficient and comfortable environment.

Cavity Fill Injection Foam is considered to be an alternate solution to empty cavity insulation. It will provide superior R value. One of the keys to the performance of this insulation is the ability to fill any voids that are present where many other insulation types cannot be used, including both new construction and existing structures, depending on the areas to be addressed. Another advantage of Cavity Fill Pump Foam is the reduced amount of time that it takes to install the insulation – much less than other types of insulation.

Cavity Fill Injection Foam has several different applications:

  • Block core fill
  • Inside the walls of existing homes
  • Open cavities or spaces

Benefits of Cavity Fill Injection Foam


Results of cavity fill injection foam insulation can be very dramatic. In addition to the cost savings that are a result of using less energy to heat or cool a building, there will be fewer hot or cold areas and the comfort in the building will be improved. This difference will be felt and appreciated by all occupants.
