Foam insulation for a masonry wall expands to help fill every available space and leaves no gaps for noise or heat to travel through. It is noncorrosive and contributes no toxic chemicals or particulates to the building’s interior. It is easy to install and costs less than current methods. By those definitions, foamed-in-place insulation is very close to ideal. Whether injected into the cells of a block wall or into the cavity of a veneer wall, the foam fills all open spaces and can result in R-values as high as 20.
Doing the job right involves the following steps:
- Evaluating the wall to determine where foam can be injected and how to ensure that the foam fills all empty cells, cavities, and gaps in the wall.
- Drilling injection holes into one face of each wall to create openings into the block cells at the bed joints.
- Injecting the foam
- Cleaning and patching the injection holes.
Foam insulation does not settle and will not run out if a hole is cut into the wall, and it does not interfere with mason productivity.
Foamed-in-place insulation works equally well to improve thermal and acoustical performance in new or existing construction.
The great advantage of a foamed-in-place system is that it creates a very complete insulating fill of the gaps in a wall, achieving a huge improvement in the thermal and sound performance over a hollow wall and even a slight advantage over granular insulating fills.
