Am I right in thinking that the cavity wall insulatoion that is pumped in beads or foam cannot be used on cavity brick walls...???
Difference being cavity wall 2 separate walls parallel beng filled whereas cavty brick, only 2 holes at the top and they cannot be filled..
Am I wrong?
FIL got cavity bricks filled by insulation company, was he conned?
