Does cavity wall insulation reduce condensation? The single biggest direct impact of having dry CWI properly installed is that it raises internal wall temperatures above dew point temperature and therefore reduces the risk of cold surface condensation damp.
Does cavity wall insulation cause condensation? Condensation can also occur as a result of having cavity wall insulation. Cavity walls are used to reduce the amount of heat escaping the property, however, if there are gaps in the walls this will mean the walls remain cold.
How do you stop condensation on a cavity wall?
