General Suburban Updates and Rumours

[plam]

One more comment about common walls: we need better standards for these. There should be a standard to which they can be built which actually does in fact eliminate sound transmission entirely (probably by actually building the two buildings separately so there is an air gap, then closing in the sides and top so airflow doesn’t remove heat from the combined block); then townhouse and apartment developers could advertise this and people could be confident that they don’t have to worry about hearing their neighbours through the walls.

I've looked at my common wall while doing renos, but didn't know exactly what I was looking at. There is certainly an air gap, but there is no cladding obviously. In general our common wall is fairly good but not perfect.

For some townhouse configurations ceilings/floors are more of an issue.
