Wait, what? How can you know about r-values but not that every modern house built has cavity walls that can be/are insulated?[1] Even hundred-year old houses

Even hundred-year old houses can be insulated by DIY drylining. You'll lose about 10cm of floor space though. Sometimes there's even some government grants available for this[2]

- bluGill 10y agoI'm biased to US construction methods of course. Note that while bricks are themselves of a worse r-value than wood, but wood isn't actually a great r-value either. Note that bricks are not a strong as wood under tension. They do well under compression, but that is not all the loads to account for. Bricks are used in cities and commercial construction primarily because they do not burn and so you can use them as a safety barrier.
