By double brick do you mean a "full brick" wall that is as thick as one brick is long or a cavity wall with a air cavity? Both have pretty terrible insulation,

Both have pretty terrible insulation, basically negligible and i can't imagine anyone is building modern wood framed buildings with worse insulation. Even 5 cm of rockwool has 4 times the insulation value of a basic cavity wall, 6 times as much as a full brick wall.
With a cavity wall the outer layer is not structural so it's not really sturdier.
I'd take modern wood frame construction or aerated concrete with insulation and a brick veneer over a cavity wall or a full brick wall any day.
- sokoloff 4y agoI live in a 1920s full brick house in New England. The insulation in the unrenovated spaces is poor, but the mass of brick has the effect of modulating summer temperatures to a reasonable level of comfort without AC for most of the summer. It takes about 4 consecutive days in the high 80s/low 90s before the house gets uncomfortable. Winter gets and stays colder 24 hours a day, so heating costs about $450/mo for December-March. This place will likely be here largely as-is 100 years from now.
- yourusername 4y agoWe've been having regular long summer heatwaves in the Netherlands the past 10-15 years where it stays 30c+ for over a week. At that point the thermal mass of the brick starts working against you in the summer as well as the short nights (less than 8 hours in summer) are not enough to cool the house down and the brick radiating heat keeps the house uncomfortably warm 24/7.
- sokoloff 4y agoTrue. We’re about 10° farther south (than Amsterdam) so we get a slightly longer night in summer, but most importantly we run the window shaker ACs for that week which allows the house to be bearable.
