And that's not a new thing either. In my 1970's house we have 150mm insulation under the house from the original build, 150mm in the walls and 200mm on the roof. We added another part to the house a few years ago, and that was 300mm insulation in floor/walls/roof. Since the walls are made of brick with a depth of 7cm, it means the walls are 7+7+30= 44cm thick (plus some "slack") Even my 1980's summerhouse has 100mm insulation in floor/walls/roof. |
