  1. If we are talking from the 50’s to the 80’s/90’s probably a large percentage of buildings are constructed using RAAC, because like everyone in the country, they look for a way to build it as cheap as possible. Also using RAAC for rooves means less sturdy support was needed for the support beams, because it was just a bit lighter per m2, which also means saving more money. But I have one, what I think an important, point. If the used this RAAC from the 50’s until the end of the 80’s/the early 90’s, and it has a life expectancy of around 30 years, then most of the buildings should have been replaced or retro-fitted.
