Anyone in the building trade in the early 1970's ??
Can you identify what this insulation is made from in the attic of an ex council house built about 1973 in SE London
It looks like gravel
It has the consistency of dried porridge oats
It's very light
Some of the flakes seem to be silica based (as you get rainbow colours in direct light)
It has white wooly bits mixed in with it (which may be from a later covering ?)
