Some 30 years ago I built a 12ft x 30ft shed/workshop from a load of
second-hand Uni-Seco panels scrounged from the demolition of old prefab
buildings at RAF Swanton Morley.
Being two layers of asbestos separated by a hardwood frame with some kind of
insulation filling the centre they made an excellent building. I roofed it
using some agricultural fibre and plastic corrugated sheets, the name of
which escapes me now. That building was still standing two years ago when I
last had contact with the folk that bought the house.
My thoughts now is did I inhale anything nasty when I cut them all down in
height with an electric saw? Was that insulation material some kind of nasty
blue asbestos?
When I did it I was oblivious of any danger from asbestos dust. As I was at
about 10 years old when I helped my grandfather wire brush clean some
second-hand asbestos sheets he was using to re roof his garage.
Not that I let it worry me, what is done is done...
