Hello! I removed these translucent plastic looking corrugated sheets from the bottom of the garden (recently moved in), on seeing the fibres photographed I then got worried that they could be asbestos. I appreciate difficult to say but does it look more likely to be fibreglass or asbestos? Thanks!

Hiya, please can you help me? These grey blocks are on the inner-side, with red brick on the outside, of a house built in 1987. I'm trying to find out what they're called? Many thanks in advance!
