March 26, 20233 yr I pulled back a layer of pink glass fibre to get to a cable and found this stuff. It's pre-1989 I think, when the house was reroofed from slate to tile as there's broken slate in it.
March 26, 20233 yr May be yellow glass wool. Waste product was ground to make fibres that were injected into cavity walls and blown into lofts. Can you see individual fibres?

Can you see individual fibres? Thanks, I had another look today and yes it's got the shiny glass fibres in it. Will it have the same insulating properties as the glassfibre rolls in the loft or do I need to remove it and replace with other insulation? It's only in patches of the loft so looks like it's been taken out from the rest.
