hi can anyone tell me what sort of insulation this is, my boss at work thinks it's paper backed fiberglass. says it was put in outhouse about 35 years ago. it looks like fiberglass to me but it's completely grey and its paperbacked. has anyone else seen this type of insulation. did fiberglass insulation ever have asbestos in? or was it ever grey? Been working in this out house for about 3 years and the insulation is damaged all over. so a little concerned, my boss assures me it's fiberglass but would like a second opinion. if you go on screwfix forum and look at today's posts I've uploaded some photos can't work out how to do it on here

It is impossible to say whether something isn't asbestos just by looking at pictures, and impossible to say anything without seeing good quality close-up ones.

It seems the ones on the screwfix site are just thumbnails and you have to register and log in to see them in detail.

It looks like you are getting some advice there though.
