You won’t know for sure whether it contains asbestos fibres unless you get it lab tested. To me it looks fibrous just like an asbestos-cement product. If the Asbestos content in the product is less than 14% it’s classed as Asbestos-cement and can be handled differently ( wet removal, p3 mask, paper suit etc ) compared to if it contains more than 14%. Now you’re talking full PPE, P3 Mask with blower, Work area to be encapsulated, negative pressure to prevent fibres escaping etc.., Showers for the workers and and and.
Be Warned! YOUR LANDLORD WILL NOT WANT TO GO DOWN THIS ROUTE IF HE HIS A ROGUE AS IT IS EXPENSIVE. Get some sort of official clearance.
IMHO it’s asbestos. firstly by looks, secondly It’s also very difficult to make products that have the same characteristics as asbestos ie. heat resistance in the same dimensions as an asbestos product. ie 5mm thick.
to clarify..a non asbestos product that is to deliver the same as an asbestos product needs to be thicker.
A few years ago I was asked to paint some soffits and after inspecting asked the lady to send a piece off to the lab. She said she’d spoken to this person, that person etc and it’s not asbestos. She’d spoken to the last decorator that had sanded and painted them and there is nothing to worry about. I still refused and told her to get the painter back that did them last time. Long story short lab result was asbestos.
