ᐅ Non-woven wallpaper on the walls – which type to choose?

Hello everyone,

I have a question about wall finishing that I’m unclear about. I agreed with the painters on a Q3 level finish, a fleece, and a silicate paint. They haven’t started yet, but they have already delivered several rolls of glass fleece to the construction site.

I wasn’t expecting that; I thought fleece was made from cellulose or similar, so I’m a bit surprised. I will ask them about it, but I wanted to get your input first. Is this standard practice? What is the professional view on this?

Thanks, regards
GD
