Thinsulate insulation

Hey All,
Can Thinsulate be used as insulation on the walls and ceiling? I’d use something else on the floors. I’ve seen so many videos on this and am totally unsure in this area. There’s a British guy who’s vids I keep going to more and more for reference. He used Earthwool Dritherm Mineral Wool Cavity Slab and Kingspan Therma PIR Foil Faced Insulation (floors/some walls/ceiling) in his build. Just needed a few more opinions.

The quick answer is yes. Thinsulate can be used as insulation on the walls and ceiling.
