Soundproofing Floors Using Acoustic Mineral Wool
To reduce sound travelling between floors, a cavity is created using joists and then filled with fibre insulation. The floor height is raised slightly depending on the method but no more than 18mm.
Acoustic Mineral Wool
Acoustic mineral wool is a high density fibre used for filling cavities and absorbing sound. You may have heard of products such as Rockwool or other forms of insulation, this is a very common product used for soundproofing.
