Internal Floors
Internal Floor Insulation



Acoustic performance is the principle requirement, with both sound insulation and sound absorption being important considerations.

The sound absorption characteristics of our mineral wool insulation solutions make them ideal for use in internal floor build-ups.

We have a wide range of solutions which comply with sound related building regulations.


Why Mineral Wool?

  • Absorbent mineral wool significantly improves sound insulation, reducing the amount of sound energy transferred from one side of the floor to the other.

  • Our acoustic solutions are manufactured with a density in excess of 10kg/m3, providing compliance with sound related building regulations.
