CONCRETE SUB-FLOORS

Concrete floors, due to their high mass, have a high resistance to airborne sound but still transmit impact sound, therefore the need to reduce impact sound is a main priority.

A batten system (with the increased mass given by the chipboard) is an excellent method by which to both increase the
relative mass and introduce a resilient layer to absorb impact sounds.

  Attenu8 Battens Deep and Shallow
are robust Detail compliant (FFT1
and FFT3 respectively) solutions for
a variety of concrete sub-floors.

Battens are easy to install,
lightweight and allow space for
service voids.

Non-load bearing partitions can be
built off the finished floor.
