Floating Floor Mounts and Perimeter Strip
A concrete floor that floats on rubber mounts, separated from the structural slab and the walls around it, so noise and vibration from a mechanical plant room stay out of the rooms below and beside it.

Mounts and perimeter strip
Both are available to buy online from Fixing Smith, our group company’s store.
AFR-RFloating Floor Rubber Mount
Carries the floating slab on four raised corner columns, so it deflects evenly even under uneven loads.
AFR-RM: 135 kg, 6 mm · AFR-RL: 325 kg, 10 mm · 70 Shore A as standard

AFR-PSPerimeter Strip
Keeps the floating slab off walls and columns along its full height, so sound cannot bypass the mounts.

The system
How a floating floor is built
- Structural slab
- AFR-R mountsSet out on a grid; spacing from the floor load.
- Mineral wool between the mountsOptional, at the installer’s or designer’s choice.
- Plywood deck on the mounts
- Separating membrane between plywood and concreteStrongly recommended.
- Reinforced concrete floating slabTypically 100 mm.
- AFR-PS strip at every wall and columnFull height of the slab.
In practice, a floor built this way reaches a natural frequency of around 15 Hz.
