What it is

A soft break in the path.

Footsteps, dropped weights and machines shake the structure. That vibration travels through floors and walls and comes out as noise in the room below or next door.

Bonded foam is made from foam pieces pressed together into a dense, springy sheet. Laid between two hard layers, it breaks the direct contact, so less vibration gets through.

Use it under a floor, or as a backing layer with mass loaded vinyl in a wall or ceiling.

Good to know: bonded foam reduces sound passing between rooms. It won't reduce echo inside the room. For that, add our panels.

Where it goes

When the noise comes through the floor.

Flats & upper floors

Softer footsteps for the people living below.

Gyms & fitness studios

Dropped weights and jumping that don’t shake the floor below.

Home theatres

A floated floor that keeps the bass from travelling through the house.

Plant & machine rooms

Pumps and generators that don’t hum through the building.

Also used behind mass loaded vinyl in walls and ceilings, in studios, dance floors and under stages.
