Karma Acoustic Separating Floor Solutions

Karma Acoustic floor solutions are offered for timber, concrete and steel/concrete composite
floors. These are used to reduce the transmission of airborne sound and impact sound to comply with current acoustic Building Regulations. Karma Acoustic solutions are suitable for use in new build, refurbishment and remedial projects and can be complemented with a variety of floor finishes.

The range includes products for Robust Details and Pre-Completion Testing.

Airborne Sound Reduction

A separating floor is defined as any floor which divides one dwelling or residential room from another. Separating floors must provide a minimum level of airborne sound reduction to the amount of noise that televisions, speech and telephones etc. may create. When looking at airborne sound reduction results, the higher the performance, the more effective the solution.

Ctr Adjusting Factor

(currently applicable in England and Wales only)
Low frequency sound from home entertainment equipment is often present between adjoining properties in a separating floor application.

Therefore a correction factor is taken into account known as ’+Ctr’, which is the most narrow spectrum of sound that causes discomfort in the human ear.

All separating floors must provide one hour’s fire protection. Structural engineers should be consulted when adding high mass products to existing floors.

Impact Sound Reduction

Separating floors must provide impact sound insulation at source to reduce the amount of noise created by footsteps, furniture or heavy objects moving or hitting the floor. With impact sound the measurement scale is reversed therefore the lower the value, the more effective the solution.
