Sound absorption is the ability of a material to absorb the sound waves transforming them into energy and releasing only a remnant. This difference between the absorption capacity and the initial value of the noise results in an acoustic insulation. The Expanded Insulation Corkboard can be used as material for the correction of acoustic environments (sound absorption), and when in a constructive solution, as an important acoustic insulation.
Acoustic Correction of an Environment
The Expanded Insulation Corkboard is indicated for treatment of a particular acoustic environment, reducing noise level, the effect of absorption and acoustic treatment of halls, concerts, meetings or other, where one wishes to reduce its reverberation time . See Graph>
Acoustic Insulation for Airborne Noise Transmission
Normally the lining of the roof of a room with Expanded Insulation Corkboard is sufficient to dramatically improve its acoustics. When it comes to rooms with specific purposes that need a determined reverberation time, it is needed to check the conjugation with low frequencies absorbent materials because they are not simple materials capable of absorbing both high and low frequencies.
Impact Noise Insulation
ThermaCork can reduce the sound level of percussion noises due to impacts on the slab, resulting from people movement, especially children, dragging furniture or falling objects. These noises are instantly transmitted to the lower floor, which constitutes a true curse of lighter construction. Hence, bringing an elastic element, like ThermaCork, between the floor covering and the slab will be required.
The system takes its name of floating floor screed since the screed constituting the floor itself will be entirely separate from the slab or walls, staying at "float" on a layer of Expanded Insulation Corkboard.
