Thermal Insulation

Ability of the material to retain the passage of heat / cold. The Expanded Insulation Corkboard has the characteristic of low thermal conductivity combined with a slow and gradual release of this heat / cold to the interior / exterior of a dwelling (high thermal inertia). Therefore: more effective insulation.

Anti-vibration Insulation

The ability of a material when subjected to loads have a natural tendency to recovery (resilience) to help prevent the spread of vibration over a given surface to be transmitted to the contiguous space. The Expanded Insulation Corkboard has a recovery to the original thickness of about 98% which allows the application in these situations.

Acoustic Insulation

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

To reduce the sound level of percussion noises due to impacts on the slab, resulting from people movement, especially children, dragging furniture or falling objects, which are instantly transmitted to the lower floor, which constitutes a true curse of lighter construction, so bringing an elastic element between the floor covering and the slab like the Expanded Insulation Corkboard 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
