The acoustic insulation is the ability of a given product to retain or reduce the sounds and noises in between environments. The Expanded Corkboard – ICB, due to its properties is an excellent insulator, either in the acoustic correction, the Insulation from overhead noises or percussion noises.
The solutions that are presented are only informative.
It is of the utmost importance the strict compliance of the solutions and recommendation produced by the creators or owners of the several building systems.
Insulation from Overhead Noises
Insulation from overhead noise consists of reducing the transmission of noise produced outside or in adjoining rooms, which are propagated via the building structure (walls, flooring, doors and windows).
Acoustic correction consists of reducing the sound level in dB (decibels) of a given environment as well as reducing its reverberation time. Expanded Cork Board proves to be an Excellent material for the acoustic correction of certain environments, such as theatres, class rooms, concert halls, meeting rooms, etc.
The Expanded Cork Board reduces the sound level through absorption effects, allowing a reduction in the reverberation times.
Insulation of Percussion Noises
The insulation of percussion noises is the reducing of the sound level originated from the impacts on the slabs, which are transmitted to the immediately lower storey.
For an effective reduction, a total independence, between the flooring and the remaining structure, must be ensured.
The interposition of an elastic element, the Expanded Cork Board, between the flooring and the slab, makes a reduction in the transmission of vibrations and noises resulting from impacts.
It will also be important to maintain the discontinuity between the flooring screed and the adjoining walls, thereby eliminating marginal transmissions.
