Acoustic insulation

Cork has low conductivity to noise and vibration. This is because the gaseous components contained in cork are enclosed in small impermeable compartments, isolated from each other by a moisture-resistant substance.

Day-to-day noises and footfalls in other rooms of the house spread easily. The installation of a cork underlay reduces the sound of footfalls both within the room and in the space below, in the case of installations on 2nd and upper floors, as it reduces impact as well as reflected walking sound. Cork underlays can mak…

Integrated in the dashboard, sun visors and doors, cork is a natural raw material that provides the German brand's car with comfort, water resistance, thermal and acoustic insulation, and anti-vibration.

Cork is the common denominator used in all our underlays. When applied beneath a flooring system, a cork-based underlay provides greater comfort, protection and longevity to the final floor, ensuring greater energy efficiency and better acoustic and thermal insulation.

Cork is a common denominator in the production of our accessories and supporting materials for floorings, such as, underlayment. When applied under a floor, an underlayment provides more comfort, protection and longevity to the final floor, guaranteeing even greater energy efficiency and acoustic insulation.

Mass Law provides a good working rule to predict the airborne Sound Insulation of a partition up to the region of the Critical Frequency and the coincidence effect. The coincidence effect occurs when the Wavelength of the sound in air is the same as the bending waves in the partition. At a certain frequency and angle o…

The growing demand of citizens for large urban centres mainly has to do with the incessant search for more satisfying living, conditions. This has given rise to the rural exodus. It became necessary to build upwards, as a result of this overcrowding. This gave rise to the first apartment buildings of small family homes…

The Underlays Plus and Plus VB Go4Cork by Amorim are produced using a mixture of cork with other by-products, based on the best principles of the circular economy. The underlays make a decisive contribution to the performance of the flooring solution, in terms of its load absorption capacity, acoustic insulation and hi…

The acoustic core materials developed by Amorim Cork Composites can be used to create innovative and more efficient interior systems in different modes of transport. Floor, side and ceiling panels are examples of applications in which cork's lightness and insulating capacity play an important role in the system's perfo…

A floor that contains at least two of our components will benefit from cork's acoustic high-performance, both in terms of noise insulation, for adjacent rooms, and in terms of internal comfort of the room, in which footfall noises are significantly cut down. Benefits will also be noted with regard to thermal comfort, a…
