Acousticork cork underlay and agglomerated cork and rubber underscreeds are the materials responsible for the excellent insulation characteristics of the Zeitz Museum of Contemporary Art Africa in Cape Town.

Corkwall's composition makes it a natural thermal insulation material, eliminating thermal bridges and thus protecting a building from energy losses.

In contrast to impact sound, thermal insulation is the capacity of the material to resist cold or heat. By increasing the thickness of the underlay, the thermal resistance also increases. Cork acts as a natural insulation in spaces where underlays are installed because of its ability to maintain the temperature inside…

Cork's air filled closed cell structure enables inherent damping of structural noise transmission, such as step noise and impacts throughout the decking surface and consequently increased acoustic performance.

The capacity of a structure to prevent sound from reaching a receiving location. Sound energy is not necessarily absorbed; impedance mismatch, or reflection back toward the source, is often the principal mechanism.

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.

The air inside the cells makes it an excellent insulator, leading to very low thermal conductivity, over a wide range of temperatures.

Underscreeds & Wall Bearing

One of the main reasons for choosing an Heavy Mass Layer with cork is its ability to improve the acoustic and damping performance of different vehicles.
