Circular, Cement-free and CO2 negative!

The Next Gen acoustic building blocks

Soundblox acoustic concrete blocks have been used for years as an acoustic solution wherever robustness and stability are as important as room acoustics. Soundless Acoustics now also supplies Soundblox in a new, carbonized variant, Carbstone, as a cement-free alternative to the traditional concrete variant. Given that cement is responsible for as much as 10% of global CO2 emissions, this represents a revolutionary breakthrough when it comes to sustainability and CO2 reduction! This makes Soundblox not only useful in the fight against noise pollution, but now also against CO2 emissions!

With Soundblox acoustic (concrete) blocks, the solution for sound absorption, sound insulation and fire resistance can be combined in one stable wall construction and room acoustics can be optimized in any room (both indoor and outdoor) where stability, impact resistance and fire safety are as important as (room) acoustics. Soundblox are available in various wall thicknesses.

Cradle to Cradle

Now Soundblox are also available in a new, carbonized variant, where they still have the advantages of concrete, but no longer the ecological disadvantages. This new acoustic carbstone looks just like traditional concrete blocks and has the same sound absorbing and insulating properties as the blocks made from traditional concrete. The carbonized blocks are equipped with identical special Helmholtz resonators for the absorption of sound, which is absorbed through the openings of the blocks and into the sound chambers behind them. A revolutionary development in the fight against CO2 as well as noise pollution! In addition to Soundblox, regular vision blocks are of course also available with this new technology.

Unlike traditional concrete blocks, however, these blocks are manufactured with CO2, which is specially extracted from the air and used in production. These blocks therefore absorb not only sound, but also CO2, thus intrinsically contributing to a better world. In addition, after installation (in the open air), they continue to absorb CO2 and become harder and harder so that their carrying capacity also continues to increase.

Revolutionary technology

This patented carbonation technology converts metal slag from the steel industry, which until now had no industrial use whatsoever, into circular and very high-quality building materials, using CO2 as a binder and making cement completely unnecessary. This carbstone is 100% recyclable. After production, these blocks are placed in a special CO2 chamber, where they are cured within 24 hours with minimal use of energy. The production process also makes maximum use of available solar energy to further reduce the ecological foodprint of the production process.

Versatile application

What has also remained the same is the versatile applicability of Soundblox, which, because of their ball resistance, stability and friendly prices, are gladly used in sports halls, but also in large warehouses, factories, swimming pools, hangars, etc. In addition, they are ideal for outdoor applications, for example, to create a sound barrier in front of houses and apartment buildings, right by the highway or at railway stations. Furthermore, Soundblox are excellent for use in areas with extreme temperatures or humid conditions, such as swimming pools. They are also increasingly used in schools, auditoriums, common areas of apartment buildings, libraries, concert halls and studios, where they quietly do their work without compromising the design of the interior.
