Yes, it is. Expanded Clay Aggregate (ECA) is very useful for the construction of concrete wall panels in projects of any size, for several reasons. First, ECA is a very durable and lightweight material, so it enhances the strength-to-weight ratio of concrete when used as part of the concrete aggregate.
Beyond this, ECA also has superb insulative properties, due to the unique, void-filled structure of each individual pellet, which makes it difficult for heat transfer to occur. In addition, ECA also is inert and fire-resistant, and as a highly-porous material, it offers unparalleled sound-absorbing capabilities. Best of all, ECA products are affordable and easy-to-use, making them perfect for every project.
