Expanded clay is a unique lightweight aggregate with versatile applications, the only “all in one” aggregate with sustainable use “everywhere”. Thanks to its unique characteristics, expanded clay has broad range of applications “everywhere”, like in the HOUSING, INFRASTRUCTURE and WATER MANAGEMENT. It’s well defined in several product specific harmonized European standards, and all declarations are done in accordance with approved European test standards.
Expanded clay lightweight aggregate can be used as a primary material in the mix design of low density building blocks and panels. There is no alternative material in the market that delivers structural integrity whilst having a density < 350 kg/m3 which assists in creating a very sustainable lightweight flexible building material. Expanded clay block and panel walls deliver lightweight, yet, robust building construction solutions, that are suitable for external walls, party walls, basements, partitions and inner leaf blocks offering the very simple inherent benefits of thermal mass, sound reduction and thermal resistance.
Expanded clay blocks are manufactured and declared to EN 771-3:2011+A1:2015 Specification for masonry units – Part 3: Aggregate concrete masonry units (Dense and lightweight aggregates).
The expanded clay wall element is supplied to the European market in various sizes from a small block to a large panel, various formats, supplied with varying appearance and aesthetics, where local building techniques will determine the nominal sizes.
