Generally, termoarcilla blocks are ceramic bricks made from clay and secondary aggregates (typically expanded polystyrene beads or other granular materials). These secondary aggregates play a key role in manufacturing: during firing (at temperatures exceeding 900 °C), they undergo a gasification process that creates pores in the material, reducing the block's density and making it lightweight (hence why in some countries they are commonly called lightweight clay blocks). This porous structure enhances the block's thermal and acoustic insulation performance, offering significant advantages over similar materials.
