Can Expanded Clay Aggregate or ECA be used for Thermal insulating mortars & plasters ?

Expanded Clay Aggregate (ECA) can be added to mortars and plasters to enhance their thermally-resistant effects. ECA consists of tiny, lightweight clay “balls,” which can be as small as 0.5 mm.

Each ball has thousands of tiny holes, in a honeycomb structure, caused by the production process. These tiny voids help minimize thermal conductivity and make it difficult for heat to pass through each ECA ball.

By adding ECA to mortar and plaster for both exterior and interior use, builders can take advantage of these properties, minimize issues like thermal bridging, and create more efficient, comfortable structures.
