Expanded Clay
Expanded clay nodules are produced by sophisticated pyrogenic technology whereby geochemically specific clay is expanded in a rotary kiln at a specifically controlled temperature and rate of flow. Each individual clay nodule is composed of hundreds of minute air cells contained within a hard, strong, ceramic shell. As an aggregate, TechniClay is incredibly light, strong, totally inert and when used in block production, transfers the same benefits giving excellent thermal, acoustic, strength and fire resistance characteristics.
