Expanded clay

Lightweight aggregate that thanks to its cellular structure closed in a hard shell optimizes the weight/resistance ratio. Laterlite expanded clay insulatas and does not deteriorate in time. It can be used in the creation of permanent thermal insulation works. Is “Euroclass A1″, according to the Fire Prevention Standards. Baked at 1200 °C it is practically indestructable even in disastrous fire. It is used as a raw material for fire-proof or refractory products as it is classified as absolutely incombustible. Thanks to its outer compact and resistant shell, Leca has a great compressive strength. Laterlite granules stick together with a low dose of cement, forming lightweight grout which is great for supporting the loads used on foundations and non-structural construction components (floors, partition walls, supports). Laterlite expanded clay does not contain, nor releases silica, fibrous substances, Radon gas or other harmful materials, not even in the e vent of fire. It is a natural and environmentally-friendly product.
