What is maxit LWA?
maxit LWA was initially developed to provide insulation to roads, railways and ditches across Scandinavia. It is a lightweight expanded clay, formed by heating and firing natural marine clay.
The process transforms the clay into various sized lightweight ceramic granules, which have a hard ceramic shell and a porous core. In this form, the material has excellent insulating properties and is extremely lightweight with a bulk density of between 0.28 to 0.33 tonnes per cubic metre. These granules are also fire resistant, frost resistant and chemically inert with no hazardous properties.
