Airium™ is a mineral insulating foam technology. It is fully fire-resistant, long-lasting and sustainable. It can fill any type of shape and cavity, either on site or in an industrial controlled environment.


AiriumTM, insulation redefined

Airium™ is a fully mineral thermal insulation technology developed in the Research and Development center of LafargeHolcim in Lyon. It can be used in a simple way for many applications: from sub-screed floor insulation to the filling of concrete blocks (France and Austria are pilot countries for BlockFill) to roof terraces (in Morocco) and attics (ongoing development in France).

Home comfort, energy savings and indoor air quality: these are key preoccupations from our end-users on which Airium™ provides an unprecedented answer. Airium™ is a true revolution for both the construction and the insulation worlds.
