LafargeHolcim subsidiary Lafarge France has relaunched its Airium mineral foam, a concrete block additive, for use in roof insulation. Airium is an insulating technology that improves the energy efficiency of buildings. It can be used in block-filling, roof terraces, attics, sub-screeds and as cavity wall insulation. It is made from a cement-based slurry, aqueous foam and predominantly comprises enclosed and well-distributed air bubbles. It is the first mineral foam to offer a top-tier insulating performance, for an ideal thermal comfort, be it for cold temperatures or heat waves.
