Arexpan insulation is produced from clay. The calcination of this material generates gases that provoke its expansion and the formation of micro-pores that are thermally and acoustically insulating. The resulting expanded clay is lightweight (permitting savings in structural work), highly resistant to fire and extremely durable; in addition, it is free of toxic substances. It is supplied in different granulometries: coarse (spheres of 8-16 mm) and fine (spheres of 3-10 mm), to be used for roofs, levelling fill, floor substrates, slabs, to create slopes, lightweight concretes, etc. 0-5 mm ground Arexpan is also available, as well as 0-4 mm sand for lightweight concretes, lightweight insulating blocks, prefabricated panels, lightweight fireproof mortars, etc. Arexpan is supplied in sacks, big bags and in bulk for on-site mixing with water and cement. Arexcem is a ready-to-use product premixed with cement. Arexplantas is used to improve the soil substrate for plants. It helps aerate the soil, offers protection against frosts, conserves humidity, etc.
