Arexpan

Since 2008, we are the sole manufacturer of expanded clay in Spain. Our Arexpan is the name of the expanded clay coming from the greenest mountains and best well-kept environment of Spain. Our clay has been manufactured in order to give the best performance under the most demanding requirements.

For those of you not fully familiarised with this term, it is just a natural clay high in iron that when calcined, produces a gasification that makes it expands and develops micro pores, giving it a high lightness plus other characteristics like an insulation both thermal and acoustic.
