Naturally ecological pumice, 100% natural

The result of volcanic eruptions, pumice is the PONCEBLOC raw material and it is merely screened to achieve the target particle size.
It undergoes no transformation or industrial processing (firing, expansion or other).

The air trapped in the non-intercommunicating cavities that make up its structure endow pumice with exceptional intrinsic qualities: thermal and acoustic insulation, lightness.

PONCEBLOC is produced locally and simply moulded and cold pressed (without any firing).
100% mineral, 100% recyclable. It is an inert product that produces no VOC.

Its outstandingly low impact on the environment has been confirmed by an EHDS, thus making PONCEBLOC the material with the best environmental offset.
