Finishes Siena
The aggregates — rice husk and hemp hurds — are the core elements of this finish. The rough, unstructured appearance of the surface conveys a typically rural, extremely natural look.
Why choose Terrae-Calce Siena
Breathability – VOC
The hygroscopic properties of lime (i.e. it absorbs water molecules from the surrounding environment) make it possible to moderate humidity levels, counteract the formation of mould, bacteria and fungi, and improve air quality, thus favouring the reduction of asthma and allergies.
They are highly breathable and therefore favour the natural passage of water vapour in the walls, limiting detachments due to blistering in humid areas.
Terrae-Calce products are VOC free.
Climate impact
To be produced, lime is fired at a lower temperature than many other solutions. This means that it has a reduced impact on the environment as, by being produced at a lower temperature, uses less energy.
Also, it uniquely reabsorbs part of the carbon dioxide (Co2) emitted during combustion thanks to the “Carbonation” process, while it polymerises in the installation (natural carbon sink), thus reducing the environmental impact.
(EPD in process).
Sustainability
AVAILABILITY
The raw material for the production of lime is limestone, a sedimentary rock rich in calcium carbonate (CaCO3); marble or other minerals can also be used. As these raw materials are widely present, their use does not contribute to the reduction of resources.
WASTE RECOVERY
The aggregates are all products of waste recovery: rice husk and hemp hurds.
