CalceCanapa, high quality insulation
From the union of lime and hemp, a new line of products for green building is born. It’s called «CalceCanapa®».
CalceCanapa® is an innovate and environmentally friendly material, that makes buildings more energy-efficient, healthier and more comfortable. CalceCanapa® is more than the simple sum of two materials, in fact is a new biocomposite in which the lime gains the insulating properties and the lightness of geomineralized hemp. CalceCanapa® offers a full set of products and solutions for the construction: thermal-plasters, blocks, interspaces, external insulations, roofs, foundations, finishing and pastel color washable paints.
Lime and hemp together make insulation durable and efficient for every environment, always with a special care for ecology, energy saving and living comfort.
THERMAL CONDUCTIVITY BETWEEN 0.050 E 0.095 W/MK
Thermal conductivity is the predisposition of a material to conduct heat. If a material has got a low Lambda value this means that it is a good insulator. Lower energy consumption means saving money and reducing the emission of pollution in the atmosphere. The thermal inertia is the ability of a material to preserve heat energy and to release it as time goes by. Hemp is characterized by an elevated specific heat, that’s why it creates a lot of benefits in terms of well-being living such as low cooling costs during the warm months.
WALLS CAN BREATH
Calcecanapa® combines permeability to the vapor of the lime and also to the hygroscopy of hemp. Hygroscopicity is the capacity of the hemp to absorb high amounts of water vapor. The walls of a building made of Calcecanapa® can absorb moisture and release it easily. This feature prevents the deterioration of the materials and facilitates the reduction of the total humidity level inside the building.
CALCECANAPA® IS CARBONEGATIVE
During its growth the hemp absorbs carbon-dioxide (CO2) from the atmosphere: a tonne of dry hemp captures about 325kg of CO2. Calcecanapa® Termointonaco is able to catch 110kg of CO2 per m3 which become 165 per m3 when Calcecanapa® Cappotto is setted up. Building with Calcecanapa® is an efficient way to contrast the global warming.
ENVIRONMENTAL SUSTAINABILITY WITH AN HIGH DECORATIVE EFFECT
Each different grain size and texture of the biocomposite can be left in view or colored with natural mineral pigments such as natural earths, ochers, etc. The high flexibility and the low hygrometric retreat minimise fissures and cracks, making the final result without the typical imperfections of the high thickness coatings. Moreover by using Calcecanapa® Tinteggio e Intonachino the aesthetic value of the internal and the external surfaces grows even more, thanks to the birefringence of the calcite.
NATURE IS 100% RECYCLABLE
At the end of its life, is sufficient a crushing process to reuse Calcecanapa® again as secondary raw material. It can be even used in new construction sites without the need treatmening it. As they are totally and easily recyclable, Termointonaco, Biocappotto, Finitura and all the other products of Calcecanapa® don’t need to be separated. In fact they belong to the same type of material..
SILENCE AND AIR QUALITY, FINALLY TOGETHER
The need to isolate rooms from external noises is important. However by doing it, there is the risk to lock ourselves in watertight and unhealthy containers. Thanks to the open structure created by Calcecanapa®, the acoustic wave absorption performance reaches 90% between 500 and 2000 Hz, with the result that unwanted resonances are almost total eliminated. Using Calcecanapa®, both sound absorption and breathability coexist in perfect harmony.
AIRTIGHT AND EVER USEFUL
Hemp is a pure, resistant and unalterable biological material. The use of lime determines the alkalinity of the biocomposite. Furthermore it contributes to preserve the walls and protects them from any form of infestation.
Plumbers have always used hemp to prevent water leaks in the joints of the tubes, while the ancient Egyptians used to wrap the mummies in hemp sheets to not make them attack by insects and rodents. That’s why they have been well preserved for thousands of years.
THERE ARE WINNERS WHO CAN PASS THE TEST OF TIME
In over thirty years of experience in using hemp and lime as building material and thermal insulation, we have never had problems with durability! The lifetime of Calcecanapa® is practically unlimited, as the lime mineralizes hemp making it unassailable by bacteria, molds, insects, rodents.
