ECOMATERIALS

Ecological and sustainable thermal insulators
They have a great thermal insulation capacity. In other words, they are poor transmitters of heat or, in other words, their thermal conductivity is very low.
The Coefficient of Thermal Conductivity defined as ʎ = W / mK (Watts per meter and Kelvin degree), is the parameter that identifies the capacity of a material as a heat transmitter, qualifying it as an insulator (very low conductivity) or a conductor (conductivity high). In typical insulators, such as air or cork, this coefficient ranges between 0.02 and 0.05 W / m ∙ K. In contrast, metals such as iron or silver, which are good conductors of heat, have coefficients of thermal conductivity between 80 and 400 W / m.K.

CORK: Cork is a 100% natural material that comes from the bark of cork oaks, trees that grow in areas with a Mediterranean climate. Its production is sustainable since even during its extraction the generation of waste is low. The Cork Oak renews its bark every 9‐12 years, and this makes it possible to obtain cork without damaging the tree.
Its structure in the form of polyhedral cells, which are practically empty inside, gives it extraordinary waterproof and insulating properties, both thermal (conductivity of 0.041 W / m ∙ K) and acoustic.
As insulation it is marketed in agglomerated sheets made through pressure and heat without using any type of glue. It can also be found in the form of chips, granules or crushed to fill cavities and even projected on facades and roofs, floors and walls. Cork could have the disadvantage of its limited resistance to fire (Euroclass E). However, insulating panels are currently subjected to a fire retardant treatment that considerably increases their resistance to fire, making them ideal for sustainable construction.

HEMP: It has excellent acoustic and thermal insulation properties with a conductivity of only 0.041 W / m ∙ K. It is marketed in the form of blankets made with fiber. And, with the woody surplus that remains after separating the fiber, lightened mortars are made to make walls or bricks. kobe‐cz hemp fiber insulation (hemp) is highly versatile and can be used for thermal insulation for wall, roof and floor constructions. It can also be used as an acoustic board, insulation against step sound (sub floor insulation), airborne sound and as an insulation element that can be directly used in all construction parts.

Hemp isolation

SHEEP WOOL: It is a 100% ecological and renewable material since it comes from the necessary and regular shearing of the animal during its life. Its thermal conductivity, in a blanket, is very low: about 0.038 W / m ∙ K. Like cork sheets, wool sheets can be subjected to fire retardant treatments.
However, wool as an insulating material must be subjected to cleaning and protection treatments against attack by xylophages, and against moths with sodium borate.
Havelock Wool is healthy, high performance insulation made of 100% wool. The raw material is sustainably harvested in New Zealand and mechanically processed in the US without the use of any chemical binders. The inherent characteristics of the wool fiber provide an exceptional R Value, moisture management, passive indoor air filtration and superb sound absorption. Further Havelock Wool insulation is Class A rated for both fire hazard and flame spread.
The wool is a byproduct of the meat production industry and contains no synthetic mix or bonding agents making our products compostable at the end of extended useful life.
Sheep in New Zealand eat grass fed by rainfall and twice a year they need a haircut. This leads to 5kg or 10kg of wool per year that is available to be cleaned and turned into insulation.

COTTON FIBER: Felt based on light cotton fibers. The fibers are bonded with a thermosetting resin of the phenolic type normally fireproof. It is a material of plant origin that a fire‐retardant agent is added to it during the manufacture of the felt. Thermal conductivity: 0.033 λ

OSB (Orient Strand Board): boards are large pressed wood chip boards. Their resistance and versatility make them very suitable products for the structural elements of a building. But, in addition, due to their aesthetics, they can also be used as wall cladding or to make all kinds of furniture.
Natural origin. They are made from wood chips that are agglomerated thanks to the use of resins to later be subjected to pressure and temperature processes. Process that gives them density and resistance. These chips usually come from the natural environment, usually conifers such as pine and fir. Ecological insulation In addition to its great resistance, the OBS board is a great thermal and acoustic insulator. It is a very good option for covering multimedia rooms without the need to apply any other type of additional finish. It preserves the thermal insulation properties of wood and wood agglomerates.
For the production of OSB boards, no felling of trees is used. The raw material is obtained from thin logs from self sustaining forests. In addition, it is a 100% recyclable product, making it an optimal material for sustainable construction projects.
Its applications are very varied. From the structural elements of a home, through wall, floor or pavement coverings, to furniture and platforms, among many others.
