Eco-Black expanded cork
The Eco-Black chipboard is the best for thermal insulation. It also acts as an acoustic insulation by absorption.
ECO-BLACK THERMO-ACOUSTIC INSULATING CORK. PURE AGLOMERATE WITHOUT ADHESIVES. ECOLOGICAL. DENSITY 110/115 Kg / M.3
It is manufactured in plates of 1, - x 0.50, - m.
On request it can be manufactured in 915 x 610 mm sheets.
In standard thicknesses of 20, - / 30, - / 40, - / 50, - / 60, - / 80, - / 100, - mm
On request, for special orders it can be manufactured up to 300, -mm thick. It can also be manufactured in 120 mm and 150 mm.
It is a product composed of virgin forest cork that is crushed into grains. it agglomerates in block and later it is cut in plates. It has a special manufacturing method by pressing it in a closed autoclave, injecting water vapor at high pressure and temperature and the suberine which acts as a binder is melted, and at the same time its composition cells expand. The melted suberine is what causes its peculiar smell of toasting, which over time is losing.
Orientatively for a very good isolation:
In perimeter walls it is advisable to use a minimum thickness of 50, -mm. And for covers from 80 to 100, -mm. Although the exact final calculation corresponds to the project technician.
For thicknesses greater than 50, -mm it is advisable to install two or three thicknesses in several layers, placed to break together to avoid thermal leakage, thereby increasing the insulating efficiency. Which does not represent any cost of the material to be installed, since its price is proportional to the thickness. USE: - Thermal insulation. Acoustic conditioning. Impact sound reducer. Expansion joints Insulation for moisture. Sloping and flat roofs. Isolation partitions. Exterior walls. -Applications: - Cold rooms. Public Buildings. Households. Factories Farms.
For rehabilitation of existing constructions, in which the insulation inside must be improved, it can be fixed directly to walls and ceilings with all mortars and glues available in the market (including plaster and plasterboard paste), and if you want It can be plastered directly with plaster or mortar.
When installed outside the buildings:
This material is served in complete packages of 300, - mm high. And the m.2 that contain each package are:

Pure expanded cork agglomerate.
Invulnerable to insects and microorganisms. Eco-Black expanded cork has an aqueous moisture content of less than 8%. This low water content makes the proliferation of microorganisms impossible. The suberin distillation process neutralizes the plant sap and is indigestible by rodents or insects. These particularities give it unlimited durability. Unlike wood and other organic or vegetable insulators, this expanded cork never rots or destroys.
Maximum humidity level: 8% - EN 1215. Waterproof and non-hygroscopic. It maintains intact qualities even in environments with high ambient humidity.
It allows walls and roofs to breathe.
