Cork Natural insulating felt and panel for sustainable building
Thermal acoustic hygrometric insulation panel, 100% compressed blond raw cork, with a high density and vegetable based binders, and containing a certain amount of cork recycled as a secondary raw material. Industrial production from locally grown raw materials and with local partners. Renewable raw material. No toasting. No tree cutting.. The world's first and only raw cork panel to be ICEA (Ethical and Environmental Certification Institute) certified. Recyclable and reusable.
APPLICATIONS Suitable for roof, attic and floor insulation in low-energy buildings. It is installed over a dedicated air barrier on dividing and perimeter walls, on roofs, in internal sheathing, on subfloors of terraces and dwelling floors, and in stairwells.
Excellent thermal, hygrometric and acoustic insulation. Perfect for maximising energy efficiency, for acoustic correction, and for protection from stamping or more distant sounds, like airplane noise. It ensures a healthy environment and prevents condensation.
