EKOFIBER®
EKOFIBER®
EKOFIBER® is a loose, thermal insulation material made of cellulose fiber that creates a barrier to heat flow. It is characterized by high fire resistance and protects against fungi and mold growth. To achieve such parameters, the fiber is properly chemically impregnated.
EKOFIBER® is perfect for transferring moisture without accumulating it and therefore does not require the use of a vapor barrier foil. It is suitable for use throughout buildings, perfectly protecting it against fungus and preventing corrosion and the settlement of rodents and insects.
Application
EKOFIBER® is widely used as thermal insulation of various building structures, regardless of the construction materials used and the purpose, ranging from single-family houses and farm buildings, through industrial and sports facilities, to large-scale apartment blocks and sacred buildings.
Technical data
