EKOFIBER PLUS 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 PLUS 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.


EKOFIBER PLUS 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.
