EKOFIBER® is a loose thermal insulation material made from cellulose fiber that forms a barrier for the flow of heat. It features high flame resistance and secures surfaces against fungi and mould. In order to achieve such parameters, the fiber undergoes proper chemical impregnation.
EKOFIBER® is perfect for transferring moisture without storing it inside and, as a result, it does not require application of vapor barrier foil. It may be applied on the whole area of the building, perfectly securing it against development of fungi, preventing its corrosion, and protecting it from rodents and insects.
Form of loose granulate installed by injection blow method without technological loss (100% usage of material).
Applied installation densities:
– slab roofs, non-habitable attics – 27÷29 kg/m3,
– roof slopes – 40÷45 kg/m3,
– walls – 50÷55 kg/m3.
Thermal conductivity coefficient λ = 0,041 W/mK.
“Breathing” – it is not required to use vapor barrier in partitions insulated with Ekofiber.
Resistance to fungi and moulds.
Protection of wooden constructions against biodegradation and of steel constructions against corrosion.
Classification of reaction to fire C (PN-EN 13501-01)
Flame retardant – does not spread fire.
Hostile for insects and rodents.
High capacity of acoustic insulation.
|Frequency [Hz]||Reverberated sound absorption coefficient|
