CEMACON EVT 90 | Basaltic wool for thermal insulation, acoustic

Ask for more details

Thermal insulation

High energy efficiency, thanks to the very low thermal conductivity coefficient (λ=0.034 W/mK).

Acoustic Insulation

It provides improved acoustic comfort, as mineral wool has superior noise attenuation properties.

Fire resistant

It is a non-combustible product, which does not contribute to the development or maintenance of a possible fire. Reaction to fire: Class A1.

Vapor permeable

Mineral wool has a high vapor permeability, allowing the transfer of vapors to the outside of the building.

Hydrophobic

The cotton wool sheets are hydrophobized throughout their mass, thus water does not penetrate inside the sheets.

100% Natural

Being made from volcanic rock, a natural raw material, mineral wool is a natural product, which can be recycled up to 100%.
