URSA Mineral wool Pureone USF 31 IT

URSA PUREONE mineral wool products are completely free of formaldehyde and use natural thermosetting bonding resins. Ideal for thermal and acoustic insulation of buildings. URSA PUREONE's acoustic performance, such as dynamic rigidity, airflow resistance and sound absorption, has been carefully optimised to achieve maximum acoustic comfort in buildings. Furthermore, the low thermal conductivity values offer excellent thermal comfort. Preferred applications are pitched roofs, insulation in the soffit, non-inhabitable attics and perimeter walls. Excellent fire response.
