More Information
Summary:A laminate which, when used as a carrier web for roofing and sealing sheets, shows good flammability properties combined with improved mechanical properties and which comprises a layer of synthetic fibers and a layer of mineral fibers is obtained by needling two preconsolidated fiber webs, of which one comprises synthetic fibers and the other mineral fibers. The needling produces a strong positive join of the two webs, as a result of which the tendency for the two layers to delaminate under extreme thermomechanical conditions is avoided.
