Abstract

Laminates, which are composed of a preconsolidated synthetic fiber web and a preconsolidated mineral fiber web, which are bonded to each other by needling, are improved in respect of their dimensional stability, in particular in the transverse direction, when the preconsolidated mineral fiber wet contains reinforcing yarns of a mineral material and extending in the longitudinal direction. They are preferably used as carrier web for roofing and sealing webs.
