Abstract:
A nonwoven which comprises fibers or filaments consolidated with a binder and which is suitable for use as a carrier web in roofing sheets which are resistant to jump fire and radiant heat is obtained by applying, together with the binder, solid particles which are resistant to heat and fire and whose spatial extension in at least one dimension is large compared with the effective hole size of the web layer. This size ratio ensures that the solid particles form a layer on the web which becomes firmly bonded to the fiber or filament web.
