- 1 - HOE 88/F 286 Abstract: Support web for roof foundation webs A support web is described for roof foundation webs which comprises a spunbonded web of polyester filaments. The spunbonded web has a basis weight of 50 to 100 g/m2 and a filament denier of 1 to 8 dtex. It has been thermo- mechanically preconsolidated by means of a smooth calen- der and end-consolidated by means of a binder. This produces a high tear propagation resistance and nail removal resistance and good dimensional stability at high temperatures. The spunbonded web is therefore particular- ly suitable for use as a support web for bituminized roof foundation webs.
