Base felt for roofing underfelts |
摘要 |
<p>The support web consists of a spunbonded material made of polyester filaments. The spunbonded material has an area weight of 50 to 100 g/m<2> with an individual filament count of 1 to 8 dtex and is fastened by a fusible binder. By means of this, a high tear propagation resistance and nail pull-out resistance and also a good dimensional stability results at high temperatures. The spunbonded material is therefore particularly suitable as a support web for bitumenised roof truss webs.</p> |
