Definitions
- the present invention refers to a composite support with fire resistance property for bituminous roofing sheaths.
- non- woven sheaths in chemical textile material, for instance polyester, is known in order to provide a support for bituminous roofing sheaths. It is also well known to provide such supports by means of two non- woven layers comprising reinforcing filaments, in particular glass filaments as described in Italian Patent 1237149.
- EP 667427 teaches an association of two non-woven layers with interposition of a glass film, which has the task to create a barrier to the fire and to the leaking of bitumen in case a fire develops over the roof.
- scope of the present invention is to provide a composite support with fire resistance property for bituminous roofing sheaths, that is capable to obviate to the disadvantages of the known technique.
- a composite support for bituminous sheaths comprising a first and a second layer of non- woven synthetic material mat and a glass film interposed between said layers, characterised in that it additionally comprises between said first and second mat layers a plurality of longitudinally oriented reinforcing glass filaments.
- the glass filaments guarantee, both in the stage of production of the support and in the stage of impregnation with bitumen, the non- lengthening of the non-woven layers with respect to the glass film, with consequent greater resistance to the formation of fissures or cracks of the latter and equally consequent improvement of its fire resistance property.
- Figure 1 shows schematically an embodiment of the production process of the composite support according to the present invention
- Figure 2 shows the composite support according to the present invention in transversal section.
- a first layer 1 of non-woven fabric, in particular polyester polymer, is fed by a first extrusion head A onto a conveyor belt 3.
- reinforcing glass filaments 4 are unwound from coils 5 thanks to appropriate traction means (not shown in figure).
- the glass film 6 in turn is unwound from a coil 8.
- a second layer 7 of non- woven fabric, of the same material as before, is placed that is fed by a second extrusion head B.
- a composite support 9 is thus obtained, shown in section in Figure 2, in which the glass film 6 is located inside the two non- woven layers 1 and 7 that are in turn reinforced in longitudinal sense by the filaments of reinforcing glass 4.
- the presence of the reinforcing glass filaments 4 guarantees, both in the stage of production and in the stage of impregnation with bitumen of the composite support, the non-lengthening of the layers 1 and 7, thus preventing the fissuring or cracking in the glass film 6.
- the invention can be machined in the stage of the impregnation with bitumen even at high temperatures, since the reinforcing glass filaments 4 prevent the stress of the chemical material that makes up the layers 1 and 7.
