Abstract

At least some embodiments of the present disclosure provide a roofing accessory that includes a radiofrequency radiation shielding non-woven fiber composite material. The radiofrequency shielding non-woven fiber composite material includes a first fiber type that includes a conductive material, where the radiofrequency shielding non-woven fiber composite material has a sufficient amount of the first fiber type so as to result, when the radiofrequency shielding non-woven fiber composite material is positioned on a roof structure, in the radiofrequency shielding non-woven fiber composite material allowing for shielding a predetermined percentage of electromagnetic radiation passing through the roof structure. The radiofrequency shielding non-woven fiber composite material includes a second fiber type that includes a non-conductive material. The first fiber type and the second fiber type are randomly dispersed within the radiofrequency shielding non-woven fiber composite.

First claim

What is claimed is:

1. A roofing shingle, comprising:
a layer, comprising:
a binder;
a first non-woven fiber type dispersed in the binder;
wherein the first non-woven fiber type comprises a conductive material;
wherein the roofing shingle has a sufficient amount of the first non-woven fiber type so as to result, when the roofing shingle is positioned on a roof deck, in the roofing shingle allowing for shielding a predetermined percentage of electromagnetic radiation passing through the roof deck; and

a second non-woven fiber type dispersed in the binder;
wherein the second non-woven fiber type comprises a non-conductive material; and
wherein the second non-woven fiber type is configured to provide structural reinforcement;
wherein the first non-woven fiber type and the second non-woven fiber type are mixed so as to be randomly dispersed within the binder of the layer.

2. The roofing shingle of claim 1 , wherein the conductive material of the first non-woven fiber type comprises a metal.

3. The roofing shingle of claim 1 , wherein the conductive material of the first non-woven fiber type comprises copper.

4. The roofing shingle of claim 1 , wherein the conductive material of the first non-woven fiber type comprises aluminum.

5. The roofing shingle of claim 1 , wherein the non-conductive material of the second non-woven fiber type comprises glass fiber.

6. The roofing shingle of claim 1 , wherein the predetermined percentage of electromagnetic radiation is at least 50%.

7. The roofing shingle of claim 1 , wherein the predetermined percentage of electromagnetic radiation is at least 75%.

8. The roofing shingle of claim 1 , wherein the predetermined percentage of electromagnetic radiation is at least 90%.

9. The roofing shingle of claim 1 , wherein individual fibers of the second non-woven fiber type have a length of 3 mm to 140 mm.

10. The roofing shingle of claim 1 , wherein individual fibers of the second non-woven fiber type have a diameter of 5 micrometers to 25 micrometers.

11. A system, comprising:
a roof structure;
a first membrane installed on the roof structure,
wherein the first membrane comprises:
a layer, comprising:
a binder;
a first non-woven fiber type dispersed in the binder;
 wherein the first non-woven fiber type comprises a conductive material;
 wherein the first membrane has a sufficient amount of the first non-woven fiber type so as to result in the first membrane shielding a predetermined percentage of electromagnetic radiation from passing through the roof structure; and
a second non-woven fiber type dispersed in the binder;
 wherein the second non-woven fiber type comprises a non-conductive material; and
 wherein the second non-woven fiber type is configured to provide structural reinforcement;
 wherein the first non-woven fiber type and the second non-woven fiber type are mixed so as to be randomly dispersed within the binder of the layer; and

a second membrane installed on the roof structure,
wherein the first membrane is between the roof structure and the second membrane.

12. The system of claim 11 , wherein the conductive material of the first non-woven fiber type comprises a metal.

13. The system of claim 11 , wherein the conductive material of the first non-woven fiber type comprises at least one of copper or aluminum.

14. The system of claim 11 , wherein the non-conductive material of the second non-woven fiber type comprises glass fiber.

15. The system of claim 11 , wherein the predetermined percentage of electromagnetic radiation is at least 50%.

16. The system of claim 11 , wherein the predetermined percentage of electromagnetic radiation is at least 75%.

17. The system of claim 11 , wherein individual fibers of the second non-woven fiber type have a length of 3 mm to 140 mm.

18. The system of claim 11 , wherein individual fibers of the second non-woven fiber type have a diameter of 5 micrometers to 25 micrometers.

19. The system of claim 11 , wherein the roof structure is the roof structure of a commercial structure or industrial structure.

20. The system of claim 11 , wherein the roof structure comprises a board.
