A layered thermal insulation system generally conformable to three-dimensioned surfaces of heat-producing elements in need of insulation is described. The system comprises: i) an inner high temperature resistant insulation layer; ii) an outer high temperature resistant insulation layer adjacent the inner high temperature resistant insulation layer; and, iii) a first reflection layer and a second reflection layer. Each of said reflection layers is formed of a material selected from a group consisting of metal foils and are provided with a plurality of dimples and/or protrusions. The first reflection layer is adjacent the inner high temperature insulation layer such that, in use, an opposing surface thereof is in close proximity to said surfaces of said element to be insulated. The second reflection layer is adjacent to the outer high temperature insulation layer such that, in use, an opposing surface thereof comprises an exposed surface having a lower temperature than said surfaces of said element.

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.

Provided herein are nanofibers and processes of preparing nanofibers. In some instances, the nanofibers are metal and/or ceramic nanofibers. In some embodiments, the nanofibers are high quality, high performance nanofibers, highly coherent nanofibers, highly continuous nanofibers, or the like. In some embodiments, the nanofibers have increased coherence, increased length, few voids and/or defects, and/or other advantageous characteristics. In some instances, the nanofibers are produced by electrospinning a fluid stock having a high loading of nanofiber precursor in the fluid stock. In some instances, the fluid stock comprises well mixed and/or uniformly distributed precursor in the fluid stock. In some instances, the fluid stock is converted into a nanofiber comprising few voids, few defects, long or tunable length, and the like.
