1. A composite comprising a stack of layers, the stack comprising:
a porous polyimide aerogel layer having a first surface and an opposing second surface;
a first support layer having a first surface and an opposing second surface, wherein the first support layer comprises a polyurethane film;
a second support layer having a first surface and an opposing second surface, wherein the second support layer comprises polyethylene, and wherein the first surface of the first support layer is attached to the second surface of the second support layer,
wherein an interface is formed between a portion of the first surface of the porous aerogel layer and a portion of the second surface of the first support layer such that the first surface of the aerogel layer and the second surface of the first support layer are in direct contact with one another, and the first support layer at least partially permeating into pores of the porous polyimide aerogel layer,
wherein a majority of the volume of the aerogel layer does not include the first and second support layers, and
wherein the composite stack has a thickness of 3 mils to 16 mils; and
wherein the first support has a thickness of 0.5 to 2 mils.
