According to one embodiment, an insulation blanket for insulating a structure includes a first facer layer and a second facer layer. A plurality of intermeshed non-woven glass fibers are disposed between the first and second facer layers and a fumed silica insulating powder is also disposed between the first and second facer layers. The fumed silica insulating powder has an average particle size of between about 2 and 20 nanometers. The insulation blanket includes at least one exposed edge having a cauterized face that forms a barrier on the exposed edge to encase the fumed silica insulating powder within the interior of the insulation blanket, which minimizes degradation of the insulating value due to loss or shedding of the fumed silica insulating powder through the exposed edge. The cauterized edge has a depth of cauterized material of between about 0.05 mm and 3 mm.
