Scanning electron image (a) [13] and real image (b) (taken by authors) of glass fibers. Left image is a SEM picture of glass fiber insulation. The shape of the glass fibers is cylindrical which lead to small areas of contacts and thus small conductive heat transfer even if the material is compressed [13].
