What I want to know is if it will be cheaper as right now even a small sample of areogel costs a small fortune. Its supposed to be one of the very best insulation materials but its
...cost prohibitive to insulate your house with it.
It should be less expensive than silica aerogel (which is made of quartz, and requires elaborate drying in an autoclave-like pressure cooker). That's because freeze-drying is a cheap way to remove liquid from the voids (and you NEED LOTS OF VOIDS).
It's unclear, however, if the mean-free-path for vapor movement is as small as a 'conventional' silica aerogel (the sample looks opaque, so probably the voids/walls are larger than wavelength of light). Silica aerogels for insulation are glass-clear (but slightly smoky) because the structure is nanometer-scale. It's unclear what cellulose does to 'improve' the product, and unclear that the product is durable.
It's called 'biodegradable' but does that mean fungus will nibble it to nothing inside a year? Even a slow-moving variant on wood rot could quickly destroy a nanostructure. It's shown as flexible, which would be good (part of the cost of insulating a house with aerogel, is that you have to size all the house stud spacings to exactly the dimensions of factory-cut aerogel panels).
