Gallery: Space-age Aerogel Insulation Now Cheaper and Available in Shee...


Insulation may not be sexy, but it is important. Over the past years we’ve seen leaps and bounds towards creating cheaper, thinner, more breathable materials with higher R-values. There still isn’t “one” insulation out there that has all the best characteristics, but Aerogel is one of the top contenders. This space-age material has the lowest bulk density of any known porous solid as well as some incredible insulating qualities, and recently two companies rolled out Aerogel sheets that make installations a breeze.

    What will be its TC at 45degree C, thermal resistance ? Can it be used in brick walls layer.

    @jeanmarc and @Arthur L Belge – there are already many companies making aerogel / nanogel insulated windows. Kalwall is one such company, Solera is another:

    I’ve made a Nanogel window before – Nanogel has no structural stability, so it needs to be sandwiched between plates of glass or plastic. Lots of companies are already making these sorts of products, as is stated in the article above (in fact that is the whole point of the article), but these products are generally pretty expensive.

    Arthur L. Belge >> Of course they’re working on it, the problem is that aerogel is currently too structurally weak to make a window out of it. Even small vibrations (like from trucks passing by) are enough to break it. But they’re like one or two steps away from it, I’m optimistic.

    Replacing old storm double windows is expensive. Eventually the gas between the window panes leaks out. Why not pump in aero gel. With an R-10.3 per inch R-value your windows could be better insulated than your walls. The aero gel would be invisible to the eye at that thickness. Why isn’t anyone doing this?

    i like know more about aerogel. please if you can send me more information about this kind of silica type. can i invest on one of your project?

    So….What IS the going price for this insulation per board ft? I often use open cell foam in my remodels at a rate of about $1 bd ft.
    I am often up against trying to get the best R value in limited space in my remodels. Foam gives me about R-7 /inch. Even if the areogel cost more per R there are cases where it can save money.

    […] close when the home detects hot or incremental weather, but still let natural light in through the aerogel translucent wall panels. The solar array on the roof adjusts its pitch to maximize its solar […]

    Does anyone know if there are any European firms that offer these products?

    Has it been used in clothing, cars, or camping equipment?

    Hmmm most importantly will it be cheaper than conventional insulation?

    I’d love to see this stuff come down in price so that it could be used to insulate homes. Think of the cost savings for heating and cooling.

    this is awesome. i’m ordering some for fun….
