    Argon Gas

    I have a HH double bubble pad and it got me thinking about the air inside the bubbles. I doubt it already has Argon gas inside the bubbles though I wonder how much more expensive it would be to inject Argon during manufacture. Not alot of space inside the bubble but I am sure Argon could increase the insulation factor enough to make it worth *our* while. Any thoughts or insite? I know there is a company that makes *rechargeable* mats for this kind of thing but who wants to pay the prices they are asking for their proprietary gas rechargers; static argon bubbles would be more cost effective.

    BTW I am new here, Hello everyone, and thanks for the invaluable information and effort you have contributed. In a world filled with turmoil it is wonderful to witness the best in humanity on this site. Among the most moving is witnessing people step up to help a fellow who had to endeavor the worst in humanity. Awesome!!!

    Welcome to HF from Mass. Interesting idea about the argon.

    As a drysuit diver, there is all kinds of debate about the benefits of using argon as an inflation gas for diving drysuit use.

    Most folks I dive with feel the benefits are either marginal or imperceptible.

    I guess it would be worth a try, but I'd be pleasantly surprised if there were any significant benefit.

    Let us know how it turns out.

    True enough, but saying Argon would not be practical for our application because it is not efficient for dry suit applications in deep water, is like saying CO2 wouldn't make a good fire extinguisher because it would not stop the flow of lava. I'm being silly to make a point, awake for over 24 hours now, but they do use Argon to fill double pane windows; which I think would be closer to our application. So it might have some benefit for us.

    Very interesting idea, and I'll be following this forum to see where it goes, since I know zilch on the subject. Something that does come to mind is, instead of Argon, how about Helium? It could be the first negative weight pack item ever!! (Sounds silly, but for those of you that could actually run through the feasibility of this idea in terms of materials engineering, humor me. Can it be done? )

    Is that for some superior insulating value, or simply to have a dry gas to prevent condensation between the panes?

    Edit...nevermind...google took care of the question. Argon has less convective loss than air or nitrogen.

    The difference in thermal conductivity between Argon and plain old air is only 0.008. I don't think that you'd be able to pack enough gas into a pad to make it worth the effort and expense. The boost you'd get would be tiny and as DiscoveryDiver said, this is a discussion that has been going on for years by folks who are at least as passionate about their gear as we are on this board. Even the advocates for dry suit use admit that their perceived experiences have resulted in modest gains at best.

    Now then, to have a sealed gear-chest filled with Argon would eliminate any concerns about mold while in storage for those folks in humid climates.
    Trust nobody!

    It's one thing to add the expense of argon gas fill to a thermal window for a house and another to do it to bubble wrap. The small improvement in a window adds up over time since it's at work 24/7 for years on end.

    Here's some info. http://www.ehow.com/about_4794088_vs...nsulation.html

    Also, argon is five times heavier than air so the gram weenies won't be happy!

    I like Stefprez' helium idea. Not sure what the insulation factor is compared to air.

    Helium insulates WAY less than air. But, it is lighter!
