  1. You should know what you are talking about before you write as an expert. The argon in the window is not : “potentially dangerous” .. There is already 1.2% argon in the air – the amount a window might release is insignificant.

    “The downside of argon inert nature is that it doesn’t move. ” BS – argon moves just like any other gas the air is made of.

    “the implosion of the gas” The gas does not implode – the glass might – but for quite different reasons. If the windows were under filled you might see such breakage (very rare) – but that is a production defect.

    I find this article misleading, as breakage of south facing windows containing argon gas is commonplace. My landlady has lost four windows in a decade.

    It seems all that is needed is localised heat buildup due to a foreign object resting against window (a bag, a piece of clothing, a box) on a sunny day. The resulting, intense stresses in the glass have no means of escape, as eventually the glass shatters.

    Where such windows go right to the floor (south-facing patio or balcony), and especially where a succession of renters occupy the rooms (who tend to forget the dangers to the windows), several windows can be independently damaged within a relatively short time.

    Tempered (security) glass can be used on the inside, but these take far longer to manufacture – and cost correspondingly more.
