    Hi, got some a rated argon filled with Swiss spacer units which we fitted and notified to council about 2 1/2 years ago, the glazed units I understand were made by sola glass, and 2 units have misted up! 2 1/2 years isn't really acceptable, is there any particular possible cause or just one of those things?

    Just want to make sure it wasn't an installation thing that could of caused it.
    But has been fine until now for 2 1/2 years.

    Thanks

    Could be a whole host of things

    1 - Manufacturing, solaglas are good but you never know

    2 - Installation; has silicone been used anywhere to seal up, silicone attacks the sealant used in sealing up units.

    Have the correct glass packers been used (if any at all), using too narrower packers means one pane may not be supported allowing it to slip over time normally helped with a bit of sun.

    Using no packers at all means the glass sits in water that weeps passed the gaskets, built in drainage systems usually take the water away but if any remains coupled with the glass being too low means the unit touches the water, if it does then death of the unit is inevitable, within months usually.

    Have bridge packers been used so as not to block the drainage system or stop it from working efficiently, again water touches the unit and its only a matter of time

    However bearing all the above in mind it is widely accepted within the glazing trade the DGU's are only expected to last 5 years now, yes its crap I know and yours haven't even reached that, I would imagine there was/is a fault with your install but get somewhere near 5 years and its to be expected

    What is the window made of?
    PVC, Wood etc?

    There are alot of old wood windows around that were adapted poorly to take double glazed units and they will never last long in these windows.

    Assuming they have the correct edge covering with the correct materials. Vented, Air gap all around, Drainage, Packed up at least 5mm and fitted with the recommended method then hopefully the factory will make you some new ones free of charge.
