Refilling Argon thermal pane windows
I have double pane thermal doors (sliding glass) I am going to be repairing this summer. Rot has started on the lower half and I'm thinking of repairing them (with pressure treated lumber) and then injecting argon gas in between the panes to keep the insulation value (after of course sealing all the edges with silicon). The argon is easily available from welding supplies stores or even on-line for wine preservation. The atomic mass of argon is 39.95 whereas the atomic mass of air is 28.97 meaning argon is heavier than air (of course factors such as humidity should affect this). So theoretically I should be able to drill two small holes (one to inject argon and one to release pressure) from the top of the repaired door and "recharge" the window after repair.
I know, just replace the sliding glass door. Well, I have thirteen of them. Not all are bad and if I do one, I will have to do them all or they won't match. A small fortune.
Does this sound feasible/workable?
