Selecting an inert gas with low thermal conductivity such as argon or Krypton will help improve your window's insulating properties even further.

Double-glazed windows are also more secure than windows with a single pane. They are less resistant to breaking and can be equipped with modern security locking systems. They can be equipped with toughened or laminated glass to make them even more secure.

After all the beading has been removed, you can then remove the window glass. The gap between the two panes should be about 12mm and it's important to fill it with Argon gas for optimum thermal performance. A larger gap can be used to lower the sound levels however it can reduce the insulating performance of windows.

It's a great idea to spray the window cleaner onto the frame after it has been cleaned. This will allow the DGP stick better.

They could also inject argon for extra insulation. If these treatments fail, moisture could be introduced into the gap between the glass panes and cause condensation. This issue can be solved by a professional by drilling tiny holes through the glass panes, and then pipe in a dehydrating solution that will eliminate the moisture. The expert will then fill the gap with insulating gas and seal it up without let any gas escape.
