This can make a huge difference to your windows' insulation properties because it blocks heat from passing through the glass. By selecting an inert low-conductivity gas like argon or krypton to fill your windows, you will improve their insulation properties.

Double-glazed windows are also more secure than windows with a single pane. They are more resistant to breaking and can be fitted with modern security locking systems. They can be fitted with laminated or toughened glass to make them even more secure. Double glazed windows are more robust and less prone to sway in the wind or from vibrations from heavy traffic and are a good choice for older homes.

Insert the blade of the knife between the frame and the bead in the middle of the longest bead. This will give you maximum leverage to separate the frame from the bead.

After all the beading has been removed, you can then remove the glass. To get the best thermal performance, the distance between two panes should be 12mm.

The factory will put a low-emissivity coating on the window to reflect heat and could also inject argon for extra insulation. If these treatments fail, water can get into the space between the glass panes and cause condensation. A professional can fix this issue by drilling tiny holes into the glass panes, and then piping in a dehydrating agent to get rid of the moisture. They will then fill the hole with a fresh insulating gas and reseal the gap without letting the gas escape.
