Once all of the beading has been removed after which you can take off the window glass. The gap between the two panes should be between 12 and 12 millimeters, and it is important to fill this space with Argon gas to ensure optimal thermal performance. A larger gap can be used to lower the noise level, but it will lower the insulation performance of windows.

After the frame is cleaned it's an ideal idea to spray it with window cleaner before fitting the DGP. This stops the tape from securing to the glass, and gives you the chance to put it in the right way.

If these treatments fail, moisture could enter the gap between the glass panes and cause condensation. A professional can address this issue by drilling tiny holes into the glass panes and piping in a dehydrating agent to remove the moisture. The expert will then fill the gap with a new gas insulating the area and seal it, without the gas from escaping.
