Repairing Double Glazed Windows

This can make a significant difference to the insulation properties of your windows by preventing heat from passing through the glass. Selecting an inert gas that has a low thermal conductivity, like argon or krypton which can help increase your window's insulating properties even further.

Another benefit of having double glazed windows is that they are more secure than single paned windows. They are less secure and resistant to breaking. They can also be equipped with modern security locking systems. They can also be fitted with toughened or laminated glass, which makes them more secure.

Gaskets are often repaired by making them tight and removing them. This is much easier on uPVC frames than on aluminum or timber. If you are unable remove seals manually, you can use a builder’s knife to pry the seals apart until you can grasp it with your fingers. After the seal is removed, you can use an alternative seal for a tighter fit and maximum effectiveness.

After the seals have been replaced, the window beading needs to be removed. This can be done using a putty knife or a lead knife. Insert the blade between the frame and the bead in the middle of the longest bead. This will give you the maximum leverage to remove the bead from the frame.

After all of the beading is gone after which you can take off the glass. The gap between the two panes should be between 12 and 12 millimeters, and it's important to fill it with Argon gas for optimum thermal performance.

The misty windows are often a sign of a failed treatment of the glass at the factory. The factory will treat the window with a low emissivity coating to reflect heat away. Additionally, it may pump in an argon gas to provide additional insulation. If these treatments fail, moisture can get into the space between the panes of glass and cause condensation. This issue can be solved by a professional who drills tiny holes through the glass panes, then piping into a dehydrating solution to remove the moisture. The expert will then fill the gap with gas insulating the area and seal it, without the gas from escaping.
