Double-glazed windows are also more secure than windows with a single pane. They are more difficult to break and can be equipped with modern security locking systems. They can also be equipped with toughened or laminated glass, which makes them more secure.

It is essential to remove any broken glass as securely and swiftly as you can.

Gasket degrading is the primary reason for leaks and also moisture getting into buildings. Fortunately, the seals can be replaced without replacing the entire window.


Gaskets are often repaired by pressing them down and removing them. This is easier to do on uPVC frames than on timber or aluminium. If you're unable to remove seals by hand then you can use a builder’s knife to pry the seals apart until you are able to grasp it using your fingertips. After the seal is removed, you can use the new seal to ensure a tighter fit and maximum efficiency.

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

Once all of the beading has been removed after which you can take off the glass. To get the best thermal efficiency, the gap between two panes needs to be 12 millimeters. Argon gas should be used to fill the gap. A bigger gap can be used to reduce the sound levels however it can reduce the insulation capacity of windows.

After the frame has been cleaned it is recommended to spray it with window cleaner before placing the DGP. This prevents the tape from instantly sticking to the glass, and gives you a chance to position it in the right way. It's also worth wiping down the seals made of rubber with a soft cloth and warm soapy water in order to avoid any damage.

Re-seal the window

The misting of windows is usually an indication of a failing treatment of the glass in the factory. The factory will treat the window with a low-emissivity coating to reflect heat away and it may inject argon gas for extra insulation. When these treatments fail, moisture gets into the gap between the glass panes and it may cause condensation. This problem can be fixed by a professional who drills tiny holes through the glass panes, and then piping in a dehydrating solution to eliminate the moisture. The expert will then fill the gap with a new gas that is insulating and seal it, without letting any gas escape.
