The primary distinction between single and double glazed windows is that the space between the glass panes is filled with air or an inert gas such as argon. This can make a significant difference in the insulation properties of your windows as they stop the transfer of heat through the glass. By choosing an inert, low-conductivity gas, such as argon, or krypton to fill your windows, you can improve their insulation properties.

Double-glazed windows are also more secure than single-paned windows. They are harder to break and are able to have modern security locking systems installed. They can be fitted with toughened or laminated glass to make them even safer. Double-glazed windows are more durable and less likely to rattle in the wind or due to the vibrations of heavy traffic and are a good option for older homes.

Take the Glass off

In contrast to single pane windows double-glazed windows feature two glass panes that are separated by a spacer and a layer of air that provides insulation. This insulation unit (IGU), which is filled with gases such as Krypton or argon, can offer even more insulation. As time passes these units may get damaged and stop functioning. perform properly. If this happens it's crucial to get rid of the broken glass as quickly and safely as is possible.

Replacing double glazed windows can be a daunting DIY job that requires specialised tools and techniques. This is why it's usually best left to a professional who can make use of the right safety equipment and follow the correct procedure to prevent injuries.

Make sure that the area around the window frame is free of debris and clean. In addition, you must place a thick sheet of plastic over the area that will be shaved by the deglazing tool to capture the pieces of glass that are broken and make it easier to remove them.

It is crucial to identify indications that double-glazed windows aren't working correctly. A window that is draughty is one of the most frequent signs that your IGU has blown and is no longer able to provide adequate insulation. You can also determine the windows are cloudy or if there is condensation between them.

Double glazing is not just an opportunity to save money on energy bills but also to shield your furniture from light and heat. Furniture can deteriorate or break if exposed to direct sunlight for a long period of time.

Gasket degrading is the primary cause of leaks, and also moisture entering buildings. Fortunately, these seals can be replaced without having to replace the whole window.

Gaskets are often repaired by pinching them and pulling them out. It is easier to repair uPVC frames than timber or aluminum. If you're unable to remove the seals by hand, it's a good idea to use a knife to remove the seal until you can hold it using your fingers. Once the seal is removed, you can put in a new seal for the best fit and efficiency.

After the seals have been replaced the window beading has to be removed. This can be done with a putty knife or a lead knife. Place the blade of the knife between the frame and bead in the middle of the longest bead. This will give you the most leverage to remove the bead from the frame.

After removing the beading, you can then remove the window glass. For optimum thermal performance, the distance between two panes needs to be 12mm. Argon gas should be used to fill the gap. A bigger gap could be used to reduce noise levels, but it will lower the insulation capacity of windows.


Once the frame has been cleaned it is an ideal idea to spray the frame with window cleaner prior to installing the DGP. This will stop the tape from adhering to the glass in a flash and give you time to position it correctly. To avoid any damage, it's worth wiping the rubber seals down with a soft cloth and warm soapy lukewarm water.

Re-seal the Window

If you notice that your double glazed windows are getting cloudy or you notice that there is water between the panes then it may be time to have them resealed. These types of problems are a clear indication that the inner seal isn't keeping the gas that is used to insulate. This is not unusual and the rubber that holds in the insulating gas can break down due to wear and tear or poor installation.

It is a good idea to consult a double glazing expert to determine what the best solution is in these circumstances.

The misting that occurs on the windows can be an indication that the treatment of the glass in the factory has failed. The factory will treat the window with a low emissivity coating to reflect heat away and it may inject an argon gas to provide additional insulation. If these treatments fail, moisture can enter the gap between the panes of glass and cause condensation. A professional can address this issue by drilling tiny holes in the glass panes, and then piping in a dehydrating agent to get rid of the moisture. The expert will then fill the gap with a new gas insulating the area and seal it, without letting any gas escape.
