5 Motives Repairing Double Glazed Windows Is Actually A Great Thing Repairing Double Glazed Windows

When double-glazed windows "blow", the insulating gas argon escapes, causing them to lose their energy efficiency. The good thing is that blown double glazing is often repaired without needing to replace the windows.


The most typical sign of a damaged window seal is moisture or condensation between double-glazed windows. This can be easily repaired by a professional saving you the expense of a new window.

Remove the Sash

Double-glazed windows are an excellent option to improve the appearance and value of your home. They also boost the energy efficiency of your home by keeping cold out and the warmth in. Double-glazed windows can help you save money on heating bills in Minnesota's harsh winters.

The primary distinction between double and single windows is the gas that fills the space between panes of air or argon. This can make a huge difference to your windows' insulation capabilities because it blocks heat from transferring through the glass. Choosing an inert gas with low thermal conductivity like argon or krypton, helps to increase the insulating properties of your windows further.

Another benefit of double glazed windows is that they are much more secure than single paned windows. They are less resistant to breaking and can be fitted with modern security locking systems. They can be equipped with laminated or toughened glass to make them even more secure. Double-glazed windows are more durable and less prone than single-glazed ones to shake or rattle in the wind. They are a great choice for older homes.

Additionally, double-glazed windows can also be made using low-energy glass that reduces the UV rays entering your home. This can ensure that your carpets, paintings and furniture from discoloration. This is particularly helpful for windows that are exposed to direct sunlight for much of the day.

Another reason that homeowners decide to have their older sash windows retrofitted with double glazing is that they are a lot less expensive than installing new windows. The linings and cladding of your existing windows are still intact which makes the task less invasive.

In addition as an added benefit, the installation of double-glazed windows is a lot faster than taking out and replacing a complete window. This means that you will be able to benefit from energy efficiency, enhanced security and reduced glare and UV damage to your furniture for a much lower price.

Remove the Glass

Double-glazed windows differ from single pane windows because they have two glass panes, separated by an air layer and an air spacer. This provides insulation. This insulated unit (IGU), which is filled with gases such as argon or Krypton, can offer even more insulation. In time, these units can get damaged and stop functioning. perform properly. If this happens, it's important to remove the damaged glass as quickly and safely as is possible.

It can be difficult to replace double-glazed windows on your own. You will need specialised tools and expertise. This is why it is typically best left to a professional who will use the proper safety equipment and follow the correct procedure to avoid injuries.

To safeguard yourself when repairing your window, wear gloves that are protective and wear a mask or respirator. Make sure the area surrounding the window frame is free of debris and clean. Then, you need to put a thick piece of plastic over the frame that will be shaved by the deglazing tool in order to catch pieces of glass that have broken and make it easier to take them away.

In addition to replacing broken glass, it's also important to look for signs that your double glazed windows aren't working properly. A draughty window is among of the most frequent signs that your IGU is blowing and is no longer able to provide the proper insulation. It is also possible to determine the windows are cloudy or the presence of condensation between them.

Double glazing is not only an option to reduce energy costs but also to shield your furniture from heat and light. Furniture can deteriorate and break when exposed to sunlight for prolonged periods of time, but a double-glazed window will keep your furnishings out of direct sunlight, and also reduce the amount of heat that is brought into your home.

Apart from being a great method to cut down on energy costs, efficient double glazing can also boost the value of your property. If you're looking to sell your home in the near future, having double glazing installed is a smart investment that could attract potential buyers.

Remove the Gaskets

Double glazing is a popular choice to boost the efficiency of your home's energy use however, like all other things, it can be prone to wear and tear. Double glazed windows that show visible damage, have draughts or are susceptible to condensation should be repaired or replaced.

A crucial component of the window assembly is the gasket, a neoprene or butyl rubber seal that cushions the glass and offers weather protection. Gasket degradation is a leading reason for leaks and water getting into buildings. Fortunately, these seals can be replaced without replacing the whole window.

Gaskets are often repaired by pinching them and pulling them out. This is easier to do on uPVC frames than on aluminium or timber. If you're unable remove the seals by hand it's best to use a knife for construction to pry away the seal until you are able to grip it using your fingers. Once the seal has been removed and replaced, you can replace it with a new seal to ensure a snug fit and maximum effectiveness.

Once the seals have been replaced, the window beading needs to be removed. You can make use of a lead or putty knife to remove the window beading. Insert the blade between the frame and the bead at the middle of longest bead. This will give you maximum leverage to cut off the frame from the bead.

After all the beading has been removed, you can then remove the glass. The gap between the two panes must be about 12mm and it's important to fill this space with Argon gas for optimum thermal performance. A wider gap can be used to reduce noise levels however it can reduce the insulation performance of windows.

Once the frame is cleaned, it's recommended to spray the frame with window cleaner prior to installing the DGP. This stops the tape from securing to the glass, and gives you the chance to place it in the right way. To avoid any damage, it's worth wiping the rubber seals down with a soft cloth and warm soapy water.

Close the Window

It may be time to reseal your double-glazed windows if notice that they're fogged up or have moisture between them. This is a clear indicator that the inner seal has failed to keep the insulating gases in. It is not unusual to find the rubber seal that holds in the gases that are insulating to break down in time or because of improper installation.

A professional window specialist will reseal every gap by applying a fresh seal. The technician will fill the gaps with silicone caulk. This will keep cold air out and the warm air in during winter. This caulk will prevent insects from getting into your home and will also stop moisture from entering.

Re-sealing double-glazed windows is not a simple DIY project. But it is doable. It is a difficult and time-consuming job that requires special tools to take off the caulk that was used, clean the area, and then apply a new one. It is recommended to hire an experienced glazier to complete the work to avoid injury and to ensure that it is done properly.

There are window repairs in which double-glazed windows cannot be repaired and it will need to be replaced. This could include cracked or shattered glass, extensive damage to the frame, or serious decay. Consult a double-glazing expert to determine the best option in these situations.

The misting that occurs on the windows is a sign 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 the gas argon to provide insulation. If these treatments fail, moisture can be introduced into the gap between the panes of glass and cause condensation. A professional can solve this issue by drilling tiny holes in the glass panes, and then piping in a dehydrating agent to remove the moisture. They will then fill the gap with a fresh insulating gas and seal the gap, but without letting the gas escape.
