Why Everyone Is Talking About Repairing Double Glazed Windows Today
Repairing Double Glazed Windows

When double-glazed windows "blow", the insulating gas argon escapes, which causes them to decrease their energy efficiency. The good part is that blown double glazing is often repaired without the need to replace your windows completely.

Condensation or moisture in between your double-glazed windows is the most common sign that the seals on your windows have failed. This can be repaired by a professional saving you the cost of a replacement window.

Take off the Sash

Double-glazed windows can add value and style to your home. They also boost your home's energy efficiency and keep the cold out and the heat in. With Minnesota's harsh winters, having double-glazed windows will help you save on heating costs.

The primary distinction between double and single glazed windows is the gas that fills the space between panes of argon or air. This is a significant improvement to the insulation properties of your windows because they prevent the transfer of heat through the glass. By choosing an inert, low-conductivity gas like Krypton or argon to fill your windows, you will improve their insulation properties.

Double-glazed windows are also more secure than single-paned windows. They are more difficult to break and can be fitted with modern security locking systems installed. They can also be equipped with toughened or laminated glass, making them even more secure. Double-glazed windows are more sturdy and less likely than single-glazed windows to shake or vibrate in the wind. They are a good choice for older homes.

Double-glazed windows are also constructed of low-energy glass which helps reduce the UV rays that enter your home. This can help ensure that your carpets, paintings and furnishings from fading. This is particularly important for windows that are exposed to direct sun for most of the time.

Take the Glass off

Double-glazed windows differ from single pane windows as they feature two glass panes separated by an air layer and a spacer. This provides insulation. The insulated glass unit (IGU) can be filled with gases such as argon or krypton for even better insulation. These units can become damaged as time passes and stop functioning correctly. If this happens it is crucial to take away the broken glass as fast and safely as you can.

It can be difficult to replace double-glazed windows on your own. You will need specialised tools and expertise. It is recommended to leave this task to a professional who will make use of the appropriate safety equipment and follow the right procedure to avoid injuries.

Wear a respirator or gloves and mask to safeguard yourself when working on the window. Make sure the area around the window frame is free of any debris and clean. You should also place a thick piece of plastic over the area where the deglazing tool will score to catch any broken pieces of glass and make them easier to remove.

It's important to check for indications that double-glazed windows aren't working correctly. A draughty window is one of the most frequently observed signs that your IGU has burst and isn't providing adequate insulation. You can also notice if the windows are cloudy or there is condensation between them.

Double glazing isn't just an option to save money on energy bills but also protects furniture from heat and light. Furniture may deteriorate or break if it is exposed to intense sunlight for a long time. Double-glazed windows keep your furniture from the sun and reduces the amount of heat entering your home.

The gasket is a crucial component of the window assembly. It is a neoprene seal that cushions and shields the window from the elements. Deterioration of the gaskets is a common reason for leaks and water infiltration into buildings. Fortunately, the seals can be replaced without having to replace the entire window.

The gaskets are often able to be repaired by pinching them and pulling them away. This is simpler on uPVC frames than on aluminium or timber. If you are unable remove seals manually using a knife designed for builders to cut the seals apart until it is possible to grasp it with your fingers. After the seal has been removed, you can put in an alternative seal for the best fit and effectiveness.

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

After all the beading is gone after which you can take off the window glass. To ensure optimal thermal performance, the distance between two panes should be 12mm. Argon gas should be used to fill this space. A larger gap can be used to reduce noise levels however it can reduce the insulation capacity of windows.

It's a great idea to spray the window cleaner on the frame after it's been cleaned. This will allow the DGP stick better. This stops the tape from immediately adhering to the glass, and gives you a chance to position it correctly. To avoid damage, you should wipe the seals of the rubber using a soft rag and warm soapy water.

Re-seal the window

It may be time to reseal your double-glazed windows if you find that they are smudged up or have moisture between them. This is a clear indication that the seal on the inside has failed to keep the insulation gases in. It is not uncommon to find the rubber seal that holds in the gases that are insulating to break down in time or because of inadequate installation.

A skilled window specialist will seal each gap by applying a new seal. The technician will use silicone caulk to close the gaps. This will keep cold winter air out and the warm indoor air in. The caulk also stops bugs from getting into your home, and will stop moisture from getting into your home too.


It is important to remember that resealing a double glazed window is not a DIY project but it is feasible to tackle it yourself.

The misty windows are often a sign of a failed treatment of the glass in the factory. The factory will treat the window with a low emissivity coating to reflect heat away and it might inject an argon gas to provide additional insulation. When these treatments fail, moisture is allowed into the gap between the glass panes and it can cause condensation. This problem can be fixed by a professional who drills tiny holes through the glass panes and then pipe in a dehydrating solution to remove the moisture. They will then fill the space with a fresh insulating gas and reseal the hole without letting the gas escape.
