The Little-Known Benefits Of Repairing Double Glazed Windows
Repairing Double Glazed Windows

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

The most frequent sign of a failed window seal is moisture or condensation between double-glazed windows. A professional can fix this, saving you from needing to replace the window.

Remove the Sash

Double-glazed windows can add value and style to your home. They increase the energy efficiency of your home by keeping heat and cold out. With Minnesota's harsh winters having double glazed windows will help reduce your heating bills.


The main distinction between single and double glazed windows is that the space between panes of glass is filled with either air or an inert gas, such as argon. This is a significant improvement in the insulation properties of your windows since they block the transfer of heat through the glass. Selecting an inert gas that has low thermal conductivity like argon or krypton which can help increase your window's insulating properties even further.

Another benefit of double-glazed windows is that they are more secure than single paned windows. They are harder to break and can be fitted with modern security locking systems. They can be equipped with toughened or laminated glass to make them more secure. Double glazed windows are more sturdy and less likely to shake in the wind or because of the vibrations of heavy traffic and are a good choice for older homes.

In addition, double-glazed windows can be constructed with low energy glass, which can reduce UV rays entering your home. This will help safeguard your furniture, carpets and paintings from fading. This is especially useful for windows that are directly in the sunlight for the majority of the time of the day.

As an added bonus the process of installing double glazed windows is much quicker than the process of removing and replacing a complete window. This means you can benefit from energy efficiency, improved security, and less glare and UV damage to your furnishings for an even better price.

Remove the Glass

Double-glazed windows differ from single pane windows in that they have two glass panes separated by an air layer and a spacer. This provides insulation. The IGU, also known as an insulated glass unit (IGU) can be filled with gases such as argon or krypton for even more insulation. These units are susceptible to being damaged as time passes and stop functioning properly. In the event of this it is crucial to take away the broken glass as fast and safely as is possible.

It can be difficult to replace double-glazed windows on your own. You will need specialised tools and experience. This is why it is typically best left to a professional who will make use of the right safety equipment and follow the proper procedure to avoid 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 frame that will be scored by the deglazing tool to catch the fragments of glass that have broken and make it easier for you to remove them.

Apart from replacing broken glass, it's essential to look for signs that your double glazed windows aren't functioning properly. A draughty window is among of the most frequently observed signs that your IGU has blown and is no longer providing proper insulation. It is also possible to determine whether your windows are cloudy or if t here is condensation between them.

Besides being able to save money on energy bills, having efficient double glazing can also help safeguard your furniture from heat and light. Furniture can fade and break when exposed to sunlight for long periods of time, however a double-glazed window will keep your furnishings out of direct sunlight and will reduce the amount of heat that is brought into your home.

Double glazing that is energy efficient can increase the value of a property. Double glazing is a wise investment if you intend to sell your house in the future.

Remove the gaskets

Double glazing is a great method of increasing the energy efficiency of your home, but it can wear out over time. Double glazed windows that show visible damage, have draughts or are susceptible to condensation must be fixed or replaced.

The gasket is a crucial element of the window assembly. It is a neoprene seal that cushions and shields the window from the elements.

Often, the gaskets can be repaired by pinching them and pulling them away. This is simpler on uPVC frames than on aluminium or timber. If you're unable remove the seals by hand it's best to use a builder's knife to cut off the seal until you're able to grasp it with your fingers. Once the seal has been removed, you can replace it with a new seal to ensure a tight fit and maximum efficiency.

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

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

It's a good idea to spray the window cleaner on the frame after it's been cleaned. This will assist in helping the DGP stick better. This prevents the tape from immediately adhering to the glass, and gives you a chance to position it in the right way.

It is not uncommon for the rubber seal that holds in the insulating gases to wear out as time passes or due to inadequate installation.

A window specialist who is experienced will seal the glass unit by putting a new seal around each of the gaps that are insulating. The technician will then fill in the gaps with silicone caulk.

The misting that occurs on 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 an argon gas to provide additional insulation. If these treatments fail, moisture gets into the gap between the glass panes and it can cause condensation. This issue can be solved by a professional who drills tiny holes through the glass panes and then piping in a dehydrating solution to eliminate the moisture. They then fill the space with a fresh insulating gas and reseal the hole without letting the gas escape.
