Repairing Double Glazed Windows

Double-glazed windows "blow" they let the gas that insulates them, argon, escapes, causing them to lose their energy efficiency. The good news is, damaged double glazing is typically repaired without the need to replace the windows.

Condensation or double glazing moisture in between your double-glazed windows is a typical indication that the seals on your windows have failed. A professional can repair this, preventing you from having to replace your window.

Take off the Sash

Double-glazed windows are a fantastic option to add style and value to your home. They can improve the energy efficiency of your home by keeping cold and heat out. With Minnesota's harsh winters, having double-glazed windows will help you save on heating costs.

The primary distinction between single and double glazed windows is that the gap between the glass panes is filled with either air or an inert gas, like argon. This can make a significant difference to the insulation properties of your windows, as it prevents heat from transferring through the glass. By choosing an inert, low-conductivity gas, such as Krypton or argon to fill your windows, you will increase their insulation capabilities.

Another benefit of having double-glazed windows is that they are more secure than single pane windows. They are much more difficult to break and can be equipped with modern security locking systems. They can be equipped with toughened or laminated glass to make them more secure. Double glazed windows are more robust and less likely to rattle in the wind or from vibrations from heavy traffic which makes them a great choice for older homes.

Additionally, double-glazed windows can be made with low energy glass which reduces UV rays entering your home. This can protect your carpets, paintings and furniture from becoming faded. This is especially useful for windows that are directly in the sunlight for the majority of the time of the day.

Another reason that homeowners choose to have their old sash windows retrofitted with double glazing is that they are cheaper than the installation of new windows. The interior linings, cladding, and opening mechanisms of your existing windows are still in place, which means the job is much less intrusive.

In addition, the installation of double glazed windows is much quicker than the process of removing and replacing a window in its entirety. That means that you can enjoy the benefits of energy efficiency, enhanced security and reduced glare and Double glazing UV damage to your furniture at a lower cost.

Remove the Glass

Double-glazed windows differ from single pane windows in that they are made up of two glass panes, separated by an air layer and the spacer. This provides insulation. This is known as an insulated unit (IGU) that is filled with gases such as argon or Krypton, can provide even better insulation. As time passes, these units can become damaged and fail to perform as they should. It is important to remove any broken glass as safely and efficiently as is possible.

It isn't easy to replace double-glazed windows on your own. You'll need specialist tools and experience. This is why it's usually best left to a professional who will utilize the appropriate safety equipment and follow the proper procedure to avoid injuries.

It is essential to do this since double-glazed windows can be very fragile and are prone to crack or break. Wear a respirator or mask and gloves to safeguard yourself when working on the window. You should also make sure that the area around the frame is free of debris. It is also recommended to put a thick piece of plastic over the place where the deglazing tool will score to capture any broken pieces of glass and make them easier to remove.

It is crucial to identify indications that double-glazed windows aren't functioning properly. A draughty windows is one of the main signs that your IGU has blown and no longer provides proper insulation. You can also see the windows are cloudy, or whether there is condensation between them.

Besides being able to save money on energy bills, having efficient double glazing can also help keep your furniture safe from light and heat. Furniture can break and fade if exposed to sunlight for extended periods of time. However, a double-glazed window will protect your furniture from direct sunlight, and also reduce the amount of heat that enters into your home.

Double glazing that is energy efficient can increase the value of your property. If you're looking to sell your home in the future installing double glazing is a smart investment that can help attract prospective buyers.

Remove the Gaskets

Double glazing is an excellent method of increasing the energy efficiency of your home, but it will wear out over time. Visible damage, draughts and condensation are all signs that it's time to repair or replace your double glazed windows.

A crucial component of the window assembly is the gasket, which is a butyl or neoprene rubber seal that cushions the glazing and provides weather protection. Gasket wear is a major cause of leaks, and water getting into buildings. Fortunately, these seals can be replaced without having to replace the whole window.

The gaskets are often able to be repaired by pinching and pulling them away. This is much easier on uPVC frames than on timber or aluminium. If you're unable to remove the seals manually it's best to use a knife to remove the seal until you're able to grasp it with your fingers. After the seal is removed and replaced, you can replace it with a new seal to ensure a secure fit and maximum efficiency.

After the seals have been replaced and the window beading is replaced, it must be removed. You can employ a lead or putty knife to remove the window beading. Insert the blade of the knife between the frame and bead in the middle of the longest bead. This will give you the greatest leverage to separate the bead from the frame.

After removing the beading, you can remove the glass. To ensure optimal thermal efficiency, the gap between two panes needs to be 12mm. Argon gas should be used to fill this space. A larger gap could be used to reduce the sound levels however it will decrease the insulation capacity of your windows.

After the frame has been cleaned it's 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 immediately, giving you time to position it correctly. To prevent any damage, you should wipe the seals with a soft cloth and warm soapy water.

Re-seal the Window

If you notice that your double glazed windows are fogging up or you notice that there is water between the panes it could be the right the time to seal them. This kind of issue is a clear sign that the seal on the inside has failed to keep the insulation gases in. It is not unusual for the seal made of rubber that holds in the gases that are insulating to break down as time passes or due to inadequate installation.

A professional window specialist will reseal the glass unit by putting a new seal around each of the individual gaps of insulation. The technician will fill the gaps with silicone caulk. This will keep the cold winter air out while allowing the warm indoor air in. This caulk will stop insects from getting into your home and will also stop moisture from getting in.

Re-sealing double glazed windows is not a simple DIY project. However it is doable. It is a difficult and time-consuming job that requires specialized tools to remove the old caulk, clean the area, and apply the new caulk. It is recommended to hire a professional glazier for the work to avoid injury and to ensure that it is done properly.

There are certain situations in which a double-glazed window doctor is not repairable and will have to be replaced. This could be due to broken or cracked glasses, severe damage to the frame or severe decay. It is a good idea to consult with a double glazing expert to find out what the best solution is in these instances.

Often, the misting of windows is 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 might inject the gas argon to provide insulation. When these treatments fail, moisture gets to enter the space between the glass panes, and it could cause condensation. A professional can address this problem by drilling tiny holes into the glass panes and pipe in a dehydrating agent to get rid of the moisture. The expert will then fill the gap with a brand new insulating gas and seal it, without let any gas escape.
