Repairing Double Glazed Windows

When double-glazed windows "blow", the gas that insulates them, argon, escapes, causing them decrease their energy efficiency. The good thing is that double glazing is often repaired without the need to replace your windows completely.

Moisture or condensation in between your double-glazed windows is the most frequent sign that your window seals have failed. It can be easily repaired by a professional, saving you the expense of a replacement window.

Remove the Sash

Double-glazed windows are a fantastic option to enhance the look and value of your home. They improve the energy efficiency of your home by keeping the cold and heat out. Double-glazed windows can help you save money on heating bills in Minnesota's winters that are brutal.

The primary distinction between single and double glazed windows is the gas that is injected into the space between the panes of air or argon. This can make a significant difference to your windows' insulation capabilities by preventing heat from transferring through the glass. Choosing an inert gas with a low thermal conductivity, such as argon or krypton, helps to increase the insulating properties of your windows more.

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

In addition, double-glazed windows can also be made using low energy glass which reduces the amount of UV rays that enter your home. This will safeguard your furniture, carpets and paintings from becoming faded. This is especially beneficial for windows that are exposed to direct sunlight for much of the day.

Retrofitting a sash window that is old with double-glazed windows is cheaper than purchasing new windows. The cladding, internal linings and opening mechanisms of the existing windows remain intact, so the work is less intrusive.

Double-glazed windows are more efficient than removing a window and replacing it. That means that you can enjoy the benefits of energy efficiency, increased security and reduced glare and UV damage to your furnishings for an even better price.

Remove the Glass

In contrast to single pane windows double-glazed windows feature two glass panes separated by a spacer and layer of air that provides insulation. This 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 correctly. In the event of this, it's important to remove the damaged glass as quickly and safely as you can.

It isn't easy to replace double-glazed windows on your own. You will need specialised tools and experience. It is best to delegate this job to a professional who will employ the correct safety equipment and follow the proper procedure to avoid injuries.

It is important to do this since double-glazed windows are extremely fragile and easily crack or break. To safeguard yourself when repairing your window, wear gloves that are protective and wear a respirator or mask. Make sure the area around the window frame is free of any debris and clean. In addition, you must put a thick layer of plastic over the frame which will be cut by the deglazing tool in order to catch the fragments of glass that have broken and make it easier for you to take them away.

Apart from replacing broken glass, it's important to find signs that your double glazed windows aren't working properly. Draughty windows are one of the primary indicators that your IGU is blowing and no longer provides proper insulation. You may also notice that the windows are cloudy or there is condensation between them.

Double glazing is not only an option to save money on energy bills but also to shield your furniture from light and heat. Furniture can deteriorate and break when exposed to sunlight for prolonged periods of time, however double-glazed windows will keep your furniture out of direct sunlight and will reduce the amount of heat that comes into your home.

Double glazing that is energy efficient can increase the value of a property. Double glazing is a great investment if you plan to sell your home in the near future.

Remove the Gaskets

Double glazing is a popular choice to boost the efficiency of your home's energy use however, as with all things, it can be prone to wear and tear. Damages that are visible, draughts, and condensation are all indicators that it's time to repair or replace your double glazed windows.

The gasket is a key component of the window assembly. It is a neoprene rubber seal that cushions and protects the glazing from the weather. Deterioration of the gaskets is the main reason for leaks and the infiltration of moisture into buildings. Fortunately, these seals can be replaced without having to replace the whole window.

Most often, gaskets can be repaired by pinching and pulling them off. This is simpler on uPVC frames than on timber or aluminium. If you are unable to remove seals manually then you can use a builder’s knife to pry the seals apart until you are able to grasp it using your fingertips. After the seal is removed and replaced, you can replace it with a brand new seal to ensure a tight fit and maximum efficiency.

After the seals have been replaced the window beading has to be removed. You can employ a lead or putty knife to remove the window beading. The blade should be placed between the frame and the bead at the middle of the longest bead. This will give you the maximum leverage to cut off the frame from the bead.

After removing the beading, you can remove the window glass. The gap between the two panes should be about 12mm and it's important to fill it with Argon gas to ensure optimal thermal performance. It is possible to increase the distance between your panes to lower noise, but this could affect the insulating properties of your windows.

Once the frame has been cleaned it is recommended to spray it with window cleaner before fitting the DGP. This will stop the tape from adhering to the glass instantly, giving you time to position it correctly. It's also a good idea to wipe the seals made of rubber with an absorbent cloth and warm soapy water to prevent any damage.

Re-seal the Window

If you notice that your double glazed windows are getting cloudy or there is condensation between the panes, then it may be time to replace them. This is a clear sign that the seal inside has failed to keep the insulation gases in. This is not unusual and the rubber that holds in the insulating gas can be damaged due to age or improper installation.

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

It is important to remember that resealing an existing double-glazed window is not a DIY job but it is feasible to tackle it yourself. It is a lengthy and laborious job that requires special tools to take off the old seal, clean the area and put in a fresh caulk. It is recommended to get a professional glazier to do the job to avoid injury and to ensure that it is done correctly.

There are some cases where a double-glazed window cannot be repaired and will have to be replaced. This could be due to cracked or shattered glasses, severe damage to the frame or replace severe decay. It is a good idea to consult an expert in double glazing to determine what the best option is in these instances.

The misting of windows is usually an indication of a failing treatment of the glass at the factory. The factory will put a low-emissivity coating to the window to reflect heat. It may also pump in the argon to provide additional insulation. If these treatments fail, moisture is allowed to enter the space between the glass panes and it could cause condensation. A professional can solve this issue by drilling tiny holes in the glass panes, replace and then injecting an agent that dehydrates to eliminate the moisture. They then fill the hole with a new insulating gas and reseal the hole without letting the gas escape.
