Repairing Double Glazed Windows

When double glazed windows "blow" the insulating argon escapes causing the window to lose energy efficiency. The good news is that blown double glazing can be repaired without having to replace your windows completely.

The most common sign of a damaged window seal is moisture or condensation between double-glazed windows. It can be easily repaired by a professional, which will save you the cost of a new window.

Remove the Sash

Double-glazed windows can add value and elegance to your home. They improve the efficiency of your home's energy usage by keeping the cold and heat out. With Minnesota's harsh winters, double-glazed windows can aid in reducing your heating costs.

The primary difference between double and single windows is the gas that fills the space between panes of air or argon. This can make a big difference to your windows' insulation capabilities, as it prevents heat from moving through the glass. Choosing an inert gas with a low thermal conductivity, like argon or krypton which can help increase your window's insulating properties even more.

Another benefit of having double-glazed windows is that they are much more secure than single paned windows. They are less difficult to break and can be fitted with modern security locking systems. They can also be equipped with laminated or toughened glass, making them even more secure. Double glazed windows are more durable and less likely to shake in the wind or because of vibrations from heavy traffic, making them a good option for older homes.

Double-glazed windows can also be made of low-energy glass, which blocks UV rays that enter your home. This can help safeguard your furniture, carpets and paintings from fading. This is especially beneficial for windows that are in direct sunlight for a large portion of the day.

Another reason why homeowners opt to have their old sash windows retrofitted with double glazing is that they are a lot less expensive than installing new windows. The exterior linings, cladding and opening mechanisms of your current windows are still in place, which means the work is less demanding.

Double-glazed windows can be installed faster than taking a window off and replacing it. This means that you will enjoy the benefits of energy efficiency and enhanced security, as well as less glare, and UV damage to your furniture for a less cost.

Take the Glass off

Double glazed windows are different from single pane windows in that they feature two glass panes, separated by an air layer and a spacer. This provides insulation. This is known as an insulated unit (IGU), which is filled with gases such as Krypton or argon, can offer even more insulation. In time these units may be damaged and cease to perform as they should. It is important to remove any broken glass as safe and quickly as 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 often best left to a professional who can utilize the appropriate safety equipment and follow the correct procedure to avoid injuries.

To safeguard yourself when repairing your window, wear a pair of protective gloves and wear a respirator or mask. Make sure the area surrounding the window frame is free of debris and clean. Finally, you should put a thick layer of plastic over the frame which will be cut by the deglazing tool to capture the pieces of glass that have broken and make it easier to remove them.

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 is blowing and is no longer able to provide the proper insulation. You can also see if your windows are cloudy or if there is condensation between them.

Double glazing is not only an opportunity to reduce energy costs but also protect your furniture from heat and light. Furniture can break and fade if exposed to sunlight for extended periods of time, but double-glazed windows keep your furnishings out of direct sunlight and reduce the amount of heat that is brought into your home.

Double glazing that is energy efficient can enhance the value of a home. If you're planning to sell your home in the near future installing double glazing is a great investment that will draw potential buyers.

Remove the gaskets

Double glazing is a popular choice to increase your home's energy efficiency however, as with all things it is susceptible to wear and tear. The visible signs of damage, draughts and condensation are all indicators that it's time to repair or replace your double-glazed windows.

A key part of the window assembly is the gasket, a butyl or neoprene rubber seal that cushions the glass and provides weather protection. Deterioration of the gaskets is the most common cause of leaks and near moisture infiltration into buildings. The seals can be easily replaced without the need to replace the entire window.

Gaskets are often repaired by pressing them down and pulling them out. This is easier to do on uPVC frames than on aluminum or timber. If you are unable to remove seals on your own using a knife designed for builders to cut the seals apart until you can grasp it with your fingertips. Once the seal is removed, you can apply the new seal to ensure the best fit and effectiveness.

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

After all the beading has been removed and the window glass is removed, you can remove the glass. The gap between the two panes must be about 12mm and it is important to fill the gap with Argon gas for optimum thermal performance. It is possible to increase the gap between your panes in order to reduce noise, however this will decrease the insulating properties of your windows.

It's a good idea to spray the window repair cleaner on the frame after it has been cleaned. This will allow the DGP stick better. This stops the tape from instantly sticking to the glass, allowing you the chance to place it in the right way. To avoid any damage, it's worth wiping the seals of the rubber using a soft rag and a warm soapy liquid.

Seal the window

If you notice that your double-glazed windows are fogging up or there is water between the panes it could be the right the time to seal them. These kinds of issues are a clear sign that the seal inside isn't able to hold in the insulating gas. It is not unusual to find the rubber seal that keeps in the insulating gases to wear out in time or because of improper installation.

A skilled window specialist will reseal each individual gap by applying a fresh seal. The technician will then fill in the gaps with silicone caulk. This will keep cold air out and the warm air in during winter. The caulk will also stop bugs from entering your home, and it will prevent moisture from entering your home as well.

Re-sealing double-glazed windows not a DIY-friendly task. However, it is possible. This is a time-consuming and laborious task that requires specialized tools to remove the old seal, then clean the area and put in a fresh caulk.

In some cases, a double-glazed glass window is not repairable and must be completely replaced. This could include cracked or shattered glass, significant damage to the frame, or serious decay. Consult a double-glazing expert to determine the best option for these scenarios.

Oftentimes, the misting of windows is an indication that the treatment of the glass in the factory has failed. The factory will apply a low-emissivity coating to the window to reflect heat and may also inject an argon gas for additional insulation. When these treatments fail, moisture can be allowed into the gap between the glass panes, and it may cause condensation. A professional can address this issue by drilling tiny holes into the glass panes and then piping in a dehydrating agent to remove the moisture. The professional will then fill the gap with a brand new gas insulating the area and seal it, without the gas from escaping.
