Repairing Double Glazed Windows
When double-glazed windows "blow", the insulating gas argon escapes, which causes them to lose their energy efficiency. The good news is that blown double glazing can be repaired without the need to replace your windows completely.
Condensation or moisture in between your double-glazed windows is the most frequent sign that the seals on your windows have failed. This can be easily fixed by a professional, which will save you the cost of a replacement window.
Remove the Sash
Double-glazed windows can add value and style to your home. They can improve the efficiency of your home's energy use by keeping the heat and cold out. With Minnesota's harsh winters, having double-glazed windows will aid in reducing your heating costs.
The main difference between single and double glazed windows is that the gap between the glass panes is filled with air or an inert gas such as argon. This makes a huge difference to the insulating properties of your windows as they stop the transfer of heat through the glass. By selecting an inert low-conductivity gas like argon or krypton to fill your windows, you can increase their insulation capabilities.
Another benefit of having double-glazed windows is that they are much more secure than single paned windows. They are more resistant to breaking and can be fitted with modern security locking systems. They can be fitted with toughened or laminated 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 option for older homes.
Additionally, double-glazed windows can also be made using low-energy glass that reduces UV rays entering your home. window repairs can help ensure that your carpets, paintings and furniture from discoloration. This is particularly helpful for windows that are in direct sunlight for the majority of the time of.
Another reason why homeowners choose to have their older sash windows retrofitted with double glazing is that they are a lot more affordable than installing new windows. The exterior linings, cladding and opening mechanisms of your current windows are not damaged, so the work is less demanding.
Additionally, the installation of double glazed windows is much faster than removing and replacing a whole window. This means you can get the benefits of energy-efficiency, enhanced security, reduced glare, and UV damage to your furnishings at a lower 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 an air spacer. This provides insulation. This is known as an insulated unit (IGU) which is filled with gases like argon or Krypton, can offer even more insulation. As time passes these units may become damaged and fail to function correctly. It is important to remove any broken glass as securely and quickly as possible.
Replacing double-glazed windows can be a challenging DIY job that requires specialised tools and expertise. This is why it's typically best left to a professional who can utilize the appropriate safety equipment and follow the proper procedure to prevent injuries.
This is especially important because double-glazed windows are very fragile and easily break or even crack. To protect yourself while repairing your window, put on gloves that are protective and wear a respirator or mask. Also, ensure that the area around the frame is clean and free of any debris. You should also put a thick piece of plastic over the place where the deglazing tool is going to score to capture any broken pieces of glass and make them easier to remove.
Aside from replacing broken glass, it's essential to check for indications that your double-glazed windows aren't functioning properly. A window that is draughty is one of the most frequently observed signs that your IGU has blown and is no longer able to provide the proper insulation. It is also possible to notice if the windows are cloudy or there is condensation between them.
In addition to saving energy costs, having efficient double glazing can also help safeguard your furniture from light and heat. Furniture may deteriorate or break if it is exposed to intense sunlight for a long time. Double-glazed windows keep your furniture safe from the sun and decreases the amount of heat entering your home.
In addition to being a great option to reduce electricity costs, efficient double glazing can also increase the value of your home. Installing double glazing is a good investment if you intend to sell your house in the future.
Remove the gaskets
Double glazing is a great method to boost the energy efficiency of your home, but it will wear out over time. The visible signs of damage, draughts and condensation are all indicators that it's time to fix or replace your double glazed windows.
The most important component of the window assembly is the gasket, a butyl or neoprene seal that cushions the glass and provides weather protection. Gaskets that are damaged are a common cause of leaks and moisture infiltration into buildings. Fortunately, these seals can be replaced without having to replace the entire window.
Gaskets are often repaired by making them tight and pulling them out. This is simpler on uPVC frames than on aluminium or timber. If you're unable to remove seals on your own using a knife designed for builders to cut the seals apart until you are able to grasp it with your fingertips. After the seal is removed, you can apply an alternative seal for a tighter fit and maximum effectiveness.
Once the seals are replaced the window beading has to be removed. You can use a putty or lead knife to remove the window beading. The blade should be placed between the frame and the bead in the middle of longest bead. This will give you the most leverage to separate the bead from the frame.
After all of the beading has been removed after which you can take off the window glass. The gap between the two panes should be around 12mm, and it is important to fill this space with Argon gas to ensure optimal thermal performance. It is possible to increase the distance between your panes to reduce noise, but this can affect the insulation properties of your windows.
Once the frame is cleaned, it's a good idea to spray the frame with window cleaner prior to placing the DGP. This will stop the tape from sticking to the glass instantly, giving you time to position it correctly. It's also worth wiping down the seals made of rubber with a soft cloth and warm soapy water to avoid any damage.
Re-seal the Window
It could be time to replace the seal on your double-glazed windows if notice that they're fogged up or have moisture between them. These kinds of issues are a clear indication that the seal in the interior is failing to keep in the insulating gas. This is not unusual as the rubber that holds in the insulating gas may be damaged due to age or improper installation.
A skilled window specialist will seal the glass unit by putting the new seal over each of the insulating gaps. The technician will then fill in the gaps with silicone caulk. This will keep cold air out and warm air in during winter. This caulk will prevent bugs from entering your home and also prevent moisture from entering.
Re-sealing double-glazed windows not an easy DIY task. However, it is possible. It is a tedious and time-consuming task that requires specialized tools to get rid of the old caulk, clean the area, then apply the new caulk. It is recommended to hire a professional glazier to do the work to avoid injury and to ensure that it is done properly.
There are instances where a double-glazed window will not be repairable and it will need to be replaced. This could be due to broken or cracked glasses, severe damage to the frame or serious decay. Ask a double-glazing specialist to determine the best option in these instances.
Oftentimes, the misting of the 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 can be introduced into the gap between the glass panes and cause condensation. This issue can be resolved by a professional by drilling tiny holes in the glass panes and then pipeing in a dehydrating solution to remove the moisture. They then fill the gap with a new insulating gas and reseal the hole without letting the gas escape.
