Why Repairing Double Glazed Windows Is Relevant 2023
Repairing Double Glazed Windows

When double-glazed windows "blow" in the wind, argon that is insulating escapes causing the window to lose its energy efficiency. The good news is, blowing double glazing is usually repaired without the need to replace the windows.

The most common sign of a failed window seal is condensation or moisture between double-glazed windows. It can be easily fixed by a professional, saving you the cost of a replacement window.

Take off the Sash

The primary distinction between single and double glazed windows is that the space between panes of glass is filled with air or an inert gas such as the gas argon. This makes a huge difference to the insulation properties of your windows because they stop the transfer of heat through the glass. Selecting an inert gas that has low thermal conductivity such as argon or krypton, helps to increase your window's insulating properties even more.

Double-glazed windows are also more secure than windows with a single pane. They are less resistant to breaking and can be equipped with modern security locking systems. They can be fitted with toughened or laminated glass to make them more secure. Double-glazed windows are more durable and less likely than single-glazed ones to shake or vibrate in the wind. They are an excellent option for older homes.

Double-glazed windows can also be constructed of low-energy glass which reduces the UV rays that penetrate your home. This will help protect your carpets, furniture and paintings from fading. This is particularly important if you have windows that are in direct sun for most of the time.

Remove the Glass

Unlike single pane windows, double glazed windows have two glass panes that are separated by a spacer and layer of air which provides insulation. The IGU, also known as an insulated glass unit (IGU) can be filled with gases such as argon or krypton for even better insulation. These units may become damaged over time and stop working properly. It is crucial to take away any broken glass as safe and quickly as possible.

window repair isn't easy to replace double-glazed windows on your own. You'll need specialist tools and experience. This is why it is usually best left to a professional who will make use of the right safety equipment and follow the correct procedure to avoid injuries.

It is important to look for signs of double-glazed windows that aren't functioning correctly. A draughty windows is one of the primary indicators that your IGU is blowing and is no longer providing adequate insulation. It is also possible to notice if the windows are cloudy or have condensation between them.

Furniture can break and fade if exposed to sunlight for long periods of time, but double-glazed windows will keep your furnishings out of direct sunlight, and also reduce the amount of heat that is brought into your home.

Gaskets can often be repaired by pressing them down and removing them. It is much easier to repair uPVC frames than aluminum or timber. If you are unable to remove seals manually then you can use a builder’s knife to pry the seals apart until you can grasp it with your fingertips. Once the seal has been removed and replaced, you'll be able to replace it with a brand new seal to ensure a tight fit and maximum efficiency.

Once the seals are replaced the window beading will need to be removed. You can use a putty or lead knife to remove the window beading. Place the blade of the knife between the frame and the bead in the middle of the longest bead. This will give you the maximum leverage to remove the frame from the bead.

After removing the beading you can take off the glass. To ensure optimal thermal efficiency, the gap between two panes should be 12mm. Argon gas should be utilized to fill this gap. A bigger gap can be used to lower noise levels however it can reduce the insulation performance of windows.

After the frame has been cleaned it is a good idea to spray it with window cleaner before fitting the DGP. This will stop the tape from adhering to the glass immediately, giving you time to position it correctly. To avoid damage, it's recommended to wipe the seals of the rubber using a soft rag and warm soapy water.

A professional window specialist will seal the glass unit by placing an entirely new seal around each of the individual gaps of insulation. The technician will then fill in the gaps with silicone caulk. This will keep the cold winter air out and the warm air inside. The caulk will also stop bugs from entering your home, and it will prevent moisture from getting into your home too.

Re-sealing double-glazed windows not a DIY-friendly task. However it is doable.

The misty windows are often an indication of a failing treatment of the glass in the factory. The factory will apply a low-emissivity coating on the window to reflect heat. It could also inject an argon gas for additional insulation. If these treatments fail, moisture could get into the space between the glass panes and cause condensation. This issue can be solved by a professional who drills tiny holes through the glass panes, then pipeing into a dehydrating solution to eliminate the moisture. They then fill the gap with a fresh insulating gas and reseal the gap without letting the gas escape.
