Repairing Double Glazed Windows

Double-glazed windows "blow" in the wind, the gas that insulates them, argon, escapes, causing them decrease their energy efficiency. The good news is that blown double glazing is often repairable without having to replace the windows.

Selecting an inert gas that has a low thermal conductivity, such as argon or Krypton which can help increase the insulation properties of your windows further.

Double-glazed windows are also more secure than single-paned windows. They are more difficult to break and can be fitted with modern security locking systems installed. They can be fitted with toughened or laminated glass to make them even safer. Double-glazed windows are more sturdy and less likely to rattle in the wind or due to vibrations from heavy traffic and are a good choice for older homes.

In contrast to single pane windows double glazed windows have two glass panes 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 like Krypton or argon to provide better insulation. These units can become damaged over time and stop working correctly. It is crucial to take away any broken glass as securely and swiftly as you can.

It can be difficult to replace double-glazed windows on your own. You'll need specialist tools and expertise. It is best to delegate the job to a professional who will make use of the appropriate safety equipment and follow the correct procedure to avoid injury.

Gasket degradation is a leading cause of leaks, and moisture entering buildings. Fortunately, these seals can be replaced without having to replace the entire window repair.

Gaskets are often repaired by pinching them and removing them. This is much easier on uPVC frames than on timber or aluminium. If you're unable to remove seals manually using a builder’s knife to pry the seals apart until it is possible to grasp it using your fingertips. After the seal is removed, you can replace it with a 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 use a putty or lead knife to remove the window beading. Insert the blade between the frame and the bead at the middle of longest bead. This will give you the maximum leverage to separate the bead from the frame.

After removing the beading, you can take off the glass. The gap between the two panes should be around 12mm, and it's crucial to fill it with Argon gas to ensure optimal thermal performance. It is possible to increase the distance between your panes to reduce noise, however this could affect the insulating properties of your windows.

The misting of windows is often an indication of a poor treatment of the glass at 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. When these treatments fail, moisture is allowed into the gap between the glass panes, and it can cause condensation. A professional can solve this problem by drilling tiny holes in the glass panes, and then injecting a dehydrating agent to remove the moisture. The expert will then fill the gap with a brand new gas insulating the area and seal it, without the gas from escaping.
