Repairing Double Glazed Windows

When double-glazed windows "blow", the gas that insulates them, argon, escapes, causing them decrease their energy efficiency. The good news is that blown double glazing can be repaired without having to replace your windows completely.

The main difference between double and single 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 because it blocks heat from transferring through the glass. Selecting an inert gas with low thermal conductivity such as argon or krypton will help improve the insulation properties of your windows more.

Double-glazed windows are also more secure than single-paned windows. They are less resistant to breaking and can be fitted with modern security locking systems. They can be equipped with toughened or laminated glass to make them safer. Double-glazed windows are more sturdy and less likely to rattle in the wind or due to the impact of traffic, making them a good choice for older homes.

Remove the Glass

As opposed to single pane windows double-glazed windows feature two glass panes separated by a spacer and a layer of air that provides insulation. This is known as an insulated unit (IGU) that is filled with gases like Krypton or argon, can provide even more insulation. These units can become damaged over time and stop working correctly. It is important to remove any broken glass as safely and swiftly as you can.

It is also recommended to put a thick piece of plastic over the area that the deglazing tool will score to capture any broken pieces of glass and make them easier to remove.

It's important to check for signs of double-glazed windows that aren't functioning correctly. A window that is draughty is one of the primary indicators that your IGU has blown and no longer provides proper insulation. It is also possible to notice if the windows are cloudy or there is condensation between them.

Double glazing is not only a way to reduce energy costs but also protects furniture from light and heat. Furniture can fade and break if exposed to sunlight for long periods of time, however double-glazed windows keep your furnishings out of direct sunlight, and also reduce the amount of heat that comes into your home.

Gaskets are often repaired by pinching them and removing them. It is simpler to repair uPVC frames than timber or aluminum. If you are unable to remove seals by hand using a knife designed for builders to cut the seals apart until you can grasp it with your fingers. Once the seal has been removed and replaced, you can replace it with a brand new seal to ensure a snug fit and maximum efficiency.

After the seals are replaced and the window beading is replaced, it must be removed. This can be accomplished using either a putty knife, or a lead knife. The blade should be placed between the frame and the bead at the middle of longest bead. This will give you maximum leverage to separate the frame from the bead.

After removing the beading, you can then remove the window glass. The gap between the two panes must be about 12mm and it is important to fill this space with Argon gas to ensure optimal thermal performance. A bigger gap could be used to reduce the sound levels however it can reduce the insulation performance of your windows.

After the frame is cleaned it's recommended to spray the frame with window cleaner prior to placing the DGP. This will stop the tape from sticking to the glass immediately, giving you time to ensure it's placed correctly.

A upvc window repairs specialist who is experienced will reseal the glass unit by placing a new seal around each of the individual gaps that are insulating.

The misting of windows is often a sign of a failed treatment of the glass at the factory. The factory will treat the window with a low-emissivity coating to reflect heat away, and it may pump in an argon gas to provide additional insulation. When these treatments fail, moisture gets into the gap between the glass panes and it could cause condensation. A professional can solve this issue by drilling tiny holes into the glass panes and then pipe in a dehydrating agent to remove the moisture. The expert will then fill the gap with a new gas that is insulating and seal it, without letting any gas escape.
