17 Signs You're Working With Double Glazed Window Repair Double Glazed Window Repairs

Double glazing is a great investment for your home, but it can be frustrating when it fails to function properly. Most problems can be repaired and you don't need to replace your windows or doors.

Double-glazed windows consist of two glass panes that are separated by a very thin gap. The gap is then filled with an insulating gas, such as the gas argon. This increases a window's efficiency.

Broken panes

While double-pane windows are more difficult to break than single-pane glass, they are still able to crack or shatter. It is important to repair the broken pane of double glazing as quickly as possible to avoid moisture and energy loss.

Depending on the extent of the crack you may decide to make a temporary repair or more extensive repair using epoxy. A temporary repair will help to stop further cracks from occurring and keep out rain and cold air. A more extensive repair will strengthen the crack and provide a stronger seal.

To replace a damaged double-pane windows, first remove the frame from the sash and set it on the table. Then, place a grid of duct tape on the pane to keep glass pieces from falling off when you remove it. After the tape has been applied, remove the old double-pane glass from the frame. Then, use a wirebrush to clean the grooves and rabbets. You can also vacuum or wipe them clean with a damp cloth. If needed, take off the wood molding and scrape away all metal or putty before putting in the new pane. Apply a silicone caulk to the grooves and rabbet to ensure that the fit is secure.

If you're planning to repair a cracked window yourself, begin by sanding the rabbet until it's smooth and free of paint or gunk. You can also use a heat gun to soften any putty or glazing points. Once the rabbet has been cleaned then you can use a putty knife to press a rope into place. Make sure that the putty is uniform in thickness and press against the glass and frame evenly.

If you're looking for a longer-term fix the repair of an epoxy is a better option than replacing it. This option is more expensive and has a longer waiting period, but can be more attractive. It also lasts longer than a temporary repair.

Condensation

Condensation can be a common problem with double-glazed windows, however, it doesn't mean that they are defective. The fact that your windows show condensation is a good indication that your double glazing is doing what it's supposed to do, keeping cold out and letting the warmth in.

The reason for condensation inside is usually a lack of humidity or low temperatures in the room. This creates cold surfaces, such as windows which draw in moisture that is high dewpoint (the temperature where water turns into a liquid). The steam from showers, kettles and hot pots as well as saucepans used in cooking can also cause a lot of humidity around kitchens and bathrooms.

Avoid hanging wet clothing close to windows, and make sure your uPVC frames are properly ventilated to prevent moisture buildup. You should also make sure that your double-glazed windows are correctly insulated and installed with the proper gap (6mm is ideal) for optimum energy efficiency. You can also try adding one-way air vents to your windows to improve insulation. If you're still seeing condensation,, then there's likely an issue with gaskets or seals and this is definitely a job for an expert.

Foggy or fogged glass is caused by the presence of moisture between the panes. It's usually a sign that the seals are faulty or that the double-glazing system needs to be replaced. This is a straightforward fix that can be accomplished without having to replace the whole window.

To correct this issue, a technician will make tiny holes to let out any moisture that is trapped between the glass panes and other parts of the window. Once the moisture has been removed, a new antifog coating is put on and the window is sealed. Sometimes, the window will require removal prior to this can happen however the majority of the time, it is done from inside the home.

Mist

Double glazing that has been in use for a long time may have a mist issue, especially when it happens both inside and outside the window. This is because of a weakening of the seal that is designed to block air and moisture between the two panes. This seal is constructed when making double-glazed units by sealing the two panes using an airtight polysulphide or butyl seal around the edges and spacer bar. This seal is designed to keep the window from leaking and to provide insulation. If you have misted double glazed windows it can be a challenge to remove and clean, as you'll need to break the hardened seal in order to clean.

The problem with mists is that they allow moisture to enter and cause condensation between the glass panes. This is due to an enormous temperature difference between the internal and external surfaces of the glass. The water is then absorbed within the spaces and gives a milky white appearance. This can be very unsightly and difficult to remove.

Some companies claim they can fix misting double-glazed windows by drilling holes in the unit and injecting chemicals through the holes that absorbs moisture from the inside. But, this isn't a permanent solution to the issue and it's much easier to replace the entire double-glazed unit if experiencing misting.

The most effective method to avoid misty double glazing is maintaining a high level of ventilation and cleaning your windows regularly. It's also an excellent idea to install extractor fans in bathrooms and kitchens, and wipe down windows with a damp cloth to reduce the accumulation of moisture. If you're unable to completely avoid the issue we suggest replacing your double-glazed units with new A-rated ones to boost the efficiency of your energy usage.
