Double Glazed Window Repairs

Double glazing can be a fantastic investment for your home, but it can be a hassle if it fails to function properly. Most issues can be fixed and you don't need to replace windows or doors.

Double-glazed windows are made up of two glass panes that are separated by a small gap. The gap is filled with an insulating gas such as argon. This makes windows more efficient.

Broken panes

Double-pane windows are difficult to break than single-pane glass, they may break or shatter. When a pane becomes broken in your double-glazed windows, it's essential to repair it quickly to avoid loss of energy and moisture.

You can select either a temporary repair or more intensive epoxy fix depending on the severity of your crack. A temporary repair will help to prevent further cracking and can keep out rain and cold air. A more extensive repair will strengthen the crack and will provide the seal with a stronger one.

To replace a broken double-pane window, first take the frame from the sash and set it on the table. Then, put a grid of duct tape on the pane to keep any glass pieces from falling off when you remove it. Once the tape is in place then pull the old double pane glass from the frame. Then clean the grooves and rabbet with a wire brush and vacuum or wipe with a damp cloth. If necessary, remove the wood molding and scrape away all metal or putty before installing the replacement pane. Apply silicone caulk into the rabbets and grooves to ensure a secure fit.

If you're fixing a damaged glass yourself, start by sanding it until it is smooth and free of paint. Heating guns can be used to soften any putty or glazing. After the rabbet is cleaned, you can use a blade for a putty to force a rope into place. Make sure the putty is an even thickness and presses against the glass and frame evenly.

If you're looking for a longer-term fix, an epoxy repair is a better option than replacing. This option requires more work and a longer wait time, but it can be more appealing and will last longer than a short-term repair.

The steam from kettles, showers and hot pots and the cooking pans can also create humidity in bathrooms and kitchens.

Double glazing that is older may have a mist problem particularly when it occurs both in and out of the window. This is due to a malfunction of the seal designed to prevent 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 a spacer bar. This seal is designed to stop the window from leaking, and also provide insulation. If you have misted double-glazed windows, it may be difficult to remove and clean, since you'll have to break through the hardened seal to clean.

The problem with mist is that it allows moisture to enter, which ultimately results in condensation between the panes of glass. This is because there is huge differences in temperature between the external and internal surfaces of the glass. The moisture is encased in the spaces, creating a milky appearance. This can be quite unsightly and can be a pain to get rid of.

Some companies claim that they can repair misting double-glazed windows by drilling holes into the unit and injecting chemical through the holes that absorbs moisture from the inside. However, this is not a permanent solution to the issue and it is far easier to replace the entire double-glazed unit in the event that you are suffering from misting.

The easiest way to prevent misty double glazing is by maintaining a high level of ventilation and regularly cleaning your windows. Utilize extractor fans to lessen the buildup of moisture in kitchens and bathrooms. Wipe down windows with a damp cloth to avoid this.
