Repairing Double Glazed Windows
Double glazing is a great investment for your home. In time, it may cause problems such as misting or condensation.
The cause can be due to various reasons, but it's usually due to the seals not being airtight. This leads to a loss of the gases that insulate that sit between the glass panes. Knowing how to repair your double glazing will assist.
Broken Panes
A stray ball from the lawnmower or a stone thrown at it even a cat's claw can cause a double-glazed window to shatter. This allows heat or cold to pass more easily between two layers of glass, which can result in lower insulation and increasing energy bills. It's time to replace both windows if broken.
However, if one of the panes is damaged, but not completely broken, it may still be possible to repair it. The first step is to take the old pane from the frame wearing gloves and a pair of work glasses. Remove the putty that is loose from the broken edges of the glass using a painter’s tool, which you can warm using the help of a heat gun. Use aluminum foil to prevent adjacent panes from cracking while the putty is being removed.
When the frame is ready for the new pane, you need to lubricate the cutter on an inexpensive glass cutting tool -- available at most hardware stores -- using light oil such as WD-40. Cut along the edges of the glass, roughly one inch from the edge. Then, gently move the glass into the rabbets, or the grooves that form an l in the window frame, where it will sit. Then utilize the tool's chiseled tip to remove any remaining putty from the edges of the glass.
When the new pane has been put installed, press glazier's points into the frame every six inches around the seam where it meets the glass. Then apply another cord of glazier's compounds to the frame-glass joint and smooth it out using the putty knife. If your windows are made of metal, paint the joints with an anti-rust primer specifically designed specifically for your particular type of metal.
Cracks
Although it is not common the possibility of a cracking in your double glazing may occur - particularly in older windows. The reason is usually due to differences in pressure between the two panes glass, which are caused by extreme temperature fluctuations. It is crucial to keep blinds closed in hot weather and to avoid opening them up too much when the sun shines. This will prevent excessive heat from forming between the two panes.
To prevent cracks from forming on your double-glazed windows, make sure that the frames, particularly the hinges, locking mechanisms and handles, are secured. A quality double-glazed window should also be simple to open and close without sagging or sticking. Wiping the hinges and mechanism with a bit of oil may help, as can making adjustments to the locks and screws to ensure they're secured enough.
Be aware that a damaged glass window could pose a risk. If you notice shards of glass on the floor, or cracks in the double glazing, it is best to call an emergency glazier. It's better to replace the broken glass rather than attempt to repair it.
Likewise, any condensation in between the two panes of glass indicates that there is an issue with your seals and must be addressed immediately. A reputable glassmaker can drill into the sealed unit to inject or pump into drying agents (typically a desiccant) to remove any moisture. This is a quick and cost-effective solution. However, be aware that this is only a temporary fix and that you will need to replace your windows in the future in the future.
Condensation
Condensation can be a issue with older double glazing. Condensation occurs when moisture from the air is drawn into the gap between the glass panes and then condenses at night. This is a normal occurrence and not a sign of any issue with the glass or windows however it can be a source of frustration for homeowners since it prevents the double glazing from working as effectively as it should.
Add vents or trickle-vents to the frame to let air flow, eliminating any condensation in your home. The addition of this feature will also help to keep heat in the house and reduce energy bills in the long run.
A professional is often able to resolve the issue without having to replace the entire window. They'll drill tiny holes into the window to let out any moisture that has been trapped, and then apply an anti-fog coating.
Contact the company where you purchased your double glazing as soon as problems occur. It is important to contact the business you bought your double glazing from the moment you notice problems. This will enable them to send a technician out to inspect the situation and resolve any issues prior to them getting worse. It is also a good idea to keep all communications written down, such as an email or letter, as this will make it easier for you to dispute any claims that you may have in the future.
It is possible to fix some things yourself, but it is typically quicker and more efficient to hire an expert. This is especially the case for issues that require specialist equipment. Additionally professionals will usually provide a guarantee for their work that you will not necessarily get if you attempt to fix the double glazing yourself.
Draughts
Double-glazed windows are becoming increasingly popular as they help to increase energy efficiency, cut down on the amount of noise that can be heard inside the home, and protect furniture from ultraviolet light. They can also reduce condensation which is a frequent cause of mould. If they're not installed correctly, it's easy for air to leak through the gaps between the panes of glass, causing drafts.
In double-glazed windows two panes of glass are separated by a spacer bar and the gap is then filled with an insulating gas. The spacer bars typically contain a desiccant that assists in drawing moisture out of the gap, thus preventing internal condensation. However, as the desiccant loses its ability to remove moisture from the spacer bar, it's likely for condensation to develop between the glass panes. This is a typical issue with double glazing that's been poorly made. However it can be easily fixed by drilling holes in the glass or spacer bar, and then inserting a humidifier.
The space between the two panes of glass in a double-glazed window acts as an insulation by limiting the transfer of cold air from outside to inside your home. The insulation efficiency can be improved even further by using an inert low-conductivity gas such as argon to fill in the gaps.
Double-glazed windows are more expensive than single-glazed windows to put in however, they're usually worth the cost as they reduce heating and cooling bills, help to protect furniture from UV damage, and improve the value of your property. If glass window repair of having double glazed windows installed in your home, make sure to work with an experienced installer such as Thermawood. Their retrofit double-glazing system allows you to benefit of an IGU that is high-quality without having to remove your frame and the cladding.
Replacement
Double glazing offers many benefits for homeowners. It improves the efficiency of energy and also reduces noise. It also reduces the chance of draughts or the growth of mould on your window panes. They aren't indestructible, and sometimes problems can occur. It's important to remember that you can usually have most problems with double glazing repaired instead of replacing them, saving you the cost and hassle of having new windows fitted.
Double glazing owners are often required to repair a leaky seal. If this is the case, it's crucial to get in touch with an expert as soon as possible to set up an appointment for a window fitter to arrive and make the repairs required.
A window that isn't easy to shut or open can also be a problem. It could be due to heat or the mechanism is stiffening up over time. If this is the case, you can try cooling the mechanism down and lubricating the handles and hinges. Or, it could be that the frame has slightly dropped or sagged and requires to be adjusted.
The misting can also be fixed easily. The rubber seals that keep the two panes of glass together will wear away over time. This is typically caused by the frames moving slightly as they age and settling the special packaging material that keeps them in place. This then leads to one or both panes of your double glazing moving and breaking the seal.
Drilling into the affected glass is a way to remove moisture. This is a temporary solution and must be repeated. Installing trickle vents in your frames will be an ideal long-term solution. They let fresh air into the room, but prevent warm air from leaving.
