Repairing Double Glazed Windows
Double glazing is an investment that will benefit your home. As time passes, it will develop problems like misting and condensation.
This could be due to a number of causes, but usually due to the seals no longer being air-tight, causing loss of the insulating gas that sits between the glass panes. It is beneficial to know how to repair double glazing.
Broken Panes
A loose ball from a lawnmower or a stone that has been thrown around even a cat's claw can cause a double-glazed glass pane to shatter. This allows cold or heat to flow more easily between the two panes of glass, reducing the insulation and resulting in higher the cost of energy. upvc window repairs to replace both windows if they are damaged.
However, if one of the panes has been broken, but not completely shattered It might be possible to repair it. First, remove the old glass from the frame wearing safety glasses and gloves. Remove the loose putty from the broken edges of the glass with the painter's tool, which you can warm with the aid of a heat gun. Use aluminum foil to shield the glass from cracking as the putty is being removed.
Once the frame is prepared to accept a replacement pane, lubricate a cheap glass-cutting tool (available in most hardware stores) with WD-40 or another light oil. Score around the perimeter of the glass, about 1 inch from the edge. Then, put the glass inside the rabbets (the grooves that resemble ls) in the window frame. Utilize the chiseled edge of the tool to get rid of any putty that is accumulated around the edge.
Apply glazier's tips to the frame in intervals of six inches around the joint where the glass meets the frame. Apply another cord of glaziers compound to frame-glass joints and smooth them with a putty blade. If your windows are made from metal, you can paint the joints with a primer that is designed to keep rust from happening.
Cracks
Although rare the possibility of a cracking in your double glazing could occur - particularly in older windows. The reason is usually due to the difference in pressure between the two panes of glass, caused by extreme temperature fluctuations. This is why it's essential to keep your blinds closed in hot weather and to not open them too much when the sun is shining - this will prevent excessive heat from building up between the two panes of glass.
The best way to prevent cracks in your double glazed windows is to make sure that the frames are secure, particularly on the hinges, locking mechanisms and handles. Double glazed windows should be simple to open and close, without sagging or sticking. Wiping the hinges or mechanisms with a little oil can help, as can adjusting the locks and screws to ensure they're secure enough.
It's important to remember that a window that is cracked is not just ugly and can also be risky. If you find cracks in your double glazing and you can see loose shards of glass on the floor, you should call an emergency glazier immediately as it's probably better to replace the damaged glass entirely rather than fixing it.
Additionally, any condensation between the two glass panes suggests that there's an issue with your seals and should be fixed immediately. A reputable glassmaker can drill into the sealed unit to inject or pump in drying agents (typically desiccant) to remove any moisture. This is a fast, cheap and effective solution to this problem. But be aware that this is a temporary fix, and you will have to replace your windows in the near term.
Condensation
Condensation is a concern with older double glazing. It happens when moisture from the air is pushed into the space between the panes, and then condenses during the night. This is a natural phenomenon that doesn't indicate any problem with the glass or windows. However it can be very frustrating to homeowners as it hinders the double glazing from performing in the way it should.
Install vents or trickle-vents on the frame to allow air to flow, preventing condensation that may be present in your home. This will also help keep the temperature in your home and lower energy bills over time.
Most times, a professional can fix the problem without having to replace the entire window. They will make tiny holes in the window to let out any moisture that has been trapped, and then apply an anti-fog coating.
Contact the company from which you purchased your double glazing as soon as any issues occur. It is crucial to contact the business you purchased your double glazing from the moment you start experiencing problems. This will allow them to send a technician out to assess the situation and address any issues prior to them getting worse. It is also a good idea to have all communication in writing, such as an email or letter since this will make it easier to contest any claims that you may have in the future.
While it is possible to do some repairs yourself, it's normally much faster and more efficient to hire a professional to complete the task. This is especially applicable to issues that require specialized equipment. Professionals will also provide an assurance on their work, which you might not receive if you try to repair the double glazing yourself.
Draughts
Double-glazed windows are becoming increasingly popular because they increase energy efficiency, cut down on the amount of noise that is heard inside the home and protect furniture from damage caused by ultraviolet light. They can also help to minimize condensation, which is a typical cause of mould. However, if they're not installed correctly, it's easy for air to escape through the gaps between the glass panes, causing draughts.
In double-glazed windows two glass panes 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 away from the gap, preventing internal condensation. However, as the desiccant ceases to function to eliminate moisture from the spacer bar, it's likely for condensation to form between the glass panes. This is a common problem with double glazing that has been badly made. However it can be fixed by drilling holes in the glass or spacer bar and inserting an humidifier.
The space between two panes in a double-glazed window serves as an insulation, preventing cold air from transferring into your home. The insulating performance can be improved even further by using an inert, low-conductivity gas, such as argon to fill the gap.
Double glazed windows are more expensive than single-glazed windows for installation however they're generally worth the cost as they can reduce cooling and heating bills, help to protect furnishings from UV damage, and improve the value of your home. If you are considering installing double-glazed windows in your home, consult an experienced installer like Thermawood. Their retrofit double glazing system lets you to take advantage of a premium IGU without having to remove your frame and cladding.
Replacement
Double glazing has many advantages for homeowners. It improves the efficiency of energy and also reduces noise. It can also help to reduce the risk of draughts and mould forming on windows. But, they're not impervious to damage and issues can occur. It's worth remembering that you can usually get most double glazing faults repaired instead of replacing them, saving you the cost and disruption of having new windows installed.
Double glazing owners are often required to fix a leaking seal. If this is the situation it is essential to get in touch with a professional to arrange for an installer to visit and make the necessary repairs.
A window that isn't easy to shut or open can also be a problem. This could be due to heat, or because the mechanism has become stiffer over time. Try cooling the mechanism down and lubricating hinges or handles in the event that this is the cause. Or, it could be that the frame has slightly dropped or sagged and needs to be aligned.
Misting is also something which can be easily fixed. The seals made of rubber that hold the two panes of glass together will wear away over time. This is usually caused by the frames moving slightly as they age and the special packaging material that keeps them in place. This can result in one or both panes of your double glazing moving and breaking the seal.
Misting can be corrected by drilling holes into the affected glass and removing the moisture inside. This is a temporary fix and will need to be repeated. A better long-term fix is to add trickle vents in your frames, which will allow fresh air to circulate but won't let any warm air escape.
