Repairing Double Glazed Windows
Double glazing can be an excellent investment for your home. However, with time, it may develop issues such as misting or condensation.
It could be caused by a variety of causes, but usually due to the seals not enough air tight, which can lead to a loss in the gas that acts as an insulation between the glass panes. It is helpful to understand how to fix double glazing.
Broken Panes
A loose ball from the lawnmower or a stone thrown at it even a cat's claw can cause a double-glazed window pane to break. This allows heat or cold to move more easily between two panes of the glass, reducing the insulation and resulting in higher energy bills. If both of the windows are cracked then it's time to contact a professional to replace the windows.
If one of the panes has cracked but not completely shattered it is still possible to repair. The first step is to take the old pane from the frame wearing gloves and work glasses. Remove the loose putty from the broken edges of the glass with the painter's tool, which can be warmed by the help of a heat gun. Use aluminum foil to protect adjacent panes from cracking while the putty is being removed.
Once the frame is ready for a new pane, make sure to lubricate the cutter using a cheap glass cutting tool -- found in many hardware stores -- using lightweight oil like WD-40. Cut the glass along the perimeter, about 1 inch from the edge. Then, gently slide repairing upvc windows to fit into the rabbets or grooves that are shaped like an l, in the window frame where it sits. Use the chiseled edges of the tool to take away any excess glue around the edges.
Press glazier's tips into the frame at intervals of six inches around the joint where the glass joins the frame. Then, apply a second cord of glazier's compound to the glass-frame joint and smooth it using the putty knife. If windows are made of metal, you can paint the joints using a primer designed to prevent rust.
Cracks
Although it is not common the possibility of a cracking in your double glazing can occur, particularly in older windows. The reason is usually due to pressure differences between the two panes of glass, which are caused by extreme temperature changes. It is important to keep blinds closed during hot weather, and to be careful not to open the blinds too often when the sun is shining. This will stop excessive heat from building between the two panes.
The best way to avoid cracks in your double glazed windows is to ensure the frames are secure, especially at the hinges, locking mechanisms and handles. A well-constructed 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 aid, as can changing the locks and screws to ensure they're secure enough.
Remember that a cracked glass window could be dangerous. If you notice a crack in your double glazing and you can see shards of glass that are loose on the floor, you should call an emergency glazier as it's probably best to replace the broken glass entirely instead of fixing it.
If you notice condensation between the two panes, this is a sign that your seals are not working properly and need to be replaced immediately. A professional glazier with a good reputation will be able to drill into the sealed unit and inject or pump dry agent, usually desiccant, into the window to get rid of any moisture. This is a quick and cheap solution. Be aware that this is an interim solution and you'll need to replace the windows in the near future.
Condensation
Condensation is a typical issue with older double glazing. It occurs when the moisture from the air is pulled into the gap between the panes and then it condenses at night. This is a normal occurrence that doesn't indicate any issues with the windows or glass. However it can be very frustrating for homeowners since it stops the double glazing from operating in the way it should.
Add vents or trickle-vents the frame to allow air to flow, removing any condensation that may be present in your home. The addition of this feature will also aid in keeping heat inside the house and help reduce energy costs in the long term.
Most times, a professional can fix the issue without having replace the entire window. They will drill tiny holes into the window to let out any moisture that has been trapped and then apply an antifog coating.
Contact the company where you purchased your double glazing as soon as problems arise. This is to allow them to send a technician out to assess the situation and address any issues before they become worse. It is recommended for all communication to be in writing. This can be done through mail or letters.
While it is possible to do some repairs yourself, it is normally much faster and more efficient to hire a professional to do this. This is particularly applicable to any issues that require the use of specialist tools. A professional can also provide an assurance on their work, which you may not receive if you try to fix the double glazing by yourself.
Draughts
Double-glazed windows are becoming increasingly popular as they help to increase energy efficiency, decrease the amount of noise heard inside the home, and prevent damage to furnishings from UV light. They also help reduce condensation which is a typical reason for the growth of mould. If they're installed correctly, it is easy for air to leak through the gaps between the panes of glass and cause the draughts.
In double-glazed windows two glass panes are separated by a spacer bar. the gap is then filled with an insulating gas. The spacer bars typically contain a desiccant, which assists in drawing moisture out of the gap, which prevents internal condensation. The desiccant's capacity to remove moisture from spacer bars decreases, condensation can form between the glass panes. This is a common problem with double glazing that's been poorly constructed. However it can be fixed by drilling holes in the glass or spacer bar and putting in a humidifier.
The space between two panes in a double-glazed window acts as an insulator, stopping cold air from entering your home. Filling the gap with an inert gas, such as argon, can improve the insulating properties even more.
Double glazed windows are more costly than single-glazed windows to install, but they're often well worth the investment since they lower cooling and heating costs, protect furnishings from UV damage and can improve the value of your home. If you're thinking of installing double-glazed windows in your home, be sure you choose a highly-experienced installer like Thermawood. Their retrofit double-glazing technology allows you to reap the benefits of a high-quality IGU without removing the frames and cladding.
Replacement
Double glazing can bring many advantages for homeowners. It increases the efficiency of your energy use and reduces noise. It also reduces the chance of draughts or the growth of mould on the window panes. They aren't impervious to damage and, in some cases, problems may occur. It's important to keep in mind that you can typically have most problems with double glazing repaired rather than replaced and save yourself the expense and disruption of having new windows fitted.
Double glazing owners often have to repair a leaky seal. If this is the case it is crucial to contact a professional to schedule a window installer to come out and make the necessary repairs.
Another issue occurs when windows become difficult to open or close. This could be due heat or because the mechanism has become stiff as time passes. If this is the case, you can try cooling the mechanism down and lubricating hinges and handles. It could also be that the frame has slightly dropped or sagged and requires to be adjusted.
Misting is another issue which can be easily fixed. The seals made of rubber that hold the two panes of glass together wear out over time. This is usually caused by the frames shifting in a slight manner as they age and compacting the particular packaging material that keeps them in place. This then leads to one or both panes of your double glazing moving and breaking the all-important seal.
Drilling into the glass is a way to eliminate moisture. This is a temporary solution and will need to be repeated. A better long-term fix is to put trickle vents inside your frames, which will allow fresh air to circulate but will not let any warm air escape.
