Repairing Double Glazed Windows
Repairing double glazed windows can be a challenge to tackle and you should always seek out an expert. This is because certain tools are required, and it is generally more time-consuming than fixing it yourself.
Condensation or mist in double-glazed windows indicates that the seals have failed, and moisture has built up between the two glass panes. It is possible to fix this without having to replace the entire window.
Seals
Double glazing is designed to increase energy efficiency by limiting the transfer of heat between the glass panes. If the window seal is damaged, this could affect the efficiency and increase the cost of electricity and gas. It's important to keep your windows and doors well-maintained to ensure the integrity of the seal which is your primary defense against increasing energy costs.
The most common cause of window seal failure is condensation. Condensation can happen when the temperature of the window glass drops during the night. In time, this may cause the seal to wear out and cause a fogging or draught inside your home. This is a normal occurrence and does not mean that there is an issue with the double glazing installation. However, window defogging can be employed to eliminate the condensation.
The type of glass that you choose will also influence the performance of the windows. Certain glass is tinted or annealed, which increases its energy efficiency. It is also possible to add an inert gas to the space between the glass to improve insulation and enhance acoustic performance.
Gases can be used to fill the gap between the glass panes of double-glazed windows to increase insulation and acoustic properties. Typically, argon is used, as it has low conductivity, and can limit the transmission of medium- and high-frequency sounds, like traffic noise and voices.
If your double glazed windows aren't performing as well as they once did, you might want to consider an IGU replacement. These windows are costly, but offer many advantages and are energy efficient.
You'll save money on energy bills, and the increased soundproofing of the double-glazed window will help prevent damage to furniture, carpet, walls, artwork, and other belongings in your home. Double-glazed windows are more environmentally friendly than single-paned windows that were previously used. They can reduce the amount of waste that is disposed of in landfills, and greenhouse emissions. Furthermore, they increase comfort by reducing the amount of cold air that enters your home.
Glass
It is possible to fix misty glass in double-glazed windows without having to replace the entire window. A misty window is caused when the seals between the two glass panes fail. When this occurs the gap is usually filled with hot air that removes any moisture that remains and forms a new, clear seal. This can help prevent condensation, draughts, or leaks.
However, if the glass itself cracks or damaged, it's going to need to be replaced with a brand new pane of glass. This can be done relatively cheaply using glass repair kits that is available at a variety of DIY stores. A glazing professional can repair your broken glass with an identical unit or upgrade your double-glazed windows to include the most recent energy-saving technologies like argon-filled panes and thermo spacer bars.
Double-glazed windows may mist, but it's also possible that they are difficult to open and close. The frame may expand or contract due to variations in temperature throughout the day. Oiling the handles, hinges and the places where they touch the frame is often the best solution to this problem.
If your double-glazed windows are sagging or falling, it may be possible to put them back together using the same adhesive that is used to fix misted windows. Again, this is a short-term fix and will not solve the issue of having to constantly struggle with your doors and windows to shut and open them.
Each window repair contractor will charge different rates for their services. It is therefore important to contact multiple contractors until you've received price estimates that are comparable. When comparing prices, remember to factor in any additional costs that could be incurred like material, labor and VAT. Also, always be repairing double glazing windows of selecting the lowest quote because it may not mean the best quality work.
Frames
The frames of double-glazed windows are made out of aluminum, wood or unplasticised polyvinylchloride (uPVC). The type of frame plays an significant role in the energy efficiency of your home. The frames reduce the U-factor by up to 30%. Double glazing offers additional insulation, and the seals on the window casement prevent air from getting out during colder seasons.
Aluminium frames are extremely light and sturdy. They come in different finishes, including powder-coating or anodizing. They are energy efficient, particularly when they are fitted with the "thermal break". The thermal break is an insulating plastic strip that is separated from the aluminum and stops heat from escaping through the window. Even high-performance frames be unable to keep their insulation when exposed to direct sun for extended periods of time.
uPVC is an increasingly popular material for framing, and it's easy to see why. It is durable, maintenance-free and will not rust or warp. uPVC also has excellent insulation qualities and is air and water impervious. uPVC is also BPA-free and recyclable.
Timber frames may be more expensive than aluminium and uPVC but they have an attractive natural appearance that adds to the value of your home. They are also a great insulator and provide a sound barrier.
Another benefit of wooden frames is that they can be painted or stained to match the decor of your home. Wooden windows also limit the amount of harmful UV rays that could enter your home. The rays can cause damage to carpets, damage furniture and paints, as well as age paints and wallpaper. Double-glazed windows block UV Rays and keep your home looking brand new for longer.
The space between the two panes of glass in a double-glazed window acts as an insulation and can be further improved by the addition of the gas argon. It has low conductivity properties that improve the windows' insulating and sound performance. It's important that the gap is sealed properly and that the spacer is stocked with an aqueous dispersant, since condensation from moisture can form between the panes.
Hardware
Double glazing isn't just an energy-efficient option, but it's also a great security option. Double pane windows are resistant to breaking and require a lot more noise to do it. This makes it harder for burglars to escape or avoid being caught. Double-glazed windows are typically fitted with tougher glass, and frames are made from more durable materials such as aluminium or timber. These are strong materials that last for an extended time, particularly when they've been maintained properly.
The life expectancy of a double glazed window is determined by a variety of factors. They should be well-maintained and cleaned regularly to prevent dirt or water from entering and causing corrosion, rust and rot. The frames must be inspected for damage, including cracks and dents, and painted regularly. It is also essential to take care of the locks. If they are damaged, it will be easy for burglars to gain entry through the window.
Many companies offer a warranty for double glazed windows, typically around 10-plus years for the frame and glass, with a few providing longer or even lifetime warranties. Review the conditions and terms to make sure that you are covered in the event of an issue.
Double-glazed windows are vulnerable to drafts. This can result in a reduction in thermal efficiency and higher energy bills. This could be caused by a variety of reasons including poor ventilation, lack proper maintenance, and faulty seals. Candles placed near the window will allow you to feel the breeze passing through.
To prevent drafts, you can try caulking or weatherstripping to fill any gaps around windows. A professional glazier will be able to provide you with suggestions on how to repair your windows if you are unsure.
