Repairing Double Glazed Windows
Double glazed window repair can be a challenge and you should seek the advice of an expert. It is more time-consuming and requires specific tools to complete the task yourself.
Double-glazed windows that appear misty or condensed indicate that the seals are not working and moisture has built up between the two panes. Fortunately, this can be repaired without having to replace the entire window.
Seals
Double glazing is designed for energy efficiency by limiting transfer of heat between glass panes. However, if the window seal is damaged, it will affect the effectiveness of this insulating feature, resulting in more expensive gas and electricity bills. Keep your doors and windows in good order to ensure the seal integrity which is the first line of defense against rising energy costs.
Condensation is one of the main causes of failures in window seals. When the glass's temperature decreases at night, moisture from dew or rain can condense against it. In time, this may cause the seal to break and cause a fogging draught inside your home. This is a common occurrence and does not mean that there is an issue with the double glazing installation. However window defogging is 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 to increase its efficiency in energy use. It's also possible to add an inert gas into the space between the glass in order to improve insulation and enhance acoustic performance.
Gases can be used to fill the space between the glass panes in double-glazed windows to improve insulation and acoustic qualities. Argon is commonly used as it has a low conductivity, and is able to reduce the transmission high- and medium-frequency sounds, such as voices and road noise.
If your double glazed windows aren't performing as well as they used to it's time to consider an IGU replacement. These windows are costly however they provide many advantages and are extremely energy efficient.
You'll save money on energy bills, and the enhanced soundproofing of the double-glazed window will help prevent damage to furniture, carpet, walls, artwork, and other belongings in your home. Double-glazed windows also have a much less impact on the environment than old single-pane windows. They can reduce the amount of waste that is disposed of in landfills and greenhouse emissions. They also increase the comfort in your home by reducing the amount of cold air that gets in.
Glass
It is possible to repair misted glass in double-glazed windows without having to replace the entire window. When the seals between two panes of the glass fail, a misty window occurs. In this case, the gap is typically filled with hot air which draws out any remaining moisture and forms a new clear seal. This is often helpful with condensation problems as well as leaks and draughts.
If the glass is chipped or damaged, it needs to be replaced by a new piece of glass. repair double glazing can be done relatively cheaply using a glass repair kit that is available at a variety of DIY stores. Alternatively, a glazing contractor can replace the broken glass with a perfectly matching unit, and even upgrade your existing double-glazed windows to incorporate the latest energy saving advances such as argon gas filled panes and thermal bars for spacers.
Double-glazed windows may mist, but it is also possible that they are difficult to open and close. This can be caused by the fluctuation in temperature throughout the day and during the year which causes the frame to shrink or expand in a slight way. Oiling the handles, hinges and the places where they meet the frame is often an effective solution to this issue.
It is possible for you to re-stuff your double-glazed windows with the same adhesive used to fix misted glass. Again, this is only a temporary fix that will not resolve the problem of having to constantly struggle with your doors and windows to open and shut them.
Each window repair contractor will charge a different rate for their services. It is therefore important to speak with multiple contractors until you've received quotes that are comparable. When comparing prices, be sure to take into account any additional charges that might be incurred such as extra labor, materials and VAT. Be careful when selecting the lowest price as it may not mean the best workmanship.
Frames
The frames of double-glazed windows can be made out of aluminum, wood or unplasticised polyvinylchloride (uPVC). The type of frame is a key element in the energy efficiency of your home. The frames function as an insulation and can reduce the U-factor of your windows by as much as 30 percent. The double glazing itself provides additional insulation, and the seals around the window casement help to keep the air from entering your home during colder seasons.
Aluminium frames are strong and light, and they are available in a variety of finishes such as powder-coating and anodising. They are extremely energy efficient, especially when they're fitted with a thermal break'. The thermal break is a thin strip of insulating material that separates the aluminium and blocks heat from flowing through the window. Even high-performance frames may be unable to keep their insulation when exposed to direct sun for long periods of time.
uPVC is a very popular material for framing, and it's not hard to see the reason. It's strong, durable, maintenance-free and won't rust or warp. In addition to this, uPVC is water and air tight and offers excellent insulating properties. uPVC also is BPA-free, recyclable and has excellent insulating properties.
Timber frames are more expensive than aluminium or uPVC, but they offer a natural look that enhances the value of your home. They are also a great insulation and sound barrier.
Another benefit of wooden frames is that they can be painted or stained to match the decor of your home. They also reduce the amount of harmful UV rays which can be absorbed by your home. These rays can harm furniture, fade carpets and paints, as well as age paints and wallpaper. Double-glazed windows are able to block out UV rays and help to keep your home's interior looking fresh for a longer period of time.
The space between the two panes of glass in a double glazed window acts as an insulator and is further improved by the addition of argon gas. This gas has a low conductivity and enhances the insulation properties of a window. It's important that the gap is properly sealed 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 also a fantastic security option. Double windows are harder to break than single panes, and a burglar will need to make lots of noise in order to successfully enter and draw attention to them and making it difficult for them to escape or avoid capture. Double-glazed windows often have tougher glass and frames constructed from stronger materials like aluminium or wood. These materials are durable and will last for a long period of time if they have been maintained properly.
The life expectancy of double-glazed windows is dependent on a variety of aspects. It is important to maintain their cleanliness and keep them clean to prevent dirt and water from entering the frame and causing rust corrosion and decay. The frames should be regularly painted and inspected for signs of damage, such as cracks or scratches. It's also important to check at the locks, as in the event that they're damaged, it can be easy for burglars to get in through windows.
Many companies offer a warranty for double-glazed windows. typically around 10-plus years for the frame and glass, with some offering longer or even life-long warranties. It's essential to review the terms and conditions thoroughly to ensure you're covered in the event of any issues.
One of the most common issues with double-glazed windows is the development of drafts, which can decrease the efficiency of heating and result in higher energy costs. This can be due to a variety of reasons, including inadequate ventilation, improper maintenance, and defective seals. A candle placed near the window allows you to feel the breeze passing through.
You can close any gaps around windows using weatherstripping and caulking. If you're unsure what to do or how to proceed, a professional glazier will provide advice on the best method to fix your windows.
