15 Terms Everybody Who Works In Repair Double Glazing Industry Should Know
How to Repair Double Glazed Windows
Many homes with double glazing are plagued by problems like condensation, a decrease in the quality of insulation and windows that are difficult to open. These issues are usually caused by problems with the hinges or handles.
Repairing these windows is possible with a few easy steps.
Cracked Panes
A double-paned window that is damaged is a serious problem that must be addressed immediately. Triple- and double-pane windows are insulated with gases that ensure warm air is kept in during winter and cold air out. Therefore, when one of the panes cracks this gas escapes and your home is less insulated. Cracks can also become worse as time passes. Fixing them now will prevent a larger problem in the future.
The most important thing to do when a crack appears is to determine the cause of it. It's possible that an impact or structural issue led to the crack. In this instance it is crucial to check your other windows for damage and determine the next steps.
It is also important to look at the surrounding area to determine if there are any other problems that could be contributing. If your windows are situated near walls or doors the stress resulting from changes in temperature could cause cracking.
There are several ways to repair a crack depending on the source. For instance, if the crack was caused by an impact, you might be able to get away by replacing only the broken glass. It is possible to replace the whole window frame. This is a more complex procedure, and requires the assistance of an expert.
If you've noticed cracks in your glass that did not cause the frame to move then it's usually simple to apply adhesive between the broken panes. This fixes the fracture and protects your window from future problems, so it's certainly worth a try in this instance.
Another option that is fairly easy is to cover the crack with clear tape. It's not the prettiest solution, but it prevents drafts and bugs getting into your home. An alternative is a glass repair film made to be easily applied and offers more durable protection. This is available from many double glazing companies and is worth the investment to secure your windows.
Condensation Build-Up
Condensation build-up in between the panes of double-glazing is one of the most frequent reasons homeowners need to repair their windows. This is because it usually indicates that the seal between the panes of glass has failed, allowing water vapour to get in. This water vapour can cause condensation and other issues that may need the window replaced.
Double glazing is more effective in reducing condensation than single pane windows as it has an air space between the glass that is either filled with air or gas that is not toxic. The space is separated from the frame by a spacer bar, which acts as an insulation to stop heat loss. In a lot of cases, the spacer bar is filled with a silica gel, which is extremely effective in taking in moisture and preventing it from leaking between the panes of glass.
It is therefore important to regularly wipe down and clean your windows. This will reduce the amount of moisture that accumulates and allow it to evaporate. Ventilation fans and opening windows can help to remove moisture.
Another way to combat condensation is to install a dehumidifier in your home. They can be purchased for around PS60-PS150 and are a wise investment that will not only reduce condensation but prevent mould growth within your home, too.
Condensation can happen between the glass panes of your double glazing because the outside air is cooler than the interior pane. This causes the surface of the glass to cool and create condensation. It could also happen when you have changes in temperature, such as turning on the heating or cooling your home.
Condensation is also an indication of poor double glazing, as older units were made with rubber strips instead of the modern silicone variety. window security can become damaged over time. In some cases it is possible to have your seals replaced but it's important to remember that this is only the short-term solution as the window will eventually degrade in a different area, which means you'll have to replace it eventually.
Stained Glass
If you have a problem with a double glazed window handle or lock it is usually possible to fix it rather than having to replace the entire glass pane. However, this isn't necessarily a DIY job since specific tools are required to ensure the repair is done in a way that will not affect the seal or the function of the window.
Many double glazing owners complain that their windows or doors are difficult to open. This is usually due to some slight warping of the frame or hinges but can be caused by problems with the sealing. In some cases the issue could be more serious and it is advisable to talk to a professional regarding the options available.
Another frequent complaint is the formation of condensation between glass panes. This could be a sign of a leaky seal that isn't holding the gases that insulate between the glass panes. It is also an easy fix and the gas that insulates can be restored with a special adhesive to seal the gap between the panes.
Place the damaged window on an even surface. Remove the black sealant to expose the silver spacer bar and cut into it with a sharp blade, making sure to stay below the glass's bottom and the silver spacer bar. After you have separated the two pieces, place the top glass pane on the work surface. It is recommended to use gloves for this step. Once again thoroughly clean both the glazed side that faces into the frame and the spacer frame taking care to remove any marks or smears since they could affect the seal when the window is re-assembled. Lastly, position the new spacer bar on the glass pane and apply adhesive on its edges to ensure it bonds to the glass and the silver spacer frame. Let it set before reassembling. This is usually a job for two as it can be difficult to get everything lined up.
Gasket Seals
While double glazing is highly durable and designed to last for many years to come, there are still issues that can arise occasionally. From draughts to problems with closing or opening it is crucial to address any problems promptly to avoid them becoming worse.
One of the most common issues reported by double-glazed owners is condensation forming between the two glass panes. This is due to the failure of the desiccant, which absorbs moisture in the air in the insulated gap. When the desiccant fails the condensation will form within minutes and create a dark line on the window.
Another issue can arise when the gasket seal fails to prevent water and other contaminants from leaking into the insulated gap. This can cause leaks around the edges of the frame, and could also cause damage to the surface of the double glazed unit itself. Contact your installer immediately if you spot any indications that your double-glazed units are leaky.
Many companies offer a guarantee on their products, and they usually include a guarantee period of 10 or 20 years, and some even offer lifetime guarantees. It is essential to review the specifics of your guarantee to see what it covers and the date it expires.
It might be worthwhile trying to solve any hardware issues yourself prior to calling your double glazing provider to request repairs. For instance, you can try cooling the mechanism or lubricating it to see if this fixes the problem. Alternatively, you can try taking the handle off or the window handle and cleaning it prior to putting it back in place.
Check with your local council to find out whether they have any grants to assist you in the replacement or repair of your double-glazed windows. There are numerous ways to apply and some areas will require a particular form of application or evidence of eligibility, so it is always worth checking with your local authority prior to deciding on how to proceed.
