Repairing Double Glazed Windows
Double glazing can be an investment that will benefit your home. In time, it may create problems such as misting and condensation.
This can be caused by a variety of reasons, but it is typically due to the seals no more being airtight, causing 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, a hurled stone or even a cat's claw can cause a double-glazed window pane to break. In this case the cold or hot air can travel more easily between the two panes glass and your home becomes less well-insulated and increasing your energy bills. It's time to replace both windows if they are broken.
However, if one the panes is broken, but not completely shattered it could be possible to repair it. The first step is to remove the old pane from the frame wearing gloves and work glasses. Remove the loose putty from the edges that are broken of the glass using the painter's tool, which can be warmed by the help of a heat gun. Apply a piece or aluminum foil over the glass to keep them from cracking as the putty is removed.
When the frame is ready to accept the new pane of glass, grease the cutter with an inexpensive glass cutting tool -- available at most hardware stores -- using light oil such as WD-40. Cut the glass along the perimeter, approximately 1 inch from the edge. Then, put the glass inside the rabbets (the l-shaped grooves) in the window frame. Utilize the chiseled edge of the tool to remove any excess putty around the edge.
Press glazier's tips into the frame in intervals of six inches around the joint where the glass joins the frame. Then apply another cord of glazier's compound to the glass-frame joint and smooth it with the putty knife. If your windows are made from metal, you can paint the joints using a primer designed to prevent rust.
Cracks
Although it's not common double glazing cracks can occur suddenly - especially in older windows. The cause is often due to the difference in pressure between the two panes glass, caused by extreme temperature variations. It is essential to keep blinds shut in hot weather and to not open them too much when the sun shines. This will stop excessive heat from forming between the two panes.
The best way to avoid cracks in your double glazed windows is to ensure that the frames are secure, especially at the hinges, locking mechanisms, and handles. Double-glazed windows should be easy to open and shut, without sagging or sticking. Wiping the hinges and mechanisms with a little oil can aid, as can adjusting the screws and locks to make sure they're tight enough.
Remember that a cracked glass window could pose a risk. If you find shards on the floor or cracks in the double glazing, it's best to call an emergency glazing expert. It is better to replace the damaged glass rather than attempting to repair it.
Additionally, any condensation between the two glass panes tells you that there's an issue with the seals and should be fixed immediately. A reputable glazier will be able to cut into the seal and inject or pump dry agent, usually desiccant, into the window to get rid of any moisture. This is a simple and cost-effective solution. Be aware that this is an interim solution and you'll need to replace the windows in the future.
Condensation
Condensation is a typical issue with older double glazing. Condensation occurs when moisture from the air is drawn into the space between the glass panes, and then it condenses at night. This is a natural occurrence that does not signal any issues with the windows or glass. However it can be very frustrating to homeowners because it prevents the double glazing from operating effectively as it should.
The best solution is to add vents or trickle vents on the frame, allowing air to flow through, removing the possibility of condensation forming in your home. The addition of this feature will also aid in keeping heat inside the home and decrease energy costs in the long term.
Most times, a professional can fix the issue without having replace the entire window. They will make tiny holes in the window to expel any moisture that is trapped and then apply an anti-fog coating.
Contact the company through which you purchased your double glazing as soon as issues arise. This is to allow them to send out a technician to assess the situation and address any issues before they become worse. It is also a good idea to ensure that all communications are in writing, like an email or a letter, because this makes it easier to dispute any claims in the future.
It is possible to repair certain issues yourself, however it is generally faster and more efficient to work with a professional. This is especially applicable to any issues that require specialist tools. In addition professionals will usually provide a guarantee for their work that you won't necessarily receive when you attempt to fix the double glazing yourself.
Draughts
Double glazed windows are becoming more popular because they improve energy efficiency, reduce the amount of noise that can be heard inside the home, and protect furniture from UV light. They also help reduce condensation, which is a common cause of mould. If they are not properly installed, air can easily escape through the gaps in between the glass panes, leading to draughts.
In double-glazed windows the space between two panes of glass is filled with an insulating gas. The spacer bars usually contain a desiccant, which helps to draw moisture from the gap, which prevents the formation of condensation inside. However, when the desiccant ceases to function to eliminate moisture from the spacer bar, it is possible for condensation to form between the panes of glass. This is a problem that occurs frequently with double glazing that is not properly made, but it can be fixed by drilling holes in the glass or spacer, and after that, putting in the dehumidifier.
The space between the two panes of glass in a double glazed window acts as an insulator by limiting the transfer of cold air from outside to inside your home. The insulation efficiency is enhanced by using an inert low-conductivity gas, such as argon to fill in the gaps.
Double glazed windows are more expensive than single-glazed windows for installation however, they're usually worth the investment since they can reduce cooling and heating costs, protect furnishings from UV damage, and boost the value of your home. If you're considering installing double-glazed windows into your home, consult an experienced installer such as Thermawood. Their retrofit double-glazing system allows you to benefit of an IGU that is high-quality without having to remove your frame and the cladding.
Replacement
Double glazing offers numerous benefits to homeowners. it improves energy efficiency, reduces noise and condensation. It also helps reduce the risk of draughts and the growth of mould on window panes. However, they aren't indestructible and problems do sometimes occur. It's important to keep in mind that you can repair most issues with double glazing repaired instead of replacing them which will save you the expense and hassle of having new windows installed.
One of the most common problems that homeowners with double glazing encounter is having to fix a leaky window seal. If this is the case, it is important to speak with a professional in order to arrange for an installer to come out and make the necessary repairs.
Another issue is when windows become difficult to open or close. This could be due to heat, or perhaps because the mechanism has become stiffer over time. Try cooling the mechanism down and lubricating hinges or handles if this is the problem. Alternatively, it may be that the frame has fallen or sagged, and requires to be aligned.
Misting is also something that can be fixed easily. The seals made of rubber that hold the two glass panes together wear out over time. This is often caused by the frames moving little as they age, and the specific packaging material that keeps them in place, which results in one or both panes of your double glazing shifting and breaking the seal.
Misting can be treated by door repair drilling holes in the glass affected and then removing the moisture from within. This is only temporary solution, and will likely require repeated. A better long-term fix is to put trickle vents into your frames, which allows fresh air to enter but won't let any warm air escape.
