Double glazing is an excellent investment for your home. As time passes, it will cause problems such as misting or condensation.

The cause can be due to many reasons, but it's typically due to the seals not being airtight. This leads to a loss of the gases that are used to insulate and are positioned between the glass panes. It can be helpful to understand how to fix double glazing.

Broken Panes

A accidental ball from a lawnmower, a hurled stone or even a claw of a cat could cause a double-glazed window pane to break. This allows cold or heat to move more easily between the two panes of the glass, reducing the insulation and resulting in higher energy bills. If both windows are shattered and you're in need of a professional to replace the windows.

If one of the panes has damaged but not completely broken, it is still be repairable. The first step is to remove the old pane from the frame, wearing gloves and work glasses. Remove the loose putty from the cracked edges of the glass with the painter's tool, which you can warm with the help of a heat gun. Use aluminum foil to protect the glass from cracking as the putty is being removed.

After the frame has been prepared to accept a replacement pane use a glass-cutting tool that is cheap to lubricate (available in the majority of hardware stores) with WD-40 or a similar lightweight oil. Cut the glass along the perimeter, about one inch from the edge. Then, place the glass in the rabbets (the grooves with an l) in the window frame. Use the chiseled edges of the tool to remove any putty that is accumulated around the edges.

After the new pane is installed, press the glazier's points into your frame every six inches around the edge where it joins the glass. Apply another cord of glaziers compound to the frame-glass joints and smooth with a putty blade. If your windows are made from metal, you can paint the joints with an adhesive designed to prevent rust.

Cracks

Although it's rare, double glazing cracks can occur suddenly - especially in older windows. The reason is usually due to pressure differences between the two panes glass, which are caused by extreme temperature variations. It is essential to keep blinds closed in hot weather, and to avoid opening them too much when the sun shines. This will stop excessive heat from building between the two panes.

The best way to avoid cracks in your double glazed windows is to make sure that the frames are secure, especially on the hinges, locking mechanisms and handles. Double-glazed windows must be easy to shut and open and repairing door should not sag or stick. Wiping the hinges and mechanism with a small amount of oil could assist, as could making adjustments to the screws and locks to make sure they're tight enough.

Remember that a cracked glass window can be dangerous. If you have a crack in your double glazing and you can see loose shards of glass on the floor, contact an emergency glazier immediately as it's likely to be better to replace the damaged glass completely rather than repair it.

If you see condensation between the two panes of glass, this is a sign that your seals aren't functioning correctly and must be repaired immediately. A reputable glazier could drill into the sealed unit to inject or pump into drying agents (typically a desiccant) to remove any moisture. This is a simple and cost-effective solution. Be aware that this is an interim solution and you'll need to replace your windows in the future.

Condensation

Condensation is a common problem with older double glazing. Condensation happens when moisture in the air is drawn into the space between the glass panes, and then it condenses at night. This is a natural phenomenon that doesn't indicate any problem with the glass or windows. However, it can be frustrating for homeowners since it stops the double glazing from working effectively as it should.

Add vents or trickle-vents to the frame to let air flow, removing any condensation in your home. The addition of this feature will also help to keep heat in the home and decrease energy bills in the long term.

Often a professional can doors repair the issue without having to replace the entire window. They'll drill a tiny holes into the window to let any moisture trapped and then apply an antifog coating.

Contact the company from which you purchased your double glazing as soon as problems occur. This is to ensure that they send out a technician to assess the situation and address any issues prior to them getting worse. It is recommended that all communications be written. This can be done through email or letter.

It is possible to fix some things yourself, but it is generally faster and more efficient to employ an expert. This is particularly applicable to any issues that require specialist tools. In addition an expert will usually provide a guarantee for their work that you won't necessarily receive if you try and fix the double glazing yourself.

Draughts

Double glazed windows are becoming increasingly popular as they help to improve energy efficiency, reduce the amount of noise heard inside the home and prevent damage to furnishings from ultraviolet light. They also help reduce condensation which is a frequent cause of mould. If they are not properly installed, air can easily get through the gaps in between the glass panes and cause drafts.

In double-glazed windows two glass panes are separated by a spacer bar. the gap is then filled with insulating gas. The spacer bar usually contains an ingredient called desiccant which helps draw moisture out of the gap, preventing interior condensation. As the desiccant's ability to eliminate moisture from spacer bars diminishes, condensation can form between the glass panes. This is a typical issue when double glazing is poorly made however it is easily fixed by drilling holes in the glass or spacer and after that, putting in a dehumidifier.

The space between the two panes of glass in a double glazed window acts as an insulation by limiting the flow of cold air from outside into your home. The insulation efficiency is enhanced by using an inert, low-conductivity gas like argon to fill the gap.

Double-glazed windows cost more to install than single-glazed ones but are usually worth the cost as they reduce your heating and cooling costs, protect your furnishings from UV damage, and also increase the value of your home. If you're thinking of installing double-glazed windows repairs into your home, work with an experienced installer like Thermawood. Their retrofit double-glazing system allows you to enjoy all the benefits of an IGU without removing the frame and cladding.

Replacement

Double glazing has many advantages for homeowners. It increases the efficiency of energy and also reduces noise. It also reduces the chance of draughts or mould building up on your window panes. However, they're not indestructible and there are times when problems can arise. It's important to remember that you can usually repair double glazed windows most issues with double glazing repaired, rather than replaced, saving you the cost and disruption of having new windows installed.

One of the most common issues that people who own double glazing experience is having to fix a leaky window seal. If this is the case, it is important to contact a professional to arrange for a window installer to come out and complete the repairs needed.

A window that is difficult to open or shut can be a source of trouble. This could be due to heat, or perhaps because the mechanism has become stiff as time passes. If this is the case, you can try cooling down the mechanism and lubricating handles and hinges. Or, it could be that the frame has slightly dropped or sagged and requires to be adjusted.

The misting could also be easily fixed. The rubber seals that hold the two panes of glass together will wear away over time. This is usually caused by the frames shifting slightly as they age and settling the particular packaging material that holds 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 remove moisture. This is a temporary fix and will need to be repeated. A better long-term fix is to put trickle vents in your frames. This will allow fresh air to circulate but won't let any of the warm air escape.
